Introduction   Under the goal of "carbon peak and neutrality" goal, the new power system with new energy as the main body has attached great importance to energy storage on the "source-grid-load" side. Exploring the energy storage business model and cost recovery mechanism, and improving the energy storage related market rules and supporting policy mechanism are of great significance to promote the sustainable development of energy storage, the construction of new power system and the realization of the "carbon peak and neutrality" goal.

    Method   The source of energy storage income is calculated by using various methods such as operation period pricing method, cost + reasonable income and power load loss value based on energy storage pricing at home and abroad.

    Result   The application scenarios, business models and cost recovery mechanism of new energy storage on the "source-grid-load" side were sorted out, and the existing problems and policy suggestions were summarized.

    Conclusion   The research results are of good operability and reference value, and can provide useful reference for the development and policy-making of energy storage.
