Versatile model for power flow control using FACTS devices

Increased loading of power systems, and environmental restrictions, combined with a world wide deregulation of the power industry, require more effective control means for power flow control and voltage support. From the point view of steady-state analysis, this paper concentrates on building up a versatile model for all types of FACTS devices. In this respect, the decomposed power injection model (PIM) is proposed. Based on the model, a novel framework for power flow control, using FACTS devices, is adopted to derive FACTS control parameters. In order to take full advantage of the optimal multiplier Newton-Raphson power flow method (OMNR) for power flow with embedded FACTS devices and interior point linear programming (IPLP) for power flow control, a rectangular-polar hybrid formulation is adopted. Numerical results on a modified IEEE 5-node network are presented to illustrate the proposed approach.
