In the context of continuously increasing penetration of new energy sources,flexible resources such as en-ergy storage play a crucial role in constructing a new power system.Based on the current status of the electricity mar-ket in Anhui Province,a multi-stage collaborative trading strategy for independent energy storage in the electricity market is proposed.Firstly,a medium-to-long-term transaction settlement model is introduced.Then,to address the uncertainty of electricity price and power forecasting,a day-ahead joint clearing model for electric energy and re-serve ancillary services characterized by multiple probability scenarios is established.Furthermore,a separate trad-ing model for intraday deviations is developed.Additionally,an analysis is conducted on the impact of energy stor-age aging costs on revenue.Finally,simulations are conducted with the objective of maximizing independent energy storage revenue,and the results indicate that the proposed mechanism can effectively enhance market returns for in-dependent energy storage,providing insights for the development of the electricity market.
