The installation of Home Energy Systems will become more and more interesting for households or homes due to incentives for self-consumption of in-house generated power by photovoltaic systems or micro combined heat and power plants. The development of Home Energy Systems and residential micro grid concepts can be supported by simulations including detailed load models in order to investigate the efficiency of the applied energy management strategy or control strategy. This work presents a concept to generate realistic load models of individual homes with a high resolution, while reducing the required input information.
