Droop Control of Heat Pumps in Integrated Electricity and District Heating Systems in Remote Community Microgrids

This paper proposes a droop control of Heat Pumps (HPs) in Integrated Electricity and Heating Systems (IEHSs) to manage energy exchanges between these networks to provide frequency regulation services in microgrids. Thus, demand management control of HPs is proposed to enhance primary frequency regulation, which facilitates the integration of variable Renewable Energy Sources (RESs). The developed droop control is applied, tested, and validated in a realistic community microgrid based on a remote community Electric Power Network (EPN) located at Kasabonika Lake First Nation (KLFN) in Northern Ontario. It is shown that the District Heating Network (DHN) facilitates the proper integration of RESs in isolated microgrids.
