Modeling and performance analysis of novel quad‐tied PV array configuration under partial shading conditions

Energy Science & Engineering, 2023
A photovoltaic (PV) cell is the smallest unit in an array that exhibits nonlinear characteristic curves. To gather the maximum amount of energy from a PV array under partial shading conditions (PSCs), it is necessary to follow the largest peak in the ...

Enhanced power generation for total‐cross‐tied PV array using simulated annealing under partial shading conditions

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.

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.

Effect of partial shading patterns and degrees of shading on Total Cross-Tied (TCT) photovoltaic array configuration

Energy Procedia, 2018
Abstract Effect of partial shading on PV modules is simulated. Three standard configurations of PV array consisting of series-parallel (SP), bridge-linked (BL), and total cross-tied (TCT) are studied. Nine PV panels are arranged in 3x3 array. The suitable solar radiation level to start reconfiguring the PV array according to shading pattern is ...

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 ...

A Novel Benzene Structured Array Configuration for Harnessing Maximum Power From PV Array Under Partial Shading Condition With Reduced Number of Cross Ties

IEEE Access, 2022
Partial shading (PS) phenomena significantly degrade the power output from the photovoltaic (PV) array. Due to the PS effect, there is a mismatch in current between the PV modules of a series-connected PV string.

A Static Kropki Puzzle Pattern‐Based Shade Dispersion Technique for a Partially Shaded Photovoltaic Array

Energy Science & Engineering
Partial shading is crucial in reducing the performance of the photovoltaic (PV) array. The static reconfiguration is a viable option for alleviating the partial shading. The scattering of shade relies on its puzzle pattern.
