Online emergency control to suppress frequency oscillations based on damping evaluation using dissipation energy flow
International Journal of Electrical Power & Energy Systems(2018)
Abstract
•An online emergency control approach to suppress frequency oscillations is proposed.•The damping of prime movers is evaluated using the dissipation energy flow.•Primary frequency regulations of units with lowest negative damping are tripped.•Proposed approach is measurement-based and online applicable.
