Abstract：With the vigorous development of new energy technologies, the traditional grid frequency control is facing an increasingly severe test. There is good development space for the lithium-ion battery energy storage system helps the thermal power unit to participate in frequency adjustment. In this paper, the application scenario is the lithium-ion battery energy storage system assists the thermal power unit to participate in the automatic generation control (AGC) auxiliary service. And the evaluation compensation algorithm of the AGC auxiliary service is compiled according to the "two rules". A comparatively conservative but reliable battery energy decay model was established through the decay experiment. About the control strategy, the SOE trend control strategy based on Logistic function and the economic strategy based on evaluation index were built. Operating conditions is used to be simulated to fit the daily adjustment model of the energy storage system. Finally, a project economic analysis is conducted for the project's life cycle net income, investment payback period and return on investment. This paper obtains the initial energy allocation scheme of the energy storage system by evaluating the payback period and return on investment, and provides a sensitivity analysis of possible policy updates and market changes. We can obtain more rigorous and reliable investment solutions having strong compatibility with policy and market changes by using this economic model.
