Abstract
A method for the decentralised solution of the congestion management problem in large interconnected power systems is presented. The multi-area congestion management is achieved through crossborder co-ordinated redispatching by regional transmission system operators. The co-ordination is performed through a pricing mechanism inspired by Lagrangian relaxation. The prices used for the co-ordination of the regional subproblem solutions are the prices of electricity exchanges between adjacent areas. Test results from the application of the method to the three-area RTS96 are reported.Keywords
