Volume fourth, phase twenty-fifth, April 2009 electric Power section learn and work Cheng Vol.25, No.4, Apr., 200911 Electric, Power, Science, and, Engineering General mathematical model of photovoltaic cells based on MATLAB Chang Jiang Wang (Institute of electrical and electronic engineering North China Electric Power University Beijing 102206) Abstract: according to the output characteristics of photovoltaic cells is non-linear, according to DC physical model of solar cell, using MATLAB to build the simulation model of general solar photovoltaic array. The model is used to simulate the arbitrary environment, the solar radiation intensity, the parameters of the panel, and the I-V characteristics of the PV array in series parallel connection. The internal parameters of the model are optimized to better reflect the actual characteristics of the battery. The model has the maximum power point tracking function, and can achieve the best tracking point of the photovoltaic power generation system. Key words: photovoltaic cells; MPPT; I-V characteristics; CLC number: TM615; document identification code: A Zero lead word One Photovoltaic cell characteristics With the consumption of fossil energy, the whole world is facing the energy crisis, and solar energy has become the second largest energy [1] by its clean, wide distribution and so on. Photovoltaic array series parallel package composed of a plurality of single solar cell is formed, energy supply center of photovoltaic power generation, the I V curve with the intensity of sunlight and solar cell temperature change, namely I=f (V, S, T). At present, while the manufacturers usually only provide users with standard test I SC short-circuit current, open circuit voltage of Voc, the maximum power point current I m, maximum power voltage V m value, s
