Title: Control and Integration of Fossil, Renewables, and Nuclear Power Generation Systems – Recent Advances and Current Challenges.

Joseph Bentsman, John Sorge, Yury Orlov, Luis T. Aguilar, Kwang Y. Lee, Eugenio Schuster

Some key breakthroughs attained under recent/current industry/federal support in all three systems types along with remaining challenges will be presented by some of the field’s leading researchers.

Synopsis. The power generation industry is undergoing a rapid transition. Over the last decade, operational profiles of large, coal fired utility-scale generating units have changed from baseloaded operation to load-following, faster ramping, cycling, and extended standby. Nuclear units, once considered strictly baseload, are now being subject to dispatch commands as well. These new operating paradigms have exposed deficiencies in the units’ design that adversely affect the new operational goals including reliability and efficiency. Some of these deficiencies reside within the instrumentation and control (I&C) system of the unit but even if not logically there, these shortcomings may possibly be cost-effectively ameliorated by I&C enhancements. Solar, wind, and other renewable energy sources are becoming a much larger part of the overall generation fleet. Wind turbines, currently one of the fastest growing renewable energy generators, are complex nonlinear systems containing uncertain parameters, unmodeled dynamics, and are affected by unknown disturbances. On the emerging technologies front, clean coal chemical looping, nuclear fusion, and others are being intensively investigated. This change calls for fundamental advances in the area. With this motivation, the workshop will present models of the current and the upcoming systems, recent progress in their control, and the remaining challenges. It will consist of nine sessions, the first one providing motivation, the next seven presenting recent results, and the last one bringing out the current challenges:
