La thèse propose d’abord un cadre général pour l’analyse de l’incertain durant les différentes phases du processus de planification énergétique à long terme à base de modèles de villes ou territoires (IEPCT). Il inclut des critères d’évaluation de la qualité d’une démarche IEPCT. Puis deux méthodes d’analyses de l’incertain sont proposées pour les activités de modélisation et de scénarisation du système énergétique : l’une basée sur l’échantillonnage aléatoire (PRSUA) et l’autre sur les scénarios flous (FSUA). Leur implémentation sur des cas a permis de montrer leur faisabilité et leur performance du point de vue des critères de qualité. La méthode PRSUA est plus gourmande en données, elle est plus adaptée à la planification sectorielle court moyen terme et tandis que FSUA convient plus à la planification long terme intersectorielle.Enfin une méthode pour la réalisation de l’ensemble des activités liées à la structuration d’un problème de planification spécifique (IMMA) est proposée. / The Phd first proposes a methodological framework for addressing different types of uncertainty within long range ntegrated energy planning for cities and territories (IEPCT) processes which includes requirements and quality factors. Second, two methods for uncertainty analysis of modelling tasks are proposed. One approach is probabilistic random sampling approach (PRSUA) another one is fuzzy scenario approach (FSUA). Compared to FSUA, the PRSUA framework is more data intensive. PRSUA is more suitable for short or midterm sector specific domain analysis, FSUA is more appropriate for long range cross sectoral integrated planning.Third it is proposed an innovative approach (IMMA) for supporting not only uncertainties in IEPCT first phase but also all other tasks relevant to this planning phase. Implementation of IMMA in Singapore shows that it can address all identified tasks and help developing requirements for innovative solutions.

O Planejamento Energético tradicional geralmente privilegia os custos econômicos dos recursos energéticos, relegando ao segundo plano questões políticas, sociais e ambientais. Este trabalho pretende estimular a mudança desta abordagem através da proposição de um modelo de caracterização de recursos energéticos integrando todas essas quatro dimensões. São dois seus objetivos: o fornecimento de uma metodologia para avaliar o custo global dos recursos energéticos e de outra para estimar o potencial de tais recursos. Para facilitar o processo de avaliação, o modelo sugere o uso da ACC - Avaliação de Custos Completos, a qual permite a análise qualitativa e quantitativa de custos, reduzindo a necessidade de dados quantitativos, limitados em certos casos. Ilustra-se a aplicação do modelo com um exemplo de caracterização dos recursos na região de Araçatuba, localizada no Oeste Paulista. Os resultados revelam que, quando considerados os custos globais, a adoção de recursos renováveis apresenta grande competitividade, ao contrário de outros que, apesar de serem economicamente atraentes, não apresentam custos globais aceitáveis. / The Traditional Energy Planning usually favors technical-economic costs, relegating political, social and environmental issues to a less important level of analyses. This work tries to encourage a change in such approach by elaborating a model of energy resources characterization integrating all four dimensions - environmental, political, social and economic. The model aims at two objectives: providing a method of assessing the global cost of energy resources and estimating its potential considering the limitations provided by these dimensions. The integration of distinct elements constitutes a complex and tricky activity that can result in inaccurate results if not taken carefully. To minimize this complexity, the Model suggests the use of the Full Cost Accounting - FCA - method, which allows the consideration of quantitative and qualitative costs, reducing the demand for quantitative data, limited in some cases. The Model has been applied in the characterization of the region of Araçatuba, located in the western part of the state of São Paulo, the most populated state in Brazil. The results reveal that the adoption of renewable sources is quite attractive, especially when global costs are taken into account. On the other hand, other resources don\'t present acceptable global costs despite being economically attractive.

