Energy storage plays a role in timing adjustment for power application

and energy storage technology is gradually improved

its application scenarios are also gradually diversified. Under the "integration of windphotovoltaic-water-fire-storage" and "integration of source-network-load-storage"("two integrations")

the flexible adjustment role of energy storage will be fully played

and the energy storage is expected to usher in a wider development space. This paper firstly reviews the relevant policies in the new energy field and the general situation of the construction plan of "two integrations"

analyzes the flexibility and economy of energy storage under the "two integrations"

then studies the energy storage planning under the "two integrations" and explores the commercialization application of "two integrations". Finally

several suggestions are put forward

such as the energy storage facilities should be configured according to local conditions

the income of energy storage should be diversified

and the business model of energy storage should be improved

which provides a certain reference significance for the development trend of energy storage in the future.
