摘　　要：配电网负荷均衡是降低配电网线损、优化配电网运行的一个目标 ,随着配电网顶点数量的增加 ,可能的负荷组合数量急剧增加 ,基于传统电网模型的优化方法难以实现负荷最优组合。笔者分析了配电网负荷均衡的特点 ,并将该特点与最优化原理相结合 ,采用分层的拓扑模型为手段 ,提出了配电网各源点的负荷最优均衡的原理及原理的实现算法 ,从而将最优问题转为多阶段决策问题 。Loss reduction is important for distribution networks and it is available to reduce loss by loads equalization. With increasing numbers of vertexes in distribution networks, compounding of loads are rapid increasing. It is hard to achieve the global optimization for load balancing by traditional model of distribution networks. Base on analyzing character of loads equalization for distribution networks, this paper provides a new method which conjugate the optimization principle and the hierarchical model of the distribution networks, can transfer the optimization issues into multi stage decision making problems,and can also achieve the optimization equalization of the distribution networks loads.
