Abstract: Energy storage is a very important flexible regulation resource for the new power system, which can play an important role among the power source plants, power grid, and end users. The development of energy storage in China has entered a period of large-scale development. The key to making reasonable and economical use of energy storage is the planning and configuration method. On the basis of current research status for energy storage planning methods, this paper analyzes the impact of new changes on energy storage planning method, such as the diversification of energy storage investment and operators, the complexity of application scenarios and operation modes, and the diversification of energy storage technologies. Furthermore, this paper proposes the energy storage planning method in the renewable energy gathering area with consideration of time-space complementation and sharing mechanism, the collaborative planning method of energy storage with transmission and distribution systems under full market competition, and the planning method under the coexistence of multiple energy storage cooperation/competition with electricity, heat, and hydrogen on the user side. Finally, for the energy storage planning of the new power system, attention should be paid to the overall coordination of different development stages for power systems in the future, the influence of game mechanism promoted by diversification of energy storage investment and operation entities, and the transfer learning method of planning schemes under multi-scenarios and multi-objectives.
