Power Band Model Based on Flow Network and Weekly Unit Commitment Problem Considering Reserve Market

Abstract

The reserve market was established in 2021. So far, power producers sell the electricity in the energy market and through the bilateral contract. Currently, power producers can sell the reserve in the reserve market. In order to earn well, they have to sell both energy and reserve. When they sell the reserve in the reserve market, they have to control bands of thermal generators preparing for the activation of the reserve. In this study, we present a unit commitment method which can schedule the operation of bands considering bidding for the energy and reserve market. In order to model this unit commitment problem, we apply a flow network. We link a network of transitions of band with one of transitions of on and off. The numerical results show that trading in the reserve market improves power producer's profit by 4.19% and the proposed method can schedule the operation of bands appropriately.
