Impacts of Frequency Containment Reserve on the Optimal Coordinated Hydropower Scheduling in Three-Settlement Markets

This paper investigates the coordinated scheduling of hydropower plants in a river participating in a day-ahead, regulation and reserve markets. The gains in participating in the multiple sequential electricity markets are formulated through the linear programming. In the reserve market, the possibility of proposing an unsymmetrical frequency containment reserve (FCR) is considered for two scenarios in the winter and summer. Furthermore, the impacts of active time of regulation bids are investigated. The results show a moderate revenue increase by participating in the reserve market. Also, it states that providing the unsymmetrical FCR market will even increase revenue as an incentive for the owners to participate.
