The invention provides an attack risk coupling modeling method for power intranet terminal equipment, which comprises the following steps of: establishing a physical system model based on node heterogeneity of a physical system; establishing an information system model based on node heterogeneity of the information system; establishing an information physical coupling model according to the dependency relationship between the nodes; and optimizing the cascade information physical coupling model. On the basis of the complex network theory, the information system and physical system node characterization method is provided by comprehensively considering the static characteristics and node heterogeneity of the complex network. And meanwhile, a dual-network coupling mode is designed by adopting real data, and node distribution is performed according to an actual coupling relationship. And on the basis of correctly reflecting the actual operation characteristics of the power CPS network, the power CPS complex network is simplified to the greatest extent, so that the model better conforms to the actual operation condition of the power information physical system.
Description
technical field [0001] The invention relates to the technical field of power system risk control, in particular to an attack risk coupling modeling method for terminal equipment in a power intranet considering heterogeneity of terminal equipment nodes. Background technique [0002] With the continuous improvement of the intelligence level of the power grid, the proposal and continuous development of the energy Internet strategy, due to the high coupling between the physical system and the information system in the process of power grid construction, a new type of power information physical fusion system ( Cyber Physical Systems, CPS). Although the power CPS has improved the types of data collection, improved communication efficiency, and enriched the control capabilities of the system, it has also introduced new forms of reliability risk and risk communication, and the cyber-physical fusion system has become a risk communication channel. In an interdependent coupling netw...
