SimulationX Green Building is a flexible simulation environment for quick and reliable modeling, calculation and analysis of building and district energy systems. Power, heat and in particular coupled networks: fit generation capacity, transmission paths and storage accurately to various usage scenarios Usage scenarios 1. Plan: Energy System Simulation with Green Building 2. Test: Testing Platform for PLC-control systems with Green Building toolchain 3. Improve: Energy Monitoring and Optimization with Green Building toolchain E-Mobility: Considering energy systems as a whole, electric vehicles will become an essential part: as an energy consumer, storage and source. Examine the influence of recuperation in your power grid. Use electric vehicle fleets as mobile energy storage and adjust the charging time to the available power. Likewise, charging stations with their own energy supply can be quickly and clearly modeled, simulated and analyzed with SimulationX.
