Different Power Quality Issues of the Energy Power System with Their Analysis and Mitigation Techniques

Abstract

The power systems have the utilization of the power electronics devices for electric power supply becomes a very common trend. These power electronics devices work like as a nonlinear loads and produce the distortion in the system which introduces unwanted harmonics for reduction of the PQ supply system. The power quality of the system becomes very important issue due to the utilization of the power electronics devices and their application of day to day life. Power suppliers faced a number of problems for transferring the power supply from generating station to the end users and load demand centers with minimum investment or high reliability of the system. Different power quality monitoring techniques describe with their applicable solution of the issues. Custom power devices are utilized for achieving the better power quality through the mitigation techniques like UPS, TVSS for the system. Due to the different advantages of the power quality S-TATCOM can be utilize for renewable energy system. Spinning reserve is the traditional method for improving the power quality of the system. Flow chart of the power quality of the system provide the information of the about the problem identification and evaluation of the problem of power quality in first stage. It can be divided into five parts of the problem evaluation like voltage sag, transients, flicker, voltage regulation and harmonics distortion. Standards of the power quality with their different issues in the energy system for monitoring techniques have been discussed with use of particular custom power devices.
