摘　　要：微网中太阳能等一次能源发电易受自然条件因素的影响,导致输出功率很不稳定,针对上述问题,对储能系统作为微电网主要电源的主从控制策略进行了研究。以发展技术成熟的蓄电池为储能元件,主控储能装置采用恒压恒频控制算法,检测电网电压波动快速补偿有功无功功率;次控储能装置采用恒功率控制算法,维持最大功率的输出。搭建了微电网仿真模型,模拟微电网并网和孤岛运行模式转换的过程,仿真结果验证了该控制策略的有效性。Primary energy in micro-grid such as solar power is easily influenced by natural factors,which lead to the output power unstable.For the above problem,a master-slave control strategy in which storage system was main power of micro-grid was proposed.With technical mature battery as energy storage component,master energy storage adopted constant voltage and frequency control algorithm,which could detect voltage fluctuation and compensate power; secondary energy storage adopted constant power control algorithm,which could ensure to provide micro grid stable power.The simulation model of micro grid was built,and the switch process of interconnection and isolated net was simulated.The simulation proves the validity.
