Embodiment Construction

[0054] The present invention will be further described below in conjunction with the accompanying drawings.

[0055] Such as figure 1 As shown, it is a schematic flow diagram of a method for conflict resolution of an electric power industrial control system cooperative defense strategy provided by a specific embodiment of the present invention, and the method includes the following steps:

[0056] Step 1, initialize and input the basic information of the security policy in the electric power industrial control system.

[0057] The security policy includes: an intra-domain self-defense policy and a cross-domain cooperative defense policy.

[0058] The construction of the intra-domain self-defense strategy is based on the relatively independent local response and defense of each autonomous domain. The main station, substation, factory station, etc. constitute their own autonomous domains; the intra-domain self-defense strategy includes: host local blocking, autonomous domain bl...

Abstract

The invention discloses a collaborative defense strategy conflict resolution method and system in the technical field of electric power engineering, and aims to solve the problems that a conflict resolution method based on priority is poor in flexibility and a conflict resolution method based on a combination algorithm cannot effectively solve strategy conflicts inherent in strategies and caused by improper strategy making in the prior art. The method comprises the following steps of establishing a security policy general conflict resolution method table according to security policy prioritiesand a security policy hidden relation table, and conducting feature extraction on security policy conflict information of the defense; matching the extracted features with a defense security policy general conflict resolution method table; and according to a matching result, extracting an adaptive resolution rule in the collaborative defense security policy general conflict resolution method table to perform conflict resolution.

Description

technical field [0001] The invention relates to a method and system for conflict resolution of cooperative defense strategies, belonging to the technical field of electric power engineering. Background technique [0002] With the rapid development of global energy Internet construction, UHV power grid and distributed energy, electric vehicles, controllable users, micro-grids, etc. have the ability to interact with the grid in two directions, and new loads with dual characteristics of "source" and "load". proportion showed a rising trend. As the spatio-temporal distribution characteristics of the power grid become more and more complex, the importance and urgency of the interaction and collaborative control among the power grid, power supply and users are also increasing. [0003] In the context of source-grid-load interaction, industrial control systems widely distributed in power supply companies, power plants, and substations continue to extend to the new energy power gen...
