摘　　要：首先基于典型的辐射状配电网结构,推导基于电压灵敏度的配电网电压-有功解析表达式。在此基础上,提出一种基于电压灵敏度矩阵的分布式光伏有功和无功协同控制方法。仿真结果表明,所提出的电压控制方法能有效解决配电网电压越限问题,能充分利用分布式光伏的无功输出能力,同时使同一条馈线上的所有分布式光伏均分有功功率削减量,共同承担因参与电压调节带来的发电量损失。Based on the typical radial distribution network structure,the paper firstly deduces the voltage-active expression of the distribution network based on the voltage sensitivity,based on which,a distributed PV active and reactive power coordination control method based on the voltage sensitivity matrix is proposed.Simulation results show that the proposed voltage control method can effectively solve the voltage crossing problem of the distribution network,fully utilize the reactive power output capability of distributed PV,and at the same time,make all distributed PV on the same feeder share the active power reduction and share the power generation loss caused by the participation in voltage regulation.
