摘　　要：综合能源系统作为能源互联网的重要物理载体,对于提高区域综合能效、保障用能安全以及实现节能减排具有重要意义。建立一种基于全生命周期的园区型综合能源系统分期协同规划模型。首先,根据综合能源设备的安装容量是否连续,将设备分为离散和连续设备,分别对其配置和运行约束进行提炼和统一化表示;然后,以整个项目周期为优化时间尺度,通过引入设备选型和运行决策变量,对设备安装年份与当前剩余寿命之间的关系进行数学建模;最后,考虑名义利率与通货膨胀率等因素的影响,构建以经济性最优为目标,计及投资成本、运行成本与设备残值收入的目标函数。采用混合整数线性规划技术对模型进行求解。4种场景的测试结果表明:相比传统的单阶段规划,考虑设备替换的分期协同规划可以减少14.76%的设备投资。在引入储热装置和弃热约束后,热电耦合系统运行成本可以进一步减少11.78%。As an important physical carrier of energy internet,an integrated energy system is of great significance for improving regional comprehensive energy efficiency,ensuring energy safety and realizing energy conservation and emission reduction.In this paper,a staged collaborative planning model of the park-type integrated energy system is built on the basis of the whole life cycle.Firstly,regarding the continuation of equipment installation capacity,the equipment is divided into discrete and continuous groups,and their configuration and operation constraints are refined and unified respectively.Then,with the whole project cycle as the optimization time scale,the relationship between the equipment installation year and the current remaining life is modeled by introducing the equipment selection and operation decision variables.Finally,considering the influence of economic factors such as nominal interest rates and inflation rates,an objective function,involving investment costs,operating costs,and equipment residual value income,is constructed,with the optimal economical performance as the goal.The mixed integer linear programming technique is used to solve the model.The test results of the four scenarios show that the staged collaborative planning considering equipment replacement can cut the equipment investment by 14.76%compared to the traditional single-stage planning.After the introduction of heat storage devices and heat abandonment constraints,the operating cost of the thermoelectric coupled system can be further reduced by 11.78%.
