摘要
Abstract
Inverter control plays a central role in the photovoltaic grid system. This paper poposes a direct pow-er control scheme of grid-connected inverter on the basis of the three-phase photovoltaic grid system. This study measures the voltage and current of the AC side,calculates the instantaneous active and reactive power through coordinate conversion,then compares the results with respectively the reference active power obtained in PI reg-ulator and given reactive power,and finally completes the grid inverter control by a lag ring comparator and switch table links. Matlab/Simulink simulation results show that the grid-connected inverter direct power con-trol method is simple with good dynamic and steady performance,and network power factor is close to 1 with small current harmonics.关键词
