Embodiment Construction
[0062] The present invention will be further described below. The following embodiments are only used to illustrate the technical solutions of the present invention more clearly, and cannot be used to limit the protection scope of the present invention.
[0063] The embodiment of the present invention provides a CPS safety assessment method considering the influence of information in failure recovery, and the specific implementation process is as follows:
[0064] Step 1: Carry out the hierarchical structure division of the distribution network CPS and establish the distribution network CPS correlation matrix model.
[0065] The hierarchical division of the distribution network CPS refers to the abstraction of the distribution network CPS unit into a physical entity layer, an information-physical coupling layer and an information system layer, corresponding to the physical network, communication network / secondary equipment network and control decision unit respectively.
[0066] Among...

The invention discloses a CPS safety evaluation method and device considering information influence in fault recovery, and the method comprises the steps: carrying out the modeling of an information system and a physical system of a CPS power distribution network through employing an incidence matrix method for a research object of the power distribution network CPS; respectively constructing an information anticipated fault and a physical anticipated fault, and analyzing the influence of the information system on the physical system; finally proposing a safety evaluation index of the power distribution network CPS, and carrying out safety evaluation. By constructing a power distribution network CPS hierarchical structure and utilizing an incidence matrix modeling method, the topological association and logic association relationships among systems of the power distribution network CPS can be visually reflected, and meanwhile, the coupling characteristics of the power distribution network CPS information physics can be accurately simulated. The invention provides the power distribution network CPS security evaluation method based on an anticipated fault set, and the method can achieve the quantitative evaluation of the security of the power distribution network CPS.
Description
Technical field [0001] The invention relates to a CPS safety evaluation method and device considering the influence of information in failure recovery, and belongs to the technical field of power distribution network safety evaluation. Background technique [0002] With the widespread access of controllable loads such as smart home appliances, electric vehicles, controllable industrial loads, distributed power sources, and distributed power sources, as well as the application of technologies such as power distribution automation and demand-side response, a variety of power grid control has been provided. Means and resources. However, current factors such as distributed power generation, flexible load and intelligent control enhance the observability and controllability of the power system, but also bring about the problem of how to highly integrate energy flow, data flow and business flow, so as to realize the safety and security of the distribution network. Efficient and reliab...
