Seminar Abstract:

This presentation describes a multi-organization effort to quantify benefits of developing a national high voltage direct current (HVDC) transmission overlay we refer to as a macrogrid, under a high-renewables future. Given the existing “seam” between the North American Eastern and Western interconnections, an infrastructure planning model was developed to assess tradeoffs between investments in cross-seam HVDC transmission, AC & DC transmission needs within each interconnection, generation investment costs, and operational costs, while satisfying different policy compliance constraints. Results indicate that under high wind/solar growth scenarios, the cost of cross-seam transmission is outweighed by generation-related savings it produces. The presence of other macrogrid benefits, including grid reliability, resilience, and adaptability, suggest that cross-seam transmission is a highly attractive infrastructure development strongly in the national interest. We conclude the talk identifying ways to move forward on developing high capacity cross-seam HVDC transmission.

Speaker Bio: Dr. McCalley is an Anson Marston Distinguished Professor and the London Professor of Power Systems Engineering in the Department of Electrical and Computer Engineering at Iowa State University. His research interests are related to electric power systems engineering, including transmission planning, power system security, power system dynamics, wind energy, and long-term investment planning for energy and transportation systems at the national level.

James McCalley received the B.S., M.S., and Ph.D. degrees from Georgia Tech in 1982, 1986, and 1992, respectively. He was employed with the Atlanta Gas Light-Company from 1977-1982 and with Pacific Gas and Electric Company, San Francisco, from 1985 to 1990 as a transmission planning engineer. He has been employed at Iowa State University since 1992. He was elected as an IEEE Fellow in 2003 and was a registered professional engineer in California.
