Abstract:

In the context of "dual carbon", integrated energy systems are continuously promoting the technological reforms in the fields of flexible renewable energy consumption, low-carbon heating and cooling, industrial waste heat utilization and flexible and coordinated peak shaving for the power grid. Heat pumps are widely used in integrated energy systems because of their high efficiency and low pollutant emissions. Being the energy supply or energy storage unit in an integrated energy system, heat pumps can be divided into four categories according to their energy sources, air source, water source, soil source and waste heat recovery heat pumps. Heat pumps can be heat (cold) storage and electricity storage units according to their functions. Heat pumps can facilitate the low-carbon and high-efficiency operation of the system, but arise problems from energy coupling and optimal operation. Finally, the development trend of heat pumps in integrated energy systems is prospected.

Key words: integrated energy system, heat pump, energy supply, energy storage, energy matching, optimized operation, "dual carbon" target
