Virtual capacity expansion energy storage

How can virtual energy storage share and capacity allocation improve energy management?

Virtual Energy Storage Sharing and Capacity Allocation Abstract:Energy storage can play an important role in energy management of end users. To promote an efficient utilization of energy storage, we develop a novel business model to enable virtual storage sharing among a group of users.

What is a virtual energy storage system?

The concept of a virtual energy storage system (VESS) is based on the sharing of a large energy storage system by multiple units; however, the capacity allocation for each unit limits the operation performance of the VESS. This study proposes an operation strategy of a dynamic VESS for smart energy communities.

How do aggregators share energy storage?

To promote an efficient utilization of energy storage, we develop a novel business model to enable virtual storage sharing among a group of users. Specifically, a storage aggregator invests and operates the central physical storage unit, by virtualizing it into separable virtual capacities and selling to users.

Can storage virtualization reduce energy storage investment?

In our simulation results, the proposed storage virtualization model can reduce the physical energy storage investment of the aggregator by 54.3% and reduce the users' total costs by 34.7%, compared to the case where users acquire their own physical storage.

What is grid-scale virtual energy storage?

This article presents a novel method called “grid-scale virtual energy storage” that harvests free energy storage from properties inherent to control of multiarea power systems, thereby increasing the amount of renewable generation that a system can tolerate before its frequency stability is compromised.

Does a virtual energy storage system make a profit?

Summary of virtual energy storage system (VESS) research. Most contemporary studies have only focused on profits by the economies of scale using a VESS. However, the usage of a VESS does not always generate benefits for community participants [ 26 ]. Therefore, it is necessary to increase the additional gain when using VESSs.
