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 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 a generalized energy storage system?
