Grid support coefficients for electricity-based heating and cooling and field data analysis of present-day installations in Germany

A new method for assessing the grid interaction of a building’s electricity consumption and generation is presented. It consists of the Grid Support Coefficients GSCabs and GSCrel. GSCabs “weights” the electricity consumption profile with a time-resolved reference quantity which expresses the availability of electricity in the public grid (here: stock electricity price, residual load, cumulative energy consumption or fraction of wind and PV in the electricity mix). GSCrel relates GSCabs to the worst and best achievable values on a scale of −100 to 100 in order to increase the comparability of the results.
