Aggregated load curves estimation in presence of asynchronous individual meter data. (Estimation de synchrones de consommations électriques avec calage dynamique sur des données de relevés d’index asynchrones.) (French. English summary) Zbl 1316.62016

Summary: The French Company Electricité de France needs to estimate as precisely as possible the electricity consumption at an aggregated level at an half-hourly timestep. These estimations are carried out based on customers samples and can be enhanced by using individual metering data collected every six months (every month in the near future) for each client of the population. However, these metering data are gathered for billing purposes so the metering does not occur simultaneously for all the population. For this reason, we cannot apply directly the usual calibration techniques so, in this article, we propose to adapt them to our context where we estimate an aggregated curve using an asynchronous auxiliary information evoluting over time. The performances of our methods will be assessed on a real dataset.
