6 FAQs about [Energy storage aggregation control]

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 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?

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.

Is energy storage system a viable solution for high-proportion renewable power integration?

Energy Storage System (ESS) has flexible bidirectional power regulation capabilities and has provided an effective means to address the challenges of high-proportion renewable power integration. However, hindered by many factors, the large-scale development and application of ESS still face many bottlenecks.

What is a typical application scenario of energy storage on the grid?

Another typical application scenario of energy storage on the grid side is the emergency power support for the system such as emergency reserve. Considering that the provision of grid-side CES services relies on solid grid infrastructure, the failure of the grid may cause the cascading failure of CES.

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.
