Transient Stability Assessment Using Energy Function Method.
Masters thesis, Indian Institute of Technology Hyderabad.
Abstract
There are numerous assumptions made to dene the stability of power system models.
Step-by-Step numerical integrations of power system models are used to simulate the
system dynamic behavior. This type of power system stability analysis is based on the
time-domain approach. The typical simulation period of post-fault system is 10s and can
go beyond 15s if multi-swing instability is of concern. Energy Function theory is a method
to describe the stability of power system and it eliminates the post-fault integration which
reduces the simulation time.
