Distributed power system stabiliser for multimachine power systems
IET Generation, Transmission & Distribution, 2019 Power system stabiliser (PSS) widely used to enhance the stability of power systems is based on the feedback of rotor speed error with respect to the rated value. However in many occasions, after the disturbances, it is desirable to re‐synchronise all generators first rather than to make all generators back to the rated 50/60 Hz immediately. This study
