Senior Electrical Engineer, National Wind Technology Center
Ph.D., Physics, University of Colorado, Boulder
M.S., Physics, University of Colorado, Boulder
B.S., Electrical Engineering, University of Colorado, Boulder
Phone: 303-384-6945

Palmer joined NREL in 1986. In the fall of 1977, he took a year and half leave of absence from his professorship in the Electrical Engineering Department at the University of Colorado to assist in the creation of what has become the Wind Energy Test Site in the buffer zone adjacent to the Rocky Flats Atomic Energy Installation. During the next decade he kept in touch through occasional consulting at the Test Site. In 1986, he took early retirement from the University and was hired as a full-time employee at the Test Site. Early duties included engineering tests of local turbines at the wind site as well as membership of a traveling Design Review team that oversaw wind turbine subcontractors. Later responsibilities included about 5 years as Associate Technical Editor for Wind Energy Conversion in the Journal of Solar Energy Engineering. Another later duty was that of Operating Agent for Annex 13 of the International Energy Association Executive Committee for the Cooperation in the Development of Large-Scale Wind Systems. Following this, his work with the NREL low-speed, direct-coupled wind turbine resulted in several reports and papers, including Analytic Expressions for Maximum Wind Turbine Average Power in Rayleigh Wind Regime, (Carlin, 1997 AIAA Proceedings) and Some Analysis of Energy Production from the NWTC Variable Speed Test Bed, (Carlin and Fingersh, 1999 AIAA Proceedings). The former was awarded Best Conference Paper at the annual 1997 ASME Wind Energy Symposium. He has recently worked with the Wind Powering America project at state workshops and with Alan Laxson and Eduard Muljadi on a soon-to-be-published history of Variable-Speed Operation of Wind Turbines.

Matthew J. Churchfield

Postdoctoral Researcher
Phone: 303-384-7080

Matt began post-doctoral research work at NREL in August 2009. His work involves the use of computational fluid dynamics (CFD) to study the physical interactions of wind turbine wakes with other turbine wakes and with the surrounding atmospheric boundary layer. This is of interest in a wind farm setting where there are many turbines in relatively close proximity to one another. The wakes created by upstream turbines contain less momentum and more turbulence than the ambient wind; if these wakes impinge upon downstream turbines, those turbines may create less power and be subject to higher mechanical loading than in the non-wake situation. Ultimately, that can lead to less revenue generated and higher maintenance costs. A better understanding of these physical phenomena could lead to improved engineering tools that wind farm developers may use to design more efficient, less maintenance-intensive wind farms. Prior to NREL, Matt earned his master's and doctorate degrees in Aeronautical Engineering at Purdue University and his Bachelor of Science degree in Mechanical Engineering at the University of Nevada, Reno.

Since joining NREL in 1992, Karin has primarily focused on two research areas: 1) wildlife issues related to wind technology and 2) distributed wind turbine projects (both small and midsize).

Karin has worked on wind-wildlife issues since 1996. The overall objectives have been to understand the causes of wind turbine impacts to wildlife (including birds, bats, and habitat) and to develop strategies to reduce the potential for impacts. Karin represents NREL on the National Wind Coordinating Collaborative (NWCC), and the Wildlife Workgroup. She serves as the technical liaison for the Grassland Community Collaborative and the Sage Grouse Collaborative, and participates in the Bats and Wind Energy Cooperative. As NREL's point-of-contact, she is actively engaged in land-based wind-wildlife projects as well as marine wind activities.

Working on Distributed Wind (DW) projects since 2000, Karin has served as the Technical Monitor for a number of DW-related projects including Regional Field Verification (a field study of small wind turbines installed in the Pacific Northwest), Independent Testing (testing small wind turbines at the NWTC), and the North American Board of Certified Energy Practitioners (tasked with developing testing and certification for small wind turbine installers). Other DW projects Karin is involved with include Regional Test Centers and the Built Environment initiative. She also is the NREL lead for the Midsize Turbine Development initiative, which is focused on the development of turbines ranging in size between 100 kW and 1 MW. As an ASES member, Karin has served as the co-chair for the Small Wind Division and was recently elected as the chair.

Karin holds a B.S. in Economics and an M.A. in Environmental Administration, both from the University of California, Riverside.

Alan joined NREL (SERI) in 1984. He has led the Wind Turbine Code development and validation team at NREL since 1992. The team's major project has been the development of simulation codes for predicting the dynamic response and loads of wind turbine systems. These codes are extensively used by wind industry members in the design of wind turbines to decrease structural loads and increase fatigue lifetimes. More recently, Alan has been involved with incorporating control schemes for load alleviation and power enhancement into these analytical codes. He is currently writing his Ph.D. thesis on the control of large flexible wind turbines to enhance energy capture and reduce structural dynamic loads and response. These control schemes will be used in future large wind turbines to alleviate loads due to atmospheric turbulence.

Prior to joining NREL, Alan spent 5 years at the wind turbine research program at Rocky Flats, operated by Rockwell International. He performed analytical modeling and structural dynamic studies of wind turbine rotor systems. His graduate school research at CU is being funded through NREL and allows him to incorporate modern control schemes into wind turbine analytical codes. These control schemes will be tested on the Controlled Advanced Research Turbine at the NWTC in the near future.
