Query: Online Coherence Identification Using Dynamic Time Warping for
  Controlled Islanding   Controlled islanding is considered to be the last countermeasure to prevent
system-wide blackouts in case of cascading failures. It splits the system into
self-sustained islands to maintain transient stability at the expense of
possible loss of load. Generator coherence identification is critical to
controlled islanding scheme as it helps identify the optimal cut-set to
maintain system transient stability. This paper presents a novel approach for
online generator coherency identification using phasor measurement unit (PMU)
data and dynamic time warping (DTW). Results from the coherence identification
are used to further cluster non-generator buses using spectral clustering with
the objective of minimizing power flow disruption. The proposed approach is
validated and compared to existing methods on the IEEE 39-bus system, through
which its advantages are demonstrated.
