Improved Circuit Model of Photovoltaic Array
نویسنده
چکیده
A circuit based model of photovoltaic array (PV) suitable for simulation studies of solar power systems is proposed in this paper. The proposed model is realised using Power System Block Set under MATLAB/SIMULINK, however, it can be constructed using standard simulation software such as PSPICE. The proposed circuit model has several advantages: simple, reliable, allows simulation of basic cells, group of cells, or mismatched panels that work under different operating conditions. The obtained results of both uniform and mismatched PVs prove the validity of the proposed model to simulate the non-linear behaviour of photovoltaic array not only to understand the operation of PV systems but also to design a proper maximum power point tracker to extract the maximum possible power from the photovoltaic array. Keywords—Photovoltaic array, piecewise linear model, modelling, simulation.
