Market clearing framework for an integrated market for manually activated control reserves and redispatch in Switzerland

A core function of each Transmission System Operator is the procurement of Ancillary Services (AS) necessary for a stable and reliable operation of the system. This paper presents the basis of a new market design in self-scheduling market structures, that is to be implemented in the future. The new design aims at an optimal deployment of manually activated AS products for a secure and balanced operation of the transmission network. Such products are currently being activated for different operational goals, although they have common technical characteristics. Possible positive outcomes from the establishment of such a market would be to combine the advantages of various products, eliminate arbitrage possibilities and have one common and liquid marketplace. To this end, a Security Constrained Optimal Power Flow was invoked, able to also accommodate consideration of uncertainties. The developed algorithm was used to evaluate specific cases in the Swiss power system.
