A PV Array Reconfiguration Algorithm for Minimising Partial Shading Effects [PDF]

2019 10th International Renewable Energy Congress (IREC), 2019
A photovoltaic array is subject to reduction of output caused by partial shading which causes bypass diodes to turn on. This can be alleviated by partly or fully cross-tying the modules within the rows of the array, and reconfiguring the positions of modules within it.

Automatic PV Array Reconfiguration under Partial Shading Conditions

NTU Journal of Renewable Energy, 2023
Photovoltaic (PV) arrays have been recognized as one of the main clean renewable sources of electrical energy. In practice, PV arrays are subject to unavoidable non-uniform partial shading (PS) due to clouds, buildings, dust, etc. PS causes the hot spot problem, mismatch losses, and output power degradation.

Fuzzy Based Reconfiguration Method Using Intelligent Partial Shadow Detection in PV Arrays* [PDF]

International Journal of Computational Intelligence Systems, 2016
Photovoltaic (PV) systems are the most commonly used methods. PV systems have the most potential and efficiency between the species of renewable energy. However, this method can be subjected to a loss of energy gain when shading occurs on the PV panels. To overcome this negative situation, a reconfiguration process in the PV systems has been developed.
