Abstract: With the maturity of energy storage technologies and rapid decline in cost, China's energy storage industry has developed rapidly, and the application of energy storage in power systems has gradually shifted from demonstration to commercialization phase. However, the energy storage industry is still in its early stage of development, and some problems still exist, such as the unclear development prospects, the unperfected standard systems, and the ill-defined business models and market mechanism. This paper reviews the status quo of China's energy storage development from the aspects of development scale, technological economy and industrial chain. Based on the coordinated planning theory of "generation-grid-load-storage", the prospect of medium and long term energy storage development are investigated from the macro layer, and relevant important issues are studied, such as the rational operation mode of energy storage and its relationship with new energy accommodation. And the key application issues of energy storage in generation side, grid side and user side are analyzed from the microscopic aspects, and related development strategies are studied. Relevant suggestions are put forward to provide support and reference for promoting the healthy development of China's energy storage industry.

Key words: power system, energy storage, new energy, generation-grid-load-storage, power planning, development prospects, market mechanism
