Impact of HP, CHP, PV and EVs on households' electric load profiles
Todays change of technical equipment in private households leads to altered domestic electric load profiles. This work investigates the change of residential electric load profiles when introducing PV, Air-Source-Heat-Pumps, CHP units and electric vehicles (EV). A modular modelling approach is presented, which allows for application on a larger scale, e.g. for simulations of distribution grid or gas and district heating network in residential areas. Results of a one year simulation for a representative German household show that load peaks can vary heavily between 4.05 kW (PV being present) and 24.67 kW (EV being present), i.e. depending on the technology present in a household. The net yearly elctricity demand varies from -1 094 kWh (PV being present) to 14 936 kWh (ASHP being present). This information should be considered when discussing gird planing, energy supply and DSM concepts for residential areas.
