The Applied Energy Symposium and Summit, REM2018: Renewable Energy Integration with Mini/Microgrid was held in Rhodes, Greece, on September 28 to 30, 2018. More than 80 participants from over 23 countries in different regions, who provided 94 scientific presentations, attended this conference. The REM2018 provided a perfect platform focused on mini/microgrid architecture and design, energy storages for mini/microgrid applications, mathematical modelling and analysis of mini/microgrids with intermittent renewable generation, 100% or high penetration renewable energy systems, forecasting, modeling and optimization of variable renewables, policy and regulatory interventions for renewable energy mini/microgrid systems, and new utility business models. The event consisted of a two-day symposium for sharing the most recent progress of research in renewable energy integration with mini/microgrid. A field study tour was also arranged to visit a renewable energy project in Tilos island organized by the University of West Attica. The conference organisation was supported by TILOS project (Horizon 2020 Low Carbon Energy Local / small-scale storage LCE-08-2014).
