碩士 / 國立高雄科技大學 / 電機工程系 / 107 / This thesis presents control strategies that involve a battery energy storage system (BESS) for a microgrid power system on an offshore island with a high penetration of PV renewable energy. An energy management system performs the supervisory control and data acquisition of diesel generators (DGs), distribution feeders, a PV system and the BESS. The simulation uses mathematical models of the diesel generators, the PV system and the BESS. The parameters of the generator models are validated using real test data concerning the microgrid response to the power control of the BESS to simulate a step change in the system load demand. An expert system is embedded in the iEMS to support decision-making for fast discharging of power from the BESS to improve the transient stability of the grid under large disturbances, such as the tripping of the DGs or the PV farm. To support the economic dispatch of the microgrid, a strategy of peak shaving and valley filling of the net system load profile is perform to improve the system load factor using the BESS; the strategy considers hourly forecasting of the system loading and solar power generation. The results of a system simulation and field test demonstrate that the proposed control strategies that involve the BESS significantly improve the power service quality and transient stability of the system in the island microgrid, which has a high penetration of renewable generation.
