Improvement of Load Regulation in 33- Bus Closed loop Distribution System using Sliding Mode Controlled Unified Power Flow Controller

Recent developments in FACTS-devices have produced conditioner equipments to mitigate sag and attenuate Total Harmonic Distortion (THD). U.P.Q.C has been urbanized as a FACTS controller between feeding end & far end of distribution system. The UPQC is capable of improving the voltage profile and reducing THD of distribution system by regulating voltage using FOPID (Fractional-order-proportional-integral-controller) and utilizing SMC (sliding-mode-controller) controller. This work proposes UPQC for Thirty Three Bus System (TTBS). The objective of this work is to enhance-voltage-profile of TTBS. The TTBS in open loop & closed loop-TTBS UPQC using FOPID and SMC-controllers are-modeled pretend and their consequences are represented. The outcomes are estimated in terms of settling-time, steady-state-error. The outcomes indicate that SM Controlled TTBS system has better response than FOPID controlled TTBS system.
