A workshop on Microgrid Systems and Power Electronics for Low Energy Buildings, held on March 29-30, 2015 in the new ECE building, addressed renewable energy systems and their integration into electricity grids and buildings. It was sponsored by the Mid-America Microgrid Education and Training Consortium (MARMET), the Power Sources Manufacturers Association, the IEEE Power Electronics Society Emerging Technologies Technical Committee, the IEEE Central Illinois Section, and the IEEE joint student chapter on power electronics and power and energy systems. Papers presented addressed low-energy buildings, power grid stability, distributed generation, grid and thermal energy storage, effects of regulatory and utility policy, modeling solar costs and sensitivity, local voltage control, and lessons learned through a microgrid test bed. Forty-three participants attended MARMET, including representatives from Ameren, Iowa State, Missouri S & T, University of Wisconsin-Madison, University of Arkansas, Dave Bodenshatz, lead engineer for ECEB from KJWW (Quad Cities), and the University of Illinois.
