In the absence of energy storage to participate in auxiliary services, the power system uses thermal power to participate in deep peak regulation to reduce the curtailment of wind power companies. In this mode, the changes of on-grid electricity and income of wind power compa-nies and thermal power companies are shown in.

Existing literature has extensively studied the markets in which energy storage participates, mainly focusing on the energy market and auxiliary service market. The revenue from the market is closely related to the market''s load demand and electricity prices 1,2]. Energy storage can gain profits in the energy market by utilizing market price differentials through energy trading
SESS only participates in the ancillary service market, leading to a lower service price in the ancillary service market than in Case 1. The electricity spot market price remains unchanged and equal to the original market price, due to the prioritization of the bidding strategy in Case 1 that avoids significant changes in market prices. However, the bidding quantity is
Household battery energy storage (HBES) is expected to play an important role in the transition to decarbonized energy systems by enabling the further penetration of renewable energy technologies while assuring power grid stability. However, the hitherto high installation cost is a key barrier for further deployment of HBES. Therefore, in order to improve its

The market trading prices for ancillary services in each region are shown in the table3.
As the scope of pilot power auxiliary services continues to expand, major provincial power companies are clarifying the main status of demand-side response resources and energy storage resources
Adopting the dynamic pricing mechanism of ancillary service, only promotes energy storage to participate in reducing peak demand and FR but also balances the interest relationship between the upper and lower levels. The ideal power price and the optimal layout of energy storage system were derived using the CPLEX iterative solution.
Numerous studies have focused on the ancillary service compensation mechanism in the electricity market. Wei et al. proposed a stepped compensation mechanism considering the cycle depth for the market of reducing peak demand, and a compensation mechanism considering the opportunity cost of FR for the FR market.
Furthermore, under the dynamic electricity price, the magnitude of the energy storage in ancillary services is stronger, exhibits increased income in the renewable energy, reduces the power purchased from the upper grid. So operating cost of power grid and joint costs are also down. 6.2.3.
Payment for ancillary services by power customers is an inevitable step in the transition of the existing ancillary services market from a “zero-sum game” between generators to true marketization.
Conclusion The pricing of dynamic ancillary services and the configuration of energy storage were optimized using a bi-level optimization model developed on multi-stakeholder scenarios, and a bi-level iterative solution was implemented using CPLEX.
Therefore, the dynamic ancillary market price effectively guided energy storage to participate in reducing peak demand and reduced the valley-to-peak of load. The peak shaving compensation price was selected to be 0.7 yuan/kwh, and the valley filling compensation price was −0.2 yuan/kwh.
