Solar photovoltaic interconnected ZSI-unified power quality conditioner to enhance power

Abstract

In order to ensure that all the connected Equipment in the distribution network operates smoothly, the voltage stability of photovoltaic (PV) integrated distribution systems is very important. Sustaining the voltage profile when integrating PV is a particularly difficult issue. The primary goal of this article is to provide a consistent voltage profile to a sensitive load. A three-phase PV integrated distribution system has been chosen for investigation. An innovative feature of this system is that UPQC DVR and STATCOM systems are powered by Z-source inverters instead of traditional inverters. The ability to actively decouple power is the primary benefit of utilizing a Z-source inverter. The objective of the study effort is to use this new UPQC to synchronize a solar PV system with the distribution system. For the UPQC with battery energy storage system (BESS), the research study examines and develops the most appropriate control approach. A UPQC is a device that is used to integrate solar panels and improve the voltage stability of the distribution system. The prototype model is being developed, and the experimental findings confirm the main objective.
