Description

Technical field

[0001] The present invention relates to the technical field of smart grid security risk assessment, in particular to a power grid security risk assessment method and model based on situational awareness. Background technique

[0002] Situational awareness technology was first used in aviation, aerospace, and other fields that require operators to quickly understand the surrounding situation, make correct decisions and operate. With the gradual maturity of theories and methods, it has developed into complex man-machine-environment systems such as electric power and medical treatment in recent years. . The most direct definition of situational awareness is to know what is happening around you, that is, to perceive, understand and predict the surrounding environment in time and space. The application of situational awareness technology to the power system refers to a series of actions in the grid environment where dispatchers acquire, understand, display and predict...
