This thesis is a part of the master's in data science course at LTU. The core objective would be to build models that can do a short-term prediction of electricity energy consumption based on historical consumption data. With the increasing demand for electricity, forecasting electricity consumption is important and must be more accurate and closer to the actual values. As a part of this thesis, three different time series forecasting models are studied and experimented. The first model is based on an ensemble of Facebook prophet and XGBoost models together, the second model is based on deep learning neural network using Long short-term memory a Recurrent Neural Network, the third model is based on Convolution neural network. The performance of these three models is discussed and improvements needed, are also mentioned.These three models are trained with data from 2014-2019 and predictions are evaluated with 2020. As 2020 is the core of the COVID-19 pandemic season, offices were closed and this has impact on the model performance and evaluations. These impacts are also highlighted. Cross Industry standard process for Data mining methodology is followed in this thesis.

Carbon reduction commitments and renewable energy targets have become legal drivers of electricity policy in the UK. Meeting those targets will require a transition in the way that electricity is generated, supplied and consumed. This thesis argues that small-­‐scale renewable electricity technologies (<5MW) could have an important role in driving that transition. The thesis evaluates the role of the feed-­‐in tariff -­‐ a policy mechanism designed to stimulate the deployment of small-­‐scale renewable electricity technologies -­‐ in electricity system transition in the UK. The research is based on empirical information generated from 37 industry interviews, observations of industry and government meetings and events, and secondary analysis of consultation responses, publications and statistics from government and the energy regulator, Ofgem. The analysis is structured with a framework that draws on transition theory and breaks down the findings into a niche (micro/developing) level, a regime (incumbent electricity system) level and a landscape (contextual) level. The thesis finds that the FIT has driven solar photovoltaic development and innovation at an unprecedented rate. The other renewable technologies supported under the FIT (wind, hydropower and anaerobic digestion) have not been as widely deployed. It is argued that additional policy support is required to overcome the non-­‐financial barriers that these technologies face. The thesis concludes that the role of the FIT in system transition has been to drive a level and pace of activity in the solar sector that has demonstrated the potential for alternative generation options. This has informed the politicised debate around electricity policy in the UK but it is argued that continued, broader, stable support is required if small-­‐scale renewable technologies are to have a positive role in electricity system transition. The research has relevance to both academic and policy circles focused on electricity policy, the decarbonisation of energy systems and socio-­‐technical system transitions.

The rebound effect refers to the phenomenon that energy savings from improvements in energy efficiency are lower than expected due to unintended second-order effects. Grasping specific mechanisms related to the rebound effect requires a good understanding of interactions between heterogonous agents on multiple markets. Otherwise, policies aimed at reducing energy use may render counter-expected and unforeseen consequences. In this paper, we propose a formal model, where technological change results from interactions on two markets: between consumers and producers in the market for final goods, and heterogeneous power plants in the electricity market. The analysis provides insights to the role of technological change, supply-demand coevolution, and status-driven consumption in explaining the rebound effect. The model is employed to compare effectiveness of economic policies aimed at reducing carbon emissions associated with production of consumer goods, namely: a tax on electricity and "nuclear obligations" to produce ten percent of electricity from nuclear energy.

Didžiulės elektros energijos vartojimo sąnaudos karkasinių namų gamyboje ganėtinai ženkliai didina gamybos savikainos kaštus, kas tiesiogiai atsiliepia įmonės pelnui. Medienos apdorojimo pramonės produkcijos galima pagaminti gerokai daugiau (arba pagaminant tą patį kiekį suvartoti mažiau elektros energijos), ne vien tik kuriant naujus didesnio našumo medienos apdirbimo įrenginius, bet ir racionaliai naudojant esamus, bei nuolat juos modernizuojant. Šiame darbe tiriamas karkasinius namus gaminančios ir statančios įmonės UAB „Namų statyba“ elektros energijos suvartojimas. Buvo siekiama nustatyti elektros energijos taupymo galimybes, iš įmonės elektros energijos suvartojimo pereiti prie energijos sunaudojimo normos vienam karkasiniam namui pagaminti. Atlikus tyrimą nustatyta, kurioje medienos apdirbimo operacijoje galima būtų sumažinti elektros energijos suvartojimą. Taip pat pateikiami pagrįsti elektros energijos efektyvumo didinimo būdai. / Engineering prime costs increase because of a great consumption input of electricity energy at framework house manufacture, which directly influence company profit. It is possible to produce much more wood processing industry output (or to consume less electricity energy while producing the same quantity), not only by creating new mechanisms of greater wood processing productivity, but also by racionally using the present ones and constantly modernizing them. The consume of electricity energy of the JSC „Namų statyba“ which specializes at manufacturing and building framework houses is being researched at this work. The target was to estimate the saving potencial of electricity energy and to come from company electricity energy consume to the norm of electricity energy that is necessary to build a single framework house. Wood processing operation at which it is possible to reduce electricity energy consumtion was estimated after the research. The reasoned methods how to increase the effectiveness of electricity energy are presented as well.

