L-Shape Propagated Array Configuration With Dynamic Reconfiguration Algorithm for Enhancing Energy Conversion Rate of Partial Shaded Photovoltaic Systems

IEEE Access, 2021
Partial shading is an unavoidable factor that reduces the performance of solar PV systems. The PV system receives uneven irradiation due to partial shading which causes the mismatch loss.

Modelling and analysis of PV configurations (alternate TCT-BL, total cross tied, series, series parallel, bridge linked and honey comb) to extract maximum power under partial shading conditions

CSEE Journal of Power and Energy Systems, 2020
Photovoltaics (PV) are widely used as renewable energy sources for standalone and grid connected PV system. But these PV systems face major reduction in output power and efficiency due to Partial Shading Conditions (PSCs). This research paper focuses on the choice of optimum PV Configuration under a given shading pattern to extract maximum power by ...

Performance of PV array configurations under dynamic partial shadings

EPJ Photovoltaics, 2023
The partial shading effect (PSE) is responsible for most power losses in a photovoltaic (PV) system. By modifying the interconnections between PV modules, called PV array reconfiguration, it is possible to improve the power output under partial shading ...

Performance Enhancement of a Partially Shaded Photovoltaic Array by Optimal Reconfiguration and Current Injection Schemes

Energies, 2021
The output of a photovoltaic array is reduced considerably when PV panels are shaded even partially. The impact of shading causes an appreciable loss in power delivery, since the PV panels are connected in series and parallel to contribute to the ...

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.
