Until lately, the electro-energetic system has operated in a well-established manner, producing electric energy in large production units without any significant difficulties. It has successfully transferred and distributed the energy to end consumers as well. However, an increasingly large part of distributed energy resources and the electrification of heating, cooling and transport have been causing issues with the balancing of production and consumption which is essential for stable network operation. The alternative to the usual network development are smart grids which reduce the pressure on transmission routes through demand response. In this Master’s thesis, heat pump for heating and cooling of business premises have been upgraded with advanced information and communications technologies. Thus, heat pump became active and able to regulate consumption. We evaluated its flexibility potential and observed the effects on spatial thermal comfort. We established that heat pumps can be included in the concept of demand response. Time availability of 12 kW regulation power came to 0.34. We did not detect any deviations in thermal comfort. When determining the suitability for participating in ancillary services, we learned that heat pumps are suitable for secondary and tertiary frequency control. To determine the suitability for primary control, further measurements would need to be performed.
