Abstract: In order to research on the problem of photovoltaic system tracking maximum power taking lithium battery as the energy storage element, this paper proposed a kind of lithium battery modeling approach based on experimental test. It was a simple model whose power supply, capacitance, resistance and etc parameters were highly fitting for experimental data. The flexible amorphous silicon photovoltaic power generation system using Matlab Simulink, which connected with the lithium battery, realizes the maximum power point tracking control function, which verifies the validity of the model.
Key words: flexible amorphous silicon photovoltaic power generation system; lithium battery; equivalent circuit model; maximum power point tracking
