Promoting the replacement of auxiliary power unit（APU）in aviation airports is an important measure in the construction of green airports. APU replacement at remote locations is affected by power distribution capacity expansion and transformation and safety restrictions. The program of APU alternative to configurating photovoltaicstorage system is proposed. Firstly

the APU replacement load characteristic model is established based on the flight dynamics. Secondly

bilevel optimization model is proposed considering the configuration of photovoltaic storage system under dynamic load characteristic. The outer model considers the optimal cost of photovoltaicstorage system

and the inner model takes into account the operation of energy storage. Finally

the inner model is transferred to the additional constraint of the outer layer by the KKT condition of inner model

the bilevel model is transferred into a mix integer linear programming. The validity of the proposed scheme is verified by summer and winter flight data of a civil aviation airprt

and the rationality of the APU replacement of the airport’s remote aircraft site by the optical storage system is analyzed.
