Placement of Facts Devices Using Genetic Algorithm for Restructured Power Market

Abstract

Electricity, unlike other commodities, cannot be easily stored and supply has to meet demand at all times. The transportation of electricity is constrained by physical laws which need to be satisfied constantly in order to maintain the reliability and security of the power system. The restructuring of the ongoing power system requires an opening of unused potentials of transmission system due to environmental and cost problems which are major hurdles for power transmission network expansion. FACTS can be alternative to reduce the flows in heavily loaded lines, resulting in an increased loadability, low system loss, improved stability of the network and reduced cost of production. Series FACTS devices such as TCSC, with its ability to directly control the power flow can be effective to improve the operation of transmission network. FACTS devices can be an alternative to reduce the flows in heavily loaded lines, resulting in an increased loadability, low system loss, improved stability of the network, reduced cost of production and fulfilled contractual requirement by controlling the power flows in the network. This paper suggests, first, the few optimal locations of FACTS devices and then determines the best optimal location in order to reduce the production cost along with the device cost. The allocation and requirement are also discussed. The effectiveness of the proposed methods is demonstrated on IEEE 30-bus system.
