Residential air source heat pump deployment at scale and UK electricity substation limits during critical cold event
Residential air source heat pump deployment at scale and UK electricity substation limits during critical cold event
This study analyses the potential impact of future widespread UK heat pump (HP) adoption on electricity distribution networks across four scenarios: (1) monthly peak demand analysis, (2) critical cold event analysis, (3) monthly peak demand analysis with thermally upgraded homes, and (4) critical cold event analysis with thermally upgraded homes. The Totton substation near Southampton was taken as the case study. The results indicate that the Totton substation would experience monthly peak-time overload at 20% HP penetration. Thermally upgrading houses can raise this limit to 25%. During critical cold event, switching HPs to continual 24-hour operation mode significantly enhances the hosting capacity of HPs at Totton substation by smoothing peak load demand, which would be increased from 20%-60%. Thermally upgrading houses can further improve this to 70%. The paper highlights the potential importance of demand-side management of HPs when are deployed at scale to support the electricity network.

Abstract
This study analyses the potential impact of future widespread UK heat pump (HP) adoption on electricity distribution networks across four scenarios: (1) monthly peak demand analysis, (2) critical cold event analysis, (3) monthly peak demand analysis with thermally upgraded homes, and (4) critical cold event analysis with thermally upgraded homes. The Totton substation near Southampton was taken as the case study. The results indicate that the Totton substation would experience monthly peak-time overload at 20% HP penetration. Thermally upgrading houses can raise this limit to 25%. During critical cold event, switching HPs to continual 24-hour operation mode significantly enhances the hosting capacity of HPs at Totton substation by smoothing peak load demand, which would be increased from 20%-60%. Thermally upgrading houses can further improve this to 70%. The paper highlights the potential importance of demand-side management of HPs when are deployed at scale to support the electricity network.
