Fuzzy-Logic-Controlled Four Bus Micro-Grid System Employing-Hybrid-Power-Flow-Controller

Abstract

Hybrid –Power*Flow*Controller (H.P.F.C)finds place between weak buses in multi-bus-systems to moderate the-effects of-voltage-sag. _This exertion deals–with-PQ-enhancement-of-4Bus*system (F.B.S) using H.P.F.C. Simulation is done for open loop and closed loop HPFC 4bus-system with HC (Hysteresis controller) and Fuzzy Logic controller –and-the-outcomes are compared-in-terms-of settling time &steady-state-error. The outcomes represent that the-superior-performance-of Closed-loop-HPFC-Four-bus system with-fuzzy-logic-controller. The-simulation-outcomes represent the ability of the H.P.F.C in MGS to improve the power-quality.Settling time is abridged from0.87 to 0.62sec and steady-state-error of voltage in FBS is abridged from0.9 to0.1 V using FLC.
