Modélisation multiphysique des flux énergétiques d’un couplage photovoltaïque-électrolyseur PEM-pile à combustible PEM en vue d’une application stationnaire

Abstract : A stand alone multi-source system based on the coupling of photovoltaic energy and both a PEM electrolyser and a PEMFC for stationary application is studied. The system gathers photovoltaic array as main energy source, ultracapacitors and batteries packs in order to smooth respectively fast and medium dynamic by supplying the load or by absorbing photovoltaic source overproduction. Because of the necessity of fuel availability, especially for islanding application like this one, a PEM electrolyser is integrated to the system for in situ hydrogen production.The main purpose being modeling and management of the power flows in order to meet the energy requirement without power cut, a graphical modeling tool namely Energetic Macroscopic Representation (EMR) is used because of its analysis and control strengths. Thanks to the modular feature of the EMR, the different models of each energetic entity of the system are performed before their assembling.By using scale effect, the energetic system sizing is performed according to a household power profile. Then, by the help of the multi-level representation, the maximal control structure (MCS) is deduced from the system EMR model. The electrical reference values of the MCS are generated by applying the power balancing method involving the own dynamic of each source into the energy management strategy. Different behavior modes are taken into account. By considering an irradiance profile for one day, the system is simulated highlighting its suitable behaviour. Moreover, the relevance of the introduced coupling between fuzzy logic controller and the power balancing method is pointed out.
