Research On Distributed Energy System Of Water Source Heat Pump On Vehicle To Building

The interaction and coupling of electric vehicles and energy systems is the main research direction to achieve carbon neutrality in my country in the future.As the mainstream energy system at this stage,distributed energy systems can achieve cascade utilization of energy,but there is still the emergence of waste energy from cold,heat and electricity.In order to effectively solve the problem of waste energy,V2B(Vehicle to Building)and water source heat pump systems are gradually introduced into the distributed energy system.V2 B,as a method of interactive utilization of electric energy,can effectively assist in regulating system power fluctuations;water source heat pump systems can Providing cold energy can also provide heat energy,which can effectively assist the system to adjust cold and heat fluctuations.In this context,this paper proposes a water source heat pump distributed energy system(CCHPWSHP-V2B)operating in V2 B mode,which couples and complements the three,uses economy,environmental protection,and energy saving as evaluation indicators to optimize the system Analysis and adaptability evaluation.This paper first established the CCHP-WSHP-V2 B system model.At the same time,based on the Dalian meteorological data as the data basis for the system load simulation,the CCHPWSHP-V2 B system was simulated with the cooling,heating and power load,and the traditional combined cooling,heating and power generation was used.The system(CCHP)is used as the comparison system,and the production system(SP)is used as the reference system to analyze the operating conditions.Secondly,draw the energy flow equation of the CCHP-WSHP-V2 B system model,take the annual cost saving rate as the optimization goal,and use the typical daily calculation method to analyze the optimal dispatching of cooling,heating and power.The results show that the CCHP-WSHP-V2 B system is compared In the CCHP system,it can effectively solve the problem of cooling,heating and power waste.Through the calculation of the evaluation indicators,it is known that the annual cost saving rate of the CCHP-WSHP-V2 B system is25.47%,the primary energy saving rate is 36.09%,and the carbon dioxide emission reduction rate is 43.06%,which are better than the CCHP system.Finally,the sensitivity analysis of the electricity price,natural gas price,and building category of the CCHP-WSHP-V2 B system is carried out,and the matching schemes for different building types are given based on the annual cost,and the most suitable electric The public transportation coupling scheme provides universal recommendations for the integration of electric buses into the CCHP system.
