Inter-utilities power-exchange coordination: A market-oriented approach

A decentralized operation of the transmission grid for scheduling inter-uti lities power exchanges is proposed. This approach is well suited for market -oriented environments; it achieves a market equilibrium while the operatio nal independence of each interconnected utility is preserved. We employ dec omposition-coordination techniques in combination with an Interior-Point/Cu tting-Plane method in order to reduce the number of iterations of the decom position algorithm, The paper includes test results on IEEE-based systems.