The solver is a computer code purely mathematic, ready to use, comprising numerical methods suitable to the analysis of interested phenomena. The user must develop an interface to the input and output data according to his personal interests, i.e., according to the problem being solved. The solver efficiency was tested in several steps. The beginning was over the solution of a first order ordinary differential equation, moving to computer tests with hypothetical power systems, increasing gradatively the computer simulation complexity. The obtained results revealed that this solver is very efficient in time domain transient and long-term stability studies, certifying that the power system dimension is either small- or medium-port. The resulting information from this work form the basis to the implementation of advanced solvers in a stability program. The goal is, independently of the power system size, provide a small processing time keeping the reliability of the numerical results. / O objetivo principal desta pesquisa é implementar e avaliar o desempenho numérico e computacional de um solver-numérico conhecido na literatura como DASSL, em um programa de estabilidade de fenômenos transitórios e de longo-termo, usado na resolução de sistemas de equações diferenciais e algébricas que representam a rede de energia elétrica e seus componentes. O solver-numérico é um programa computacional de caráter puramente matemático, já pronto para uso, contendo métodos numéricos que podem ser adequados às análises dos fenômenos de interesse. O usuário deve então desenvolver uma interface para a entrada e saída de dados de acordo com seu interesse, ou seja, de acordo com o problema a ser resolvido. A eficiência do solver foi testada em etapas. Começou-se por resolver uma simples equação diferencial ordinária de primeira ordem, passando-se para testes com modelos de energia elétrica hipotéticos, onde se aumentou gradativamente a complexidade das simulações computacionais. Os resultados obtidos revelaram que este solver-numérico é muito eficiente em estudos computacionais no domínio do tempo de fenômenos transitórios e de longo-termo, certificando-se que os sistemas elétricos sejam de pequeno-, ou de médio-porte. As informações decorrentes deste trabalho servirão de base para a implementação em um programa de estabilidade de solvers-numéricos mais avançados. A meta é, independentemente do tamanho do sistema simulado, ter um tempo de processamento pequeno sem perder a confiabilidade dos resultados numéricos.

Um dos aspectos importantes no processo é a interação entre a regulação exercida pelo estado e a gestão competitiva, fazendo com isso que haja necessidade de um equilíbrio dinâmico entre estes dois elementos. Uma maneira de vislumbrar este equilíbrio e aumentar a eficiência do sistema energético, com os setores da cadeia tornando-se negócios distintos, seria a gestão integrada e a proposição de iniciativas de fomento à cooperação ao longo da cadeia (estendida) de suprimentos, que se apresenta com enormes desafios devido à complexidade para articular agentes de diferentes naturezas e interesses distintos. Neste contexto, o presente trabalho tem como objetivo mostrar como a cadeia de suprimentos da indústria de eletricidade no Brasil está configurada, descrevendo suas transformações frente ao processo regulatório decorrente da reforma do setor elétrico e suas consequências em termos de impacto sobre a cadeia como um todo. A metodologia consiste em utilizar análises qualitativas e quantitativas, para mostrar que a análise sistêmica da cadeia de suprimentos de energia elétrica no Brasil caracteriza-se como instrumento conceitual e metodológico muito apropriado à identificação de potencialidades e fragilidades, as quais comprometem a eficiência do mercado competitivo. Com a descrição de todos estes aspectos a pesquisa pretende mostrar reais contribuições para as necessidades de planejamento na área, destacando-se o esforço na busca de integração e articulação dos componentes e processos do sistema energético mais relevantes à tomada de decisão, bem como a introdução de novos conceitos que se vislumbram promissores para o avanço do conhecimento na área / Abstract: The decision processes and institutional relationships along the stages of the brazilian electricity energy supply chain have been strongly changed during the reform process, thus requiring that restructuring be well fitted to the new hybrid environment (state and private) with market players, state companies and a regulator. One of the most important aspects in this process is the interaction among the state regulation and the competitive management, thus requering a dynamic equilibrium between these two players. A possible way to achieve this equilibrium and also increase the efficiency of the energy system, with separate businesses for each stage of the supply chain, could be the integrative management and the proposal of a set of initiatives to encourage the cooperation along the extended supply chain stages. In this context, this research work aims at presenting the current configuration of the brazilian electricity supply chain, with a description of the main changes after deregulation of the electric sector, as wel as its impacts on the supply chain as a whole. The proposed methodology includes qualitative and quantitative analysis, in order to show that the systemic analysis of the electricity energy supply chain is a conceptual framework very apropriated to the identification of potentialities and weakness that can pose risks to the efficiency in the competitive markets. With the description of all these aspects, this researck work aims at bring real contributions to the current planning needs in the area, with specific emphasis on the efforts to achieve integration and conexion among the most relevant components and processes of the energy system to decision making process, as well as the introduction of new concepts with potential to extend the present knowledge in this area / Doutorado / Planejamento de Sistemas Energeticos / Doutor em Engenharia Mecânica
