Abstract

This paper describes a new hybrid approach, which combines the simulation of electromagnetic transient program (EMTP) for FACTS devices and the simulation of transient stability program (TSP) for the rest power system. In the interface between the two simulations, new techniques considering the effect of frequency deviation due to disturbances are proposed for improving simulation accuracy. Case studies on the IEEE 3-generator and the IEEE 10-generator New England systems demonstrate the improvement of the new method to the conventional EMTP/TSP one by comparing their simulation results during contingencies.
