Improvement of Dynamic Models of Photovoltaic Arrays

Abstract:

The nonlinear characteristic of photovoltaic cell following changes of irradiation and ambient temperature must be solved to research solar energy deeply and to utilize it high-efficiently. For building simple and practical dynamic simulation model and seeking after control strategy for raising out-power, a modified dynamic model of photovoltaic array is developed based on the physical model of photovoltaic cell, in which the voltage and current coefficients about ambient temperature and irradiation are introduced. By the model with stronger applicability and generality, the photovoltaic array I-V characteristic can be simulated arbitrarily with changes of irradiationambient temperaturephotovoltaic module parameter and its combination. The validity of the model is verified by all of the simulation results under Matlab/Simulink.
