Such systems were traditionally executed in the physical world and are now also cyber-enabled. This cyber-enabled energy system, called smart grid, can be envisioned as the marriage of information technology with the electricity network. While its increased dependence on cyber infrastructure aims to enable greater reliability, efficiency and capacity of power delivery, this reliance also creates a host of unfamiliar vulnerabilities. Due to the highly integrated and connected nature of smart grids, it is important to account for their salient cyber-physical coupling when making critical design decisions and identifying solutions to promote security.
In this dissertation, we present a flocking-theory inspired dynamical systems paradigm to model smart grid cyber-physical interactions related to smart grid stability. Such a biologically-inspired framework enables the convenient description of (discrete) cyber and (analog) physical couplings. Through this paradigm, we demonstrate real-time cyber-physical integrated control and communication strategies using “wisely”-placed phasor measurement units and energy storages to re-stabilize a smart grid system under various forms of cyber and physical attacks. Our research has evolved in three stages. We first propose a multi-agent dynamical systems paradigm to model the cyber-physical interactions related to smart grid stability. In our multi-agent framework each node, representing both electrical and information system components, is modeled as having dynamics that synergistically describe physical and information couplings with neighboring agents. Inspired by the analogy between the flocking behavior in the nature and the stability of the cyber-enabled synchronous generators, We develop a flocking-based scheme to formulate the cyber-physical integrated action for each agent. It is clear from our analysis framework that redundant cyber information acquisition and use increases risks of cyber-attack whereby indiscriminate cyber-dependence and -connectivity increases attack scope and impact. To address this problem, in the second stage, we extend the multi-agent paradigm to a two-tier hierarchical framework by effectively leveraging physical couplings between the agents and identifying the critical ones that increase vulnerability to cyber- or physical- attack. With the developed hierarchical framework, the cyber information redundancy is reduced by only leveraging cyber coupling at critical agents. In the context of the hierarchical framework, we analyze the physical impact of cyber attack. We focus on two major attacks widely effecting the smart grid, attacks on timely data delivery, such as Denial-of-Service (DoS) attacks, and attacks on information accuracy, such as false data injection attacks. The DoS attack can cause communication delay of critical cyber information and result in significant power delivery disruption. To defend against the DoS attacks, we propose an intelligent multicast routing strategy, called Goal-Seeking Obstacle and Collision Evasion (GOALiE), which is appropriate to smart grids and resilient to DoS attacks. We also develop a novel witness-based cyber-physical protocol whereby physical coherence is leveraged to probe and identify the false data injection on Phasor Measurement Unit (PMU) data and estimate the true information values for attack mitigation.},

Challenges stem from the need to develop intelligent models of cyber-physical attacks that produce salient disruptions and appropriately describe meaningful cyber-physical interdependencies such that they balance precision, scale and complexity. In our research, we present a foundation for the development of a class of intelligent cyber-physical attacks termed coordinated variable structure switching attacks whereby opponents aim to destabilize the power grid through controlled switching sequence. Such switching is facilitated by cyber attack and corruption of communication channels and control signals of the associated switch(es). We provide methods and theorems to construct such attack models and demonstrate their utility in the simulation of extensive system disturbances.
Our proposed class of cyber-physical switching attacks for smart grid systems has the potential to disrupt large-scale power system operation within a short interval of time. Through successful cyber intrusion, an opponent can remotely apply a state dependent coordinated switching sequence on one or more relays and circuit breakers of a power system to disrupt operation. Existence of this switching vulnerability is dependent on the local structure of the power grid. Variable structure systems theory is employed to e ectively model the cyber-physical aspects of a smart grid, determine the existence of the vulnerability and construct the destabilizing switching attack sequence. We illustrate the utility of the attack approach assess its impact on the di erent power system test cases including the single machine in nite bus power system model and theWestern Electricity Coordinating Council (WECC) 3-machine, 9-bus system through MATLAB/Simulink and PSCAD simulation environment. The results demonstrate the potential of our approach for practical attack.
Moreover, we build on our work in several ways. First, we extend the research to demonstrate an approach to mitigation within the variable structure system framework. We demonstrate via small signal analysis how through persistent switching a stable sliding mode can be used to disrupt a dynamical system that seems stable. We also design an approach to vulnerability analysis to assess the feasibility of coordinated variable structure switching attacks. Moreover, we study the performance of our attack construction approach when the opponent has imperfect knowledge of the local system dynamics and partial knowledge of the generator state. Based on the system with modeling errors, we study the performance of coordinated variable structure switching attacks in the presence of state estimation. Finally, we illustrate the concepts of attack model within the multiple switching framework, the cascading failure analysis is employed in the New-England 10-machine, 39-bus power system using MATLAB/Simulink and DSATools simulation environment.

The multi-agent robotics paradigm has attracted much attention due to the variety of pertinent applications that are well-served by the use of a multiplicity of agents (including space robotics, search and rescue, and mobile sensor networks). The use of this paradigm for most applications, however, demands economical, lightweight agent designs for reasons of longer operational life, lower economic cost, faster and easily-verified designs, etc.
An important contributing factor to an agent’s cost is its control architecture. Due to the emergence of novel implementation technologies carrying the promise of economical implementation, we consider the development of a technology-independent specification for computational machinery. To that end, the use of cybernetics toolsets (control and dynamical systems theory) is appropriate, enabling a principled specification of robotic control architectures in mathematical terms that could be mapped directly to diverse implementation substrates.
This dissertation, hence, addresses the problem of developing a technologyindependent specification for lightweight control architectures to enable robotic agents to serve in a multi-agent scheme. We present the principled design of static and dynamical regulators that elicit useful behaviors, and integrate these within an overall architecture for both single and multi-agent control. Since the use of control theory can be limited in unstructured environments, a major focus of the work is on the engineering of emergent behavior.
The proposed scheme is highly decentralized, requiring only local sensing and no inter-agent communication. Beyond several simulation-based studies, we provide experimental results for a two-agent system, based on a custom implementation employing field-programmable gate arrays.},
