摘　　要：利用PSCAD建模,研究了微网从并网向孤网模式转换的动态运行特性,获取了微网电压与频率的变化规律.微网由各分布式电源提供功率支撑,由IEEE34节点配网提供电压支撑.由于微型燃气轮机的慢响应特性,微网在过渡过程中引起频率电压波动极大,不利于系统稳定运行,储能设备对于微网稳定有重要作用,采用下垂控制策略的蓄电池作为储能设备,有效抑制了由微型燃气轮机所引起的电压和频率误差.The dynamical characteristics of a micro grid from grid-connected mode to island mode are analyzed by using PSCAD. The changing laws of voltage and frequency of micro grid are obtained. DGs are used as the main power support,and IEEE 34 node mode is used as the main voltage support. Because of the slow dynamic response of micro turbine, the voltage and frequency fluctuations caused are not beneficial to stable operation of the micro grid. Storage devices plays an important role in micro grid control and battery using droop control of could damp the voltage and frequency error caused by micro turbine.
