Coordinated Bidding Decision Model for Battery-Hydrogen Storage in Electricity and Frequency Regulation Markets

Under the dual background of rapid increase of new energy penetration rate and continuous deepening of power market reform, it is urgent to explore the advantages and complementary characteristics between power-based electric energy storage and energy-based hydrogen energy storage, so as to realize the synergistic optimization of the two to participate in the electric energy market and auxiliary service market. First, the overall structure of composite energy storage to participate in the electric energy market and frequency regulation ancillary service market auxiliary service market is constructed. Then, starting from the game relationship between electric-hydrogen composite energy storage as a price maker to participate in the electricity spot market, and considering the operation characteristics of electric and hydrogen energy storage, a twolayer optimization model of bidding game for electric-hydrogen composite energy storage to participate in the electric energy and frequency regulation markets is proposed. The upper electrichydrogen composite energy storage realizes its own comprehensive benefit maximization through bidding decision, and the lower electric energy market and frequency regulation market carry out joint clearing. Finally, the effectiveness of the proposed model is verified by arithmetic simulation.
