Energy storage and shared electricity

What is shared energy storage?

With shared energy storage, multiple consumers will have access to the energy storage by charging and discharging the energy storage depending on their own needs. In this case, consumers can reduce the burden of the installation of energy storage by sharing initial investment costs.

What is community shared energy storage (CSES)?

Community shared energy storage (CSES) is a solution to alleviate the uncertainty of renewable resources by aggregating excess energy during appropriate periods and discharging it when renewable generation is low. CSES involves multiple consumers or producers sharing an energy storage system.

Should energy storage be shared?

Considering these aspects, there has been an increasing interest in sharing energy storage among individual consumers, specifically in a residential community. With shared energy storage, multiple consumers will have access to the energy storage by charging and discharging the energy storage depending on their own needs.

Does shared energy storage reduce energy use?

The largest increase in energy storage use and decrease in the use of electricity from the grid to meet demand occurs in the fall experiment when using shared energy storage instead of individual energy storage, but since electricity prices are low, the cost reduction is not the greatest compared to the other seasons.

How can energy storage be efficiently used?

Moreover, energy storage can be efficiently used by sharing among multiple energy consumers with different demand patterns. The larger capacity of the shared energy storage allows for more charging and discharging of energy. The nature of the shared energy storage allows different consumers to charge and discharge at the same time.

Will residential consumers use individual energy storage or shared energy storage?

Given the historical data set, we assume that residential consumers will use individual energy storage or shared energy storage based on the parameter settings. For the default setting of energy storage, the capacity is determined based on the average hourly electricity demand load.
