Investigating early warning signs of oscillatory instability in simulated phasor measurements
Goodarz Ghanavati, Paul D. H. Hines, Taras I. Lakoba
This paper shows that the variance of load bus voltage magnitude in a small power system test case increases monotonically as the system approaches a Hopf bifurcation. This propert…
Understanding early indicators of critical transitions in power systems from autocorrelation functions
Goodarz Ghanavati, Paul D. H. Hines, Taras I. Lakoba +1
Many dynamical systems, including power systems, recover from perturbations more slowly as they approach critical transitions---a phenomenon known as critical slowing down. If the…
Calculation of the Autocorrelation Function of the Stochastic Single Machine Infinite Bus System
Goodarz Ghanavati, Paul D. H. Hines, Taras Lakoba +1
Critical slowing down (CSD) is the phenomenon in which a system recovers more slowly from small perturbations. CSD, as evidenced by increasing signal variance and autocorrelation,…
Changes in Cascading Failure Risk with Generator Dispatch Method and System Load Level
Pooya Rezaei, Paul D. H. Hines
Industry reliability rules increasingly require utilities to study and mitigate cascading failure risk in their system. Motivated by this, this paper describes how cascading failur…
Transdisciplinary electric power grid science
Charles D. Brummitt, Paul D. H. Hines, Ian Dobson +2
The 20th-century engineering feat that most improved the quality of human life, the electric power system, now faces discipline-spanning challenges that threaten that distinction.…
