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

Modular Transformer Converter-Based Convertible Static Transmission Controller for Transmission Grid Management
TL;DR: In this paper, the concept of convertible static transmission controller (CSTC) using modular transformer converter (MTC) as the building block is investigated, and the algebraic models of the CSTC are derived in two different operation modes (series-shunt and shuntshunt connecting configurations).

Cost-Benefit Analysis of Moving-Target Defense in Power Grids
TL;DR: This analysis is primarily based on a direct current (dc) power flow model, and it is shown that the perturbations designed using this model are also effective in detecting FDI attacks against ac power flows and the cost-benefit tradeoff still holds under the ac power model.

Moving-Target Defense for Detecting Coordinated Cyber-Physical Attacks in Power Grids
TL;DR: The main idea of the proposed approach is to invalidate the knowledge that the attackers use to mask the effects of the physical attack by actively perturbing the grid’s transmission line reactances using distributed flexible AC transmission system (D-FACTS) devices.

Data-Driven False Data Injection Attacks Against Power Grids: A Random Matrix Approach
TL;DR: In this article, the problem of constructing false data injection (FDI) attacks that can bypass the bad data detector (BDD) of a power grid is addressed, where the attacker is assumed to have access to only power flow measurement data traces and no other prior knowledge about the grid.
