Study and Performance Analysis of Three Conventional MPPT Algorithms Used in Photovoltaic Applications

Photovoltaic (PV) cell has a nonlinear current/voltage relationship; the output power varies with the variation in weather conditions (Irradiance/temperature). For that, PV systems need special types of control techniques to produce maximum available power. In this paper we aim to numerically study the performance of three type of Maximum Power Point Tracking (MPPT) control algorithms (Fractional short-circuit current (FSCC), Perturb and observe (P& O) and Incremental Conductance (IC)). Implementation and dynamic response of each technique have been discussed. The performance of the used algorithms was evaluated by calculating Relative Error (E), Root Mean Square Error (RMSE) and output power efficiency.
