Design and operation of microgrid with renewable energy sources and energy storage system: A case study

Modern power system experts attentions have been diverted from the centralized power generation to the microgrid system due to availability of high potentials of renewable energy resources. Microgrid is designed so that a little dependency on national grid. In this paper a microgrid design guidelines, procedures and techniques have been presented where the renewable energy resources are available in abundant. A case study of an educational institute with academic blocks has been taken for which a microgrid is designed with available resources (solar and wind) and energy storage system. Optimal sizes and sites for wind and solar PV units were investigated using an analytical approach. The proposed scheme presents the effective utilization of energy sources with a ranked load distribution system. The results obtained in this research work clearly demonstrates the cost effectiveness of microgrid compare to the dependency on power utility grid. Cost analysis of the microgrid with proposed renewable sources, batteries and diesel generators has also been carried out.
