Research and Analysis on the Performance of Linkage Operation of Heat Pump Energy Storage and Photovoltaic Coupling System
With the low-carbon development of buildings,renewable energy technologies such as heat pumps and photovoltaics are gradually being applied on a large scale in building energy systems.However,their disorderly application will bring significant pressure to the distribution and carrying capacity of the power grid.This paper proposed a"heat pump+energy storage+photovoltaic"cold,heat and power coupled building energy system,which adopts the source grid load storage linkage operation method.By orderly adjusting the operation status of photovoltaic,distribution network,heat pump,and energy storage,it achieves low-cost cooling and heating for buildings,promotes local consumption of renewable energy generation,and balances power grid scheduling.At the same time,this paper verified the application effect of the source network load storage linkage operation method through a simulation platform.The results showed that using the source load storage linkage operation method,on typical days of partial load in winter,the local consumption of renewable energy increased by 24.13％,the overall operating cost of the system decreased by 34.10％,and the peak power shift increased by 27.60％compared with the heat pump direct supply operation method.On typical days of partial load in summer,local consumption of renewable energy increased by 21.47％,system operating costs decreased by 33.20％,and electricity peak shifting increased by 21.11％.The local consumption of renewable energy in the energy system increased by 22.47％throughout the year,operating costs decreased by 33.59％,power peak shifting increased by 15.95％,and the static investment recovery period of the system was 4.67 years.The paper demonstrates that the"heat pump+energy storage+photovoltaic"system adopts a source grid load storage linkage operation method,significantly saving system operating costs,promoting local renewable energy consumption,and balancing the power grid.The research results can be used to guide engineering applications.
