An Initial Exploration of Spatial Spreading of Cascading Failure in an Electric Power System
<p>Large blackouts typically involve the cascading outage of transmission lines. However, little is known about the overall patterns of cascading outages. This research processes and initially examines observed utility data to explore the spatial spreading of cascading failure. The utility data is …

Integrating demand into the U.S. electric power system : technical, economic, and regulatory frameworks for responsive load
The electric power system in the US developed with the assumption of exogenous, inelastic demand. The resulting evolution of the power system reinforced this assumption as nearly all controls, monitors, and feedbacks were implemented on the supply side. Time invariant, averaged retail pricing was a …
