Optimal Design and Operation of a Residential Hybrid Microgrid System in Kasuga City

This study aims to find the optimal configuration of an autonomous microgrid system which can be used to meet the electricity demand of a small community in the city of Kasuga, Fukuoka Prefecture, Japan. To this aim, an optimization model was developed, using the least cost perceptive approach and the load patterns of the residential end-uses. The proposed microgrid system in this study consists of a cluster of loads and micro sources such as the wind turbines, solar photovoltaic panels, battery storage, and a diesel generator. In this research, the effect of the demand response capabilities and patterns on optimal power generation from the proposed microgrid was investigated by introducing a standard demand pattern for a family, including three residents, living in a standard Japanese house in Kasuga city.
