  •   Introduction  Under the goal of carbon peaking and carbon neutralization, building a new power system has become a realistic path of electric power development. As a flexible regulatory resource, stored energy plays an important role in improving the efficiency of power grid operation and the new energy consumption. In order to improve the flexibility of the power system and promote the coordinated and efficient development of power source, power grid, load and energy storage, it is necessary to identify the role of stored energy in different scenarios in accordance with the characteristics of stored energy technology and the actual needs in all aspects of the power system.
      Method  Based on the development status of the stored energy industry, the application scenarios and development potential of different stored energy technologies were analyzed, and the strategies of stored energy configuration on the grid side, power supply side and user side were proposed. The impact of stored energy was studied from the perspectives of substation design, grid planning, power balance and new energy consumption.
      Result  From the perspective of the power grid side, stored energy can improve the power supply capacity of power grid and delay or replace the power grid investment; from the perspective of the power supply side, the access of stored energy has an impact on the power balance, and the consumption level of new energy can be improved by optimizing the configuration of stored energy.
      Conclusion  As a supporting technology for the development of new power systems, stored energy will play a greater role. The stored energy configuration strategy proposed in this paper can provide guidance for practical application.
