Abstract

The coherent generator groups identified method was proposed via Empirical Mode Decomposition (EMD) and Stochastic Subspace Identification (SSI) method in this paper. Only the generator rotor speed gathered from the Wide Area Measurement System (WAMS) is used in the proposed method, and the detailed model and parameters of power system components are not needed. And the phase diagram obtained by using the SSI was employed in the proposed method to identify the coherent generator groups. At the end, the simulation was tested on the CEPRI system with 8-generator. The results of test system testify the efficiency of the proposed method.
