摘　　要：区域综合能源系统在调度过程中面临着可再生能源出力的不确定因素,会给系统的安全稳定运行带来一定的风险。考虑可再生能源出力在时间上的连续性和随机性,建立了带有伊藤积分的区域综合能源系统连续随机调度优化模型。该模型聚合了以热电联产机组、燃气锅炉、风电机组、电储能和热储能的能源集线器作为供能单元,向区域内部的电热负荷供能。采用真实的算例对模型进行验证分析,算例结果表明:该模型能够给出一组连续的最优调度方案,从而为调度人员的正确决策提供有效支持。该方法能够快速得到目标函数区间,相比于蒙特卡洛模拟,大大提高了计算效率。The regional integrated energy system faces uncertain factors in the output of renewable energy in the dispatch process,which brings certain risks to the safe and stable operation of the system.Considering the continuity and randomness of renewable energy output in time,a continuous stochastic dispatching optimization model of regional integrated energy system with Ito integral is established.The model uses an energy hub that includes combined heating and power units,gas boilers,wind turbines,electric energy storage and thermal energy storage as the energy supply equipment to supply energy to the electricity and thermal loads in the area.A real calculation example is used to verify and analyze the model.The results of the calculation example show that the model can provide a set of continuous optimal scheduling schemes,thereby providing effective support for the dispatchers to make correct decisions.Moreover,this method can quickly obtain the objective function interval.Compared with Monte Carlo simulation,this method greatly improves the calculation efficiency.
