Abstract：The Regional Integrated Energy System can realize the optimal operation,coordinated management and complementarity of various heterogeneous energy subsystems through the coupling of multiple energy sources in the region.However,uncertainties like random fluctuations in energy consumption and fluctuations in the operating status of distributed energy equipment have increased the difficulty of operation optimization.Therefore,this paper focuses on the dynamic output of the equipment,and proposes a triple-stage operation optimization model of Regional Integrated Energy System.Based on the previous operation optimization mode and the dynamic output model of distributed energy equipment,the model proposes two optimization modes,loop optimization and monitoring optimization,for random fluctuations in load under routine operation scenarios and equipment operation state fluctuations under emergency response scenarios,and put forward the optimization process and optimization goals in different stage.Finally,with the actual operation of a park in Nanjing,China taken as an example,based on the day-ahead optimization,this paper made a comparative analysis of the loop optimization under routine operation scenarios and the monitoring optimization effect under emergency response scenarios to prove the triple-stage operation optimization model under different scenarios.It is proved to be an effective method for the operation optimization of the Regional Integrated Energy System.
