Representation of system A and B. System A consists of combined heat and power (CHP) unit, a condensing boiler (B), an immersion heater (IH) and a hot thermal energy storage (HS) providing heating, electricity and gas through the grids. System B additionally contains the cooling grid with a heat pump (HP) between cooling and heating grid, a cooling tower (CT), a compression chiller (CC) and a cold thermal energy storage (CS) (Panten 2019)
