Wavelet based power quality assessment of wind energy source integrated 5-bus system under sudden load conditions in presence of FACTS devices

Abstract

The structure, operation, and planning of electric power networks will undergo considerable and rapid changes due to increased global energy consumption. The requirement of renewable energy sources due to the increase of electrical demand. This paper presents wind energy integration with electrical grid under impact on sudden load conditions. To fill the demand and supply gap requires reactive power. To compensate reactive power more prominent devices are needed. The Static Synchronous Series Compensator (SSSC), Static Synchronous Compensator (STATCOM) and Unified power flow controller (UPFC) are the members of the Flexible AC Transmission system family having very attractive features of series and shunt reactive power compensating devices. The proposed research work is carried by wavelet multi resolution analysis using Bior1.5 mother wavelet under Power Quality issue of sudden load 150MW is introduced at bus-3, which can be compensated by a wind energy source and FACTS devices. The analysis of 5-bus network model of sudden load impact is tested and observed that the effectiveness of the system with Wind Energy source integration in presence of SSSC, STATCOM &UPFC.
