Energy Storage Power Station Cost Distribution

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 a shared energy storage-assisted power generation system?

3. Combined operational and cost allocation models for shared energy storage-assisted power generation systems Here, the power generation system comprises a collection of renewable energy power stations (n = 1, 2, …, n, …, N), specifically wind power plants and photovoltaic power plants, which are connected to a shared energy storage power station.

What is shared energy storage?

The role of shared energy storage on the power generation side of the power system differs from the previous two applications. It serves to support the operation of thermal power units, enhance the reliability of renewable energy generation connected to the grid, and potentially remove the need for constructing alternative units.

How can shared energy storage assistance improve power system cost evaluation?

These methods improve the precision of power system cost evaluation and enable renewable energy stations to allocate their responsible costs effectively. Furthermore, a combined operational and cost distribution model was formulated for power generation systems utilizing shared energy storage assistance.

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.

How can shared energy storage reduce energy costs?

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.
