Optimal Placement of Fuzzy Based Nonal Switched UPQC Topology with Distributed Generation for the Power Quality Enhancement in IEEE 14 Bus System

Abstract

An Unified Power Quality Conditioner (UPQC), owning the integration of shunt and series Active Power Filter (APF), has become a standard accepted solution in the area of current and voltage harmonics mitigation of a power system network. This paper furnishes a novel approach of nonal switched UPQC topology, supported with Distributed Generation (DG), aiming at the power quality enhancement and position optimization, placed at different locations in a standard IEEE 14 bus system. In addition to this, the behaviour of the proposed topology is analysed using Fuzzy Logic and Space Vector Pulse Width Modulation (SVPWM) as control algorithms and the outcomes are compared with the historical twelve switch UPQC topology. Simulation results of the proposal modelled in MATLAB/SIMULINK reveals the superiority of nonal switch UPQC and the optimal position of the proposed conditioner, for mitigating the harmonic issues in the standard IEEE 14 bus system.
