摘　　要：综合能源系统包含的设备和负荷类型众多,设备之间的耦合方式多样,在实际综合园区建设过程中,对不同供能方式的经济性和可靠性评估显得尤为重要。首先,通过构建冷热供能系统的时序模型、耦合设备和储能装置的通用模型,并结合时间约束Petri网基本建模原理,建立了系统的运行优化模型;然后,对系统中元件两状态模型进行分析,建立系统的状态空间模型;并通过系统状态进行随机抽样并计算相应的供能可靠性指标。最后,通过对含有储热、储电、储气等多能存储的实际综合园区进行算例分析,评估不同运行方式下多能源系统的可靠性和经济性,从而为实际园区建设提供理论分析依据。The integrated energy system(IES) contains many types of equipment and load, and the coupling modes between the equipment are varied. In the construction process of actual integrated park, it is very important to evaluate the economy and reliability of different energy supply modes. Firstly, this paper establishes an operation optimization model of the IES system according to the basic modeling principle of the time constraint Petri net(TCPN), and by constructing the timing model of the cool and heat energy supply system, the general model coupling equipment and the energy storage devices. And then, the two-state model of the components in the system is analyzed to establish the system state space model. The corresponding energy supply reliability indexes are calculated by random sampling of the system state. Finally, the reliability and economy of multi-energy system under different operation modes are evaluated through case study of an actual integrated park with multi-energy storage, such as heat storage, electricity storage and gas storage.
