This paper presents a new method for transient stability assessment of power systems using kernel principal component analysis (KPCA) and Gaussian process (GP). Considering the possible real-time information provided by PMU, a group of system-level classification features are firstly extracted from the power system operation condition to construct the original feature set. Then KPCA is used to ...

Transient stability assessment (TSA) has always been a fundamental means for ensuring the secure and stable operation of power systems. Due to integration new elements such as electronics, electric vehicles renewable generations, dynamic characteristics systems are becoming more complex, which makes TSA an increasingly urgent task. Since traditional time-domain simulations direct method cannot ...
