Innovation: what if a solar farm alone provided ancillary services?

EDF Store & Forecast has enabled the optimization of Le Fouilloux solar farm located in France for its client EDF Renouvelables. The facility has been designed to provide ancillary services to the grid by dynamically controlling the production output through the project’s inverter. This breakthrough is particularly innovative given the intermittent nature of energy production from solar projects.

EDF Store & Forecast has developed an integrated software solution that combines optimal inverter regulation and advanced solar production forecasting. The solar farm, made up of 10 MW of photovoltaic (PV) panels and located in the French region of Nouvelle Aquitaine is able to dynamically adjust its electric production to follow ancillary services signals.
This multi-criteria adjusting ability allows the owner to provide ancillary services to the grid (frequency regulation, voltage control, active power smoothing) in addition to energy production. This achievement shows that, in some specific cases, intermittent renewable resources can reliably provide ancillary services even without batteries. For each project, EDF Store & Forecast’s expertise is able to establish the optimal set up of its clients’ installations.
This PV solar farm was developed and built by EDF Renouvelables, one of the winners of CRE call for tenders for project developers and operators of photovoltaic production facilities above 250 kWp including innovative components.
