摘　　要：针对多机电为了保证分布式电源并网后配电网的电压控制在一个合理的水平,同时解决以设备安装容量作为无功上/下限约束可能造成解搜索空间偏大的问题,文中提出一种基于节点补偿容量动态区间法的含分布式电源的配电网无功电压运行优化混合算法。在种群进化后期,引入模拟退火法、罚因子自适应调整机制及动态灾变算法,以改善算法寻优质量及精度。通过算例分析验证了本文算法的高效性及实用性。In order to make reactive power and voltage control in distribution networks at a reasonable leveland solve the problem that the vareompensationupper orlower-limit of equipment capacity may result in larger space of solution search , a hybrid optimization algorithm for reactive power and voltage of distribution networks with distributed genera- tion based on changeablerange of node compensation capacity is presented in this paper. Moreover, a simulated an- nealing, an adaptive adjustment mechanism of penalty factors and a dynamic disaster mechanism are employed in the late period of population evolution, which improves the quality and accuracy of search.The simulation results and anal- ysis demonstrate the efficiency and practicality of the proposed algorithm.