Urban energy system planning can play a pivotal role in the transition of urban areas towards energy efficiency and carbon neutrality. With the building sector being one of the main components of the urban energy system, there is a great opportunity for improving energy efficiency in cities if the spatio-temporal patterns of energy use in the building sector are accurately identified. A bottom-up engineering energy model of buildings, known as urban building energy model (UBEM), is an analytical tool for modeling buildings on city-levels and evaluating scenarios for an energy-efficient built environment, not only on the building-level but also on the district and city-level. Methods for developing an UBEM vary, yet, the majority of existing models use the same approach to incorporating already established building energy simulation software into the main core of the model. Due to difficulties in accessing building-specific information on the one hand, and the computational cost of UBEMs on the other hand, simplified building modeling is the most common method to make the modeling procedure more efficient. This thesis contributes to the state-of-the-art and advancement of the field of urban building energy modeling by analyzing the capabilities of conventional building simulation tools to handle an UBEM and suggesting modeling guidelines on the zoning configuration and levels of detail of the building models. According to the results from this thesis, it is concluded that with 16% relative difference from the annual measurements, EnergyPlus is the most suitable software that can handle large-scale building energy models efficiently. The results also show that on the individual building-level, a simplified single-zone model results in 6% mean absolute percentage deviation (MAPD) from a detailed multi-zone model. This thesis proposes that on the aggregated levels, simplified building models could contribute to the development of a fast but still accurate UBEM.

This thesis addresses industrial energy issues from a production economic perspective. During the past decade, the energy issue has become more important, partly due to rising energy prices in general, but also from a political pressure on environmental awareness concerning the problems with climate change. As a large user of energy the industry sector is most likely responsible for a lot of these problems. Things need to change and are most likely to do so considering current and assumed future governmental regulations. Thus, the energy intensive process industries studied and focused on in this thesis exemplify the importance of introducing a strategic perspective on energy, an appropriate approach for planning, as well as the possibilities of including energy issues in a production and supply chain planning model. The thesis aims to provide models, methods and decision support tools for energy related production and supply chain planning issues of relevance for process industries as well as for other energy intensive industries. The overall objectives are to analyze the strategic importance of energy management, production and supply chain planning, and the opportunities provided when energy is included in a production and supply chain planning model. Three different studies are carried out, analyzed, and presented as in this thesis. The first study is a case study at a specialty chemicals company and resulted in the first paper. Since the energy issue is not only a cost issue driven by supply and demand, but also a political issue due to its environmental aspects, it is likely to believe that political influence and especially continuity will have escalating effect on the energy intensive process industry sector. Thus, the strategic dimension of energy is highly relevant in this thesis. The importance of organizational integration, having a main responsible person, locating core business, and political continuity are addressed as prerequisites for including energy into the corporate strategy. Regarding long term profitability, the importance of correctly utilizing the energy system by appropriate energy planning and with respect to energy efficiency and effectiveness in both flexibility and investment issues are addressed. Further on, the quest of finding alternative revenue while striving for a proper exergy usage is addressed. The second study is a multiple case study with four different case companies involved; pulp, specialty chemicals, specialty oils, as well as a pulp and paper company. The need for improved production and supply chain planning is also addressed where for instance the lack of planning support for process industries is still an area of improvement. The production and supply chain planning in process industries is found to be rather poor compared to regular manufacturing companies. The planning methods found are often tailor made and adapted to the individual characteristics that are typical for many process industries. It has further on been difficult to distinguish similarities and differences among process industries regarding these planning issues and thus hard to generalize. The third study focuses on mathematical modelling and programming developing a combined supply chain and energy optimization model for a pulp company. Taking the first papers together there are reasons to believe that a planning and optimization model that take energy aspects in consideration, as a previously missing link, will contribute to improve the operations in process industries. A clear impact of involving energy issues into the supply chain planning is shown. The results show that a different production schedule is optimal when the energy issues are applied, and depend on, for instance, variations in energy prices such as the one for electricity. This is shown by using a model for a supply chain where the energy flow, and especially the utilization of by-products, also is involved.

