Extraction of the Global Maximum Power for PV System under PSC Using an Improved PSO Technique

, 2023
To get the most power out of photovoltaic (PV) panels, PV systems must utilize a maximum power point tracking (MPPT) controller. In partial shading conditions (PSC), the power-voltage (P-V) characteristic of the PV network may show a single global ...

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.

An improved regression‐based perturb and observation global maximum power point tracker methods

IET Renewable Power Generation, Volume 18, Issue 9-10, Page 1646-1660, 17 July 2024.
This paper proposes a regression‐based perturbation and observation method to quickly find a global maximum power point tracker, avoiding being stuck in local maxima, likewise analytical and metaheuristic methods. Linear and non‐linear regression analyses narrow the search area using generated photovoltaic model on a flexible Python environment ...
