Analysis of market coupling based on a combined network and market model

In this paper the possible implementation and the efficiency of multilateral market coupling are evaluated. Market coupling is known as the cooperation of power exchanges and other market players in order to utilize the limited capacity of a meshed electricity transmission system in an efficient way. Based on a three-part combined network and market model of the Central Western European region, the congestion management is simulated and possible alternatives in the different steps of the practical execution are compared to each other. The results are rated from an economic and technical point of view in terms of system-wide welfare as well as utilization and security of the congested lines.
