Abstract

The paper describes an analytical model for unbalanced operation of the unified power flow controller (UPFC). This nonlinear, time-invariant model is expressed in terms of dynamic symmetric components, and it is validated on a benchmark power system example taken from the literature. The model is evaluated via simulations in unbalanced operation and during unbalanced (one phase to ground) faults. The model achieves an accuracy comparable to detailed time-domain models, in addition to a reduction in simulation time
