5 Energy and grid transformation Microgrid participation Microgrid Distributed energy resources and loads that can be operated in a controlled, coordinated way either connected to the main power grid or in islanded * mode. Microgrids are low or medium voltage grids without power transmission capabilities and are typically not geographically spread out. Power grid Power grids are larger conventional and spread out grids with high voltage power transmission capabilities. Microgrid technology can be applied to weak grids making the network more robust. Nanogrid Low voltage grids that typically serve a single building. Microgrid technolog can be applim ABB Group October 10, 2016 Slide 5 Islanded mode: ability to provide power independently from the main power grid

6 Microgrid technology solutions PowerStore Power Conversion with Virtual Generator Scalable from 100 kva cabinet to 5 MVA* containerised solution Overload capability of up to 200% of rated power. Operate as voltage source with virtual generator functionality *Continuous rating
