Ellipticity and Deviations from Orthogonality in the Polarization Modes of PSR B0329+54 [PDF]

, 2004
We report on an analysis of the polarization of single pulses of PSR B0329+54 at 328 MHz. We find that the distribution of polarization orientations in the central component diverges strongly from the standard picture of orthogonal polarization modes ...

A robust photovoltaic array reconfiguration strategy based on coyote optimization algorithm for enhancing the extracted power under partial shadow condition

Energy Reports, 2021
The operation of photovoltaic (PV) array under shade faces great challenges due to the power loss that reduces the extracted power. Reconfiguration process is one of the most promising solutions to reduce the effect of shadow on the array.

Minimization of Losses in Solar Photovoltaic Modules by Reconfiguration under Various Patterns of Partial Shading

Energies, 2018
Configurations of photovoltaic (PV) modules, such as series-parallel (SP), bridge-linked (BL), and total cross-tied (TCT) configurations, always utilize a number of connecting switches.

Evaluation of Interconnection Configuration Schemes for PV Modules with Switched-Inductor Converters under Partial Shading Conditions

Energies, 2019
Partial shading on photovoltaic (PV) arrays reduces the overall output power and causes multiple maximas on the output power characteristics. Due to the introduction of multiple maximas, mismatch power losses become apparent among multiple PV modules ...

Optimizing Solar Power Using Array Topology Reconfiguration With Regularized Deep Neural Networks

IEEE Access, 2023
Reconfiguring photovoltaic (PV) array connections among different topologies such as series-parallel, bridge-link, honeycomb, or total-cross-tied is a popular strategy to mitigate impediments in power production caused by partial shading.

Enhancement of power output of partially shaded photovoltaic system using optimal Sudoku puzzle based triple-tied-cross-link reconfiguration techniques

Engineering Research Express, 2023
Partial shade on a photovoltaic (PV) array reduces output power because of mismatch losses. Therefore, selection of PV array configuration is one of the crucial factors to consider for maximum power output. The Triple-Tied-Cross-Link (TTCL) configuration
