摘要(Abstract)：

随着大规模分布式光伏系统并入配电网,配网渗透率不断提高。光伏出力与负荷的不平衡导致线路中出现逆向潮流,引起电压越限。采用蒙特卡洛随机法模拟配网大规模光伏接入的情景,从单渗透率和整体两方面对模拟结果全面分析以充分评估配电网的光伏消纳能力;提出利用光伏系统逆变器的控制措施缓解并网节点的电压越限问题,进而提升配电网光伏消纳能力,通过计算电压灵敏度矩阵为所有并网逆变器分配无功补偿量,辅以有功缩减改善光伏并网特性。通过Matlab搭建IEEE33节点系统,仿真结果表明所述方法的有效性和可行性。

关键词(KeyWords)： 分布式光伏;光伏消纳;电压灵敏度;无功补偿;有功缩减
