Study of PV Module for Characterizations Using MATLAB Simulink and Tracking of Maximum of PV Power

Abstract

Solar energy is the primary renewable energy source, and solar photovoltaic (PV) cells utilise sunlight to generate power for utility applications. The output of PV power varies as a direct current, depending on the intensity of the sunlight. Therefore, understanding the behaviour of PV power in terms of electrical power, voltage, and current is crucial to effectively tracking and extracting the maximum power from the PV system. In this paper, we have configured the parameters of the PV cell using a reference PV module and modelled it within the MATLAB Simulink environment, taking into account changing atmospheric conditions. We successfully simulated the PV characteristics, specifically maximum power, voltage, and current, through a stepwise variation of incoming irradiance and ambient temperatures. The results of these simulations were then compared with data from the actual reference PV cell. The PV model we employed has successfully verified and validated the parameters against the provided actual reference PV module in the MATLAB Simulink environment, yielding results that closely match the actual datasheet specifications.The PV power is  Solar Insolation(S) and ambient temperature(T) dependence. Hence its Maximum power point is to be correctly tracked down. The Maximum power tracking using Perturb and Observe and Fuzzy Logic Based MPPT algorithms have been evaluated and compared.from the result it is seen that Fuzzy Logic MPPT is much better than that of conventional PO.
