Together with Siemens the city of Vienna is developing and testing smart and digital applications with a focus on the domains of smart buildings and smart grids. Multiple buildings of the city of Vienna are or were operated by b.eos as part of the R&D program Aspern Smart City Research (ASCR). Goal is the operation of the electric energy system with minimum operation costs. 
For this project the three use cases apply. Self-Consumption Optimization (SCO): Using the generated PV power in a cost-optimal way, considering a limit for grid feed-in as well as dynamic feed-in prices. Grid Charge Reduction (GCR): Minimized monthly peak power costs. Day-Ahead Optimization (DAO): The battery is operated in a cost-optimal way based on a PV generation forecast, el. base load forecast and dynamic tariffs for grid demand and feed-in. GCR and DAO: Optimized grid demand based on dynamic day-ahead electricity prices. 
Depending on the month, the monthly peak power costs can be reduced up to 30%. The generated PV power is used in alignment with feed-in limit. PV system is curtailed to avoid negative electricity prices. Depending on the electricity prices (dynamic consumption and feed-in prices), the electric heaters use surplus power, if this is cost-optimal. 
Aspen is a smart city district at the outskirts of Vienna where the city of Vienna, together with Siemens, is developing and testing smart and digital applications with a focus on the domains of smart buildings and smart grids.
