Embodiment Construction
[0068] The elasticity improvement strategy of the electric power cyber-physical fusion system formulates the line and node strengthening transformation plan through the upper-level power grid protection model. This model conducts the dynamic attack and defense game of electric power CPS, and finally can obtain the line modification plan and node strengthening plan that minimize the expected profit of the attacker. Power grid resilience is divided into three stages: "resistance and absorption", "response and adaptation" and "recovery". It can optimize the system performance in the "resistance and absorption" stage and improve the disaster recovery capability of the system. When the system response time does not change with the fault change and the recovery speed of different components is the same, the resilience of the power system in response to catastrophic attacks can be improved.

The invention relates to a method for solving the elastic improvement strategy of the electric power information physics fusion system. The line and node reinforcement transformation plan is formulated through the upper-level power grid protection model, the middle-level power grid attack model is intended to maximize system losses, and the bottom-level power grid resistance model is aimed at minimizing system losses. Minimization, through the traversal method to carry out the power dynamic attack and defense game on the model, and finally the line modification plan and node strengthening plan that minimize the expected income of the attacker can be obtained. Power grid resilience is divided into three stages: "resistance and absorption", "response and adaptation" and "recovery". It can optimize the system performance in the "resistance and absorption" stage, and improve the disaster recovery capability of the system. When the system response time does not change with the fault change and the recovery speed of different components is the same, the resilience of the power system in response to catastrophic attacks can be improved.
Description
technical field [0001] The invention relates to a cross field of mathematical calculation and information security, in particular to a method for solving an elastic promotion strategy of a power information physics fusion system based on a dynamic attack and defense game. Background technique [0002] At the 1st China Internet Security Leaders Summit held in Beijing, the executive deputy director of the Informatization Committee of the Chinese Society for Electrical Engineering expressed concern about the security of the power CPS system, saying that "if the US power grid suffers from cyber attacks, the most serious losses will exceed 1 trillion dollars". Tang Yi (Tang Yi, Chen Qian, Li Mengya, et al. A review of research on cyber attacks in the environment of power cyber-physical fusion systems [J]. Electric Power System Automation, 2016, 40(17): 59-69.) and others published an article pointing out that The modern power system is no longer only adjusted and controlled acco...
