Abstract: A new type of power system needs to build a reasonable climbing market to effectively enhance the flexibility of system operation and cope with the strong volatility brought about by the high penetration rate of new energy sources. Currently, the only participants in the ramping market are generally thermal generators and usually receive the benefits of both the energy and ramping markets. For this reason, this paper proposes a method of joint clearing of electric energy and climbing market, including energy storage. First, the system climbing demand is determined based on the net load curve and the new energy output forecast error. Second, the natural climbing capacity of the system is determined based on the security-constrained economic dispatch model, which determines the amount of system climbing missing. Then, a joint clearing model of the electricity market and the creeping market will be constructed, in which thermal generating units, energy storage, demand-side response, and wind and solar abandonment are all involved. Among them, the thermal power generating units adopt the virtual volume-quote method to participate in the ramping market, and the energy storage adopts the maximum ramp-up capacity and fixed compensation to participate in the ramping market. When the sum of the ramping capacity of thermal generating units and energy storage still fails to meet the ramping demand, demand response and wind and solar abandonment will be used to maintain the power system's load balance. Finally, the proposed method is verified by an example simulation with actual operation data in a province. Simulation results show that the joint clearing method of the power and ramp-up market proposed in this paper can maximize the system's flexibility, avoid the double benefit problems, and improve the new energy utilization rate.
