Distribution Optimization of DGs in Distribution Networks Based on Hierarchical Partitioning Model

在含分布式电源的配网规化中,分布式电源模型的建立、潮流计算方法的选择和优化算法的运用,对优化结果至关重要。在配网分布式电源三类传统模型基础上,为便于计算支路电流,对含分布式电源的支路引入新模型——分层分区DG模型;基于新模型,分析了各种潮流算法,结合含分布式电源的配网特点,改良了推回代潮流计算;最后通过微分进化算法,以网损最小为目标,对计算结果进行优化,得出配网电源的最优位置和容量。

It is of vital importance to establish the models of distributed generators（DGs）,choose the power flow calculation method and optimize the algorithm for optimizing distribution of DGs in distribution network.The paper firstly introduces the new models of branches with distributed power supply.Then taking the minimization of the losses as the objective,it explores the optimal location and capacity of DGs in the network planning by using the back/forward sweep method and differential evolution algorithm.
