Introduction  With the advancement of carbon peak and neutrality, the new power system will gradually form. The new power system is mainly composed of wind power and photovoltaic power generation. Due to the volatility, randomness and intermittence of wind power and photovoltaic power generation, the "real-time balance and stable operation" necessary for the power system will face unprecedented problems. To solve this problem, the fundamental way is to scale, market-oriented energy storage technology.

  Method  Based on China's energy development situation, energy storage solutions were emphatically discussed, and six technical routes of the two types of energy storage were analyzed from four aspects of technical feasibility, market feasibility, resource satisfaction rate and scale prospect.

  Results  From the current technical level, only pumped storage, chemical energy storage and hydrogen energy storage have the technical feasibility, economic marketization and prospect of scale. The energy storage measures that can be widely used are chemical battery energy storage and pumped storage, and the three application scenarios of pumped storage power station, chemical battery energy storage power station and power exchange station. In the face of the problem of real-time balance of supply and demand in the "real-time balance and stable operation", the solution should be based on the combination of pumped storage power station, chemical energy storage power station, switching power station and wind-solar redundant installed machine, and other energy storage and adjustment measures should be supplemented.

  Conclusion  The new energy and energy storage industry will usher in an era of rapid development. The new power system energy storage solution proposed in this paper has important theoretical significance for the realization of the carbon peak and neutrality.
