Price standards for auxiliary services of energy storage power stations

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.

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 auxiliary service costs compensated?

They have proposed three compensation methods for auxiliary service costs, namely, proportional to the amount of wind power fed into the system, proportional to the amount of wind power absorbed from the system, and based on the power market model. These methods are analogous to those used for peak power integration.

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.

How does the power abandonment cost coefficient affect shared energy storage power stations?

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.

What is shared energy storage assistance?

The objective is to improve the efficiency of the power generation system by incorporating shared energy storage assistance and allocating the associated costs based on the use of various renewable energy stations.
