A Coherency Identification Method of Active Frequency Response Control Based on Support Vector Clustering for Bulk Power System

Energies, 2019
Active frequency response (AFR) control is needed in current power systems. To solve the over-frequency problems of generators connected to non-disturbed buses during the AFR control period, the generators should be clustered into coherent groups.
