The role of virtual energy storage

What is a virtual energy storage system?

2.1. Concept A Virtual Energy Storage System (VESS) aggregates various controllable components of energy systems, which include conventional energy storage systems, flexible loads, distributed generators, Microgrids, local DC networks and multi-vector energy systems.

How can energy storage extend the lifespan of energy storage units?

The strategy aims to extend the lifespan of energy storage units by avoiding deep over-charging and over-discharging. By dynamically adjusting the virtual inertia and damping while satisfying SoC constraints, the proposed strategy effectively stabilizes grid frequency and mitigates power fluctuations.

Does 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.

Does energy storage play a role in energy management of end users?

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 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.

Why are virtual power plants important?

Virtual power plants (VPPs) could be the key to helping us bring more clean power and energy storage online. Governments and private companies alike are now counting on VPPs’ potential to help keep costs down and stop the grid from becoming overburdened.
