Concerns regarding global warming, the finite nature of conventional energy reserves, energy security and rising costs are driving the need to find more efficient and renewable sources of energy. Unfortunately, renewable power sources, such as solar cells or wind farms, differ significantly from conventional power plants and integrating them into the power grid poses a number of challenges. This talk examines strategies for mitigating these challenges through case studies using wind power. The first presents a simple framework to study the use of storage combined with fast-ramping spinning reserves (back-up generation) to mitigate the inherent variability of renewable sources. This idea is then extended to address the question of how to place storage resources in order to simultaneously mitigate risks and minimize costs given different network topologies. Finally, an examination of the complementary problem of wind farm placement and its effect on system damping is carried out. Achieving the full potential of smart and clean power systems will require a combination of different generation schemes, storage, ancillary services and other energy assets as well as an understanding of how to best coordinate and distribute these resources.
Dennice Gayme is an Assistant Professor in the Department of Mechanical Engineering at Johns Hopkins University. She was previously a postdoctoral scholar in Computing & Mathematical Sciences at Caltech, where she received her doctorate in Control and Dynamical Systems in 2010 and was a recipient of the P.E.O. scholar award in 2007 and the James Irvine Foundation Graduate Fellowship in 2003. She received a Master of Science from the University of California at Berkeley in 1998 and a Bachelor of Engineering & Society from McMaster University in 1997 both in Mechanical Engineering. Prior to her doctoral work she was a Senior Research Scientist in the Systems and Control Technology and Vehicle Health Monitoring Groups at Honeywell Laboratories from 1999-2003. Dennices research interests are in the study of large-scale interconnected systems with an emphasis on renewable and efficient energy systems and wall turbulence.
