Aggregate energy storage

What types of energy storage can be aggregated?

The type of energy storage to be aggregated can be selected specifically to achieve an effective replacement of conventional power regulation resources. For example, base station batteries perform well in power regulation and are suitable for power applications such as frequency regulation.

What is cloud-based energy storage?

A new type of business model has been proposed that uses cloud-based platforms to aggregate distributed energy storage resources to provide flexibility services to power systems and consumers. In such cloudbased platforms, storage resources can be more strategically used so that the unit cost of providing the service can be reduced.

What is aggregated reuse of multiple energy storage?

The first part is called “aggregated reuse of multiple energy storage”, which refers to the aggregation of various types of energy storage resources for shared use. This part focuses on the “cloud” characteristic of energy resources and forms an energy storage resource pool which can be referred to as the energy storage “cloud”.

What is decentralized reuse of aggregated energy storage?

The second part is called “decentralized reuse of aggregated energy storage”, which focuses on the “cloud” characteristic of energy storage service and refers to the virtualized energy storage service provided through the aggregated energy storage facilities. Fig. 2.

What is a generalized energy storage system?

Unlike typical electric energy storages such as lithium batteries which can actively respond to regulatory commands, the generalized energy storage suppliers will inevitably give priority to ensuring the safe and reliable operation of their own systems, and then use idle energy storage capacity to achieve arbitrage in the CES system.

Will energy storage provide flexibility and regulation services in future power systems?

Abstract: With the growing penetration of renewable energy and gradual retirement of thermal generators, energy storage is expected to provide flexibility and regulation services in future power systems. Battery is a major form of energy storage at the demand side.
