Research on a bidding strategy and coordinated scheduling of distributed energy storage aggregators in frequency regulation market

Existing research on market strategies for distributed energy storage aggregators has not yet considered the integration of bidding decisions and incentive pricing， nor does it analyze the regulation capabilities of user-side energy storage aggregation under different operation modes. To address these limitations， firstly， based on a quantitative analysis of distributed energy storage operation modes， operational costs， and economic benefits， the incentive pricing-user participation curves for peak-valley arbitrage and backup storage for base stations are established， and a model for evaluating the dispatchable capacity of the user-side energy storage considering the operation modes is developed. Secondly， by integrating the dispatchable capacity estimation method for user-side energy storage， a joint bidding and pricing optimization model is established for distributed energy storage aggregators in frequency regulation and electric energy markets， with the goal of maximizing trading revenue. Finally， through a case study analysis， it is demonstrated that the proposed bidding strategy and coordinated scheduling of distributed energy storage aggregators in the frequency regulation market can increase aggregator revenue while ensuring the feasibility of the decisions.
