O presente trabalho visa propor uma metodologia para desenvolvimento e aplicação de um inovador emulador de redes elétricas inteligentes (REIs) para testes sistêmicos de funcionalidades de Smart Grids envolvendo dispositivos inteligentes (hardware) e sistemas de tecnologia da informação (software) em ambiente laboratorial. Além de dar uma dimensão da importância dos laboratórios de redes elétricas inteligentes para a pesquisa do tema, o levantamento bibliográfico apresentado neste trabalho permite concluir que as pesquisas envolvendo hardware-in-the-loop (HIL) tendem a concentrar suas análises nos equipamentos de hardware testados, como dispositivos de medição, equipamentos de potência (inversores de frequência e outros), dispositivos de controle e seus algoritmos e não em estudos que envolvam análises mais sistêmicas e interações dos dispositivos com sistemas de TI normalmente presentes nos Centros de Operação da Distribuição (COD), os quais cumprem papéis cada vez mais importantes nas funcionalidades de Redes Inteligentes. A metodologia proposta parte da premissa de que um ambiente para testes de funcionalidades de Smart Grids deve permitir análises sistêmicas, não apenas focadas nos dispositivos de controle de uma porção particular da rede ou sistemas de automação específicos, mas devem envolver a maior porção de rede possível e necessária para a correta representação das redes elétricas inteligentes. Neste sentido, a metodologia define e caracteriza os principais módulos e etapas de desenvolvimento de um emulador de redes elétricas inteligentes, ao mesmo tempo em que propõe soluções para os desafios de integração destes módulos, aplicando conceitos de hardware-in-the-loop, software-in-the-loop (SIL), e simulação com sincronização orientada a evento, além de propor soluções com simulação de sistemas de potência em regime permanente e hardware de baixo custo que permitiram o desenvolvimento do emulador de redes em laboratório de Smart Grid. As principais características do emulador de REIs desenvolvido e implementado no laboratório de Smart Grid, conforme a metodologia proposta, também são descritas neste trabalho. Por fim, são apresentados os casos teste, mais especificamente provas de conceito, envolvendo redes de teste IEEE/PES e redes reais das concessionárias do grupo EDP, financiador do projeto de implantação do laboratório no âmbito do Programa de P&D ANEEL, os quais serviram de base para a avaliação do desempenho do emulador e discussões finais sobre as contribuições da metodologia de desenvolvimento proposta neste trabalho. / This work aims to proposing a methodology for the development and application of an innovative Smart Grid emulator for systemic testing of Smart Grids functionalities involving intelligent devices and information technology systems in a laboratory environment. Besides demonstrating the importance of the Smart Grid for the subject research, the literature review clarifies that the research involving hardware-in-the-loop (HIL) tends to concentrate its analyses in the equipment under test, such as power devices, control devices and their algorithms. Instead, it should consider systemic studies involving the interaction of these devices with Operation Centre IT systems, so relevant to the Smart Grid functionalities. The proposed methodology is based on the premise that an environment for testing Smart Grids functionalities should allow systemic analysis instead of focusing only on control devices of a specific area or specific automation systems. Instead, it should involve a more detailed representation of the network that is necessary for the correct representation of the Smart Grid. In this direction, the methodology defines and characterizes the development stages and main modules of a Smart Grid emulator and proposes solutions for integration issues. It applies concepts of hardware-in-the-loop, software-in-the-loop (SIL), simulation with event-driven synchronization, besides steady-state power simulation and low-cost hardware solutions that enabled the development of the Power grid emulator at a Smart Grid laboratory.

Energy consumption in the form of fuel or electricity is ubiquitous globally. Among energy types, electricity is crucial to human life in terms of cooking, warming and cooling of shelters, powering of electronic devices as well as commercial and industrial operations. Therefore, effective prediction of future electricity consumption cannot be underestimated. Notably, repeated imbalance is noticed between the demand and supply of electricity, and this is affected by different weather profiles such as temperature, wind speed, dew point, humidity and pressure of the electricity consumption locations. Effective planning is therefore needed to aid electricity distribution among consumers. Such effective planning is activated by the need to predict future electricity consumption within a short period and the effect of weather variables on the predictions. Although state-of-the-art techniques have been used for such predictions, they still require improvement for the purpose of reducing significant predictive errors when used for short-term load forecasting. This research develops and deploys a near-zero cooperative probabilistic scenario analysis and decision tree (PSA-DT) model to address the lacuna of significant predictive error faced by the state-of-the-art models and to analyse the effect of each weather profile on the cooperative model. The PSA-DT is a machine learning model based on a probabilistic technique in view of the uncertain nature of electricity consumption, complemented by a DT to reinforce the collaboration of the two techniques. Based on detailed experimental analytics on residential, commercial and industrial data loads, the PSA-DT model with weather profiles outperforms the state-of-the-art models in terms of accuracy to a minimal error rate. This implies that its deployment for electricity demand planning will be of great benefit to various smart-grid operators and homes. / School of Computing / M. Sc. (Computer Science)

Depuis son invention, l'électricité joue un rôle essentiel dans notre vie quotidienne. L'apparition des premières installations de production d'électricité à la fin du XIXème siècle a ouvert la voie au système électrique et à ses sous-systèmes. Les consommateurs d'énergie électrique exigent un service fiable en termes de stabilité et de sécurité du réseau électrique. Depuis la libéralisation des marchés, les producteurs d'énergie électrique, les fournisseurs de services publics et d'équipements, en tant qu'acteurs principaux, suivent une tendance émergente pour satisfaire les demandes des consommateurs. Cette tendance implique l'amélioration des technologies, l'innovation et le respect des normes et des réglementations gouvernementales. Tous ces efforts ont été qualifiés de concept de réseaux intelligents (Smart Grid en anglais) qui évolue pour répondre aux demandes futures.Les sous-stations numériques modernes et futures façonnent des nœuds essentiels dans le réseau électrique, où la stabilité du flux d'énergie électrique, la conversion des niveaux de tension et la protection de l'équipement du poste de commutation figurent parmi les principaux rôles de ces nœuds. La norme prometteuse CEI 61850 et ses composants apportent de nouvelles fonctionnalités aux systèmes d'automatisation des postes. L'utilisation de la communication Ethernet dans ces systèmes réduit la quantité de connexions câblées qui réduit l'encombrement de l'équipement de la sous-station, des dispositifs et de leur câblage.L'intégration des nouvelles fonctionnalités CEI 61850 au niveau des sous-stations requiert des compétences multidisciplinaires. Par exemple, considérons les tâches de protection et de contrôle de la puissance d'un côté et les technologies de l'information et de la communication de l'autre. La dépendance entre les fonctions d'automatisation des sous-stations et les réseaux de communication à l'intérieur d'une sous-station pose de nouveaux défis aux concepteurs, intégrateurs et testeurs. Ainsi, étudier la fiabilité des fonctionnalités du système, par exemple, les schémas de protection, exige de nouvelles méthodes d'essai où les méthodes conventionnelles ne sont pas applicables. Les nouvelles techniques devraient fournir des moyens d'évaluer les performances des systèmes conçus et de vérifier leur conformité aux exigences des normes.Afin d'améliorer la fiabilité du système conçu, ce travail vise à développer des méthodes pour tester les systèmes d'automatisation de sous-station CEI 61850, en particulier sur les processus et les niveaux de la baie, dans une plate-forme dédiée aux tâches de recherche. Cette plate-forme incorpore des dispositifs de pointe et des cartes de test qui aideront à observer simultanément les interactions dynamiques des transitoires de puissance et les perturbations du réseau de communication. Les données obtenues lors des tests expérimentaux seront utilisées pour diagnostiquer les défaillances et classer leurs causes afin de les supprimer et d'améliorer la fiabilité du système conçu. / Since its invention, Electricity has played a vital role in our everyday life. The appearance of the first power production facilities in the late nineteenth century paved the way for the electrical power system and its subsystems. Consumers of electric power demand dependable service in terms of power grid stability and safety. Since the liberalization of the markets, producers of electric power, utilities and equipment suppliers, as principal players, are following an emerging trend to satisfy consumers’ demands. This trend involves improving technologies, innovating and respecting standards requirements and governments’ regulations. All these efforts termed as the concept of the Smart Grid that is evolving to meet future demands.Modern and future digital substations shape essential nodes in the grid, where stability of electric power flow, converting of voltage levels and protecting switchyard equipment are among the primary roles of these nodes. The promising standard IEC 61850 and its parts, bring new features to the substation automation systems. The use of Ethernet based communication within these systems reduces the amount of hardwired connections that results in lowering footprint of substation equipment, devices and their cabling.Integration of the new IEC 61850 features at the substation levels requires multidiscipline competences. For instance, consider power protection and control tasks from one side and information and communication technologies from the other side. Dependency between substation automation functions and communication networks inside a substation brings new kinds of challenges to designers, integrators and testers. Thus, investigating the dependability of the system functionalities, e.g. the protection schemes, requires new methods of testing where conventional methods are not applicable. The new techniques should provide means to evaluate performance of designed systems and checking their conformance to the standards requirements.In order to improve the designed system dependability, this work aims to develop methods for testing the IEC 61850 enabled substation automation systems, especially on the process and the bay levels, in a platform dedicated for research tasks. This platform incorporates state-of-art devices and test-set cards that will help to simultaneously observe dynamic interactions of the power transients and communication network perturbations. Data obtained during the experimental tests will be used for diagnosing of failures and classifying their causes in order to remove them and enhance dependability of the designed system.

