Research on Optimal Configuration of the Filter in Distribution Network with Distributed Power

As there are a lot of inverters existed in distributed power coupled with nonlinear loads, the quality of energy power has been greatly affected, especially the harmonic problem. This paper presents an optimal configuration method of the filter based on the combination of genetic algorithm and differential evolution algorithm. The proposed method takes filter investment and energy loss cost as objective function. Then, it combines the advantages of both algorithms for optimizing allocation, numbers and parameters of active filter (APF) and passive filter (PF). Simulations are provided showing the validity of the proposed method.
