Static Security Analysis of Park-level Agricultural Energy Internet Considering Spatial Coupling

空间耦合是农业园区能源互联网的重要特征之一,会导致光伏发电和农业生产之间形成一种争光现象,这对设施农业环境和园区能源系统的协同安全提出了挑战。针对上述挑战,该文首先构建一种考虑空间耦合与能源耦合交互影响的农业能源互联网模型,以此来刻画设施农业环境与能源系统运行状态之间的相互影响。其次考虑能源系统运行和农业生产的双重约束,给出能源安全指标、农业安全指标以及安全分析流程。最后以某个实际电–热耦合多能流系统为仿真对象,分析空间耦合度对园区能源系统安全运行的影响,给出特定环境下空间耦合度的安全边界值。

Spatial coupling, one of the important characteristics of a park-level agricultural energy internet, may result in a competition for light between the photovoltaic power generation and the agricultural production, which poses a challenge to the coordinated security of the facility agricultural environment and the park energy system. In response to the above-mentioned challenges, this paper first builds an agricultural energy internet model that considers the interaction of spatial coupling and energy coupling to characterize the interaction between the facility agricultural environment and the operating state of the energy system. Secondly, considering the dual constraints of the energy system operation and the agricultural production, the energy security indicators, the agricultural security indicators and the safety analysis procedures are given. Finally, taking an actual electric-thermal coupling multi-energy system as the simulation object, the influence of the spatial coupling degree on the safe operation of the park energy system is analyzed, and the safety boundary value of the spatial coupling degree in a specific environment is given.
