We welcome participation in the International Microgrid Symposium series by highly regarded microgrid experts. Unfortunately, the Fort Collins 2019 Symposium on Microgrids is now full, but email us at the address above. The purpose of the symposiums is to exchange information internationally, yet informally, on the current state of research on microgrids, and to identify key technical, economic, and policy issues that should be addressed by future work. Our goal in Fort Collins is to continue our exchange of results from microgrid research, demonstration, and deployment worldwide with an emphasis on recent results and areas of potential international cooperation. As before, each region will invite eminent speakers to present their work, and there will be additional short summaries of each region’s research program. In addition to these prepared presentations, group discussion will be encouraged. The format of the Fort Collins Symposium will be similar to prior ones. Attendance is by invitation only, and attendees, including speakers, are responsible for their own travel and accommodation expenses. This year’s sessions will be held at the Colorado State University’s Lory Student Center, on Saturday and Sunday, 10-11 August 2019. There will be an optional one-day 12 August 2019 technical tour to the National Renewable Energy Lab (NREL) and The Alliance Center (TAC), both in the Denver area, https://www.nrel.gov/ and https://www.thealliancecenter.org/
