Executive Summary

In this paper a new and efficient method for the reliable load flow solution of power network branches controlled by Flexible AC Transmission Systems (FACTS) is presented. In the various methods proposed in past, the formulations was derived in which the Jacobian matrix is in UDUT form, where U is a constant upper triangular matrix depending solely on system topology and D is a block diagonal matrix. Now this paper is presenting a new technique consisting of embedded series Flexible AC Transmission System (FACTS) devices, facilitated by a formulation of power flow equations with bus voltage magnitudes and line flows as independent variables. Using IEEE standard systems, the Line Flow-Based (LFB) formulation is shown to provide easy implementation with multiple series and shunt FACTS devices.
