In order to achieve online awareness of the transient stability of power systems, 10 different transient indicators that can be directly obtained or indirectly calculated using WAMS measurement data were chosen as original covariates for regression analysis of stability margins. Furthermore, feature covariates were consequently selected via a method called Nonparametric Independence Screening (NIS)...
Considering transient stability control measures for current power system is time consuming and difficult to apply online, a WAMS-based control strategy is presented. In the first, the data column provided by WAMS is used to obtain the future trajectory of each generator's power angle δ after fault by numerical processing. Then, a new idea of calculating disturbance power based on prediction is realized...
