Wide-Area Measurement And Applications In Power System Dynamic Modeling And Control, Yong Liu

Doctoral Dissertations

Synchrophasor has been becoming the foundational element of power grid wide-area measurement system (WAMS) since first developed in 1980s. By utilizing global positioning system (GPS) time synchronization technique, synchrophasors offer highly accurate time-synchronized phasor measurements that can provide system operators with real-time information of operation status.

Frequency disturbance recorders (FDRs) are installed on the distribution level to measure power system dynamics and considered as a type of single-phase synchrophasors. In this dissertation, a detailed procedure for the FDRs’ calibration is summarized and a preliminary test of their dynamic performance is carried out. Moreover, this dissertation investigates the impact of GPS …

Understanding The Attitude-Behavior Gap For Renewable Energy Systems Using Behavioral Reasoning Theory, Aidan O'Driscoll, Marius Claudy, Mark Peterson

Articles

Consumer adoption of renewable energies is an important step towards less carbon-intensive and more sustainable energy systems. But despite growing ecological awareness and articulated preferences for green products, renewable energies face slow rates of diffusion in consumer markets. This has been hard to explain given consumers’ favorability to the concept of products that lower one’s impact on the natural environment. This study uses data from 254 homeowners in Ireland to investigate the psychological process of adopting a renewable energy system – solar energy panels. Applying Behavioral Reasoning Theory (BRT), this research examines a proposed model in which reasons both for …

Ferritin-Based Photo-Oxidation Of Biomass For Nanoparticle Synthesis, Bioremediation, And Hydrogen Evolution, Oscar Petrucci

Theses and Dissertations

The cell is the basic unit of all living organisms. It is an amazing machine capable of self-replicating, growing, and synthesizing and shuttling thousands of compounds. To perform all of these activities the cell needs energy. The original source of energy for all living beings is the Sun. The energy of the sun is collected by the autotrophs (mostly plants) through photosynthesis and stored in the chemical bonds of carbohydrates and lipids through carboxylic acid intermediates; animals use these compounds to obtain the energy for their cells. Most of the energy extracted by the cell comes from the citric acid …

See The Mojave!, John C. Nagle

John Copeland Nagle

This article examines how the law is being asked to adjudicate disputed sights in the context of the Mojave Desert. The Mojave is the best known and most explored desert in the United States. For many people, though, the Mojave is missing from any list of America’s scenic wonders. The evolution in thinking about the Mojave’s aesthetics takes places in two acts. In the first act, covering the period from the nineteenth century to 1994, what began as a curious voice praising the desert’s scenery developed into a powerful movement that prompted Congress to enact the CDPA. The second act …

Green Harms Of Green Projects, John C. Nagle

John Copeland Nagle

This article describes the recent development of renewable energy to examine environmental law’s three contrasting approaches to the green harms of green projects. Sometimes the law allows the green benefit regardless of the green harm. Sometimes the law prohibits the green harm regardless of the green benefit. And sometimes the law allows a balancing of all of the harms and benefits, green or not. Given these options, I argue that the law should not ignore or understate green harms even if they are caused by green projects. There are some types of green harms that no benefit can justify. But …

The Carbon Rent Economics Of Climate Policy, Matthias Kalkuhl, Robert J. Brecha

Physics Faculty Publications

By reducing the demand for fossil fuels, climate policy can reduce scarcity rents for fossil resource owners. As mitigation policies ultimately aim to limit emissions, a new scarcity for “space” in the atmosphere to deposit emissions is created. The associated scarcity rent, or climate rent (that is, for example, directly visible in permit prices under an emission trading scheme) can be higher or lower than the original fossil resource rent. In this paper, we analyze analytically and numerically the impact of mitigation targets, resource availability, backstop costs, discount rates and demand parameters on fossil resource rents and the climate rent. …

Biofuel From Microalgae – A Review On The Current Status And Future Trends, Rajee Olaganathan, May Zaw Htet, Lim Yan Ling, Sek Hui Yun

