POWER QUALITY ASSESSMENT OF CPUC-BASED SOALR PHOTOVOLTAIC SYSTEM WITH NLMS FOR GRID – TIED APPLICATIONS

Abstract

The adverse environmental impacts of fossil fuel consumption, along with their limited availability, have driven many countries to explore and adopt renewable and eco-friendly energy alternatives to meet the growing demand for electricity. Among various renewable sources such as wind, solar, geothermal, and biomass, solar and wind energy have emerged as the most promising and widely utilized technologies. Solar and wind energy sources are inherently complementary, making their integration highly effective for reliable power generation. A hybrid photovoltaic (PV) and wind energy system offers improved dependability by ensuring a continuous power supply, either independently or in combination, to meet load requirements. In solar PV systems, Maximum Power Point Tracking (MPPT) techniques are employed to maximize energy extraction, while in wind energy systems, a Permanent Magnet Synchronous Generator (PMSG) driven by a wind turbine operates efficiently, often with a fixed pitch angle. This paper presents the architecture, modeling, and simulation of a hybrid solar PV and wind energy system. The combined system is simulated using MATLAB/Simulink to evaluate its performance. The simulation results demonstrate the effectiveness of integrating solar and wind energy sources, highlighting their potential to provide a stable, efficient, and sustainable power supply.
