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

Abstract

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.
