Characterization of grid-oriented control of heat pumps via SG-Ready

The integration of heat pumps into energy systems is critical for decarbonisation, with growing installations necessitating their alignment with power grid demands. Heat pump penetration poses challenges for low-voltage grids, such as voltage drops and overloading, while technologies like the SG-Ready interface offer the potential for flexibility and grid-oriented control. However, gaps persist in experimental validation and high-resolution analyses of heat pump behaviour. This study evaluates the dynamic response of two heat pumps using field measurements with 0.2s resolution, focusing on SG-Ready state changes. By openly sharing our dataset, this study advances research on practical applications of grid-oriented control. Results reveal rapid, predictable responses during blocking events but significant variability during start-up, limiting simultaneity in grid operations.
