SOLAR ENERGY GENERATION SYSTEM TRACKING ADAPTIVE MAXIMUM POWER POINT AND ITS METHOD

摘要

Provided are a solar energy generation system having an adaptive maximum power point tracking function and a method thereof. The solar energy generation system includes: a minimum maintenance voltage determination unit configured to output a minimum maintenance voltage which enables the inverter to maintain an operation thereof corresponding to a grid voltage of the grid; a maximum power point tracking controller configured to determine a maximum power point tracking voltage at a maximum power point of the photovoltaic module, using the minimum maintenance voltage and an output voltage and output current of the photovoltaic module, and to output a reference voltage to track the maximum power point; a voltage calculator configured to calculate a difference between the reference voltage and the output voltage of the photovoltaic module; and a voltage adjuster configured to generate a reference current value using an output of the voltage calculator.
