摘　　要：以中国内蒙古东部地区即将建成的一个高风电渗透率的微电网为研究对象,依据系统不同运行方式及故障情况下的系统备用容量和损失功率,按照四边界法选取了四种极端情况的算例,深入分析该系统孤立运行时,电网的频率电压特性以及控制策略,为实际孤立电网的安全稳定控制提供参考方案。A micro grid under construction in Eastern Inner Mongolia was studied with high penetration of wind power.According to the spare capacity and power loss under different operation modes and fault conditions,based on the four boundary method,four extreme cases were selected to be simulated,through the simulation results,the response characteristics of system frequency and voltage,as well as the corresponding control strategies could be deeply analyzed,which could be a reference for the security and stability control of actual isolated power grid.