ABSTRACT Cities throughout Asia have experienced unprecedented economic development over the past decades. In many cases this has contributed to their rapid and uncontrolled growth, which has resulted in a multiplicity of problems, including rapid population increase, enhanced environmental pollution, collapsing traffic systems, dysfunctional waste management, and rapid increases in the consumption of energy, water and other resources. The significant energy use in cities is not very well perceived in Asian countries. Although a number of studies into energy consumption across various sectors have been conducted, most are from the national point of view. Energy demand analysis is not considered important at the level of the city. The thesis is focused on the dynamics of energy utilization in Asian mega-cities, and ultimately aims at providing strategies for maximizing the use of renewable energy in large urban systems. The study aims at providing an in-depth understanding of the complex dynamics of energy utilization in urban mega-centers. An initial general analysis is complemented by a detailed study of the current situation and future outlook for the city of Bangkok, Thailand. An integrated approach applied to the study includes identification of the parameters that affect the utilization of energy in mega-cities and a detailed analysis of energy flows and their various subsystems, including commercial, industrial, residential and that of transportation. The study investigates and evaluates the energy models most commonly used for analyzing and simulating energy utilization. Its purpose is to provide a user-friendly tool suitable for decision-makers in developing an energy model for large cities. In addition, a Multi-Criteria Decision-Making (MCDM) process has been developed to assess whether or not the energy systems meet the sustainability criteria. A metabolic approach has been employed to analyze the energy flow and utilization in selected Asian mega-cities, including Bangkok, Beijing, Shanghai, and Tokyo. The approach is applied to measure the majority of indirect energy flows or the energy embodied in the flows of goods and services involving the residents of those cities. Since the function of cities is to serve the lives of the residents, indirect energy consumption could be regarded as being of equal importance as that of direct energy use. The essence of embodied energy is that an indirect reflection upon behavior following direct energy consumption. It can illustrate how a city relies on the outside, for example other cities, countries, etc. and provides some interesting information that cannot be easily drawn from the direct energy demand. The study reveals that the indirect energy demand is more significant than the direct energy demand in Bangkok, Shanghai, and Tokyo, while direct energy demand is greater than the indirect energy demand in Beijing. This can be explained by the fact that Bangkok, Shanghai, and Tokyo have a greater reliance upon the outside in terms of energy demand. The Long-range Energy Alternative Planning (LEAP) system has been selected to perform Bangkok energy modeling. In a Bangkok case study a range of policy interventions are selected and how these would change the energy development in Bangkok by the year 2025 is examined. Different policies can be grouped by the sectors analyzed. The only supply-side policy considered meets an existing target of having 10% of electricity generated from renewable sources. The study period for the model started in 2005 and ends in 2025, with the year 2000 taken as the base year. The proposed scenarios were evaluated using the MCDM approach to rate their sustainability. Team members found that this method provided a methodology to help decision-makers to systematically identify management objectives and priorities. / QC 20101123

Há um cenário de agrave na indústria de energia elétrica no Brasil, por escassez de energia afluente na produção hídrica, exigindo maior acionamento térmico. Para o futuro, usinas predominantemente a fio dágua, que estão sendo inseridas, estarão pronunciando ainda mais essa necessidade. Por força da estruturação térmica, sobrarão mais emissões de gases de efeito estufa - GEEs e consumo de recursos fósseis por unidade de energia elétrica produzida. Este estudo visa testar a possibilidade de construção de um cenário futuro, eleito 2050, de fornecimento de energia elétrica no país, balizado na aceleração do uso das fontes renováveis, premissa postulada como alinhamento à busca de desenvolvimento sustentável para o país. É utilizada a pesquisa, análise e síntese, com abordagem sistêmica, e aplicação de indicadores eleitos fundamentais para alcance do objetivo. São sistematizados dados e informações existentes em diferentes tipos de documentos elaborados por autores e organizações nacionais e internacionais, e nos planos governamentais de expansão da produção de energia elétrica. A partir do referencial teórico metodológico adotado, os resultados obtidos demonstram que é possível estabelecer um planejamento de longo prazo baseado no uso renovável dos recursos de que o país dispõe, com menores pressões socioambientais, consumos de fósseis, e emissões de gases de efeito estufa, por unidade de energia produzida. São obtidas maiores participações de fontes renováveis com menor participação da fonte hídrica, e menores participações de emissões de gases de efeito estufa e de consumo de óleo combustível. Sem incorrer em aumento nos custos de produção. Resulta um sistema descentralizado, híbrido, com maior expansão das fontes térmicas renováveis, eólica e solar, maior participação de produção independente cogeração, autoprodução, e geração distribuída e menor carga na rede de transmissão, comparativamente ao cenário atual. / There is an aggravated prospect in the Brazilian electric energy industry, due to a shortage of affluent energy in the hydric production, requiring a greater thermal use. For the future, the insertion of hydroelectric power plants predominantly without reservoirs will make this need even more evident. Due to the thermal structuring, there will be more emissions of greenhouse gases (GHGs) and consumption of fossil resources per unit of electric energy produced. This study aims to test the possibility of building a future setting, elected 2050, of electric energy supply in the country, beaconed on the acceleration of the use of renewable sources, premise postulated in alignment with the pursuit of sustainable development for the country. The research, analysis and synthesis is adopted, with a systemic approach, and applying the indicators elected as paramount to reach the goal. Data and information from different types of documents produced by international and national authors and organizations as well as governmental plans of expansion of electric energy production were systematized. From the theoretical and methodological framework adopted, the results obtained have shown that it is possible to establish a long term plan, based on the use of the available resources, with decreased social and environmental pressure, fossil consumption, and emission of GHGs per unity of energy produced. A greater participation of renewable sources is achieved, while the participation of hydric sources, the emissions of GHGs and consumption of oil-fuels are reduced. There is no increase in the production costs. The result is a decentralized, hybrid system with larger expansion of renewable thermal, wind and solar sources, larger participation of independent production co-generation, auto-generation and distributed generation and a diminished load on the transmission network, compared to the current scenario.

