Shared energy storage power station benefit calculation

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 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.

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.

How can energy storage be shared in distribution networks?

By changing the parameters of the power loss rate in transmission lines, the investment budget, the power cost and capacity cost, and the feed-in tariffs of wind and PV power, the proposed model is able to share energy storage appropriately in distribution networks and operate the whole power generation system economically.
