Boundary Controlling UEP

The code runs Transient Stability Assessment based on the following methods

  1. Time domain simulation
  2. Potential Energy Boundary Surface (PEBS)
  3. Boundary Controlling u.e.p. Method (BCU)

The data is imported in PSAT format. The code closely follows the example in Sauer et.al. [1].
