Control of Large Wind Turbines

Please attend the Lockheed-Martin sponsored ASSET seminar in Thornton Hall, Room E316, the University of Virginia, at 3:00 PM on Friday September 14, 2012.

Prof. Mark Balas, “Control of Large Wind Turbines: It Doesn’t Take a Weatherman to Know Which Way the Wind Blows”

Abstract: The next generation of utility-scale wind turbines will be larger and more flexible than earlier designs to promote greater energy capture and reduce the cost of energy.  It is here that the implementation of active feedback control is crucial to meet design objectives.  Not only must there be power regulation or optimization but also load mitigation to extend the life of the turbine.  Wind turbine dynamics modeling for active control is composed of four principal parts: (1) Aerodynamics and Inflow Behavior (2) Structural Dynamics (3) Feedback Control Algorithms and (4) Power Electronics.  Active control is a relatively new technology for wind turbines.  Basic control theory used in this talk is linear time-invariant and periodic control using disturbance accommodation, but with a strong connection to the aerodynamics and structural dynamics of wind turbines.  This talk will be a non-specialist’s tutorial on control of large wind turbines but will also introduce our adaptive control work in this research area.  I hope, when we are done, no one will ever be able to “kick sand in your face” about utility-sized wind turbine control.

This seminar is a great opportunity to broaden your base of knowledge, which can help spark new ideas in your own research, and could be invaluable in job interviews.  The Q&A based Fireside Chat session will be useful to learn best-current practices. Plan some questions for this distinguished faculty member.

Clean Energy Competition

Have an idea for developing new energy technologies?

Want to show off UVa’s entrepreneurial talent?

As part of the Obama Administration’s effort to support the next generation of American clean energy entrepreneurs, the Department of Energy is offering $2 million to student-entrepreneurs for new clean energy solutions.  These funds will be awarded through a series of five regional competitions around the country.
Students at UVa and other universities in the Southeast are invited to compete in the ACC Clean Energy Challenge.  The winner of this challenge will receive a $100,000 prize and compete in the DOE National Clean Energy Business Plan Finals in Washington, D.C., in summer 2012.

To enter, you or your team should register at

Key Dates and Steps:

23 March 2012      Executive Summary (3 pages) and an Investor Video Pitch (3-5 minutes) due.  (During this preliminary round, students compete with other teams from their university.)

10 April   Teams notified of advancement to Southeast Regional Competition.

20 April        Full Commercialization Plans due.

24-25 April    Fifteen teams gather at the University of Maryland to make 20-minute presentations and compete for top prizes.

If you are a UVa student and planning to submit an entry, please contact Prof. Bernie Carlson,, so that he can keep track of UVa’s participation.

APPA Student Research Grants/Internships

FROM:             Michele Suddleson, DEED Program Manager, American Public Power Association

It is my pleasure to inform you that the American Public Power Association (APPA) awards student research grants/internships each year to university students as part of its Demonstration of Energy-Efficient Developments (DEED) Program.  APPA is the service organization for the nation’s community-owned electric utilities.  DEED is APPA’s research program that funds innovative, energy related research.

Please assist us in notifying your students about our opportunities by posting copies of our student flyer in prominent locations at your university, sending out on appropriate university list servers, and providing copies of the notice to your university’s student financial aid office.  Below is a brief synopsis of the scholarships we offer.

Ten  $4,000 Student Research Grants/Internships

Ten $4,000 student research grants/internships are awarded each year to undergraduate/graduate university students to conduct research on a project/internship in conjunction with a DEED member utility or as part of the students’ curriculum requirements if approved by a DEED member.  A mid-project report, final report, and abstract are required.  A sample Grant/Internship application can be found here.

Annual Application Deadlines: February 15 and October 15

One $5,000 Technical Design Project (Research Grant)

DEED awards one Technical Design Project each year to a student or group of students studying in an energy related discipline.  This grant is geared towards engineering students working on their senior project.  The student(s) academic advisor must approve the project and a mid-project report, final report, and abstract are required.  Travel expenses (up to $3,000) are also included in this grant for the student(s) to present their work at APPA’s Engineering and Operations Technical Conference held each spring.  A sample Technical Design Project application can be found here.

Annual Application Deadline:  October 15

Applications offered here are only to be used as a sample of the questions and information that will be required as we are launching a on-line application process January 3, 2012.

Accelerator Driven System (ADS) in Support of Sustainable Nuclear Power Program in India

Srikumar Banerjee

Chairman, Atomic Energy Commission & Secretary, Department of Atomic Energy, India


Energy policy of populous country like India caters to sustain fast economic growth without burdening environment with deleterious effects and yet conserve resources for future generations. Nuclear energy would be essential for such goals even though other renewable energy sources could provide incremental supplements.

India is not endowed with large deposits of basic nuclear fuel uranium, but thorium as fertile fuel is abundantly available. Long-term goal of our nuclear energy policy is to harness thorium reserves which will last for a couple of centuries. This policy is manifested in the 3-stages of fuel cycle and reactor technology development program. A closed uranium fuel cycle is planned alongside heavy water reactors of first stage. The second stage would enhance fuel stockpiles with fast breeder reactors and provide seed fuel for thorium utilization in eventual third stage.

However, sustainable thorium fuel utilization with capacity growth requires use of sub-critical reactor system with external supply of non-fission neutrons to achieve high & economic fuel burn up (of thorium). Reprocessing of fuel and its recycling would be essential part of such a scheme. Recycling of uranium spent fuel would also reduce the radiotoxicity, whereas thorium utilization would not create large quantities of actinides waste. Final “ashes” of uranium fuel would be minor actinides which are transmuted safely by fission in dedicated sub-critical reactor.

An energy efficient way to supplement reactor with external non-fission neutrons is by nuclear reaction of spallation using high energy proton accelerator and its beam power intensity of several megawatts. This forms basic configuration of Accelerator Driven System (ADS). We have an integrated R&D program for ADS that is implemented with analytical and technology studies and experimental facilities in BARC and other institutes of Indian Department of Atomic Energy. Development of linear proton accelerator (linac) having low beam loss, high reliability and energy efficiency would require application of RF superconductivity and associated cryogenics. Termination scheme of intense proton beam at spallation target needs development of liquid lead and lead-bismuth technology and high temperature structural materials.

The above aspects of ADS in support of sustainable nuclear power in India are covered in the talk and status of activities initiated under R&D program on ADS is elaborated.
