Introducing Energy Storage’s Electrochemistry to Power System Dispatch Applications

Integration of unpredictable renewable generation reduces the control capabilities of power system operators to cost-efficiently mitigate related uncertainty. This project explores the effectiveness of battery energy storage as an affordable, reliable, and controllable resource to compensate for energy imbalances caused by renewable generation. In that regard, this project couples an electrochemistry model of the battery storage and a power system dispatch tool, which simultaneously enables minimizing the cost of the electricity supply and avoiding unnecessary operations and, thus, degradation of battery storages. This model is used to compare the payback of long-term capital investments in battery storages with different chemistries and to reduce the cost of large-scale integration of renewable generation. The findings of this project include the least cost selection of battery chemistries for different penetrations of wind and solar generation, or their combination.

The Washington Research Foundation has provided a six-year gift of $6.74 million to support nine new faculty hires, six postdoctoral researchers and the creation of a new experimental manufacturing facility on campus that will help move discoveries from the laboratory to the marketplace. This investment in the CEI is truly transformational.”

“Providing clean energy to the inhabitants of our planet is a major challenge to future generations. The University of Washington is to be congratulated for establishing an Institute where faculty and students can work together to tackle the difficult global challenge of energy sustainability.”
– Mildred Dresselhaus, Professor of Physics and Electrical Engineering, Emerita and Institute Professor, Massachusetts Institute of Technology
“Energy competition is opening up in a variety of ways, the push for carbon control will continue, and the rate of technology advancement is exponential. All the things I’ve seen at the CEI are just perfect for the way we see things going in energy. You guys are at the cutting edge. We’re counting on you.”
– Ronald Litzinger, President, Edison Energy
Since its founding the Clean Energy Institute has contributed more than $1.1 million toward the education of 66 STEM scholars and recruitment of 12 students through our fellowship programs.
