Enhancement of Power Quality in a DG-Integrated Smart Grid Using UPQC

P.K. Hota

Abstract


The goal of this presentation would be to demonstrate how an upqc conditioner may be used to improve the strength of a dispersed energy (DG) system (UPQC). Despite the potential advantages of DG, which include increased energy supply, reduced power system growth, and environmental friendliness, there are numerous problems assimilating DG into the system or sustaining it in standby mode. Voltage profile (PQ) is a significant technological barrier in dispersed energy (DG) power systems. Furthermore, harmonic and voltage collapse adjustments in DG networks significantly reduced PQ, affecting the stability of the system. As a result, the impact of PQ issues on a freestanding Diesel generator (which includes solar, wind, etc fuel fibroblast renewable sources of energy) is frequently analyzed in the field of UPQC. UPQC is implemented by trying to combine synchronous machine bounding box (SRF) and modified synchronous motor reasonably constant (MSRF) methodologies for generating reference current, a pulse width modulation power converters technique for trying to generate inverter pulses, and a PI controller for trying to regulate the Voltage level. Compensation for voltage instability using input power harmonics is calculated for a variety of source conditions (perfect and non-ideal) using a variety of control techniques including such SRF and MSRF.
