Abstract:Aiming at the problem that the output power of photovoltaic power generation is affected by changes in external conditions such as light irradiance and ambient temperature, the author designs a photovoltaic cell output power tracking and control system. First, establish the equivalent circuit model of the photovoltaic cell. Based on this, analyze the power output characteristics of the photovoltaic cell, then design the tracking and control method of the photovoltaic cell output power, and finally verify the correctness and effectiveness of the photovoltaic cell power tracking and control method through simulation .

Keywords: photovoltaic generation; power characteristics; power tracking; power control
