POWER FACTOR IMPROVEMENT THROUGH TUNING OF CAPACITOR IN RENEWABLE ENERGY SYSTEM

Abstract

The use of renewable energy sources, such photovoltaic (PV) systems, has increased due to rising energy consumption and environmental concerns. However, power factor problems are frequently introduced when PV systems are integrated with the electrical grid, which can lower the grid's overall stability and efficiency. This study investigates ways to raise the power factor in a grid-connected system that has a photovoltaic installation. We examine the difficulties of preserving an ideal power factor when PV generation is present, taking into account changes in solar irradiance and grid circumstances. A hybrid approach to power factor adjustment that combines active and passive compensation techniques is suggested. Inf f order to dynamically modulate the power factor and guarantee optimal energy production from the solar array, the integration of a reactive power controller with the PV inverter system is also investigated. According to simulation results, the suggested method successfully lowers reactive power losses, stabilizes grid voltage, and eliminates harmonic distortion, all of which improve grid performance and energy efficiency. The results emphasize how crucial sophisticated power factor correction methods are to the dependable and long-term integration of renewable energy sources into the electrical grid.
