Optimal SuDoKu Reconfiguration Technique for Total-Cross-Tied PV Array to Increase Power Output Under Non-Uniform Irradiance

IEEE Transactions on Energy Conversion, 2019
Partial shading condition drastically reduces the maximum power output of photovoltaic array. Partial shading occurs due to several factors, such as flying birds, trees, and passing clouds. Many ways can be mitigated partial shading problems in photovoltaic (PV) array.

Improved SuDoKu reconfiguration technique for total-cross-tied PV array to enhance maximum power under partial shading conditions

Renewable and Sustainable Energy Reviews, 2019
Abstract Mismatch losses ignore the performance of individual photovoltaic (PV) modules and cut back most of the power from the PV array. These losses mainly due to partial shading condition (PSC), are caused by the reduction of spacing between PV modules, passing clouds, and near buildings, etc.

Total Cross Tied-Inverted Triangle View Configuration for PV System Power Enhancement

Intelligent Automation & Soft Computing, 2022
Electricity can be generated from a photovoltaic cell depending on the amount of solar radiation received from the solar system. But due to some factors such as partial shade conditions, as the thickness of the shade increases, the peak power output from

PV Distributed-MPP Tracking: Total-Cross-Tied configuration of MICs to extract the Maximum Power under Partial Shading conditions

2018 IEEE International Conference on Power Electronics, Drives and Energy Systems (PEDES), 2018
The Photovoltaic (PV) central inverter architecture comprises of various PV module configurations. The PV module configurations are vulnerable to shading effects and cause mismatching power losses. To reduce the detrimental effect of shading and mismatching on energy production, Distributed-Maximum Power Point Tracking (D-MPPT) architecture has been ...

Effects of shading on current, voltage and power output of total cross-tied photovoltaic array configuration

TENCON 2015 - 2015 IEEE Region 10 Conference, 2015
The Philippines, being a tropical country, has a high photovoltaic (PV) energy generation potential that can help meet demand due to impending power supply shortage in the coming years. One factor that limits solar PV generation is nonuniform illumination or partial shading.

Experimental investigation of serial parallel and total-cross-tied configuration photovoltaic under partial shading conditions

2017 International Conference on Sustainable Energy Engineering and Application (ICSEEA), 2017
One of issues about array photovoltaic (PV) is partial shading conditions. It can cause mismatch between the modules, leading to undesirable effects such as reduction in power generated and hot spots. Partial shading is caused by passing clouds, tree shadows, nearby building, tower, poles, etc. So the power output is less than expected value. It is not

A Su Do Ku puzzle based shade dispersion for maximum power enhancement of partially shaded hybrid bridge-link-total-cross-tied PV array

Solar Energy, 2020
Abstract Partial shading of photovoltaic (PV) arrays results in hot spot creation and multiple peaks in the power-voltage (P-V) characteristics which ultimately leads to mismatch power loss in the PV system. This loss is a function of the shading pattern and configuration of the PV array.

Su-Do-Ku and symmetric matrix puzzles–based optimal connections of photovoltaic modules in partially shaded total cross-tied array configuration for efficient performance

Distributed Energy Resources in Microgrids, 2019
Solar photovoltaic (SPV) systems can be used to harvest the energy of sunlight in the form of direct current, but even a slight objection to the direct sunlight via any static or dynamic obstacle amidst the two can cause the condition of partial shading ...
