Indian researchers have developed a technique-based technique to reduce current losses in PV systems that work under partial shade. They claim that the method increases the energy efficiency and generating income more than conventional reconfiguration techniques.
Researchers from Puducherry Technological University in India have developed a new method to improve the power yield in PV -Arrays that work under partial shade.
With the help of a Sudoku-like technology, the PV system was arranged in a nine by nine solar module configuration to increase the maximum harvested capacity under different shadow patterns. The layout is intended to produce almost equal flows over each row. The pattern follows the logic of a number-based Sudoku puzzle to structure the array.
The four Pyramid Sudoku (FPS) method is designed to evenly distribute the shade over the PV array while retaining electrical connections that supply balanced and maximum current in each row.
The researchers compared FPS with conventional reconfiguration techniques such as TCT, SDK, CMP and CDK under several shadow scenarios. Simulations were carried out using MatLab on a dual-core 2.2 GHz processor with 8 GB RAM.
The research team said that the simulations showed that FPS could reach maximum power more easily than other techniques, which offers both precision and effectiveness.
“Moreover, the FPS approach shows cost-effectiveness by achieving potential annual savings of £ 8,50,267 ($ 9,182),” the scientists said. “This is mainly due to the static reconfiguration mechanism, which eliminates the need for complex switching hardware or dynamic operating systems, reducing the implementation costs and the economic viability of PV systems for solar energy is improved.”
The researchers introduced the approach “The softening of power loss in PV -Arrays using four Pyramid Sudoku under partial shade“Which was recently published in the Ain Shams Engineering Journal.
The researchers intend to include geographical variables in the future. “Geographical institutions influence shade patterns due to buildings, vegetation and topographical characteristics,” they said. “The FPS Her configuration strategy is designed to evenly redistribute the shadow effects, which adjusts adaptability for various environmental conditions.”
