Analysis of Different MPPT Techniques Under Partial and Un-shaded Condition for Solar PV System

This paper focuses on the analysis of two different Maximum Power Point Tracking (MPPT) techniques for the solar photovoltaic (PV) system under partial shaded and un-shaded condition. Perturb & Observe (P&O) and Particle Swarm optimization (PSO) method of MPPT tracking have been incorporated in the solar PV system and the results have been compared among each other. The main aim of this paper to apply the MPPT technique which can track global maxima and not the local maxima under the partial shaded condition of the PV module. The above two MPPT techniques have been tested under partial shaded condition and uniformly shaded condition of PV module. The test system is modeled and simulated using MATLAB/Simulink.
