Research on Load Characteristics and Demand Response Control Model of River Water Source Heat Pump System

The energy utilization of river water source heat pump system adheres to the principle of “one energy, multipurpose and multi energy cooperation”, fully excavates the water resources of the park, comprehensively utilizes other clean energy, runs coordinately, and constructs a green, low-carbon, safe and efficient energy system. From the perspective of energy transfer, river water source heat pump system is a bridge connecting water source side and load side. The characteristics of water intake temperature and load distribution on the water source side have an important impact on the energy efficiency of the river water heat pump system. For example, the cooling load of residential buildings in summer is 78684kW, which can be reduced by combining water source heat pump with demand response. In this paper, the characteristics of water temperature change and load distribution on the demand side are analyzed. According to the load characteristics of different buildings, the demand response control model is established, and the user comfort is fully considered, which lays the foundation for the river water source heat pump system to participate in the demand response.