Dans un contexte de multiplication d’expérimentations de « réseaux électriques intelligents » (REI) et de « villes intelligentes » à travers le monde, cette thèse questionne les reconfigurations qui affectent l’action publique liée à l’énergie depuis l’émergence de ces innovations technologiques. À partir d’une analyse de l’instrumentation des politiques énergétiques et de la gouvernance de quatre démonstrateurs de « smart communities » au Japon, nous souhaitons saisir la reformulation du rôle de l’État et de ses modes d’interaction avec les collectivités territoriales et avec les acteurs privés. Nous défendons la thèse que la pratique de l’expérimentation tend à devenir un instrument privilégié de la conduite des politiques locales, en réponse à d’importantes transformations qui affectent les politiques énergétiques. En nous appuyant sur une analyse néo-institutionnaliste, nous montrons que l’introduction des REI est marquée par des permanences dans le processus d’élaboration des politiques publiques et dans les cadres cognitifs mobilisés, mais aussi par un « changement graduel transformateur » dans les instruments déployés. À travers l’étude des quatre premiers démonstrateurs de smart community mis en place entre 2010 et 2015 par le Ministère de l’Économie, du Commerce et de l’Industrie (METI) à Yokohama, Toyota, Kyōto Keihanna et Kitakyūshū, nous procédons à une analyse de l’influence de la pratique expérimentale sur la production de politiques énergétiques locales et sur les modes d’interaction entre l’État et les acteurs locaux. Il apparaît alors que la pratique expérimentale est appropriée par les acteurs locaux volontaristes comme un moyen de valoriser leurs « bonnes pratiques » et d’ériger leur territoire en vitrine de l’exemplarité. Cette démarche s’inscrit dans une perspective stratégique visant à capter les financements privés et publics, mais elle résulte aussi d’un repositionnement de l’appareil étatique visant à renforcer son contrôle au sein de politiques énergétiques territorialisées par la promotion d’expérimentations en phase avec ses stratégies. Nous mobilisons en particulier les notions de « méta-gouvernance » et de « gouvernement à distance » pour qualifier les dispositifs déployés par l’État pour conférer des marges de manœuvre aux acteurs locaux et accorder des concessions ponctuelles qui s’inscrivent dans ses perspectives stratégiques, tout en effectuant un contrôle sur ce processus afin de maintenir la structure du réseau. / As smart grids’ experiments and smart cities are spreading through the world, this doctoral thesis questions the reconfigurations that have been affecting public action about energy issues since the appearance of these technological innovations. Through an analysis of energy policy tools and case studies of the governance of four ‘smart communities’ demonstration projects in Japan, my goal is to understand how the State redefines its role and its process of interaction with local governments and private actors. My main contribution is to analyze the practice of experimentation as an emerging tool of local policies, in response to major transformation that affect energy policies. Based on a neo-institutionalist approach, I highlight that the introduction of smart grids is based on continuities in terms of policymaking process and cognitive frames, while the policy tools used to implement smart grids are characterized by a ‘gradual institutional change’. Through an analysis of the first ‘smart communities’ demonstration projects that have been implemented by the Ministry of Economy, Trade and Industry (METI) between 2010 and 2015 in Yokohama, Toyota, Kyōto Keihanna et Kitakyūshū, I study the influence of experimentations in the implementation of local energy policies and in the interactions between the State and local actors. My case studies show that proactive local actors took over experiment as a way of enhancing the exemplariness of their territory and “best practices”. From a strategic point of view, this approach aims at attracting public and private funding, but in an institutional perspective, it also reveals how the State positions itself in order to increase its control over territorialized energy policies by promoting experimentation projects according to its strategies. I use the notion of ‘meta-governor’ and ‘governing by distance’ as a way of describing the measures implemented by the METI and other ministries to give room for manoeuvre to local actors and to grant concessions that fits with their strategies, while controlling over this process in order to maintain the general structure of the grid.

