Abstract:
This paper propose the method of modeling and simulation of photovoltaic (PV) array and achieve maximum power point (MPP) of them. Simulating a photovoltaic array based on the single-diode model has been done in this study. The first objective is to find the parameter of nonlinear I-V equation by adjusting the curve in open circuit, maximum power and short circuit point’s base on the single-diode model and the effect of the series and parallel resistance. The variation of the parameters with change in irradiance and temperature is also studied. Then, equations of the maximum power point of photovoltaic array have been introduced and solved using successive under relaxation (SUR) numerical method. Afterward, disadvantages of SUR method have been identified and fuzzy controller has been used to get the maximum power of the photovoltaic array.
