A Novel Global Maximum Power Point Tracking Scheme Under Partially Shaded Conditions
2013Under partially shaded conditions (PSCs), multiple peaks appear on the power-voltage curve of the photovoltaic (PV) array, which makes it difficult to track the global maximum power point. To address this issue, we first analyze the nonlinear characteristic of PV array under PSCs.

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 ...

Neural network based global maximum power point tracking under partially shaded conditions
2015 23rd Iranian Conference on Electrical Engineering, 2015Partial shading changes characteristics of a solar panel and creates a number of local maximum power points (MPPs) that only one of them is the global MPP. On the other hand measurement of light intensity is quite hard and requires use of specialized sensors.

Experimental implementation of an electronic load for global maximum power point tracking
2016 IEEE 2nd Annual Southern Power Electronics Conference (SPEC), 2016This work deals with the partial shading effect in the power curve of a PV solar array. Using a semiconductor device — MOSFET or IGBT — as electronic load added to a buck converter, it is possible to scan the power curve of a photovoltaic string and therefore empirically determine its optimum voltage, even in presence of partial shading.

Maximum Power Point Tracking (MPPT) is a technique employed to extract maximum power available from a photovoltaic (PV) module under varying atmospheric conditions. It traces the PV operating voltage corresponding to the maximum power point (MPP) and operates the panel at MPP. However, if a PV array is partially shaded, the conventional MPPT techniques

2017 19th European Conference on Power Electronics and Applications (EPE'17 ECCE Europe), 2017
In this work, an Analog Global Maximum Power Point Tracker (A-GMPPT) is introduced and discussed. The underlying idea of this A-GMPPT is the peak power tracking using a capacitive load, in particular the filter input capacitance of the DC/DC converter.

Global maximum power point tracking based on new extremum seeking control scheme
Progress in Photovoltaics: Research and Applications, 2015AbstractA new perturbed‐based extremum seeking control (PESC) scheme is proposed in this paper to track the global maximum power point (GMPP). The PESC scheme has two control loops based on power of the photovoltaic (PV) array: the first loop operates as usually to track the maximum power point and the second sweeps all local MPPs to locate the GMPP ...
