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.

Superstrate-based patch antenna array with reduced in-band radar cross section

, 2021
To design a low radar cross section (RCS) antenna, the major concern is not only to reduce scattering, but also to maintain its radiation parameters, viz. gain, voltage standing wave ratio (VSWR), etc.

Optimal Hybrid PV Array Topologies to Maximize the Power Output by Reducing the Effect of Non-Uniform Operating Conditions

, 2021
The photovoltaic (PV) system center inverter architecture comprises various conventional array topologies such as simple-series (S-S), parallel (P), series-parallel (S-P), total-cross-tied (T-C-T), bridge-linked (B-L), and honey-comb (H-C).

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.

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 ...

An Approach to improve the Performance of Total Cross-tied connected PV array in Partial shading condition

, 2020
Due to the partial shading condition (PSC) in solar PV systems, performance degrades to a large extent. To overcome from this problem bypass diode is used which creates the problem of multiple local maxima.
