The safety and stability control device is a control device installed in a power plant or substation to ensure the stability of the power system in the event of major disturbances. It is used to achieve functions such as machine cutting, load cutting, speed reduction, emergency increase or decrease of DC power, and is an important facility for maintaining the safe and stable operation of the power system. The power grid security and stability control system (referred to as "security and stability system") protects a local or entire power system, and its widespread application builds the second line of defense for modern power grids. The complex network structure and operational characteristics of modern power grids, as well as the commissioning of various and large-scale safety control systems, make any misoperation or refusal of operation of the safety and stability system possible to disrupt the safety and stability of the power grid. Therefore, conducting evaluation of stability system control strategies and verifying the expected effects is particularly important for ensuring the safety of the power grid. The power grid safety and stability control system is a system composed of two or more safety and stability control devices of power plants connected through communication, used to achieve stable control of regional or larger power systems. It can generally be divided into control main stations, control sub stations, and execution stations
