摘　　要：微电网中的储能系统是提高系统稳定性、补充因风电、光伏等供电缺失部分、很好地跟踪负荷变化、提高电能质量的重要组成部分。设计了微电网中蓄电池储能系统,包括双向DC-DC变换器、双向DC-AC变换器及控制器,通过仿真分析可知,所设计的储能系统具有较好的充放电性能,基本实现了微电网对储能环节的要求,能够保证在分布式电源发生波动等输出功率不稳定时用户端的电能质量较好。Energy storage system in microgrid is an important part of improving system stability, adding the missing part of wind power and photovoltaic power supply, tracking load changes very well and improving power quality. A microgrid battery energy storage system was designed, including bi-directional DC-DC converter, bi-directional DC-AC converter and controller. The simulation analysis shows that the designed energy storage system has good charge-discharge performance, realizes the requirements of microgrid for energy storage and can ensure good power quality of the client when the output power is unstable such as the fluctuations of distributed power.
