PV/H2 Hybrid System Sizing - The PEPITE Project
Résumé
PEPITE (Study And Experimentation of Intermittent Energy Management using Electrochemical Technologies) is a project endorsed by the French PAN-H research program (action plan on hydrogen and fuel cell) supported by the ANR (French Research National Agency). This project concerns, among other tasks, a demonstration of the electricity supply of a weather station with help of a PV/ H2 hybrid system in Cadarache (Aix in Provence, 43°31′52″N 5°27′14″E, France). This paper describes the optimization method of the whole system sizing, considering a predefined load profile, via observing his ability to meet the specifications taking into account the appropriate constraints of the site. This approach has been made via a new numerical sizing code named ORIENTE (Optimization of Renewable Intermittent Energies with hydrogeN for auTonomous Electrification) under Matlab software.. The system is composed by a renewable source of energy (solar radiation with a PV array), an energy storage system (H2 chain and battery pack) and converters which are associated to them. This article presents optimal sizing curves for the PV/ H2 hybrid system in relation to the predefined load and the energy system balance for LLP = 0 (Loss of Load Probability). These results, determining the size of each subsystem etc.),P,V,V,(PFCO2H2PV will allow to build the best energy flows regulation mode.
