Abstract

The mathematical model of solar photovoltaic power generation system is a typical two-dimensional mathematical model, which can be used in engineering applications. For example, it can be applied to power system, industrial automation design, microelectronics, control and other fields. At present, the mathematical model of photovoltaic power generation system has not been widely studied and applied. Therefore, the simulation calculation can better guide the operation status monitoring and analysis of photovoltaic power generation system. This paper takes photovoltaic power generation system as an example for simulation analysis. In order to verify the correctness and feasibility of the actual model, MPPT simulation program is used to simulate the photovoltaic power generation performance. The test results show that under 0.0001 load cycle, the working characteristics of the progressive conductivity method are basically the same as those of the incremental conductivity method. Under 0.0005 load step, the oscillation occurs at the maximum power point, but the maximum power tracking time is only 0.05 seconds.
