摘　　要：针对风电和光伏接入配电网会加剧电网的电压波动和网络损耗,提出了考虑新能源无功功率输出的配电网无功补偿优化策略。首先分析了风光无功的输出特性;然后建立以电网电压偏差和有功网损最小作为目标的配电网无功优化模型;最后,提出改进的NSGA-Ⅲ算法求解无功优化调度方案,在改进后的IEEE 33节点配电系统进行算例分析。结果表明:所提多目标无功优化模型和NSGA-Ⅲ优化算法能够有效提高系统节点电压质量和稳定运行水平。Aiming at the exacerbation of voltage fluctuations and network losses caused by the integration of wind and photovoltaic power into the distribution network,a reactive power compensation optimization strategy considering the output of new energy reactive power in the distribution network was proposed.Firstly,the output characteristics of wind and solar reactive power were analyzed;then,a reactive power optimization model was established for the distribution network with the goal of minimizing grid voltage deviation and active power loss;finally,an improved NSGA-Ⅲalgorithm was put forward to solve the reactive power optimization scheduling scheme,and a case study was conducted on the improved IEEE 33 node distribution system.The results indicate that the proposed multi-objective reactive power optimization model and NSGA-Ⅲoptimization algorithm can effectively improve the voltage quality and stable operation level of system nodes.
