Abstract

This paper uses a simplified mathematical model of engineering panels to accurately simulate the output characteristic of the solar cells only to know individual panels’ parameters. On photovoltaic characteristic curve fitting timeliness, the four broken-line method combined with linear interpolation and parabolic interpolation is adopted to accurately simulate the output characteristics of photovoltaic battery. Based on this method, the main circuits to Buck circuit and control section which use the current closed-loop PI control are introduced. The simulation results show that using the four broken line method to piecewise fit photovoltaic battery output characteristics having a high precision. Finally, according to the nonlinear output use the MPPT control the photovoltaic battery simulator and the simulation results show the control precision.
