Optimization of Loss Minimization Using FACTS in Deregulated Power Systems

Abstract

Losses are an important parameter of consideration for mitigation and thereby enhancing the Available Transfer Capability of Power Systems. Loss mitigation is a two stage process the first stage is the Planning phase and the second stage is the Operational phase. The paper discusses briefly the Planning phase activities. The various methods of mitigating the losses in the Operational phase have been presented in the paper with emphasis on one technique the Flexible Alternating Current Transmission System devices. The Flexible Alternating Current Transmission System Devices are the latest power electronics devices by which losses can be reduced and transfer capability enhanced. Thyristor Control Series Compensator is used to reduce losses. The method is tested on IEEE 9 bus, 14 Bus and 30 bus systems and validated. Results have been presented and analyzed in this paper.
