Driven by the "30·60" national strategy, power system will develop towards the new type of power system rapidly which dominated by new energy resources. The access of large-scale of new energy resources as well as the in-depth exploration of resources in user side have made it difficult for traditional dispatching methods to support the safe and stable power supply. New energy storage, as an adjustable and flexible equipment that has flourished in recent years, is useful for filling the growing gap in regulation capacity of power grid and consuming renewable energy effectively. First of all, this article elaborates on the significant energy storage categories and their own advantages. On this basis, analyze the technical application and profit path of five emerging scenarios in power supply side and consumption side, including new energy resource configurating energy storage, thermal power plant equipped with energy storage, 5G base station application, electric vehicles, virtual power plant. And then the Qinghai province demonstration is used as an example to discuss the business operation model of shared energy storage, and some suggestions are proposed to increase the return on investment for operators from optimizing quota and multiple delivery. Finally, briefly discusses the development of new energy storage in the long-term year.
