Abstract
The photovoltaic MPPT system structure and working principleare analyzed. Variable step voltage perturbation method is used asthe power/voltage optimization controller. In order to achieve fast and stable PV MPPT response,this paper focuses on theoptimized design of the voltage-loopofPV output voltage controller.Thevoltage feed-forward compensationplus PI regulator methodis used to design a compositevoltage controller of PV MPPT. Voltage closed-loop transfer function is obtained through the establishment of the PV output voltage controller mathematical model. To get fast and stable MPPT control, the best PI controller parameters are calculated.The simulation results and experimental results indicate that this compound controllerof voltage can quickly achieve a stable photovoltaic MPPT response.关键词
