Shared energy storage station construction cost standard

Should shared energy storage power stations be allocated?

This 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.

What is the objective of a shared energy storage power station optimization model?

The optimization objective is to minimize the annual comprehensive cost (including investment cost and operating cost) of the shared energy storage power station. Objective Function for lower-level Optimization Model.

Does a shared energy storage system reduce the cost of energy storage?

The results show that the construction of a shared energy storage system in multi-microgrids has significantly reduced the cost and configuration capacity and rated power of individual energy storage systems in each microgrid.

How are shared energy storage services allocated?

To enhance the use of the shared energy storage services across multiple renewable energy power stations and allocate the associated costs effectively, three different allocation methods are initially formulated, which include the uniform allocation method, the predictive weighted allocation method, and the dynamic weighted allocation method.

What is energy storage construction cost?

These metrics include the distributed shared energy storage construction cost of C i n v, the energy storage power purchase cost of C e b, and the energy storage profit of C e s. The construction cost is made up of power cost and capacity cost, which are related to the energy storage plant P e s s, i m a x and E e s s, i m a x, respectively.

What is a shared energy storage station?

The shared energy storage station provides leasing services to multiple microgrids, enabling microgrids to use energy storage services without building their own energy storage systems.
