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 ...

Global Maximum Power Point Tracking Algorithm for Solar Power System
2019The 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.

A High Speed Global Maximum Power Point Tracking Algorithm for PV Systems
2016Partial shading is one of the unfavourable conditions for photovoltaic modules since available power of them decreases. Besides that, maximum power point tracking becomes difficult in that kind of condition. Multiple maximum power points occur on the voltage - power curve of photovoltaic modules, if modules have bypass diodes.
