A multi-vector community energy system integrating a heating network, electricity grid and PV production to manage an electrified community

•An energy system integrates heating grid, EV smart charging, peak shaving, solar PV.•The demand ratio of DHW to SH defines the supply temperature of the heating network.•The electric peak demand can be reduced from over five time increase to 33%increase.•A model identifies the required degree of housing thermal efficiency improvement.•A modelling tool indicates energy system requirements and hourly electricity demand.
