An Adaptive Perturb and Observe Algorithm With Enhanced Skipping Feature for Fast Global Maximum Power Point Tracking Under Partial Shading Conditions

IEEE transactions on power electronics, 2023
Solar energy exposed its prominence to diminish the growing energy demands. But the formation of multiple peaks under partial shading conditions causes the conventional maximum power point tracking controllers to fail to track the global maximum power ...

Global Maximum Power Point Tracking in Dynamic Partial Shading Conditions Using Ripple Correlation Control

IEEE transactions on industry applications, 2023
Under partial shading conditions (PSC), a photovoltaic (PV) system may produce multiple local maximum power points (LMPPs). Traditional maximum power point tracking (MPPT) techniques are not able to distinguish between LMPPs and the global maximum power ...

Global Maximum Power Point Tracking of Flexible Photovoltaic Modules

IEEE Transactions on Power Electronics, 2014
The flexible photovoltaic (PV) modules have the advantage of easily fitting on curved surfaces, but in that case their power-voltage characteristic exhibits local maximum power points (MPPs) where the PV module power production is suboptimal. In this paper, the effect of geometrical installation parameters of flexible PV modules, such as the bending ...

Modified grey wolf optimization for global maximum power point tracking under partial shading conditions in photovoltaic system

International journal of circuit theory and applications, 2021
In the study of photovoltaic (PV) system, power‐voltage (P‐V) curves exposed to view several peaks under partial shaded condition (PSC), which brings about muddled and most extreme maximum power point tracking (MPPT) process.

Solar PV Characteristic Independent Fast Global Maximum Power Point Tracking Algorithm

IECON 2020 The 46th Annual Conference of the IEEE Industrial Electronics Society, 2020
This paper proposes a novel maximum power point tracking algorithm for solar PV system that can work even under partial shading conditions. The proposed algorithm is easy to implement, does not depend on any system parameters, and always takes same amount of time for tracking global maximum power point.

A Novel Global Maximum Power Point Tracking Method based on Shading Detection

2019 International SoC Design Conference (ISOCC), 2019
Partial shading conditions (PSC) caused by the nearby trees and dust are inevitable in photovoltaic (PV) generation systems. Traditional maximum power point tracking (MPPT) methods may fail in tracking the global maximum power point (GMPP) under PSC. This paper proposes a novel global maximum power point tracking (GMPPT) method whose tracking speed is ...

Global Maximum Power Point Tracking Scheme on a Partially Shaded Photovoltaic Array

IECON 2018 - 44th Annual Conference of the IEEE Industrial Electronics Society, 2018
This paper proposes an algorithm capable of estimate the global maximum power point of a large photovoltaic (PV) array system operating under partially shaded conditions. The power-voltage characteristic of a photovoltaic array is a nonlinear function that becomes more complex under partial shading conditions, in fact, the power-voltage curve may ...

Global Maximum Power Point Tracking Algorithm for Solar Power System

2019
The P-U curve of the PV (photovoltaic) system has multi-peak characteristics under non-uniform irradiance conditions (NUIC). The conventional MPPT algorithm can only track the local maximum power points, therefore, PV system fails to work at the global optimum, causing serious energy loss.
