Applying a Formula for Generator Redispatch to Damp Interarea Oscillations Using Synchrophasors

Sarai Mendoza-Armenta, Ian Dobson
2016 IEEE Transactions on Power Systems  
If an interarea oscillatory mode has insufficient damping, generator redispatch can be used to improve its damping. We explain and apply a new analytic formula for the modal sensitivity to rank the best pairs of generators to redispatch. The formula requires some dynamic power system data and we show how to obtain that data from synchrophasor measurements. The application of the formula to damp interarea modes is explained and illustrated with interarea modes of the New England 10-machine power
