摘要：
In order to solve the power supply reliability problems of wind/biomass/diesel/battery stand-alone microgrid (SAMG) under various operational modes, the output limitation control of wind turbine generator (WTG), the dynamic range control of diesel engine (DE), the improved charge and discharge control of battery energy storage system (BESS), the auxiliary frequency control of biomass power generator (BPG) and the two-stage spinning reserve strategy of SAMG were designed respectively based on the system functional orientation of different power equipment, and the real-time operational control method of SAMG based on mode switch was proposed subsequently, which can be used not only to realize smooth transition but also to keep stable operation under both normal and urgent conditions, so as to effectively exert the technical characteristics of diversified distributed power supply equipment and improve the comprehensive efficiency of SAMG. The case analysis results under typical working conditions verify the validity of the proposed method. © 2019, Electrical Technology Press Co. Ltd. All right reserved.
