Selection optimization of hybrid power gas engine heat pumps

Develops the optimization object function of the hybrid power gas engine heat pump, and selects the parallel-type drive system as the power source. Designs the mixing degree based on the matching relationship of gas engine, motor and batteries, and takes the power hybrid type as the type of mixing degree. Taking the payback period as the object function, obtains the optimum value of mixing degree is 0.27 for the power hybrid type gas engine heat pump.
