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

An H-Bridge-Based Single-Phase VAr Generator With Minimum DC Capacitance
TL;DR: In this paper, an H-bridge-based single-phase VAr generator with minimum dc capacitance is proposed, which reduces the dc-bus capacitor to 1/10th of the size compared to that of the sinusoidal pulse width modulation (SPWM)-modulated H-BR inverter, without increasing components' count.

Moving-Target Defense Against Cyber-Physical Attacks in Power Grids via Game Theory
TL;DR: This work proposes a moving target defense strategy to detect coordinated cyber-physical attacks against power grids by invalidating the knowledge that the attackers use to mask the effects of their physical attack by actively perturbing the grid’s transmission line reactances via distributed flexible AC transmission system (D-FACTS) devices.
