Cyber-Physical Anomaly Detection in Microgrids Using Time-Frequency Logic Formalism
No full textModern cyber-physical microgrids rely on the information exchanged among power electronics devices (i.e., converters or inverters with local embedded controllers) making them vulnerable to cyber manipulations. The physical devices themselves are susceptible to potential faults and failures. Effects of these cyber and physical anomalies can propagate throughout the entire microgrid due to information exchanged and the inherent low inertia of the distribution network. This work employs the parametric time-frequency logic (PTFL) framework to detect such cyber-physical anomalies. PTFL is a formalism to analyze the time-frequency content of the observable quantities of interest (such as current, voltage, or frequency) of power electronics devices in comparison with the predefined time-frequency properties. PTFL formalism is presented to detect the anomalies such as false data-injection attacks, denial-of-service attacks, and faults on a cluster of four DC microgrids and an inverter-populated IEEE 34-bus feeder system in a controller/hardware-in-the-loop environment

Flashpoint: How a Little-Known Sporting Event Fueled America\u27s Anti-Apartheid Movement
No full textForty years ago, a South African rugby tour in the United States became a crucial turning point for the nation’s burgeoning protests against apartheid and a test of American foreign policy.
In Flashpoint: How a Little-Known Sporting Event Fueled America\u27s Anti-Apartheid Movement, Derek Charles Catsam tells the fascinating story of the Springbok’s 1981 US tour and its impact on the country’s anti-apartheid struggle. The US lagged well behind the rest of the Western world when it came to addressing the vexing question of South Africa’s racial policies, but the rugby tour changed all that. Those who had been a part of the country’s tiny anti-apartheid struggle for decades used the visit from one of white South Africa’s most cherished institutions to mobilize against both apartheid sport and the South African regime more broadly. Protestors met the South African team at airports, chanted outside their hotels, and courted arrests at matches, which ranged from the bizarre to the laughable, with organizers going to incredible lengths to keep their locations secret.
In telling the story of how a sport little appreciated in the United States nonetheless became ground zero for the nation’s growing anti-apartheid movement, Flashpoint serves as a poignant reminder that sports and politics have always been closely intertwined.https://falconcommons.utpb.edu/utpb-facbooks/1025/thumbnail.jp

Intelligent anomaly identification in cyber-physical inverter-based systems
No full textModern cyber-physical systems have become more autonomous and distributed with the inclusion of advanced control architectures and communication networks. Power electronics-based inverters that employ extensive communication structures are integral part of such systems. The controllers for inverter-based systems rely on communication networks that make them vulnerable to cyber-physical anomalies. The cyber anomalies occur due to malicious attacks targeting the communication layer and physical anomalies are caused by power system faults in the physical layer of the microgrid. In this work, an intelligent anomaly identification (IAI) technique for such systems is presented utilizing data driven artificial intelligence tools that employ multi class support vector machines (MSVM) for anomaly classification and localization. The effects of cyber anomalies such as false data injection and denial of service attacks that target the communication network are considered in this work. In addition, the physical anomalies due to power system faults are also considered. The proposed technique utilizes statistical features extracted from measurements for optimal learning of a dual of MSVM classifiers. The mean absolute percentage error is used as a performance metric and the results are validated by comparing to artificial neural network, Naive Bayes classification and using real time simulations in OPAL-RT
