100% Carbon-Free Energy System: Can We Still Keep the Lights On?Date:
Presenter: Dr. Leo Yazhou Jiang, Assistant Professor in the ECE Department at Clarkson University
The recent blackouts in Texas and California have revealed certain vulnerabilities within U.S. energy infrastructure which are not well understood. In particular: (1) a massive winter storm with frigid temperatures caused 4.5 million Texas homes and businesses to lose power for up to 4 days in February 2021; and (2) an extreme heat wave disrupted the power supply to approximately 2 million customers in California in August 2020. These devastating blackouts require action from policy makers, legislators, engineers, and scientists to design and operate more resilient and reliable U.S. energy systems. This seminar will discuss the topic from four aspects: (1) the Texas and California blackouts will be reviewed; (2) generation resource adequacy methodologies will be described and how these resource adequacy programs failed to prevent the blackouts will be analyzed; (3) outage management of distribution systems with smart meters will be discussed; and (4) restoration strategies for bulk power systems in blackouts will be presented. Technology solutions will be discussed to help keep the lights on during the transition to a 100% carbon-free energy system.
Dr. Leo Yazhou Jiang is an Assistant Professor in the ECE Department at Clarkson University. Prior to joining Clarkson in 2020, he was a Power System Engineer at GE Global Research Center located at Niskayuna, NY from 2016 to 2020. At GE, Dr. Jiang led GE Team to investigate long-duration storage for renewable grid integration, and participated in design of GE products including distributed energy resource management system (DERMS), flexible large power transformer, and converter based distributed generation. Due to his contribution to differentiating GE products, Dr. Jiang was awarded the 2018 GE Dushman Technology Excellence Award. Dr. Jiang earned his Ph.D. degree from Washington State University (WSU) in 2016. His research interests include renewable integration and energy digitalization.
