Optimal placement of facts devices in power system for power quality improvement

Abstract

Power Quality is an important issue in power systems where compensating devices play a very important role to improve voltage profile reduce power losses and mitigate power quality problems. Implementation of the Flexible AC Transmission Systems (FACTS) devices to optimally in power flow of IEEE 30 & 57 bus systems to shrink power losses and improved voltage profile for power quality improvement. In this paper four types of FACTS controllers STATCOM, SVC, TCSC and UPFC are implemented by conventional method for power quality improvement. Here an assessment is also made between conventional method and evolutionary computation method to authenticate performance, results shows usefulness of the projected method.
