Electric Grid Visualization: Hourly Generation, Load, Unserved Load, and Locational Marginal Prices during a 2018 Heatwave

Visualization of hourly generation, load, unserved load, and locational marginal energy prices in the western United States during a July 22-28 heatwave event in 2018. In addition to hourly time series data of each of the parameters, choropleth maps showing the hourly value for each balancing authority are provided as well as a county-level choropleth map of temperature.

Slow crack growth measurement using an electrical grid

Photolithography was used to produce a resistance grid on the surface of a DCB fracture specimen. The grid line spacings were 10 microns over a distance of 2 cm. Slow crack growth was measured on soda-lime-silica glass. At low values of K(I) (0.3 to 0.4 MPa.sq r + m, increased. Equations are given for the design of grids. The grid technique could be used to measure very slow crack growth at high temperature with appropriate compatible metal-ceramic materials.

Systems and methods for controlling electrical grid resources

The present invention relates to PMU-based control systems for dampening inter-area oscillations in large-scale interconnected power systems or grids to protect against a catastrophic blackout. The control systems receive phasor measurements from two or more locations on an AC transmission line and generates a power control command to a power resource on the grid.

Ransomware and Today's Electric Grid

Cyberattacks come in many forms, including one of the newest and most threatening of attacks: ransomware. The rise in ransomware impacts businesses small and large -- and have the potential to significantly disrupt the operations of critical infrastructure. This presentation will explain what utilities can expect from a ransomware attack, sharing examples from specific events, provide guidance on how to prepare for the unknown, and offer possible ways to respond when an attack occurs. The presentation will also discuss cybersecurity governance as an effective method in taking preventative action to ransomware by identifying and addressing vulnerabilities through monitoring and assessment.
