FSO based MPPT Algorithm for Maximizing Power Output in PV System under Partial Shading Conditions

The Power-Voltage characteristics of photovoltaic (PV) systems have multiple peak points under partial shading conditions (PSC). Consequently, to get the most power possible, it is essential to find the global maximum peak point (GMPP). The regular maximum power point tracking (MPPT) algorithms get captured by the local maximum peak point (LMPP) under PSCs. This article introduces an MPPT technique based on the Firebug Swarm optimization (FSO) algorithm for a 9x9 photovoltaic array. A PV system is applied in Matlab/Simulink, and under different irradiance conditions, it is examined, in order to determine the effectiveness of the suggested algorithm with the popular grasshopper optimization algorithm (GOA), grey wolf optimization algorithm (GWO), and particle swarm optimization algorithm (PSO). The simulation outputs prove that the FSO algorithm outperforms GOA, GWO, and PSO in terms of performance characteristics.
