Experimental evaluations of global maximum power point tracking approaches in partial shading conditions

2017 IEEE International Conference on Environment and Electrical Engineering and 2017 IEEE Industrial and Commercial Power Systems Europe (EEEIC / I&CPS Europe), 2017
Maximum power point tracking (MPPT) under partial shading conditions (PSC) has been popular topic recently. In this paper, P&O algorithm, full scanning and large scanning methods and a novel method are evaluated experimentally. In order to compare the methods and algorithms considered, a single ended primary inductance converter (SEPIC) was set up ...

Global Hybrid Maximum Power Point Tracking for PV Modules Based on a Double-Diode Model

IEEE Access, 2021
Photovoltaic systems under partial shading conditions (PSC) need to operate at the global maximum power point (GMPP) to extract the maximum possible power. Partial shading is characterized by the exhibition of a multi-peaked behavior in the voltage power

Global maximum power point tracking in partially shaded PV systems using plant reproduction algorithm

IET Renewable Power Generation, 2021
The power–voltage curve of photovoltaic (PV) power generation system under partial shading conditions (PSC) is non‐monotonic with multiple power peaks and traditional methods do not guarantee global convergence which leads to energy loss.

An Improved Global Maximum Power Point Tracking Scheme under Partial Shading Conditions [PDF]

Journal of international Conference on Electrical Machines and Systems, 2013
A photovoltaic array exhibits several local and single global maximum power points under partial shading conditions. To track the global maximum power point precisely, a novel global maximum power point tracking scheme is proposed in this paper. In the proposed scheme, robustness of the tracking performance has been improved by enhancing searching ...

Module Level Global Maximum Power Point Tracking Strategy

2019 4th International Conference on Power Electronics and their Applications (ICPEA), 2019
Partial shading of photovoltaic (PV) modules can occur at any time due to the obstacles such as chimney, tree, antenna, bird flock etc. Due to such obstacles, the entire surface of the PV module cannot receive an equal amount of irradiance; Therefore, PV modules cannot operate at its maximum power point (MPP).
