Research on the Method of Using APF to Improve the Power Quality of Microgrid Based on the Control of Energy Storage

摘要

Based on hybrid energy storage control, use the parallel active filter APF to improve microgrid power quality, the parallel active filter control methods based on proportional resonance, through the energy storage system with active filter to improve power quality indexes, such as, voltage harmonic and current harmonic. The simulation results show that the method is correct when the load of microgrid is nonlinear. The simulation results prove that the control method is correct.
