摘要(Abstract):
目前,智能配电网得到了快速发展,自愈作为其主要特征具有重要的研究意义,但迄今尚未有全面的智能配电网自愈能力衡量标准。建立了智能配电网故障后自愈能力评估指标体系,提出了自愈能力评估方法。针对自愈能力评估指标,建立了自愈恢复率、自愈恢复速度、自愈控制操作复杂度、自愈可持续时间覆盖率等4项量化指标,涵盖了配电网故障后负荷恢复的范围、速度、操作难度、可持续时间等因素。然后,基于负荷与分布式电源(distributed generation,DG)出力的时序数据,通过故障遍历的方式,对配电网各区段故障后的自愈能力进行了评估计算,并将各区段故障概率作为权重计算得到了全系统自愈能力水平。最后,基于构建的含10个区段的配电系统进行仿真分析,考虑了不同故障时间、不同故障区段、不同DG渗透率等对系统自愈能力的影响,并进行了时空分析,得到了系统自愈的薄弱区段和时段,验证了所提评估指标和评估方法的有效性。
