Design of cloud service transaction mechanism for distributed energy storage in multi-park based on DAF-IDO energy storage action deviation quantity

At present,the business model and market mechanism of cloud energy storage are still immature, and the way of user participating in cloud energy storage service is relatively single. At the same time,the distributed energy storage is mostly used for user-side operation with renewable energy to smooth out the volatility of its output,and its uncertainty leads to the deviation of day-ahead forecasting-intraday operation (DAF-IDO). For that,the multi-park distributed energy storage cloud service transaction mechanism based on DAF-IDO energy storage action deviation quantity is proposed,which combines operation with transaction to provide distributed energy storage users with a new market approach for participating in cloud energy storage services while addressing the DAF-IDO deviation. The method for determining DAF-IDO energy storage action deviation quantity is established,enabling park operators to quantitatively calculate the supply and demand of energy storage in the park. Then,the distributed energy storage cloud service transaction mechanism based on combination auction between parks is developed,and the valley period compensation mechanism is added to the cloud energy storage pricing mechanism to enhance users'enthusiasm and autonomy in participating in cloud service while considering the economic interests of all parties. The feasibility and rationality of the mechanism is verified through case study simulation. © 2024 Electric Power Automation Equipment Press. All rights reserved.
