High step-up DC-DC Converter based Renewable Energy System for Improving Power Quality and Low Voltage Stress using PI Controller Technique

Abstract

A solar cell turns photon energy into electrical potential in a P-N junction (P-Type and N-Type), which are both equivalent circuits. While synchronizing with various grid and non-linear loads, the PV Photovoltaic input source comprises oscillations distorting, voltage sags/swell, and dc voltage of power quality concerns. The proposed technique for resolving the problem is Grid-connected output-based Photovoltaic (P.V.) System Power Quality Improvement. Proportional Integral (PI) Controllers are used in this method to control parameters like sampling rate and Improved Disrupt and Observe values, which have a substantial impact on the inter oscillatory form property of PV systems. The High gain (Step-Up) DC-DC Converter coupled based capacitor is recovered by the passive clamped circuit, which also limits the switch. Maximum power point tracking is a controller technique that provides inter harmonic emission, which is one of the most significant pieces of enhancing source voltage and current. The end result is improved power quality and gain without even any distortion in the Renewable Energy System's output.
