Implementation of UPQC Alleviating Power Quality Issues in a Hybrid Grid Integrated System
Authors: , ,
Abstract: The advances in the field of power systems, distribution utilities ordinance the associated non-linear advance loads compliance with the stern power quality (PQ) enhances the reliableness of the delivery system to provide demands of censorious loads and subtle automation systems. Hurdles for sustaining quality power are linked with the continuation of elemental VAR power necessities of loads; voltage dips and swells at the point of common coupling (PCC) due to sudden switching of large industrial loads as well as VAR power indemnifying capacitors and harmonic distortions due to voltage and/or current along with non-linear loads. The harmonic distortions are pertained to be the major drawback the root cause of the PQ issues also the fluctuating pattern by loads causes degradation of voltage waveform which has been presented with variable loads. Hence, custom power device (CPD) materialized as Unified Power Quality Conditioner (UPQC) settles the issue. Intention of the work is to bring spontaneity in both the voltage and current waveform with the Sinusoidal current control strategy (SCCS), a time dominion strategy founded over instantaneous pq-theory executed with MATLAB 2016a. The results are well analyzed with proper explanation for selection of the said strategy for the UPQC. As an elementary and inherent strategy, it has titanic prospects further to be applied under photo-voltaic environment associated with a proton exchange membrane fuel cell (FC) in a hybrid grid integrated (HGI) system.
