Simulation analysis of typical household heating systems based on peak and valley time price policies
In view of the implementation of clean heating and the peak-and-valley time-of-use electricity price policy in Mengxi area of Inner Mongolia.In order to explore the optimal system and the operation time composition of the peak and valley period.This paper takes a residential house in Baotou,Inner Mongolia as the research object,and uses TRNSYS to build three kinds of heating system models based on peak and valley time:electric boiler heating system,solar heating system with electrically aided heater and air source heat pump heating system.And comprehensive economic evaluation will be judged by the three factors of initial installation cost,operating cost,equipment maintenance.The results show that the composition of peak and valley power operation time about electric boiler,solar with electrically aided heater and air source heat pump heating system are 3:7,2:8 and 3:7 respectively.The comprehensive economic efficiency of air source heat pump heating systems has become prominent at the third year;and solar heating systems became higher than direct heating electric boilers at the seventh year.It is recommended that air source heat pump heating system was the best option,direct heating electric boilers be the second.This result provides practical reference value for the implementation of the"coal to electricity"plan in the future.
