The reason: To shut down 1 MW of gas capacity, storage must not only provide 1 MW of power output, but also be capable of sustaining production for as many hours in a row as the gas capacity operates. That means you need many hours of energy storage capacity (megawatt-hours) as well. The study also finds that this capacity substitution ratio
Learn MoreThis allocation method, although straightforward for the overall system to distribute the costs associated with the shared energy storage power station to each renewable energy power station involved, does not take into account the practical use rates of the shared energy storage services and may appear unjust to stakeholders.
Reduce total costs by up to 36% through the dynamic weighted allocation method. The concept of shared energy storage in power generation side has received significant interest due to its potential to enhance the flexibility of multiple renewable energy stations and optimize the use of energy storage resources.
For instance, in Guangdong Province, new energy projects must configure energy storage with a capacity of at least 10% of the installed capacity, with a storage duration of 1 h . However, the selection of the appropriate storage capacity and commercial model is closely tied to the actual benefits of renewable energy power plants.
The subsequent profits of the energy storage station can be distributed to the participating new energy power plants through game-theoretic methods, such as Nash bargaining or Shapley value, or according to the predetermined investment proportions in the contract.
In this way, the cost of abandoning wind and solar power, as well as the total costs, will be affected. Therefore, evaluating how the power abandonment cost coefficient influences the operation of the shared energy storage power station and the allocation of associated costs presents significant importance.
Moreover, the shared energy storage power station is generally discharged from 11:00 to 17:00 to meet the electricity demand of the entire power generation system. In Case I, the state-of-charge gradually increases in the morning, fluctuates between 08:00 and 22:00, and returns to its initial level by 24:00.
