TLDR
In this article, a distributed series impedance (DSI) and a distributed static series compensator (DSSC) are shown that can be clipped on to an existing power line and can, dynamically and statically, change the impedance of the line so as to control power flow.Abstract:
Flexible AC transmission systems (FACTS) devices are used to control power flow in the transmission grid to relieve congestion and limit loop flows. High cost and reliability concerns have limited the widespread deployment of FACTS solutions. This paper introduces the concept of distributed FACTS (D-FACTS) as an alternative approach to realizing cost-effective power flow control. By way of example, a distributed series impedance (DSI) and a distributed static series compensator (DSSC) are shown that can be clipped on to an existing power line and can, dynamically and statically, change the impedance of the line so as to control power flow. Details of implementation and system impact are presented in the paper, along with experimental results.read more

Power flow control and N-1 contingency analysis with DSRs in unbalanced transmission networks
TL;DR: In this article, the authors investigated the design of DSRs to control power flow over transmission lines to alleviate overloads due to load growth under single line contingencies, where the IEEE 39 bus standard model is modified to a 3-phase, unbalanced transmission model with 345kV lines that accounts for tower geometry.
