Abstract
Buildings that are able to shift their loads without comfort restraints are important
for the ongoing transformation of the power supply. This flexibility potential can be expressed
in flexibility factors. The usefulness of four factors is investigated based on load control for the
heat pump of a small apartment building according to electricity prices (high/low tariffs, spot
market prices), CO2eq emissions share in the grid and a restricted operation period during
daytime. The calculation methodology of the presented flexibility factors GSC, RIP, FF and FI
is very different. RIP and FF are preferable because they have defined valid ranges which
makes them easier to understand. Current electricity prices force the heat pump operation
mainly into the night. The optimization of CO2eq emissions encourages operation mainly during
the day. The optimization goals costs or CO2eq emissions thus lead to opposing heat pump
operation times and can currently therefore not both be met simultaneously.
