What is the energy storage system?

The energy storage system includes 1×5 MW×2 h LiB, 1×2 MW×2 h VRFB. And the wind power of 99 MW had been put into operation in August 2012. The system is connected with the 35 kV bus. Through intelligent control, the system stores and releases power according to the coordinating with wind power.

What factors influence the business model of energy storage?

The factors that influence the business model include peak–valley price difference, frequency modulation ratio of the market, as well as the investment cost of energy storage, so this paper will discuss from the following perspectives.

Is energy storage a precondition for large-scale integration and consumption?

So to speak, energy storage is the precondition of large-scale integration and consumption of RES. However, China's energy storage industry is at the exploration stage and far from commercialization. This restricts the development of RES to certain extent. For this reason, this paper will concentrate on China's energy storage industry.

What is a good technical standard for energy storage?

A sound technical standard, covering all aspects of energy storage industry chain, is a prerequisite to achieve industrial scale and engineering applications.

Does energy storage industry need a policy guidance?

Sungrow Power Supply Co., Ltd.: energy storage industry needs the policy guidance urgently. Machinery & Electronics Business; 2015-6-22: A06. Policy and innovation are key factors for the development of energy storage technology. China Electric Power News; 2016-4-28: 008. Lin Boqiang.

What is the difference between energy storage capacity configuration and online storage?

In the three scenarios, with the distinction between the two methods of energy storage capacity configuration, it is clear that the storage capacity of the energy with the surplus power online presents far less than with surplus power offline in local equilibrium.
