Security Analysis of Integrated Energy System under Complex Network

Abstract

Currently, the power system is being transformed into a new generation of clean and low-carbon integrated energy system. Not only the intermittent and random nature of renewable energy output will affect the normal operation of integrated energy power system, but also the disturbance caused by extreme events to individual energy systems may trigger chain failures within the scope of integrated energy power system. However, the complex coupling relationship of integrated energy systems has been a difficult problem for safety analysis, and little research has been done in this area. Fortunately, the successful application of complex network theory in other fields provides a reference for this purpose. Therefore, this paper first models the integrated energy system based on complex network theory, then analyzes the network characteristics of the integrated energy system to illustrate the feasibility of using complex network related theory to study the safety of the integrated energy system, and finally verifies the possibility of risk transmission across space in the integrated energy system by means of the dependency model. The results of the paper can provide theoretical support for the study of the security problems in integrated energy systems under complex network theory.
