Abstract
Online security and stability calculation and analysis technologies provide crucial support for the accurate perception of real-time grid operation status and correct decision-making for the power dispatching sector.With the increasingly complex and stochastic dynamic characteristics of new power systems,traditional online security and stability analysis systems based on steady-state and asynchronous measurement data have shown deficiencies in real-time and accuracy.In contrast,the new generation of online security and stability analysis technology based on dynamic and synchronous phasor measurement data has attracted attention from research and engineering communities both domestically and internationally.In this context,this paper reviews the key technologies and bottlenecks involved in the existing online security and stability calculation and analysis systems,focusing on real-time state perception,dynamic parameter identification,and online stability assessment as core components.Furthermore,the overall framework and possible future research directions for the next generation of online security and stability computation and analysis systems are proposed,with the aim of providing reliable technical support for the safe and stable operation of new power systems.
