Non-Uniform Aged Modules Reconfiguration for Large-Scale PV Array [PDF]

IEEE Transactions on Device and Materials Reliability, 2017
In the past decades, a large number of photovoltaic (PV) plants have been built. Due to the minor physical differences between PV cells and the influence of environmental factors such as rains, temperature, and humidity, the aging of a PV array is often distributed unevenly within each PV module.

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.

PV array reconfiguration method under partial shading conditions

International Journal of Electrical Power and Energy Systems, 2014
Abstract This paper proposes a new reconfiguration method for photovoltaic arrays under partial shading conditions. With the application the method, the array can produce higher power by reconfigured connections of array. In the proposed method, each row of an array is formed by connecting the panels with close short circuit current levels as ...
