Summary:This study reports an approach of selecting an effective feedback signal to damp out electromechanical oscillations in the power system under unpredictable supply and demand situation. The idea of minimum variance of the modal residue has been utilised to select a signal which is very effective over a large number of operating conditions. A minimal variation of residue results in minimal deviation in damping performance from the desired level. The effectiveness of the method is demonstrated in a 16-machine, 68-bus NETS-NYPS test system and 46-machine, 190-bus practical Mexican interconnected system models.
