Abstract

The widespread adoption of electric vehicles and electric heat pumps would result in radically different household electrical demand characteristics, while also possibly posing a threat to the stability of the electrical grid. In this paper, a micro-trigeneration system (composed of a 6.0 kWel cogeneration device feeding a 4.5 kWcool electric air-cooled vapor compression water chiller) serving an Italian residential multi-family house was investigated by using the dynamic simulation software TRNSYS. The charging of an electric vehicle was considered by analyzing a set of seven electric vehicle charging profiles representing different scenarios. The simulations were performed in order to evaluate the capability of micro-cogeneration technology in: alleviating the impact on the electric infrastructure (a); saving primary energy (b); reducing the carbon dioxide equivalent emissions (c) and determining the operating costs in comparison to a conventional supply system based on separate energy production (d).

Keywords: Cogeneration, Trigeneration, Electric vehicle, Energy saving, TRNSYS, Carbon dioxide emissions.
