A home energy management system (HEMS) for residential buildings is investigated regarding its load shifting potential. A photovoltaic system, temporally shiftable electrical devices, different heat producers (heat pump, condensing boiler), electrical and thermal storages and an electric car as well as varying building configurations are considered. In order to calculate this system simulations are carried out using SimulationX to emulate the residential environment and its devices as well as Matlab and GAMS to implement the optimization with the focus of minimizing costs and grid purchases. The simulation results show an increase of degree of autarky and self-consumption and a reduction of costs at the same time.     «
