摘要(Abstract)：

随着大规模的分布式电源(distributed generation,DG)接入及电网与用户互动增加,主动配电网状态估计结果与量测配置需要考虑更多不确定性因素。为加强对配电网的实时监测与控制,提高配电网运行态势感知能力,需要发展同步相量测量装置(phasor measurement unit,PMU)。在计及DG与负荷不确定性的基础上,建立了考虑经济性、配电网状态估计精度以及节点电压越限概率的多目标PMU最优配置模型。以拟蒙特卡洛方法模拟DG与负荷的不确定性;基于两步式加权最小二乘方法,构建混合量测配电网状态估计模型,并利用改进的自适应多目标二进制差分进化算法进行求解,从而得到特定状态估计误差精度下的PMU最优配置Pareto非劣解集。通过IEEE 33节点配电网系统进行仿真计算分析,验证了所提模型与算法的可行性与有效性。
