SVC and TCSC Implemented into a Newton-Type Harmonic Power Flow Algorithm

The methodology for including generators as PV buses in a Newton-type harmonic power flow (HPF) program presented in a previous paper is extended here to include electronic devices. Application examples including a static VAr compensator (SVC) and a thyristor controlled series compensator (TCSC) are presented. Although the calculation of the firing angles for such devices needs an internal iterative procedure, in the overall the HPF methodology does not require an iterative procedure for satisfying the generator constraints and, as a consequence, it nearly preserves the quadratic convergence characteristics of the Newton approach.
