Title: Influence of FACTS Devices on Congestion Management in Deregulated Power System
Authors: J. Sridevi and J. Amarnath and G. Govinda Rao
Abstract: Deregulation of electric industry has a direct impact on the increasing number of transactions. This lowers the available margin and leads to the increased congestion of transmission lines. Thus the system becomes more vulnerable to collapse. Analyzing the system security and congestion, and determining their effects on pricing becomes more important than ever in the deregulated environment. This paper proposes a method for the placement of Flexible AC Transmission System devices in deregulated power system to reduce congestion. Locational marginal price is used to study the effect of congestion in the pricing model. The proposed method is based on Locational Marginal Price differences of Optimal Power Flow to find the optimal location of Thyristor Controlled Series Capacitor (TCSC) and Thyristor Controlled Phase Angle Regulator(TCPAR) devices. The overall objective function can be either to minimize the congestion rent or to maximize the social welfare. The proposed method is tested on an IEEE 24rts system, an IEEE 57 bus system and an IEEE 118 bus system. Results shows that the proposed method for TCSC is capable for reducing the congestion rent and for TCPAR is capable for maximizing the social welfare.
