基于配电网谐波责任划分的分布式有源滤波系统
Distributed Active Filtering System Based on Capacity Allocation of Harmonic Compensation
摘要
Abstract
With the extensive application of power electronic devices and the access to distributed energy,the power quality problem of low-voltage distribution network is becoming more and more serious.In order to improve the power quality at the point of common coupling (PCC) in the low-voltage distribution network with multiple harmonic feeders,a distributed active power filter system is created.By estimating the contribution of each harmonic feeder to the voltage harmonic distortion on PCC,the harmonic compensation duty of each feeder is optimized.Furthermore,by adopting the virtual harmonic impedance based droop control,autonomous coordination between multi-function devices is achieved,and an optimization algorithm for the capacity allocation of the harmonic compensation is proposed with reference to the harmonic contribution.In the end,the effectiveness of the proposed model is verified by simulation results.关键词
