Grid Flexible Control of Heat Pumps

---

Within the EU project Flexible Heat and Power (FHP), RISE Research Institutes of Sweden has, together with the other project partners, evaluated the possibilities and limitations for external control of today’s and
tomorrow’s heat pumps. This in order to control the power consumption, as well as providing demand response.
Both indirect control, via temperature sensor override, and direct control of the compressor speed has been evaluated by laboratory tests of a ground source heat pump. Direct control gives the best accuracy, while indirect control works on more or less all heat pumps.
