The vulnerability of false data injection attacks on real-time electricity pricing for the power grid market has been recently explored. Previous work has focused on the impact caused by attackers that compromise pricing signals and send false prices to a subset of consumers. In this paper we extend previous work by considering a more powerful and general(More)
— The Kuramoto oscillator has been widely studied because it can model biological, social, chemical, and engineering problems. Conditions for frequency synchronization of a network of Kuramoto oscillators have been well established, but it depends on the connectivity of the network and on the natural frequencies. In this work we propose a consensus-based(More)
— Motivated by the increasing interest in networked multi-agent systems and the wide number of applications in decentralized distributed control of smart grids, we address the problem of synchronization when each node (e.g., a microgrid, a distributed generator) is modeled as a linear-time continuous system whose output measurements are sent through(More)
While attacks on information systems have for most practical purposes binary outcomes (information was manipulated/eavesdropped, or not), attacks manipulating the sensor or control signals of Industrial Control Systems (ICS) can be tuned by the attacker to cause a continuous spectrum in damages. Attackers that want to remain undetected can attempt to hide(More)
Most government, industry, and academic e orts to protect the power grid have focused on information security mechanisms for preventing and detecting attacks. In addition to these mechanisms, control engineering can help improve power grid security. A large body of work focuses on power grid system device vulnerability assessment 1 ; however, successfully(More)
—Networked Control Systems (NCS) has been one of the main research areas in the last few years, due to the benefits of the insertion of a communication network in distributed systems, and the widely area of applications such as tele-operations, robotics, UAVs, power systems, among others, and new growing areas like smart grids and Cyber-Physiscal Systems.(More)
