N2 - The micro combined heat and power (micro-CHP) enhances the benefits of domestic hot water (DHW) systems. It can not only provide thermal energy but also minimize the need for electricity imports, cutting operating expenses. In DHW systems, the dynamic temperature difference between hot water and ambient causes heat loss in existing structures. However, the dynamic heat losses were ignored in the research on energy scheduling of DHW systems. The dynamic heat losses in a DHW system are calculated in this paper. A novel method for calculating dynamic DHW heat losses based on hot water circulation is proposed. The timetable was then designed to save the daily operation cost. This work shows that the total cost is reduced by 25.1% compared with the unmodified operation plan.
