| 摘 要： | 能源互联网呈现物理信息深度融合的趋势,为电力系统管理研究定义了新的研究框架。作为一个先进的复杂系统,能源互联网信息物理系统(Energy Internet Cyber-Physical System,ECPS)在其发展过程中面临着一些新的挑战,其中一个就是耦合结构下的风险管理。本文结合复杂网络理论和风险传递理论,着重在拓扑层面分析了ECPS跨空间交互机理,并在此基础上定义了交互路径和交互系数;接着建立了ECPS跨空间风险传递模型,量化描述了风险的传递和演化过程,并进行了风险影响评估;最后,通过仿真实验分析了三种不同交互系数节点故障的风险传递过程和不同攻击模式下系统的崩溃过程。对仿真结果的讨论阐述了能源互联网风险跨空间传递的特点,为更深入地研究ECPS的风险管理提供了参考。

| Abstract: | The energy Internet presents a trend of deep integration of physics and information, defining a new research framework for power system management research. As an advanced complex system, Energy Internet Cyber-Physical System(ECPS)faces some new challenges during the development, one of which is risk management under the coupling structure. Combining complex network theory and risk transfer theory, this paper focuses on the analysis of ECPS cross-space interaction mechanism from the perspective of topology. Based on this, the interaction path and interaction coefficient are defined. Then the ECPS cross-space risk transfer model is established to quantitatively describe the process of risk transfer and evolution, and the risk impact assessment is carried out. Finally, the risk transfer process of three types of nodes with different interaction coefficients and the crash progress of the system under different attack modes are analyzed through simulation experiments. The discussion of simulation results illustrates the characteristics of energy Internet cross-space risk transfer, which provides a reference for the further study of ECPS risk management. |
