Current status of shared energy storage fields

What is shared energy storage?

Shared energy storage is generally applied in the supply, network, and demand sides of power systems. The shared energy storage at the supply side is mainly utilized for renewable energy consumption ( Zhang et al., 2021 ). The proportion of renewable energy is greatly increasing due to the continuous promotion of "carbon peaking and neutrality".

How do shared energy storage operators interact with users?

The interaction between shared energy storage operators and users relies on the market structure of shared energy storage, including the sharing structure, trading products, and pricing mechanism. The sharing structure characterizes the investors and owners of energy storage resources and reveals the role of shared energy storage operators.

How to create a shared energy storage community?

Community setup The first step to have shared energy storage is to form communities which are built by using the k -means approach. The geographical locations (longitude and latitude) are used to cluster the households. In this case, K = 3 is used to form three communities due to the distance limitation of CES and the road intersection.

Are shared energy resources better than private energy storage?

We demonstrate the advantages of using shared as opposed to private energy storage. Distributed Energy Resources have been playing an increasingly important role in smart grids. Distributed Energy Resources consist primarily of energy generation and storage systems utilized by individual households or shared among them as a community.

What is a shared energy storage mode?

The shared energy storage mode can attract more capital to actively invest in the energy storage industry, accelerate the development of energy storage scale and maximize the efficiency of energy storage utilization. Transactive energy (TE) ( Yang et al., 2020 ): it is the application of sharing economy in the field of the electricity market.

Do households own energy storage and not share energy resources?

In this part, we consider the case where households own individual energy storage and do not share these resources, i.e, own PESs. The first observation is that when households install PV systems and PESs, the flexibility of controlling their demand is much higher and thus the aggregator’s electricity cost can decrease significantly.
