摘　　要：分布式电源的选址和定容会对配电网规划产生很大影响,利用Weibull风速概率分布建立了分布式电源的数学模型,并采用基于隐式编码方式与最优保存策略的遗传算法,对IEEE14节点配电测试系统进行仿真,得到了分布式电源选址和定容的最优规划方案。算例结果表明,分布式电源的接入有效提高了系统的经济性,利用所提算法进行不同渗透率下的分析,为实际含分布式电源的配电网规划提供了一种简化思路。The locating and sizing of distributed generation(DG)have a significant impact on the distribution network planning.This paper used Weibull wind speed probability distribution to establish a mathematical model for DG and adopted the genetic algorithm based on the implicit coding scheme and elitist strategy to carry out simulation of IEEE14nodes distribution test system,obtaining the optimal planning scheme of locating and sizing of DG.The calculation example shows that the DG access effectively improves the economy of the system.The mentioned algorithm was used to analyze the different permeability to provide a kind of simplified thought for the distribution network planning with DG.