Smart Grid research is growing around the world due to the need to replace the ageing old electricity grid with an intelligent, reliable electricity network. The smart grid aims at creating a reliable power distribution and efficient power usage in homes. One of the key issues focused in this project is providing real time energy feedback to users, which is minimal or non-existent in the current grid system. This thesis investigates about using smart TVs to provide real time energy feedback in homes. Since its introduction in 2009 smart TVs are growing in popularity in European market. To provide real time energy feedback on smart TVs three features are identified Smart TV application, ambilighting and push notification. The Human-centered design process is used for designing the Smart TV interface system using the identified features. A literature study is conducted to gather the user requirements for the smart TV interface. The information gathered during the study is used for the design and implementation of the interface prototype. As an example platform the Philips smart TV 2013 is chosen to demonstrate the various features that can be used to provide energy feedback. The usability of the Smart TV interface is evaluated with users and the results are recorded. The smart TV application, ambient lighting and push notification system in Smart TVs is demonstrated for providing real-time energy feedback. The interface is evaluated with users and results are discussed. The result suggests that Smart TVs can serve as an informational display in homes. The Smart TV interface should be interlinked with Smart Phone and Tablet applications to be effective, further the users prefer the Smart Phone over the Smart TV application to control the household devices. / The thesis work evaluates the potential of using smart TVs to provide real time energy feedback in homes. The results of the thesis showed that smart phone are the primary interaction medium suitable for home environment while smart TVs can serve as an informative medium to provide ambient feedback in homes. / praveenjelish@ymail.com +46727700788

Creative ways of utilising renewable energy sources in electricity generation especially in remote areas and particularly in countries depending on imported energy, while increasing energy security and reducing cost of such isolated off-grid systems, is becoming an urgently needed necessity for the effective strategic planning of Energy Systems. The aim of this research project was to design and implement a new decision support framework for the optimal design of hybrid micro grids considering different types of different technologies, where the design objective is to minimize the total cost of the hybrid micro grid while at the same time satisfying the required electric demand. Results of a comprehensive literature review, of existing analytical, decision support tools and literature on HPS, has identified the gaps and the necessary conceptual parts of an analytical decision support framework. As a result this research proposes and reports an Iterative Analytical Design Framework (IADF) and its implementation for the optimal design of an Off-grid renewable energy based hybrid smart micro-grid (OGREH-SμG) with intra and inter-grid (μG2μG & μG2G) synchronization capabilities and a novel storage technique. The modelling design and simulations were based on simulations conducted using HOMER Energy and MatLab/SIMULINK, Energy Planning and Design software platforms. The design, experimental proof of concept, verification and simulation of a new storage concept incorporating Hydrogen Peroxide (H2O2) fuel cell is also reported. The implementation of the smart components consisting Raspberry Pi that is devised and programmed for the semi-smart energy management framework (a novel control strategy, including synchronization capabilities) of the OGREH-SμG are also detailed and reported. The hybrid μG was designed and implemented as a case study for the Bayir/Jordan area. This research has provided an alternative decision support tool to solve Renewable Energy Integration for the optimal number, type and size of components to configure the hybrid μG. In addition this research has formulated and reported a linear cost function to mathematically verify computer based simulations and fine tune the solutions in the iterative framework and concluded that such solutions converge to a correct optimal approximation when considering the properties of the problem. As a result of this investigation it has been demonstrated that, the implemented and reported OGREH-SμG design incorporates wind and sun powered generation complemented with batteries, two fuel cell units and a diesel generator is a unique approach to Utilizing indigenous renewable energy with a capability of being able to synchronize with other μ-grids is the most effective and optimal way of electrifying developing countries with fewer resources in a sustainable way, with minimum impact on the environment while also achieving reductions in GHG. The dissertation concludes with suggested extensions to this work in the future.

The thesis INTI was founded by the members of the project, because they had a great common interest for development of smart electronic products, which today is classified as smart home products. The founders used their experience and knowledge that they had acquired in their three years at Halmstad University. INTI falls nothing short of the expectations they had prior to the start of the project. It will simplify everyday living and enhance comfort in one's own home by using location recognition. Today, there is a lot of competition between different markets that integrate with smart home products. Such as audio products, light units and security products. INTI is an automated solution where programming modules can identify the user’s location in order to create a system network. By identifying the location of the user, it’s possible to configurate the sound system and establish a follow-around system. The primary goal with this thesis is to connect the INTI system with two speakers and attain a functional follow-around system that adjust the volume according to the user’s position. The purpose of the thesis is to create a unique system that is affordable by todays standard and alleviate everyday life for the private consumer. / Examensarbetet INTI grundades i samband med projektmedlemmarnas stora intresse för den utveckling som har skett av elektroniska produkter till det som klassificeras som smarta hemprodukter idag.
