Research On Cross Space Risk Model And Simulation In Energy Internet Based On Complex Network

With the depletion of fossil fuels and the aggravation of environmental problems,renewable energy is becoming the main force in the energy industry.What followed was the era of the "Internet of Energy".It was a product of the deep integration of energy and information technology.The face of such a complex and huge energy system,the risk should not be underestimated,and to study the energy Internet risks,we must consider the physical space and cyber space for the deep integration and complex interaction problems,that is,Energy Internet Cyber-Physical System(ECPS),as the research object.At present,the study on risk of ECPS stays within a single space and involves less cross-space transmission of risk.Therefore,cross-space risk transmission of ECPS is an inherent requirement and an inevitable trend of energy Internet development.Combined with the theory of complex networks,this paper focuses on the topological level of energy Internet information and physical across the space risk transfer conducted a systematic study.First of all,the dissertation introduces the connotation and characteristics of energy internet in detail,and briefly analyzes the challenges faced by ECPS.Based on this,analyzes the key of energy Internet information physics fusion system based on analogy information internet Equipment,including energy router,energy exchanger and so on,and deeply analyzes the architecture of ECPS.Based on this architecture,ECPS is hierarchically layered so as to draw on the idea of object-oriented and divide ECPS into cyber space and physical space,the risk transfer research of ECPS is transformed into the risk transfer of cyber space and physical space.The topology model is constructed through the characterization of cyber space and physical space.Then,based on the ECPS topology model,the ECPS cross-space transfer structure is proposed,and the interaction path and interaction coefficient are defined.At the same time,an ECPS cross-space transfer model is established.The model quantitatively describes the risk transfer and risk impact assessment.Through the example,the various steps and calculation methods of the model are understood in detail,and through the discussion of the result,the characteristics of the ECPS risks transfer across space are analyzed.Finally,the dissertation's model is applied to a system.By analyzing the requirements and functional structure of the simulation system,the ECPS simulation system for cross-space risk transfer is designed and implemented,which will provide reference for future research.
