A Simulation based driven method to Optimize the efficiency of long Transmission lines using Photo Voltaic Power Generation Technique

This research explores the application of renewable resources, specifically photovoltaic power generation, for efficient long-distance transmission. We are motivated by the pressing need for improved energy transmission in regions like Pakistan and other Asian countries, where abundant oil resources are minimum. These areas currently face significant greenhouse gas emissions from their energy sectors, contributing to rising temperatures. Coal, a carbon-based fossil fuel, dominates the energy production landscape, comprising one-third of total capacity. To address these challenges, we have integrated photovoltaic systems with Ultra-Lift Luo (ULL) Converters to enhance transmission efficiency. DC-DC converters commonly suffer from energy losses, especially due to switching losses during hard switching, significantly diminishing overall system efficiency, To overcome this, we have implemented the Zero Voltage Switching (ZVS) Scheme, ensuring precise device activation near zero crossings, thereby adopting a softer switching approach that substantially improves system efficiency. Following this enhancement, an inverter transforms these stepped-up voltages into AC voltage, which is subsequently transmitted through underground cables to a transformer for distribution. Our research also includes sensitivity analysis, wherein we vary the PV capacity to assess its impact on overall system performance. These experiments have been meticulously simulated using MATLAB/Simulink. Our study aims to optimize the power transmission process, offering promising benefits for the energy landscape in Pakistan and similar regions, thereby promoting sustainable energy solutions.
