DBSCAN-based coherency identification of generators using complex wavelet transform

DBSCAN-based coherency identification of generators using complex wavelet transform

The coherency of generators in a multi-machine power system is identified by determining the instantaneous phase difference between their rotor angles using a complex wavelet transform. A new phase difference matrix is proposed that represents the relative phase difference between the dominant frequ...
