Power Systems Engineering Center

The NREL Power Systems Engineering Research Center is addressing the challenges of modernizing the electric grid at all scales through high-impact research and development. As part of NREL's energy systems integration program, NREL's power systems engineering researchers work with the electricity industry on strategies for effectively interconnecting renewable resources and emerging energy efficiency technologies with the existing electric power system.

Dr. Ben Kroposki is the Director of the Power Systems Engineering Center, where he leads NREL's strategic research in the planning and operations of electrical power systems. His expertise is in the design testing and integration of renewable and distributed power systems, and he has more than 100 publications in these areas. As an IEEE Fellow, Dr. Kroposki was recognized for his leadership in renewable and distributed energy systems integration. He has served on a number of IEEE technical standards working groups and chaired IEEE 1547.4, the first international standard on microgrid design and operation. He has also served as an editor for IEEE Journal of Photovoltaics, IEEE Transactions on Sustainable Energy, and IEEE Power & Energy Magazine. He received his bachelor's and master's degrees in electrical engineering from Virginia Tech and his Ph.D. from the Colorado School of Mines.

The Power Systems Engineering Center is made up of four groups aligned with key technology focus areas of the U.S. Department of Energy's Grid Modernization Initiative:

  • Integrated Devices and Systems: Developing and evaluating grid technologies and integrated systems and demonstrations
  • Sensing, Measurement, and Forecasting: Measuring weather resources and power systems, forecasting resources and grid conditions, and converting measurements into operational intelligence
  • Power Systems Operations and Controls: Developing methods for real-time operations and controls of power systems at any scale
  • Power Systems Design and Studies: Developing new power system analysis tools and algorithms, evaluating power system and market design and performance, and conducting power system planning, operations, and protection studies.

Supporting Facilities

The Energy Systems Integration Facility supports most of the R&D at the Power Systems Engineering Center. It can be used to design, test, and analyze components and systems to enable economic, reliable integration of renewable electricity, fuel production, storage, and building efficiency technologies with the U.S. electricity delivery infrastructure.

New grid integration capabilities at the National Wind Technology Center will allow testing of many grid integration aspects of multi-megawatt, utility-scale variable renewable generation and storage technologies.

The Distributed Energy Resources Test Facility can be used to characterize, test, and evaluate distributed generators, interconnection systems, controls, and procedures. Standards associations and industry have taken advantage of NREL's distributed energy capabilities to evaluate and validate their products and processes.
