Over the years, the Smart Grid has come to mean several things, from the inclusion of smart meters and smart energy management resources to the use of distributed sensing and digital communication to improve situational awareness, energy management, and control at grid scale. The objectives of the Smart Grid are multi-faceted and are intended to realize improvements to efficiency, flexibility, resiliency, and reliability of the grid while enabling greater renewable energy penetration. Increasing the penetration of distributed renewable sources, however, poses technical challenges for grid management. The grid has been optimized over decades to rely upon large centralized power plants with well-established feedback controls, but now non-dispatchable, renewable sources are displacing these controllable generators. Power electronic coupled energy systems are not, in general, required to provide frequency and voltage support through feedback compensation. This may lead to both straightforward and rather nuanced problems, both of which we intend to mitigate through new controls. In this talk, the motivations for Smart Grid technology development and for increased renewable energy penetration will be discussed, new requirements for grid-connected distributed systems will be reviewed, and specific examples of work being done at Sandia National Laboratories to develop new advanced controls for grid and energy resource management will be presented.
Jason Neely received B.S. & M.S. degrees in Electrical Engineering from the University of Missouri-Rolla in 1999 and 2001 respectively. From 2001-2007, he worked at Sandia National Labs in the Intelligent Systems & Robotics Center. In 2007, he returned to school and received his PhD in Electrical and Computer Engineering at Purdue in 2010 for development of new control techniques for power electronics. Since 2010, Jason has been a researcher at Sandia National Labs focusing on grid integration of power electronic based renewable energy sources and energy storage systems. He has authored or co-authored over 60 technical publications, focusing on power electronics and power electronics applications.
