Rapid and Efficient MPPT Technique with Competency of High Accurate Power Tracking for PV System

Partial shading condition (PSC) is the most serious concern of a photovoltaic (PV) system as it pointedly decreases the proficiency of PV system. The PV system generates numerous peaks in its output power characteristics curve under PSC. To track a global maximum power point (GMPP) with-in a suitable time limit, a consistent method is thus required. For achieving high performance, enhanced convergence and less power fluctuations during cloudy sky, conventional PSO is altered. The main objective of this paper is to identify the maximum power point (MPP) by utilizing an improved particle swarm optimization (IPSO) under PSC. To authenticate the proficiency of the proposed algorithm under diverse PSC, analysis between two commonly employed conventional PSO and Improved PSO MPPT techniques is made through theoretical analysis and digital simulation by using Matlab/Simulink. The obtained simulation result shows the fast tracking speed, extraordinary consistency and high exactness in tracing the GMPP.
