Abstract

Abstract Due to the obvious steady-state error that traditional grid-connected pre-synchronization regulation, current shock may occur when photovoltaic micro-grid is connected to the grid. To solve this problem, an improved pre-synchronization method with higher steady-state adjustment accuracy is designed by using the brain emotion control algorithm in the inverter control link. This method can reduces the transient shock of current when the micro-grid is connected to the grid. MATLAB / Simulink software is used to establish a simulation model, through which the correctness and feasibility of the proposed method are verified.
