Novel Shade Dispersion Method To Extract Maximum Power under Partial Shading Condition

IECON 2021 – 47th Annual Conference of the IEEE Industrial Electronics Society, 2021
Partial shading condition (PSC) is a critical factor affecting the performance of PV array in terms of mismatch losses and power loses. To alleviate it, various conventional and hybrid PV array topologies has suggested in the literature. It concentrates the shade on the influenced area.

Partial Shading Mitigation in Photovoltaic Arrays using Shade Dispenser Technique

2019 IEEE 10th International Symposium on Power Electronics for Distributed Generation Systems (PEDG), 2019
Partial Shading (PS) critically reduces the maximum power extractable from a photovoltaic (PV) array, decreasing its efficiency, and creating multiple local peaks (LP) in the characteristic P-V curve of the array. Currently, the electrical interconnection that minimizes these losses is the Total Cross Tied (TCT), where each panel in a string is ...

Performance of partially shaded photovoltaic array configurations under shade dispersion

2014 International Conference on Advances in Green Energy (ICAGE), 2014
Photovoltaic (PV) arrays which are prone to partial shading lessen the energy output of PV systems and the arrays exhibit multiple peaks in the Power-Voltage (P-V) characteristics. This paper investigates the performance of various photovoltaic array configurations under shade dispersion to improve the generated power from the array, under partial ...

50 shades of partial information

2015 IEEE International Conference on Grey Systems and Intelligent Services (GSIS), 2015
Since their origins in the 1980's, grey systems thinking and grey numbers have found a wide and growing range of applications. One of these is in providing decision support for multi-criteria choice. All the key elements of multi-criteria modelling are potentially infused with a lack of certainty: weights on criteria, performance levels of alternatives,

Shade diffusion of partial shaded PV array by using odd-even structure

Solar Energy, 2019
Abstract This paper proposes an improved permanent structuring technique to configure the panels in photo voltaic (PV) array so that optimum power output can be achieved under partial shading conditions. The proposed technique enables the structure to redistribute shading effect on complete PV array by using panel physical positions alternatively ...
