Performance Analysis of Solar PV array and Battery Integrated Unified Power QualityConditioner for Micro-grid Systems

Abstract

An automated approach for switching between grid-connected and independent modes of operation for a solar PV array with a battery-integrated power quality conditioning system (PV-BUPQC) is described and studied in this study.  A shunt and active filters in series are joined side by side using a shared DC-link in this arrangement.  The method solves the problem of producing clean energy while simultaneously improving electricity quality.  In addition, important loads are always powered regardless of grid availability because of the automatic transition.  A PV-B-UPQC system's automatic transition with little impact on local loads is one of the main obstacles tackled.  Experimental validation of the system operation is carried out under various dynamic conditions commonly encountered at a modern distribution network, including automated transition, electricity supply variations, grid unavailability, variation in the production of solar energy, load variation, and so on. Power quality, continuous power production, automated transition, solar photovoltaic generation, battery-powered storage, and a single quality conditioner for power are all terms that may be found in an index.
