Abstract: Some works deal with the simulation of the coupling between µCHP systems and buildings but the literature reveals that electric storage systems are poorly integrated inside codes that emulate this coupling. Only Alanne et al. (2010), Bianchi et al. (2013), Cao et al. (2014), Alahäivälä et al. (2015) and Balcombe et al. (2015) incorporated an electrical storage system and none integrates an electrical vehicle. A numerical tool has been developed in TRNSYS to realistically and dynamically simulate the interactions between micro combined heat and power (µCHP) systems, a residential building and the electric grid. This tool includes in particular data driven µCHP models on a gas Stirling engine and a wood pellet Rankine engine, physical models of energy storage systems and realistic 1 min time step stochastic generators energy loads (heat, DHW and electricity). Electrical mobility takes advantage of a possible mutualisation: an electrochemical battery used for an electric mobility application can be regarded as a semistationary storage that is disconnected from the building during travel and reconnected to return. This study shows the relevance of the coupling between electric personal mobility (electric vehicles (EV) or plug-in hybrid EV (PHEV)) and a µCHP electricity production in a joint context and recent growth of these two technologies in France by assessing increases on electrical self-consumption rates, electrical selfproduction rates and electrical coverage rates. Besides, the tool also shows the equivalent full stationary battery that offers EV oversized batteries between 10 and 20 % of the nominal maximum state of charge. The lasting contribution is the numerical platform developed in TRNSYS.
