Mathematical model of total cross-tied photovoltaic arrays in mismatching conditions
2012 IEEE 4th Colombian Workshop on Circuits and Systems (CWCAS), 2012 This paper presents a mathematical procedure for modeling rectangular (N rows with M modules each) and non-rectangular photovoltaic (PV) arrays in Total Cross-Tied (TCT) configuration operating in uniform and mismatching conditions. The proposed model uses the simple single diode representation for each PV module; then each row of the TCT array is ...

Mathematical model to estimate the maximum power output of a total cross tied connected PV array during partial shading condition [PDF]
IET Renewable Power Generation, 2019 Estimation of the output power of a solar photovoltaic (PV) system during partial shading condition (PSC) is an interest of PV installers. Owing to the inclusion of a bypass diode, the occurrence of local and global maximum peak creates more difficulty in the calculation of maximum power output from a PV array.

IET Renewable Power Generation, 2020 Shade phenomena affect the PV module's power output, introduce multiple peak points in PV characteristics, and shorten the expected life cycle of the module. In order to prevent this issue, PV modules should reconfigure, namely, altering the electrical connections between PV modules based on the irradiance without changing their physical locations.
