Problems solved by technology

Due to the complexity of the grid situation, the current grid security risk assessment is mainly based on the expected accident set to establish a security risk assessment model and risk index analysis, which belongs to passive perception, cannot comprehensively understand the grid security situation from the overall time and space, and does not provide enough support for dispatchers to assist decision-making; and Due to the timeliness and separation of real-time, online, and offline data information processing, dispatchers can only obtain partial data and information, and cannot fully perceive the power system security risk situation in real time

Abstract

The invention provides a grid security risk assessment method and model based on situation awareness. Decision-making objectives of dispatchers serve as cores, situation awareness technology is applied to grid security risk assessment, active prospective grid situation awareness abilities and blackout security defense abilities of the dispatchers are greatly improved, the asset utilization rate of grids can be increased, and strong, economical, secure and superior objectives of the smart grids are achieved. The method includes the steps: firstly, perceiving grid situations; secondly, understanding the grid situations; thirdly, forecasting the grid situations.

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...
