Energy Storage Business Model and Application Scenario Analysis Based on Large-Scale Renewable Energy Access

As the core support for the development of renewable energy, energy storage is conducive to improving the power grid ability to consume and control a high proportion of renewable energy. It improves the penetration rate of renewable energy. In this paper, the typical application mode of energy storage from the power generation side, the power grid side, and the user side is analyzed first. Then, the economic comprehensive evaluation method of the energy storage full life cycle is put forward, which uses the internal rate of return method to evaluate the energy storage system investment subject in the current technology const investment profitability. Finally, according to the economic calculation, the applicable business mode of energy storage is proposed. The effectiveness and adaptability of the proposed analysis method are verified by different energy storage application scenarios.
