Research on Power Planning Considering Power Grid Security

The construction of smart grids will bring huge challenges and opportunities to the electric power industry. The safety of smart grids is more related to national security issues. The working principle of the traditional malicious data injection attack is to use the limitations of the bad data identification method in the state estimator, maliciously tampering with the measured value of the component, causing the control center to misjudge the current state of the power grid, and then causing the power system stability control measures to malfunction or refuse. This will affect the safe and stable operation of the power system. It can be seen that considering the complexity and importance of system state estimation, in the smart grid environment, analyzing the mechanism of malicious data injection attacks and studying the corresponding detection and prevention methods have very important theoretical and practical significance. Grid planning needs to be optimized urgently, and grid security issues should be taken seriously.
