Automized, Simulation-Based, Technical and Economical Rating of Semi-Self-Sufficient Electrical Energy Systems

While houses were simply connected to the electrical grid and contained a gas or oil heating system, for a long time energy flows were simple. With the integration of alternative energy systems such as photovoltaic (PV) systems, heat pumps, combined heat and power units (CHPs), home batteries and electrical cars into houses, energy flows become more complicated. This paper describes the implementation of a model to simulate the technical and economical outcome of a system with the previously mentioned components in single- and multi-family houses in Germany. As input for climate data and energy demand, literature data is used. The simulation is capable of economic and ecologic estimation and can be controlled by a web interface with the intention to provide a straightforward online tool for homeowners.
