In this article, a modified maximum power trapezium (MPT) method for global maximum power point tracking of photovoltaic (PV) systems under partially shaded conditions (PSCs) is proposed. Compared with the traditional MPT method, the proposed method introduces a variable current range lower bound by utilizing the monotonic output characteristics of the

The PSO Based Global Maximum Power Point Tracker
2019 11th International Conference on Electronics, Computers and Artificial Intelligence (ECAI), 2019The power produced by photovoltaic (PV) module is directly dependent on solar irradiance. The partial shading occurs when PV modules in the PV array have different solar irradiance levels. This can significantly reduce the output power of the PV array.

Hardware methods for detecting global maximum power point in a PV power plant
2015 IEEE International Conference on Industrial Technology (ICIT), 2015Conventional maximum power point tracking (MPPT) algorithms are designed under assumption that all modules are uniformly insulated and therefore can be characterized by a single maximum power point (MPP). At increasing power level PV arrays become larger in area.

Global Maximum Power Point Tracking of Flexible Photovoltaic Modules
IEEE Transactions on Power Electronics, 2014The 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 ...

A Novel Global Maximum Power Point Tracking Method based on Shading Detection
2019 International SoC Design Conference (ISOCC), 2019Partial 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 ...

Experimental evaluation of hardware-based Global Maximum Power Point Searching methods
IECON 2015 - 41st Annual Conference of the IEEE Industrial Electronics Society, 2015Operation under partial shading condition (PSC) significantly decreases energy extracted from photovoltaic (PV) power plants. Non-uniform insolation caused by the passing clouds and natural obstacles results in some PV modules to be effectively excluded from operation.

Global Maximum Power Point Tracking Scheme on a Partially Shaded Photovoltaic Array
IECON 2018 - 44th Annual Conference of the IEEE Industrial Electronics Society, 2018This 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 ...
