摘要针对综合能源系统并网运行中如何提高储能事故备用容量利用效率的问题,提出一种基于风险量化与需求侧响应的储能事故备用优化利用方法。首先,构建某电池生产园区综合能源系统（IES）设备能量模型;然后,综合考虑非计划脱网概率以及重要负荷损失将脱网风险进行量化;在此基础上,兼顾脱网风险与并网收益,同时考虑园区需求侧响应,构建基于风险量化与需求侧响应的IES优化调度模型,通过线性化处理将其转换为混合整数线性规划模型进行求解,考虑到预测偏差,通过MPC滚动修正,实时跟踪求解出的联络线功率与电储能备用日前计划值;最后,通过仿真验证,所提方法能够在承担较小风险的情况下提高IES运行的经济性,具有很好的实用性和经济性。

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)
