The stochastic nature of renewable energy sources, such as wind and solar, introduces a new form of uncertainty in power system operation. A standard answer to concerns about this increase in uncertainty is that the system should become more “flexible”. However, there is as yet no agreement on exactly how much flexibility is needed or even a commonly accepted measure of flexibility. However, there is agreement on the fact that flexibility has a cost and that this cost should be minimized in a way that does not affect reliability or the ability to integrate renewable energy sources. This presentation will explore the short-term (i.e. operational) and long-term (i.e. investment) aspects of providing flexibility using conventional generation sources, storage and demand response.
Daniel Kirschen was recently appointed to the Close Professorship in Electrical Engineering at the University of Washington. His research focuses on smart grids, the integration of renewable energy sources in the grid, power system economics and power system security. Before joining UW, he taught for 16 years at The University of Manchester (UK). Before becoming an academic, Daniel worked for Control Data and Siemens on the development of application software for utility control centers. He holds a PhD and MS from the University of Wisconsin-Madison and an Electro-Mechanical Engineering degree from the Free University of Brussels (Belgium).
