Abstract: The power leveling (PL) unit is required to maintain a balance of power flow for photovoltaic (PV) system. It is important for it to respond quickly against fluctuation of power generation. A new control scheme based on discrete time system for the PL unit in the distributed generator (DG) is proposed to improve the response. In the proposed method, the deadbeat control is performed using state equations obtained from a combination of two-quadrant chopper and super capacitors. The optimal duty ratio of PWM can be calculated and good performance of the current regulation is obtained. The control theory and the simulation results are presented in this paper.
