Self-invested and self-built energy storage projects

Can self-built and leased energy storage be used for shared energy storage?

A novel hybrid mode that integrates self-built and leased energy storage for configuring shared energy storage. A step-cost decrement model is established for the self-built energy storage mode. A two-stage robust optimization model is developed considering supply-demand uncertainty.

Who owns the energy storage system?

The grid subsidiary is the owner of the energy storage system. The third type is the third-party investment. Under this investment model, the energy storage system is invested and operated by third partied.

How much does self-built energy storage cost?

The annual O&M cost per power of self-built energy storage (β sel P) is 18.25 ¥/kW; the unit annual O&M cost per capacity of self-built energy storage (β sel E) is 28.95 ¥/kWh.

What is a composite energy storage business model?

The composite energy storage business model is highly flexible and can fully mobilize power system resources to maximize the utilization of energy storage resources. The model can reduce the risk of energy storage investment and accelerate the development of energy storage. 4.3.2. Microgrid model

What is shared energy storage & other energy storage business models?

Through shared energy storage and other energy storage business models, the application scope of energy storage on the power generation side, transmission and distribution side, and user side will be blurred. And many application scenarios can realize the composite utilization of energy storage according to demand.

What are the emerging energy storage business models?

The independent energy storage model under the spot power market and the shared energy storage model are emerging energy storage business models. They emphasized the independent status of energy storage. The energy storage has truly been upgraded from an auxiliary industry to the main industry.
