Abstract
The aim of this paper is to analyze and improve the power quality of island microgrid assuming that the distributed generators could meet the load active power requirement. The main power quality problems through analysis are the harmonics caused by power-electronic devices and voltage variation caused by high reactive power requirement. Based on economy and compensation performance, a combined system constructed by SVC and SAPF is designed to improve the power quality of microgrid in this paper, in which SAPF is adopted near the microsource to mitigate harmonic currents and SVC near the load to compensate reactive power so as to relieve the voltage variation. Simulation results show the effectiveness of the combined system.
