摘要：The control strategy for a coaxial parallel hybrid-power gas engine-driven heat pump system is studied based on instantaneous optimization, aiming at minimizing the equivalent energy consumption. The system includes two main subsystems, drive subsystem and heat pump subsystem. Continuously variable transmission (CVT) is applied to combine the two subsystems for a continuous transmission ratio adjustment. The steady-state models of components of the two subsystems are established, and based on which equivalent energy consumption function is proposed. Meanwhile, a penalty factor is introduced into study of battery to maintain SOC in range of 0.2 to 0.8, where the internal resistance is relatively small. Then computational simulation work is performed on Simulink platform. Result shows that battery SOC runs stable between 0.49~0.66 and equivalent energy consumption is 10.4% lower than that of system with multi-stage gear ratios.
