Transient Stability of Power Systems is a monograph devoted to a
hybrid-direct temporal method called SIME (for Single Machine
Equivalent). SIME processes temporal information about the
multimachine system dynamics to assess and control any type of
transient instabilities under any type and model of power systems.
Two approaches may be distinguished depending upon the source of
information used: Preventative SIME' which relies on a time-domain
program to simulate anticipated contingencies, and Emergency SIME'
which uses real-time measurements. Preventative SIME mainly
comprises two techniques: contingency filtering, ranking, and
assessment; and (simultaneous) stabilization of harmful
contingencies. The resulting preventative transient stability
assessment and control (TSA&C) software can be used in all
application contexts of transient stability studies. In a control
center, for instance, its computational performances enable it to
cope with very stringent requirements of real-time operation.
Besides, interfacing SIME with an OPF algorithm allows combining
transient stability constraints with specifics of the liberalized
electricity market. Emergency SIME is a novel closed-loop control
technique which contains the transient instabilities caused by
contingencies' actual occurrence. It relies on real-time
measurements to predict (the size of) instability and, accordingly,
to design and trigger control actions able to impede system loss of
synchronism. Emergency SIME is particularly suitable for protecting
important generation sites and can complement preventative SIME.
Both approaches rely on the same principles and basic software
which yields a comprehensive and unified approach toTSA&C. The
design of near optimal control techniques is a major asset of this
software. This book provides extensive illustrations on a variety
of power systems ranging from a simple 3-machine test system to
real-world power systems comprising up to 627 generators and 4112
busses. Transient Stability of Power Systems will be especially
helpful to researchers, utility engineers, and software designers
and developers who are developing various types of transient
stability software packages.
