Feasibility study of microgrid village with renewable energy sources

Abstract

The exploitation of distributed energy resources and problems associated with islanded energy grids are important in optimizing sustainability of electricity supply, where microgrids play a major role in the decentralized and dispersed production. As defined, a microgrid is a group of interconnected loads and distributed energy resources within clearly defined electrical boundaries that acts as a single controllable entity with respect to the grid. Can connect and disconnect from the grid to enable it to operate in both grid-connected or island mode (remoted). The main focus of this study is the evaluation of a remoted microgrid of Vorias village, located in the inland of Crete island. Considering the household, agricultural and industrial loads of the village, were chosen RESs, such as wind turbines, photovoltaic panels and occasionally, small storage units in case of excess production. Energy Storage and small biomass generators are proposed. The co-production of RESs aims the 100% energy independence, considering economic and environmental impact boundaries. To maintain the highest degree of reliability and security of the operating system, the designed potential project is also represented through Geographical Information Systems (GIS) in map forms (wind and solar energy potential maps). The region of Vorias village presents intense relief that justifies the installation of both wind and solar parks, regardless of the possibility of individual RESs installation in the settlements of the region.
