POWER STABILITY ANALYSIS OF A TRANSMISSION SYSTEM WITH A UNIFIED POWER FLOW CONTROLLER USING TRANSFORMATIVE IN TRINSIC ALGORITHM

The unified power quality conditioner is the equipment used for regulated voltage distortion and voltage unbalance in a power system. UPFC can enhance the power to flow through the transmission system by controlling the power flow and voltage stability of the transmission line within their limits. This paper presents a control scheme and Theoretical derivation of the unified power flow conditioner and the simulation results are compared and contrasted in detail. UPFC is a combination of shunt Active and series active power filters. UPFC contains a DC link capacitor in a single-phase voltage source inverter with two back to back connected, three-phase three-wire and three-phase four-wire are arranged. The fundamental target of this work is to determine the causes and impacts of power quality problems, specifically voltage sag, voltage swell, power factor, and Total Harmonics Distortion (THD) and enhance the power quality of a transmission system by UPFC based Transformative Intrinsic Algorithm (TIA). The Simulation of the proposed method is developed by Mat lab Simulink software, and the simulation result shows, the proposed method gives better solutions to control the power imbalance in the distribution system with its cost-effectiveness.
