Novel control strategy and modeling of air source heat pump for consuming PV power

Abstract

The rapid development of PV power generation has led to numerous problems of system operation and PV power consumption. As a new type of heat pump, the air source heat pump has advantages of energy saving, environment protection and good flexibility. In this paper, PV generation power during generation peak time is consumed by air source heat pumps to produce and storage heat. First, this paper establishes a basic thermophysical model of air source heat pump and analyzes the method of using air source heat pumps to consume PV generation power. Second, a control strategy for consuming PV generation power by clustering air source heat pumps with different parameters is proposed. Then, a multi-objective scheduling model of air source heat pumps is presented. Finally, NSGA-II is used to solve the multi-objective model, and the corresponding Pareto optimal solutions are obtained. The simulation results show that the model proposed in this paper can well follow the PV generation output, reduce the PV power curtailment and heating cost of users.
