DC Motor Load performance in DC system with reconfiguration of PV Array [PDF]
Indian Journal of Science and Technology, 2021 Objectives: To examine if the changing of the series-parallel configuration of photovoltaic (PV) array can influence a simple DC drive performance. Methods: In this study, a simulated investigation is carried out for a PV system consisting of 30 panels arranged in 3*5 and 5*3, 3*6 and 6*3, 5*6, and 6*5 configuration. Two motors of rating 5 HP and 10 HP

Electrical PV Array Reconfiguration Strategy for Energy Extraction Improvement in Grid-Connected PV Systems [PDF]
IEEE Transactions on Industrial Electronics, 2009 This paper applies a dynamical electrical array reconfiguration (EAR) strategy on the photovoltaic (PV) generator of a grid-connected PV system based on a plant-oriented configuration, in order to improve its energy production when the operating conditions of the solar panels are different.

A Reconfiguration Method for Extracting Maximum Power from Non-Uniform Aging Solar Panels
Energies, 2018 Aging affects different photovoltaic (PV) modules in a PV array in a non-uniform way, thereby leading to non-uniform working conditions of the PV modules and resulting in variations in the power outputs of the PV array.

An intelligent reconfiguration approach based on fuzzy partitioning in PV arrays
2014 IEEE International Symposium on Innovations in Intelligent Systems and Applications (INISTA) Proceedings, 2014 The reconfiguration process in photovoltaic (PV) arrays is very important to obtain maximum power under partial shading conditions. Connection architecture of array for this process is changed according to status of non-uniform shadows. However, finding of best connection in big PV arrays is hard in real-time.
