Realization of Novel Multi-Feeder UPQC for Power Quality Enhancement Using Proposed Hybrid Fuzzy+PI Controller

Abstract

At present the multi-feeder power distribution system is deteriorated with continuity of supply and poor power quality standards. In this multi-feeder distribution system, it is a regular consumer related issue which is acquired due to misfunctioning of massive non-linear load devices. These loads create the voltage/current imperfections on distribution networks which disrupts the power quality of distribution system. An efficient and reliable active compensation scheme is used for attaining enhanced power quality features at PCC of multi-feeder distribution system with effective control functions. The Multi-Feeder Unified Power Quality Compensator (MF-UPQC) is optimal choice for attaining enhanced power quality features and it is a combined operation of both shunt/series compensator driven by common DC-link. In this paper, a newly proposed MFUPQC is used to compensate all voltage-current PQ imperfections by using advanced intelligent control schemes. The performance evaluation of proposed MF-UPQC is verified by classical PI and proposed intelligent based Fuzzy and hybrid-Fuzzy control functions by using MATLAB/Simulink tool and results are conferred with comparisons.
