With the continuous development of the new-type power system

the proportion of new energy sources is constantly increasing

and the dynamic characteristics of the power system have undergone significant changes. The traditional scenario-based analysis mode is increasingly mismatched and poses greater risks. The response-driven analysis and control mode is an important support for ensuring the safe and stable operation of the new-type power system. As a bridge connecting response information and the dynamic characteristics of complex nonlinear systems

the Koopman Operator enables the analysis of complex features of large power grids based on measured data

providing a new research framework for the response-driven stability control mode. This paper first summarizes the concepts

properties

and calculation methods of the Koopman Operator. On this basis

it categorically reviews the research work and key technical evaluations of domestic and foreign scholars from three application scenarios: power system perception

evaluation

and control. Finally

in combination with the demands and challenges of the response-driven stability control mode in the new-type power system

the application of the Koopman Operator in the research of safety and stability of the new-type power system is discussed.
