Abstract

This paper presents the load-flow modeling and steady-state capabilities of the bundle-controlled line impedance modulator (LIM). This distributed flexible ac transmission system device is under development for the management of power flows. In particular, this paper presents the back-to-back interconnection of two bundle-controlled line segments. The LIM configuration is very interesting from an economic and operational point of view: it enables continuous control of the transmission-line impedance from its standard value up to 1.64 p.u. and, as a result, the power flow can be reduced smoothly.
