Risk-Based Machine Learning Approaches For Probabilistic Transient Stability, Umair Shahzad
Risk-Based Machine Learning Approaches For Probabilistic Transient Stability, Umair Shahzad
Department of Electrical and Computer Engineering: Dissertations, Theses, and Student Research
Power systems are getting more complex than ever and are consequently operating close to their limit of stability. Moreover, with the increasing demand of renewable wind generation, and the requirement to maintain a secure power system, the importance of transient stability cannot be overestimated. Considering its significance in power system security, it is important to propose a different approach for enhancing the transient stability, considering uncertainties. Current deterministic industry practices of transient stability assessment ignore the probabilistic nature of variables (fault type, fault location, fault clearing time, etc.). These approaches typically provide a conservative criterion and can result in expensive …

Executive Summary
Changes in climate create diverse challenges across the U.S. energy system. Some energy infrastructure assets have already suffered damage or disruption in services from a variety of climate-related impacts, such as higher temperatures, rising sea levels, and more severe weather events. In the absence of concerted action to improve resilience, energy system vulnerabilities pose a threat to America’s national security, energy security, economic wellbeing, and quality of life.
Building climate change resilience into our energy infrastructure planning is a challenging and complex undertaking. Planning horizons can span several decades (the typical service life of most energy assets), associated …
Recent Legislation To Promote Wind Energy In Nebraska, Ryan Lemke
Recent Legislation To Promote Wind Energy In Nebraska, Ryan Lemke
Department of Environmental Studies: Undergraduate Student Theses
Nebraska is currently ranked 4th in the nation for wind energy potential, but ranks low in actual wind power production. The lack of wind energy production could be the result of Nebraska’s unique public power districts that have eminent domain of distribution and retail sales of electricity in the State. Public Power districts are prohibited from receiving benefits of state and federal tax incentives for the development of wind farms, however some Nebraska power districts still pursue wind energy as a renewable source of energy.
Recent legislation changes, including the passing of laws LB629 and LB1048, have provided the State …
Gasoline: The Achilles' Heel Of U. S. Energy Security, Robert W. Weaver
Gasoline: The Achilles' Heel Of U. S. Energy Security, Robert W. Weaver
US Department of Energy Publications
The United States must balance securing our energy future with protecting our environment from climate change. A holistic approach is required to solve this complex problem. We must reduce demand for petroleum, improve energy efficiency, and develop feasible alternative energy solutions to include emission capture technologies.
The United States remains the largest consumer of energy products in the world and is the second leading producer of green house gas (GHG) emissions. Our dependence on imported petroleum is undermining our control of our national security interests. Petroleum comprises 63% of the United States’ energy consumption, with the transportation sector accounting for …
