摘　　要：光伏发电、风力发电等可再生能源发电系统的波动性、间歇性和不可预测性会对微电网的运行特性产生一定的影响,包括电压波动、闪变、谐波,频率波动以及柴油发电机输出功率大幅波动、定子电流三相不平衡等。电池储能系统(BESS)由于其快速的有功/无功响应特性,可用于微电网中平滑分布式电源的输出功率,从而改善微电网的运行状况。首先研究了可再生能源发电系统的随机波动对微电网运行状况的影响,提出了采用P/V控制调节可再生能源发电系统的输出功率,同时稳定微电网母线电压的控制策略。并针对一种典型的微电网结构,仿真验证了BESS对微电网运行状况的改善作用。The intermittent and unpredictable of renewable energy generations such as PV and wind turbine may affect the op- eration performance of micro-grid including frequency, voltage and diesel generator operation state. And battery energy storage system （BESS） is usually equipped in micro-grid to mitigate the fluctuations of distributed generator output. This paper pres- ents a P/V control strategies in a typical micro-grid composed of diesel generator, asynchronous wind turbine, PV generator, and BESS. Simulation proves that the operation performances of micro-grid could be greatly enhanced by BESS under the con- trol strategies presented in this paper.
