Moreover, in most circuit simulators, parameters of the PV source electrical circuit model refer to the circuit elements ( I ph, R s, R sh and I d of the diode). where only two parameters (Iph and Id) are considered as function of the solar irradiance and cell temperature by using two controlled current sources.
A novel equivalent circuit-based model for PV sources has been proposed. It is easily implementable in circuit-oriented simulators platforms such as PSpice, PSCAD/EMTDC, PSIM, MATLAB/Simulink, Saber, etc., which are commonly used to simulate power systems, power electronics devices dedicated to PV applications.
Conventional equivalent circuits composed of resistances and parallel diodes cannot well reflect this behavior of discrepancies, especially when the device exhibits a strong S-type character, so that, given the same set of parameters, the dark and light I - V curves have the same shape, which does not accurately meet the experimental results.
