The power market's frequency regulation is being gradually influenced by flywheel energy storage's high frequency modulation performance with the development of new power systems. To address the issue that the traditional marginal clearing method overly focuses on frequency modulation performance and neglects cost-effectiveness
a market clearing strategy for modulating frequency of flywheel energy storage using Stackelberg game is proposed. A cost model for the charge and discharge of flywheel energy storage is developed firstly. To optimize the quote and minimize frequency regulation and auxiliary expenses
the Stackelberg game method is used with consideration of the operational constraints of flywheel energy storage
thermal power units and wind farms. Finally
according to the real-time frequency modulation demand
the clearing is carried out according to the marginal price ordering. The simulation results show that the proposed mechanism ensures a reasonable winning rate and revenue for flywheel energy storage in the frequency modulation market
this aids in lowering the total cost of frequency modulation and enhancing the system's overall performance. Compared with the traditional method
this method improves the frequency modulation income of the unit and effectively promotes the consumption of new energy.
