Abstract

Abstract: Photovoltaic Electrical Power Generation System (PV-EPGS) is gaining more importance due to its benefits like no fuel cost, eco-friendliness and less maintenance. However, harnessing the maximum power from large PV-EPGS has become difficult due to the occurrence of a number of peaks in P-V characteristics under partial shaded conditions. This paper presents simulation study of MPPT under partially shaded conditions using the modified version of Particle Swarm Optimization method known as Enhanced Leader Particle Swarm Optimization (EL-PSO). Proposed ELPSO method has advantages over PSO like fast convergence, better dynamic performance, easy implementation and high efficiency. To evaluate the proposed method simulation result of PV panel, Siemens S75 is provided for three different shaded conditions.
