Are there any gaps in energy storage technologies?

Even though several reviews of energy storage technologies have been published, there are still some gaps that need to be filled, including: a) the development of energy storage in China; b) role of energy storage in different application scenarios of the power system; c) analysis and discussion on the business model of energy storage in China.

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 does independent energy storage make money?

It can earn profits from the peak-valley price difference on the power generation side and give the energy storage power generation side capacity electricity fees. The revenue sources of independent energy storage are part of the ancillary service market model and part of the new energy negotiated lease model.

Where is energy storage used?

It is mainly used in power transmission and distribution systems with loads close to the equipment capacity. The energy storage is installed downstream of the power transmission and distribution equipment that originally needs to be upgraded to delay or avoid capacity expansion.

How can energy storage improve time-of-use electricity price management?

On the user side, energy storage can manage the user's time-of-use electricity price, manage capacity costs, and improve power quality. These three application scenarios are integrated with each other. When users build energy storage for time-of-use electricity price management, they also reduce load and capacity cost management.

Who pays the energy storage power station lease fee?

The grid company pays the energy storage power station lease fee. The lease fee enters the cost of the grid company and is borne by the grid operating enterprise. And the ownership and operation rights of the energy storage power station are separated. Fig. 4. Flow chart of negotiated lease model.