A avaliação de sustentabilidade emergiu a partir da pesquisa e da prática em várias áreas do planejamento e gestão como uma abordagem ou como um novo instrumento para suporte a decisões direcionadas à promoção da sustentabilidade. Uma dessas áreas é a Avaliação de Impacto, que tem um consistente histórico na busca por subsidiar processos decisórios. A partir desse referencial, e tendo em vista a crescente importância do etanol de cana-deaçúcar nas discussões sobre a sustentabilidade na área de energia, esta tese propõe procedimentos para o planejamento da oferta de etanol de cana-deaçúcar apresentada no Plano Decenal de Expansão de Energia. A análise indicou que o formato atual do PDE é muito mais próximo de um estudo de potencial técnico do que de um plano, uma vez que não são estabelecidos caminhos entre a situação atual e a situação desejada, essenciais em planejamentos. As principais contribuições identificadas a partir da avaliação de sustentabilidade estão relacionadas ao fortalecimento do papel do planejamento, incluindo o aprimoramento dos métodos de avaliação de impactos e de integração de temas, à ampliação da gama de alternativas e opções apresentadas aos tomadores de decisão, evidenciando recursos necessários e consequências de cada alternativa de forma a subsidiar de fato a seleção de uma ou outra estratégia, e à valorização do pluralismo no processo de elaboração e decisão do PDE. A análise indica que o arcabouço teórico oferecido pela avaliação de sustentabilidade se mostra adequado para auxiliar no desenho de um novo modelo de planejamento, capaz de fortalecer o PDE e avançar na inserção de princípios de sustentabilidade ao longo do processo. Como conclusões, a pesquisa reitera que a inserção de princípios de sustentabilidade em planejamentos e processos decisórios é parte fundamental na consolidação de um novo modelo de desenvolvimento e que, no caso do etanol de cana-de-açúcar, a abordagem da avaliação de sustentabilidade oferece uma visão mais plural e sistêmica em relação ao que é feito atualmente, o que é ideal para o avanço em um caso emblemático de transição energética. / Sustainability assessment has emerged from both research and practice in several areas of planning and management as either an approach or a new tool for supporting decision-making towards sustainability. Impact Assessment is one of such areas and has a consistent history in supporting decision-making. Drawing from this field and considering the increasing importance of sugarcane ethanol sustainability issues in the energy sector, this thesis proposes procedures for planning the supply of sugarcane ethanol in the Decennial Energy Expansion Plan. The analysis has indicated that the current format of the PDE seems more a restricted study of technical potential instead of a plan, since paths between the current situation and the desired situation, essential to planning, have not been established. The main contributions identified from the sustainability assessment application are related to the strengthening of the role of planning, including improvements in the methods for assessing impacts and integrating issues, the expansion of the range of alternatives and options presented to decision makers, highlighting the necessary resources and consequences of each alternative to support the selection of one or another strategy, and the embracement of pluralism along the PDE process and decision making. According to the analysis, the theoretical framework offered by sustainability assessment is appropriate to assist the design of a new planning model, strengthening the PDE and advancing the integration of sustainability principles throughout the process. In conclusion, the research highlights the importance of including sustainability principles in the planning and decision-making processes so that a new development model can be outlined. In the sugarcane ethanol case, sustainability assessment offers a more plural and systemic approach in comparison to what has been done, which would be ideal for advancements in this emblematic case of energy transition.

