But the existing energy storage technology standards in China are not perfect, and a standardization system for the whole industry has not been established, let alone testing and approving products according to relevant standards .
Energy storage assists wind farms with the storage and transportation of electrical energy. Energy storage projects in North China are currently the most in China. Due to the geographical environment, the power grid in Northwest China cannot supply power to all regions.
The context of the energy storage industry in China is shown in Fig. 1. Fig. 1. The context of the energy storage industry in China [, , ]. As can be seen from Fig. 1, energy storage has achieved a transformation from scientific research to large-scale application within 20 years.
Energy storage demand in China is without a doubt. Currently, China is carrying out the urbanization of centrality, intelligence, green and low carbon. Among them, the application of DG, smart micro-grid, EV, and the intelligent management of power grid all need energy storage , , , , .
Energy storage projects in North China are currently the most in China. Due to the geographical environment, the power grid in Northwest China cannot supply power to all regions. Provide electricity to the people of the region through off-grid distributed generation and energy storage systems.
It also introduces the application scenarios of energy storage on the power generation side, transmission and distribution side, user side and microgrid of the power system in detail. Section 3 introduces six business models of energy storage in China and analyzes their practical applications.
