Application and Challenge of Koopman Operator in New-type Power System
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.
