由于分布式电源(Distributed Generation,DG)中存在大量逆变器,加上配电网中已有的非线性负荷,电网中电压和电流质量受到很大的影响,尤其以谐波问题较为突出。提出了一种基于遗传算法和差分进化算法相结合的滤波装置优化配置方法,该方法以滤波装置费用和电能损耗费用之和最小作为优化目标,对含DG的配电网进行有源滤波器和无源滤波器的统一优化配置。所提出配置方法融合了两种算法的优点,将差分进化的思想加入遗传算法,充分利用了父代基因的信息,提高了计算准确度。仿 Due to the large number of inverters in distributed generation (DG), coupled with the non-linear load existing in the distribution network, the voltage and current quality in the power grid are greatly affected, especially in the harmonic problem. This paper presents a method of optimal configuration of filter device based on genetic algorithm and differential evolution algorithm. The method takes the sum of filter device cost and power loss cost as the optimization objective. Passive filter unified optimization configuration. The proposed configuration method combines the advantages of the two algorithms, adds the idea of ​​differential evolution to genetic algorithm, makes full use of the information of the parent gene, and improves the calculation accuracy.
