Transient stability index for online stability assessment and contingency evaluation

International Journal of Electrical Power & Energy Systems, 1982
Abstract An online methodology is proposed for assessing the robustness of a power system from the point of view of transient stability, and a scalar expression, the transient stability index, is accordingly derived. The reliability and sensitivity of this index are tested by means of simulations for a number of power system cases. The index is shown

A domain adaptation‐based convolutional neural network incorporating data augmentation for power system dynamic security assessment

The Journal of Engineering
Recently, deep learning (DL) based dynamic security assessment (DSA) methods have been very successful. However, although a DSA model can be trained well for a specific topology, it often does not perform well for other topologies.
