This invention discloses a joint scheduling optimization system and method for energy storage and frequency regulation markets, considering the electrochemical-aging coupling characteristics of energy storage, and relates to the field of energy storage. The method simplifies the calculation formula for terminal voltage by ignoring the effect of capacitance in the equivalent circuit, and linearizes the relationship between the open-circuit voltage and state of charge, as well as the internal resistance characteristics of the energy storage system, thereby effectively reducing model complexity. Simultaneously, it utilizes sequential convex programming techniques to successively approximate the non-convex optimization problem, significantly improving solution efficiency and computational accuracy. This method not only accurately characterizes the dynamic behavior of energy storage systems under different scenarios but also provides a more operational optimization scheme for practical engineering applications. Furthermore, by linearizing the power constraints, the scalability and adaptability of the model are further enhanced, making it more suitable for the actual needs of multi-scenario joint scheduling.
