Fast dynamical reconfiguration algorithm of PV arrays
2014 Ninth International Conference on Ecological Vehicles and Renewable Energies (EVER), 2014In case of mismatch (due to clouds, shadows, dirtiness, manufacturing tolerances, aging, different orientation of parts of the PV field, thermal gradients, etc.), the Power versus Voltage (P-V) characteristic of a PV field may exhibit more than one peak, because of the adoption of bypass diodes, therefore Centralized Maximum Power Point Tracking (CMPPT)

Dynamic and Static Reconfiguration Analysis of Solar PV Array
YMER Digital, 2022Solar photovoltaic (PV) systems are increasingly attractive due to renewable in nature. Solar PV module technologies are paying more attention to enhance the energy production. Partial Shading (PS) will reduce the output power of the PV panel. The PS also causes problems such as mismatch loss and hotspots.

A Rapid Feasibility Checking for Reconfiguration of Mismatched PV Arrays
2019 IEEE 46th Photovoltaic Specialists Conference (PVSC), 2019Power generation efficiency of photovoltaic (PV) arrays is significantly affected by partial shading and PV cell damage. Partial shading or PV cell damage induces mismatched power generation among PV panels and causes an efficiency loss of power generation.

A Reconfigurable PV Array Scheme Integrated Into an Electric Vehicle
Hybrid and Electric Vehicles Conference 2013 (HEVC 2013), 2013This paper outlines an adaptive photovoltaic (PV) array topology and control scheme which has been implemented on a small battery electric vehicle. An array of PV cells is reconfigured in real time via a switching matrix to maintain a close proximity between the array's maximum power point and vehicle DC bus voltage.

A New reconfiguration method for PV array system
IECON 2013 - 39th Annual Conference of the IEEE Industrial Electronics Society, 2013In this study, a method that reconfigures the connection structure of photovoltaic panels has been suggested. It has been applied under partial shading conditions in order to increase the power gained from the photovoltaic array. In the presented method, all submodules of array are formed with the panels that have similar insolation as far as possible.

A Current Supported PV Array Reconfiguration Technique to Mitigate Partial Shading
IEEE Transactions on Sustainable Energy, 2021Partial shading in a solar PV plant is an important concern as it reduces the output power. Dynamic array reconfiguration (DAR) helps in reducing the impact of partial shading. But, it has its own limitations. Further, DAR does not guarantee single peak in array power-voltage characteristics during partial shading.

2015 International Conference on Renewable Energy Research and Applications (ICRERA), 2015
Mismatching operating conditions (due to clouds, shading, non-uniform aging, manufacturing tolerances, etc.) strongly limit the energetic efficiency and the reliability of PV plants. The dynamical re-configuration of PV modules represents a promising solution in order to mitigate the drawbacks associated to mismatching phenomena. The goal of this paper

Embedded reconfiguration of panels to obtain the maximum power of a PV array
2016 IEEE 16th International Conference on Environment and Electrical Engineering (EEEIC), 2016This document presents the reconfiguration of solar panels to improve the power curve from a Photovoltaic array. The proposal consists in an embedded system aimed to reconnect each PV panel and therefore change the properties of the entire array. Simulated waveforms are included for a 2×2 array and the analysis is completed with the experimental ...

Optimal scheme of PV array in partial shading: A reconfiguration algorithm
2016 IEEE International Conference on Mechatronics and Automation, 2016The local shadow can easily make the photovoltaic (PV)array appear hot spot phenomenon, reduce the output power and affects the security and the reliability of the PV power generation system; At the same time, the P-V characteristic of PV array is changed from single peak curve to multi peak curve, which makes the MTTP controller unable to achieve ...
