摘　　要：为解决高比例分布式电源接入配电网的节点电压波动等问题,提出了一种考虑需求响应的配电网电压有功无功协同优化控制策略。分析了影响节点电压波动的因素,进而说明了可从有功和无功的角度着手对电压进行控制;建立了以配电网有功网损最小、电压总偏差最小以及系统的综合运行成本最小为目标函数的配电网有功无功优化数学模型,并通过权重系数将其转化为单目标模型;通过改进灰狼算法对所建模型进行求解;最后,在IEEE33节点上进行仿真分析,证明了所搭建模型的有效性和实用性。In order to solve the problem of node voltage fluctuation when a high proportion of distributed power is connected to the distribution network,an active power and reactive power cooperative optimal control strategy of distribution network voltage considering demand response is proposed.The factors that affect the voltage fluctuation of node are analyzed,and then the voltage can be controlled from the angle of active power and reactive power.The optimal mathematical model of distribution network active power and reactive power is established,which takes the minimum active power loss,minimum total voltage deviation and minimum comprehensive operating cost of the system as the objective function,and transforms it into a single objective model by weight coefficient.The improved Grey Wolf algorithm is used to solve the model.Finally,simulation analysis is carried out on IEEE33 nodes to prove the effectiveness and practicability of the model.
