Abstract :
This paper details a technique in the time domain for the fast periodic steady state solution of systems with unified power flow controllers (UPFCs) incorporating three strategies for the practical representation of the UPFC commutation process. The computation of the periodic steady state solution of power systems with UPFCs including the proposed UPFC control strategies is efficiently obtained by extrapolation to the limit cycle using a Newton method based on a numerical differentiation (ND) procedure. The periodic steady state solution is validated against the solution obtained with the electromagnetic transient program PSCAD/EMTDC and against an implementation with the Power System Blockset (PSB) of SIMULINK.
