Abstract

The disclosure provides a power system vulnerability analysis method in consideration of information physical joint attack. When the primary equipment (generator, transformer, transmission line and the like) of the grip in a certain area is physically destroyed, stops operation, and causes changes in the topological structure of the grid, problems such as power flow transfer, branch out-of-limit power and power imbalance of the power system possibly occurs. If the information system suffers an information attack at this time, it is determined that a power dispatching center loses an optimization adjustment capability, the grid proportionally adjusts power generation and consumption power to ensure the power balance, and the out-of-limit branch is cut off by a relay protection device. If the information system does not suffer an information attack, after the destroyed equipment is shut down, the power dispatching center performs optimization with the minimum load loss as a goal, and performs adjustment and control from the power supply side and the load side to eliminate the branch out-of-limit power while ensuring the power balance of the grid.

Description

technical field [0001] The present disclosure relates to a power system vulnerability analysis method considering cyber-physical joint attack. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] Smart grid is a composite system composed of information virtual network and physical entity network, which is characterized by close coordination between information system and physical system. With the continuous development of the smart grid, the degree of automation of the power system continues to increase, the number of various measurement calculations and decision-making control units in the power grid has greatly increased, and the scale of the power information network has become larger and larger. The power system has developed into a complex system with deep integration of information and physics, and its stable operation cannot be separat...
