Study on the Configuration of Clean Energy Substitution for APU in Green Airport

It is an important problem for green airport construction to replace the assist power unit (APU) aviation fuel with electric energy during aircraft docking. This paper proposes the rational allocation of photovoltaic-storage system to solve its electricity demand, which not only solves the problem of power distribution network expansion caused by fuel substitution, but also effectively reduces the aviation fuel consumption. By analyzing the electric energy demand under the dynamic change of aircraft flight, the power supply model of the photovoltaic-storage system is constructed, and the optimization model based on economy is established to achieve the goal of optimal investment cost of optical storage and electric energy replacement cost respectively, and the operating life characteristics of energy storage are considered. Cplex algorithm was used to solve the problem. The feasibility of the proposed algorithm is proved by verifying the flight operation scenarios of a civil aviation airport in summer and winter.
