Requirements for dispatchers of shared 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.

Can a shared battery energy storage system provide ancillary service?

This paper proposes a framework for using a shared battery energy storage system (BESS) to undertake the PFR obligations for multiple wind and photovoltaic (PV) power plants and provide commercial automatic generation control (AGC) service in the ancillary service market at the same time.

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 time does a shared energy storage power station discharge?

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.

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 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.
