The resolution drives the conclusion: insights from low-energy co-housing measurements

Consumption patterns of electricity by residential customers are rapidly changing through the uptake of PV systems, new large consumers such as heat pumps and electric vehicles. The emergence of digital meters give distribution system operators (DSOs) and households a more detailed look at these consumption patterns. These meters provide a standard time resolution of 15 min for remote access, while higher resolution data (e.g. 1 s) can be captured through physical access to the meter. In this work, electricity consumption measurements at 1 s resolution have been captured at a low-energy co-housing community for analysis. The load profiles from these households give insights into future demand patterns and are compared against 15 min data of Flemish households. The importance of time resolution is shown to affect the magnitude and timing of peak loads during the year and day, which is of importance for DSOs and households to make appropriate investment decisions for battery storage and grid upgrades.
