Our study concerns the electricity supply of a meteorological weather pylon with help of a PV/H2 hybrid system in Cadarache (Aix in Provence, France). The objective was to determine the optimal sizing of the whole system by observing his capacity to answer to the specifications and taking into account the appropriate constraints for the site. This approach has been made via a new numerical sizing code (Matlab language), based on a sequential running time. For the simulation, a good precision of the balance between production and consumption is obtained with a time-step of one hour. This time scale allows neglecting the response time of the various sub-systems. This approximation is realistic because we do not want to get an accurate electrical comportment of the system in real time, but we search to obtain a global evaluation of the energetic balance during the time of each simulation. The system consists of renewable sources of production energy (PV array), energy storage system (H2 chain) and converters which are associated with them. The objective of this program is to define a whole of systems able to satisfy the request of the load.
