Analysis of the operating characteristics of cloud energy storage

What is cloud energy storage?

Cloud energy storage (CES) in the power systems is a novel idea for the consumers to get rid of the expensive distributed energy storages (DESs) and to move to using a cloud service centre as a virtual capacity.

Is a heterogeneous cloud energy storage system economically feasible?

The economic feasibility of a heterogeneous cloud energy storage (HCES) system is investigated in [ 44 ]. The HCES uses four types of batteries known as Lead-acid, Lithium-ion, Sodium Sulphur, and Redox flow technologies.

What is cloud energy storage (CES)?

Based on the combination of sharing economy and electric energy storage technology, Kang et al. proposed the concept of Cloud Energy Storage (CES) in 2017 .

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.

Which energy storage utilization model is best for power plants?

Compared with the traditional self-built energy storage utilization model, the CES model provides a cheaper solution for the power plants, as there is normally complementarity among energy storage utilization demands of different power plants.

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.
