摘　　要：为了合理确定节点无功补偿的位置和容量上限,基于遗传算法和弱环状配网特点,通过引入无功补偿分布因子来处理环网,提出一种可动态确定含弱环配网的节点补偿容量上限算法。综合考虑补偿效益和节点电压约束,通过计算补偿净效益最大、节点电压约束两种情况下的节点无功补偿容量上限,有效压缩了遗传算法的寻优空间。通过对IEEE33节点系统算例的分析,验证了算法在含弱环配网无功优化中的实用性。In order to determine the node locations and compensation capacity limits reasonably,based on the features of genetic algorithm and weakly meshed distribution,a method of reactive power compensation distribution factors is proposed to deal with meshed distribution,which can determine the upper limits to node compensation. Both economic benefits and voltage quality are considered,by calculating the upper of node reactive power compensation capacity based on the largest economic benefits and voltage constraint,effectively compresses the search space. The practicality of the proposed algorithm is demonstrated using an IEEE33 test system.
