Planning of micro-grid power supply based on the weak wind and hydro power generation

This paper presents the installation and verification processes of micro hydro power plant (MHPP) and micro wind power turbine (MWPT) for Kuromori Mountainous Region of Yamanashi Profecture based on the planning project of COE Program. This research focuses on the technologies to develop and utilize the natural energy in a region where the average wind speed (AWS) and water discharge are relatively weak just like the most other regions in this prefecture. micro-grid (MG) consisting of MHPP and MWPT sources are to be installed in existing power system (EPS). Contribution of MHPP and MWPT are determined by investigated wind and water characteristics on complex shaped mountainous land. Stability and reliability of the new hybrid power system are proved by using the compound controllers. Benefit from MG of MHPP and MWPT is proved by comparing the environmental and financial efficiency before and after installing the MG. This research, with the important practical significance, indicated that regions with relatively weak natural energy may be developed by applying the MG with possible compensation between micro-sources
