Abstract
Microgrids (MG) are turning out to be progressively appealing to consumers and an incredible number of them will be introduced at their premises in the near future as they allow utilization of freely available renewable energy sources. Because of high penetration of distributed generation units with distinctive sorts of loads, microgrids can be subjected to power quality and control issues. Some of them are voltage swells and sags, and low power factor which further oblige reactive power compensation. This paper exhibits the custom power device particularly Unified Power Quality Conditioner (UPQC) in alleviating the issue of voltage sags and swells happening in microgrid. A microgrid is modelled and simulated with diverse loading conditions bringing on power quality issues. The incorporation of UPQC in microgrid is analyzed for providing reactive power compensation to overcome these concerned issues. In addition Photo Voltaic based common DC link energy source is used in UPQC. The overall UPQC effectiveness is observed in mitigating power quality problems is observed in Matlab/Simulink.