Publications

The constant reliance on fossil fuel energy resources is unsustainable, due to both depleting world reserves and increasing green house gas emissions associated with their use and thus there are dynamic research at the global level envisioned at developing alternative renewable and potentially carbon neutral solid, liquid and gaseous biofuels as alternative energy resources. The contemporary knowledge and technology predictions have proved that among the third generation biofuels especially those derived from microalgae are considered the best reasonable alternative energy resource compared to undeniable drawbacks of first and second generation biofuels. Moreover, its efficiency to sequester carbon from the atmosphere …

Renewable Energy Through Agency Action, Amy L. Stein

UF Law Faculty Publications

Despite the many societal benefits associated with renewable energy, it is used to generate only about 5 percent of our nation's electricity needs. The bulk of governmental efforts to rectify this situation have disproportionately impacted private actors. This Article argues that the federal government should expand its efforts to more fully capture the gains that can be achieved by targeting both private and public actors, particularly federal agencies. Federal agencies have enormous purchasing power that can be channeled toward using electricity and fuels derived from renewable energy. Federal agencies are some of the largest consumers of electricity. Federal agencies manage …

Power To The People: Why We Need Full Federal Preemption Of Electrical Transmission Regulation, Max Hensley

University of Michigan Journal of Law Reform

State and federal governments have made significant investments in the development and installation of renewable energy technology. However, further increases in renewable power use have been stymied by the continued mismatch between the national interest in connecting consumers with utility-scale wind and solar installations and state and local control over the siting of electrical transmission lines. Because renewable power potential is often located far from consumers, transmission lines must cross multiple jurisdictions whose local interests have tended to prevent or significantly delay development. This Note analyzes that disconnect, reviews academic and legislative proposals to overcome it, and proposes a way …

A Wind Resource Assessment Of The Mississippi Delta, Jessica Dealy

Theses and Dissertations

The hypothesis tested was that a site in Leflore County, Mississippi, located on the bluff above the Mississippi River flood plain (the Delta) would experience wind speeds adequate for power generation. Wind measurements were collected at a height of 55 m (above ground level) between October 2011 and October 2012. Winds at this height were predominately southeasterly with a mean wind speed less than 4 m/s. Winds did not accelerate above this bluff. Low surface friction of the Delta was not beneficial due to the predominant wind direction. To better understand Delta wind patterns, an S-mode varimax-rotated principal component analysis …

Linking Land Use With Climate Change And Sustainability Topped State Legislative Land Use Reform Agenda In 2008, Patricia E. Salkin

Patricia E. Salkin

Linking land use with climate change and sustainability topped state legislative land use reform agenda in 2008. The only discernible state land use reform trends in 2008 have focused primarily on themes surrounding sustainability. Many states pursued statutory reforms to address the strong linkages between land use and climate change, green development and affordable housing. Only one state, Michigan, focused on recodification of its planning and zoning enabling acts.

A Path To A Renewable Energy System: A Financing And Regulatory Model, Edward Patrick Kelly

Masters Theses, 2010-2019

As the effects of climate change become more and more evident, the necessity of transitioning to a carbon-free economy and powering our energy and transportation systems from renewables energy sources is quite evident. This transition to a renewable- based energy system will be a massive undertaking, similar to the efforts put into WWII, where the country was united with unity of purpose. Taking on the vested interests of the fossil fuel industry and all their subsidiaries will take a political will that does not exist in this country at this time. Hermann Scheer describes what he calls a social movement; …

An Efficient Contracting Approach To Rural Electric Cooperatives And The Development Of Upper Midwest (U.S.) Wind Resources, Bart D. Finzel, Arne Kildegaard

Economics & Management Publications

Many factors support the likelihood of major wind power deployment in the Upper Midwest of the U.S. over the next two decades. This paper specifically considers the dilemma faced by the existing rural electric co-ops (RECs), to whom wind development poses simultaneously a threat and an opportunity. We argue that the threat can be ameliorated through more appropriate tariff strategies, and that there is an efficient-contracting rationale for RECs to take the lead in future development of the wind resource.

