A Fast and Efficient MPPT Technique Based on Voltage Transients for PV Systems Under Partial Shading Conditions

IET Renewable Power Generation, Volume 19, Issue 1, January/December 2025.
In this work, a new MPPT algorithm is proposed that operates by utilizing the transient behavior of the capacitor used at the output of the PV system. The efficiency of the proposed MPPT algorithm varies between 99.92% and 99.21% from PSC1 to PSC6. The average efficiency obtained across all cases is 99.678%. The tracking speed of the proposed algorithm

An MPPT method using phasor particle swarm optimization for PV‐based generation system under varying irradiance conditions

IET Renewable Power Generation, Volume 18, Issue 16, Page 4197-4209, 7 December 2024.
The metaheuristic algorithms are used nowadays eliminating the possibility of getting trapped at the local optima. However, particle swarm optimization (PSO) suffers from delayed convergence, more iterations to reach the optimal point, and random parameter selection.
