The domestic energy model EMOD was developed for the analysis of electricity savings potentials in households promoted by sufficiency and efficiency strategies. Moreover, it is used for the simulation of electricity consumption profiles in households, and of on-site electricity generation from photovoltaics and cogeneration units. The achievable shares of self-generation, or the consequences of self-generated electricity for infeed into the grid can be modelled as a function of a number of parameters. Thus, the proportion of self-generated electricity from photovoltaics on the electricity consumption of households with heat supply by heat pump can be modelled depending on
- appliance efficiency, number of appliances and use pattern
- insulation standard of the building and hot water consumption
- storage volume of heat and electricity storage
- type of heat pump and tax strategies (maximisation of self-generated electricity, etc.)
- number of electric vehicles and drive profile of user
Economic and technological analyses on the consequences of self-generated electricity and use strategies for self-generated electricity on the entire electricity system can be carried out.
