Abstract In this paper, how to improve the utilization efficiency of battery energy storage(BES) emergency reserve in the on-grid operation of integrated energy system(IES) is studied, and a method for optimal utilization of BES emergency reserve based on risk quantification and demand-side response is proposed. Firstly, the energy model of IES equipment in a battery production park is constructed. Secondly, considering the probability of unplanned off-grid and the loss of important load, the off-grid risk is quantified. On this basis, considering the risk of off-grid and the income of on-grid, and considering the demand side response of the battery production park, the IES optimal scheduling model based on risk quantification and demand side response is constructed, which is transformed into mixed integer linear programming model by linearization. Considering the prediction deviation, MPC rolling correction is used to track the calculated tie line power and BES reserve day ahead plan value in real time. Finally, the simulation results show that the proposed method can improve the economy of IES operation with less risk, and has good practicability and economy.

Key words： Risk quantification battery energy storage (BES) emergency reserve demand side response model predictive control (MPC)