Peaceful Coexistence: Independent Microgrids Are Coming, Sara C. Bronin, Paul Mccary

Sara C. Bronin

The growing push for microgrids in the United States over the last five years has generated a lot of excitement. Those worried about our aging transmission and distribution infrastructure hope microgrids can reduce demands on that grid, while increasing reliability. Environmentalists and energy efficiency advocates think microgrids can help us both decrease reliance on fossil fuels and improve the way we utilize waste heat. Academics love the concept, because microgrids—an out-of-the-box approach with far-reaching implications on user-utility relationships—provide great fodder for research and commentary. Perhaps most significantly in this struggling economy, a growing number of companies have invested millions in …

Attracting Fdi: The Chilean Government's Role Promoting Renewable Energy, Kyle Herman

Dr. Kyle S. Herman

The development and implementation of renewable energy power plants is important for Chile in order to increase energy security, supply remote mines with electricity, and eventually decrease energy costs. The Chilean government has promoted renewable energy and attracted Foreign Direct Investment (FDI) to develop large-scale renewable energy projects. However, the policies cannot sufficiently attract FDI in unproven renewable energies such as Concentrated Solar Power, though it is proven elsewhere. This paper examines the Chilean government’s renewable energy policies, related government agencies, and the extent that these provide a stable backdrop for FDI in large-scale renewable energy projects. Following that summary, …

Indigenous Communities In Panama Commemorate March Against Open-Pit Mining In Which Two Protestors Were Killed, Louisa Reynolds

NotiEn: An Analytical Digest About Energy Issues in Latin America

This article outlines a commemorative anti-mining march in Panama that took place early February 2013. The march marked the one year anniversary of Ngãbe Buglé indigenous community protests against the elimination of an article in a mining bill that outlawed mineral extraction on the Ngãbe Buglé reservation. They were also protesting the construction of the Barro Blanco hydroelectric project without an environmental impact assessment and prior consultation (as stipulated in ILO Convention 169). The article examines the Martinelli government's response to the protests, in addition to their failure to consult with the indigenous community on either of the projects.

Wind Power, Public Power: Evaluating Public Participation In New England Land-Based Wind Development, Gwen M. Miller

Masters Theses 1911 - February 2014

Wind energy is a means of energy production without carbon emissions, facilitating regional and national energy security. While there are currently no offshore wind farms in the United States, there has been growing success in building land-based wind capacity. Within the wind industry, there is a call for a streamlined permitting process, as well as an objective evaluation of current stakeholder processes. Within city and regional planning, the stakeholder process and public participation in general have long been subject to research and discourse, as scholars and practitioners alike seek to identify and typify what exactly makes public participation robust or …

Planar Organic Photovoltaic Devices, Feras Alzubi

Electronic Theses and Dissertations

Organic Photovoltaic devices (OPV) are considered to be attractive candidates for clean and renewable energy source because of their potential for low cost of fabrication, easy processing, and their mechanical flexibility. The device efficiency of OPV cells are limited by several factors. Among them are: (i) donor-acceptor interface, (ii) morphology of the materials, (iii) electrode-organic semiconductor (OSC) interface and (iv) device architecture such as active material thickness and electrode separation. Although, the donor-acceptor interface has been studied in detail, the commonly prevalent vertical OPV device structure does not allow a good understanding of the other key issues as the vertical …

Harmonizing Distributed Energy And The Endangered Species Act, J. B. Ruhl

San Diego Journal of Climate & Energy Law

This Article explores ways of harmonizing distributed energy and the ESA, a goal consistent with the national policy for renewable energy conservation. Several legal practitioners and scholars have identified the ESA as a potentially significant constraint on the siting and operation of wind power facilities. The ESA has also been identified as a potential barrier to renewable energy in general, as solar power, biomass, and ocean tide and wave facilities could have their own sets of impacts triggering ESA regulation. But most of this attention has been devoted to utility-scale renewable energy, with distributed energy largely ignored or perhaps assumed …

Smart Incentives For The Smart Grid, Roberta F. Mann

Roberta F Mann

Clean, renewable energy from the sun and wind—the green revolution is supposed to change the world. Since 2005, the United States has increased government investment in renewable energy generation, both from direct subsidies and indirectly through tax subsidies. Many other countries also provide incentives for producing electricity from renewable sources. But before renewable energy can change the world, it has to get to the customers who use it. Thomas Edison did change the world when he developed the first working electric power system. Unfortunately, the system for transmitting electrical power throughout the United States (the “grid”) has not changed much …
