In order to assess the resilience of a system, a set of measures must be defined. Varying control architecture while considering such a system of metrics targeted at resilience can determine the relative merit of the architectures with respect to the resilience of the system. Traditionally, electricity distribution is concerned with delivery of power from transmission or sub transmission to consumer...
The transition from the traditional power grid to the smart grid improves reliability, performance, and management, while simultaneously increasing its susceptibility to cyberattacks. One of the biggest weaknesses in grid security is the human agent responsible for its maintenance and operations. As such, it is crucial to embed hands-on understanding of grid operations and security, especially for...
As the transmission network has evolved over time, it has been operated closer to its limits and as a result lacks the ability to handle severe contingencies such as extreme weather, natural disasters, major generation failure, loss of transmission lines, or cyber-attacks. Depending on the timing of the event, these conditions could lead to cascading problems which can bring down an area larger than...
Over the years, many research projects have been performed and focused on finding out the effective ways to balance the power demands and supply on the utility grid. The causes of the imbalance could be the increasing demands from the end users, the loss of power generation (generators down), faults on the transmission lines, power tripped due to overload, and weather conditions, etc. An efficient...
Resilient control systems in critical infrastructures require increased cyber-security and state-awareness. One of the necessary conditions for achieving the desired high level of resiliency is timely reporting and understanding of the status and behavioral trends of the control system. This paper describes the design and development of a fuzzy-neural data fusion system for increased state-awareness...
Tomography, used to create images of the internal properties and features of an object, from phased array ultasonics is improved through many sophisiticated methonds of post processing of data. One approach used to improve tomographic results is to prescribe the collection of more data, from different points of few so that data fusion might have a richer data set to work from. This approach can lead...