A geração termelétrica a partir da biomassa proveniente do setor sucroenergético brasileiro, além de ser vista como opção para investimentos no setor de energias renováveis, pode contribuir com o suprimento de energia mantendo aspectos inerentes às vantagens sociais, estratégicas e ambientais que o favorecimento de um setor genuinamente desenvolvido no Brasil pode atribuir à matriz de energia elétrica. O objetivo principal deste trabalho é analisar o potencial adicional de energia elétrica que pode ser gerado a partir de recursos do setor sucroenergético. Os objetivos específicos estão em determinar e dimensionar os possíveis combustíveis para geração termelétrica no setor sucroenergético, em determinar quais rotas tecnológicas possibilitam o aumento da geração de energia e em quantificar a geração específica bruta de energia para cada tecnologia selecionada. O método consiste na realização de revisão bibliográfica para alocar o tema de estudo e pesquisa, com posterior elaboração de pesquisas documentais com o intuito de reunir dados e estimativas necessárias ao desenvolvimento do cálculo, coletando dados em publicações de institutos, entidades, empresas e consultores (dados de estimativas de produção de cana-de-açúcar para o período projetado e a definição dos recursos combustíveis e dos recursos tecnológicos). A seguir, para cada tecnologia de geração de energia elétrica, são apresentados arranjos com seus respectivos balanços de energia, índices de geração específica bruta de energia para as condições de cogeração e de geração de energia elétrica pura, vantagens, desvantagens e a inserção destas tecnologias ao longo do período estimado. Os resultados apontam que a expansão da produção de cana-de-açúcar, baseada na expansão agrícola e no aumento da produtividade, bem como o incremento tecnológico dos sistemas termelétricos de potência disponíveis comercialmente para o setor sucroenergético podem permitir a projeção de cenários com 26 GW de capacidade instalada com a utilização do bagaço e 33 GW com a inserção de palha. A importância deste trabalho está relacionada com a apresentação do estado da arte da tecnologia disponível para a geração termelétrica a partir do setor sucroenergético, pelo fato de apresentar os índices de geração específica para diferentes cenários de disponibilidade combustível e de tecnologias aplicáveis e por permitir análises entre os grupos tecnológicos e as biomassas disponíveis para a geração. / The biomass power generation in the Brazilian sugar & ethanol industry, besides being seen as an option for investments in the renewable energy sector, may contribute to the energy supply while maintaining aspects related to social, strategic and environmental advantages that the support of a sector genuinely developed in Brazil can attribute to the electricity matrix. The main purpose of this study is to analyze the surplus electricity that can be generated from resources of the sugar & ethanol industry. The specific aims are to determine and measure the potential fuels for power generation in the sugar & ethanol industry, to determine which technological routes enable an increase in the power generation and to quantify the specific gross power generation for each selected technology. The method consists of conducting a literature review in order to place the subject of study, with further development of documentary research in order to collect data necessary for developing the calculation, collecting data in publications from institutes, organizations, companies and consultants (sugarcane production data estimates for the foreseen period of study and the definition of fuel and technology resources for power generation). Afterwards, for each power generation technology, arrangements are presented with their respective energy balances, the specific gross power generation for the cases of process cogeneration and power generation stand-alone, the advantages, disadvantages and the inclusion of these technologies over the projected period. The results show that the expansion of production of sugarcane, based on agricultural expansion and increased productivity as well as the technological improvement of commercially available power generation systems for the sugarcane industry may allow scenarios with 26 GW of installed capacity using the sugarcane bagasse and 33 GW with the insertion of the sugarcane straw. The significance of this work is related to the presentation of the state of the art technology available for the thermoelectric generation from sugarcane industry. It is also connected to the fact of presenting an index of specific power generation for different scenarios of fuel availability and applicable technologies as well as enabling analysis of technological groups and available biomass for power generation.

