Performance of the Sendai Microgrid During the 2011 Earthquake and Tsunami

March 23, 2012 - 12:00pm
Seminar Host/Point of Contact: 

This seminar provides an overview of the Sendai Microgrid, and outlines its behavior during the earthquake and its aftermath. On March 11, 2011, an earthquake of unprecedented violence occurred in the Tohoku region, along Japan’s Pacific Coast. The extremely intense vibrations severely damaged electric utility facilities, and the subsequent tsunami washed away many coastal towns and villages. The Sendai Microgrid at Tohoku Fukushi University, located northwest of downtown Sendai, had been built and demonstrated over the four years beginning in 2005. The Microgrid was funded under an empirical microgrid research program supported by Japan’s New Energy and Industrial Technology Development Organization (NEDO). Although the demonstration was officially completed in March 2008, operation of the microgrid has been continued, and some minor changes have been implemented. The catastrophe of March 11 caused a lengthy power outage in many areas of the Northeast, but the Microgrid, using its distributed generators and batteries, maintained continuous power supply. This campus specializes in medical practitioner training, and some of its facilities, including a hospital, nursing care facilities, and a data center were supplied with power as well as heat heat generated by the microgrid’s thermal generators.   A recording of this seminar is available at:
