| Summary: | The current electric grid, taken to the limit as much in size as in complexity, faces new challenges and needs of restructuring due to the growth of demand, power quality and emissions of greenhouse gases. Distributed grid architectures are acquiring a role increasingly important as alternative solutions to the centralized power grid. Among these architectures are the electric microgrids, low voltage distribution systems constituted by loads and distributed energy resources that, coordinated in an efficient way, allow to optimize the operation of the whole system. As part of current projects for the development of microgrids, the present project is a preliminary study for the design and sizing of a microgrid. This case study will be carried out on the School of Engineering of the University of Seville and it will consist of studying the current generation resources of the building, analysing its consumption pattern and proposing and sizing other energy resources based on renewable energy to reach a sufficient generation capability. After the elaboration of this project, a possible generation scenario for the previous purpose has been obtained. Generation capability of current generation resources (the Solar Cooling Plant and the Backup Generator Set) is well-known. In addition, making use of the consumption pattern obtained, a photovoltaic plant and a storage system have been sized taking a relationship of commitment between cost and storage capability into account. Among the most important conclusions, it can be mentioned, in relation with the theoretical part, the importance of studies in island mode and the lack of regulation for microgrids connection to the network in Europe. In relation with the case study, a yearly consumption pattern very representative has been obtained, current generation resources have been characterized and a photovoltaic plant for different scenarios has been sized, being the most interesting one in which there is storage. |