O suprimento - produção, transmissão, distribuição - e uso da energia é essencial na busca do desenvolvimento sustentado -DS-. As necessidades de uma visão completa (DS, Energia e Meio Ambiente) do problema e dos métodos de avaliação que ponderem completa e complementarmente os aspectos técnicos, sócio-ambientais, sócio-econômicos e sócio-políticos envolvidos, requerem modificações na forma tradicional de estudar e planejar a questão energética. Pelo que as abordagens, metodologias e técnicas de planejamento do setor elétrico devem incorporar aspectos globais e particulares (convencionais e não), enfatizar alternativas não tradicionais, e permitir participação dos envolvidos-interessados, de uma forma ou outra, no processo. O PIR (Planejamento Integrado de Recursos) diferencia-se do planejamento tradicional na classe e na abrangência dos recursos considerados, na participação real dos proprietários e não proprietários dos recursos, dos organismos envolvidos no plano de recursos, e nos critérios da seleção das alternativas. Este trabalho apresenta a importante etapa de estabelecimento de fundamentos e uma primeira etapa de implementação de processos e estudos relativos ao PIR, desenvolvidas no ambiente do GEPEA (Grupo de Energia do Departamento de Engenharia de Energia e Automação Elétricas da Escola Politécnica da Universidade de São Paulo).No sentido de enfocar o PIRse-PIR para o setor elétrico- (ou PIR indistintamente), como um processo contínuo e elaborado com base no DS. Pelo que também se faz uma análise do meio ambiente e da energia como um todo, porém sempre centrado na EE (Energia Elétrica). Apresentando ainda, como suporte da análise, o estado atual do planejamento do setor elétrico em geral e em particular do Brasil. Apresenta-se ainda como fundamentos estabelecidos e colhidos ao longo do tempo, uma série de atividades desenvolvidas no período, que permitem estabelecer uma linha de pesquisa específica (o PIR) e a sua aplicabilidade, inclusive fora do ambiente regulamentar. Neste sentido, destacam-se (quase seqüencialmente) atividades como: EE para o DS; CONSERVUSP (conservação de energia na USP); etapa atual do PIRMPP (Planejamento Integrado de Recursos para a Região do Médio Paranapanema); e o SAGe (Sistema de Análise Geo-energético); dentre outros. Finalmente, incluem-se considerações sobre o PIR na atualidade, e ainda propostas esquemáticas em torno de um possível PIR genérico no Brasil. / Energy supply and use - production, T&D -, is essential for attaining the sustainable development -SD-. The needs of an integrated vision (SD, Energy and the Environment) of the problem; and of developing methodologies that holistic and completely weight the technical, environmental, socioeconomical, and sociopolitical aspects involved, require modifications in the traditional way of studying and planning (the energy system). Due to that, the planning approach, methodologies and technics of the electrical sector need to incorporate global and specific aspects (conventional or not), underline non traditional alternatives, and to permit the stakeholders participation in the process. The IRP (Integrated Resource Planning) is different from the traditional planning in the type and scope of the considered resources, in the real participation of stakeholders (owners and not owners of the resources), in the organisms involved on the resource plan, and in the criteria to select the options. This work presents the important step of establishing the fundamentals and a first step of implementing processes and studies related to the IRP in the GEPEA’s (Group of Energy of PEA -Department of Electrical Energy and Automation Engineering) environment. This in the sense of focusing IRPes -IRP of electrical sector - (or IRP indistinctly), both as a continuous process and developed with basis in the SD concepts. Consequently, it presents energy and environmental analyses as a whole, but centered in the EE (Electrical Energy). Introducing also, as a support of the analysis, the present statement of the electrical sector planning ingeneral, and in the particular, the Brazilian one. In addition, it is shown, like fundamentals, a series of activities developed during the completion of this work, that permit to establish one specific line of research (the IRP), including the proposal of the IRP out of the regulator and/or regulation environment. Therefore (in the same sequential manner) activities such as: EE for de SD; CONSERVUSP (energy conservation in the USP); present stage of the PIRMPP (integrated resource planning for the Paranapanema region); and including the SAGe (geoenergy analysis system); among others, are emphasized. Finally the work includes some considerations on the present IRP world situation and presents a schematic proposal around a possible Brazilian IRP.
