Power Quality Improvement using ASO Technique

Hybrid Renewable Energy Sources (HRES) combined with grid connection is becoming more important in meeting the massive demand for electrical power in the present environment. This integration reduces the use of fossil fuels even more, as well as environmental difficulties. In grid-connected systems, HRES such as photovoltaic (PV) systems, wind turbines (WT), and battery energy storage systems (BESS) are producing power quality issues (PQ). To address such challenges in the HRES system, Atom Search Optimization (ASO) in conjunction with a Unified Power Flow Controller (UPQC) is suggested. UPQC is one of many specialized power devices that are utilized to successfully minimize PQ concerns such as voltage/current sag, swell, and Total Harmonic Distortions. The fractional order PID controller is intended to drive a UPQC using control parameters developed using the ASO approach. The analysis is compared with PI and the best findings are achieved. The test system is modeled using the MATLAB/Simulink program.
