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 ...

A Global Maximum Power Point Tracking Algorithm for Photovoltaic Systems Under Partially Shaded Conditions Using Modified Maximum Power Trapezium Method

IEEE Transactions on Industrial Electronics, 2021
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

A global maximum power point tracking method for PV module integrated converters

2012 IEEE Energy Conversion Congress and Exposition (ECCE), 2012
This paper proposes a maximum power point tracking (MPPT) method to seek the global maximum power point (MPP) in photovoltaic (PV) modules. The method infers partial shading—and hence the possibility of multiple maxima—by monitoring bypass-diode voltages and initiates a global search routine only if a bypass diode turns on.

Experimental evaluation of global maximum power point techniques under partial shading conditions

Solar Energy, 2020
Abstract Shading plays an important role in the operation of photovoltaic (PV) systems, especially when one of the cells or modules in the string is submitted to lower irradiance levels due to partial shading (PS). As a result of this condition, the cells or modules absorb the power generated by the unshaded parts, thus causing hot spots that can ...

Dragonfly Algorithm Based Global Maximum Power Point Tracker for Photovoltaic Systems

2016
This paper presents the application of the Dragonfly Algorithm (DA) for tracking the Global Maximum Power Point (GMPP) of a photovoltaic (PV) system. Optimization techniques employed for GMPP tracking (GMPPT) are required to be fast and efficient in order to reduce the tracking time and energy loss respectively. The DA, being a meta-heuristic algorithm

On-line global maximum power point (GMPP) identification of solar PV plants

2018 IEEE Applied Power Electronics Conference and Exposition (APEC), 2018
This paper introduces an algorithm to identify the global maximum power point (GMPP) of a solar Photovoltaic (PV) plant while operating under the partial shade condition (PSC) or fault condition (FC). Conventionally a complete current vs. voltage (or I-V) curve of the faulty PV array is swept to identify the GMPP.
