Optimisation systémique de micro-cogénérateurs intégrés au bâtiment

Abstract : Micro-cogeneration systems appeared on the market in the last decades. They are recognised and stimulated in numerous countries as a mean of reducing the energy consumption and the green house gases emissions of buildings. In France however, their introduction and sustainability on the market is restrained by their economic and environmental analysis not yet precisely assessed, and by the fact that the technology is unknown from the architects and contractors. Thus, a numerical model that could be integrated in dynamic building and systems simulation software is created. A detailed experimental campaign conducted on a Stirling-based gas fired micro-cogenerator enabled a simplification of the model by means of a selection of the relevant parameters. That way, an identification procedure with few parameters has been designed. It reduces the experimental needs to calibrate the model, but preserves the models validity, thanks to the modelling of physical phenomena and the use of thermodynamic properties found in the literature. The calibrated and validated model has been integrated in a numerical tool for simulating micro-cogeneration systems coupled to buildings. The thermal needs of the building, for heating and hot domestic water purposes, as well as its electrical needs have been modelled. The building thus modelled has been coupled with the micro-cogenerator and a thermal storage. A cost function that associates energetic and environmental performances has been defined. This permits the optimisation of the sizing and operation of the building-integrated system.
