2017 R&D 100 Award: Control System for Active Damping of Inter-Area Oscillations
Today, electric power grids operate well below transmission capacity to avoid widespread outages due to inter-area oscillations. This new control system improves electric power grid reliability by continuously damping inter-area oscillations, allowing greater power transfer. This control system is the first successful grid demonstration of feedback control, making it a game changer in efforts to transform the existing grid into the future smart grid. Watch the video.

Jean-Paul Watson, Ph.D.
Jean-Paul Watson is a distinguished member of technical staff in the Discrete Math and Optimization Department at Sandia National Laboratories. He has over 13 years of experience applying and analyzing algorithms for solving difficult combinatorial optimization and informatics problems in fields ranging from logistics and infrastructure security to power systems and computational chemistry. His research currently focuses on developing methods for approximating the solution of large-scale deterministic and stochastic mixed-integer programs with application to electricity grid operations and planning. He presently leads projects at Sandia for stochastic economic dispatch, stochastic optimization for the power grid, and stochastic MINLP. Previously, he developed solutions for real-world stochastic optimization problems in logistics (Lockheed Martin and the US Army) and sensor placement (US Environmental Protection Agency). Additionally, he led the development of programs involving the use of semantic graph technologies for performing geospatial imagery analysis. He is a co-developer of Sandia’s Pyomo open-source software package for modeling and solving optimization problems, and he has published over 45 journal articles in the areas of optimization algorithms and their application.
