The invention provides a comprehensive integrated optimization design method for a pure electric bus network, and the method comprises the steps: formulating a comprehensive integrated optimization design framework for the pure electric bus network from the perspective of global optimization, and achieving the comprehensive design scheme of the layout planning of the bus network, the setting of departure frequency and the site selection of a charging station; starting from the perspective of bus network operators, systematically analyzing the operation process of the pure electric bus network,extracting main operation cost involved in the method, establishing a pure electric bus network comprehensive integrated optimization design model taking minimum total operation cost as a design target on the basis of the main operation cost, reducing financial burden of a government by effectively controlling the operation cost, and effectively meeting carrying requirements of regional bus passenger flow; and constructing a new model calculation method on the basis of an artificial fish swarm intelligent algorithm framework to provide a more efficient solving thought for solving the problemof the optimal design of an actual-scale urban pure electric bus network.

Description

technical field [0001] The invention relates to the technical field of pure electric public transportation, in particular to a method for comprehensively integrating and optimizing design of pure electric public transportation network. Background technique [0002] At present, there are few researches on the optimal design of pure electric bus network at home and abroad, and most of these studies analyze the layout planning of the bus network, the setting of departure frequency and the location of charging stations as separate issues, without considering the overall situation. From the perspective of optimization, a comprehensive integrated optimization design framework for pure electric bus network is formulated. From the point of view of the theoretical model, the existing research does not fully consider the high operating costs caused by the use of pure electric buses and the construction of charging stations when constructing the calculation objectives of the optimal de...

This is because the battery capacity of different sizes will directly affect the cruising range of pure electric buses; in this regard, Kunith et al. and Rogge et al. are committed to optimizing the battery capacity of fast charging facilities and pure electric buses at the same time; Charging infrastructure, i.e. cost competitiveness between charging stations, battery swap stations and charging lanes; although analyzed the impact of the use of pure electric buses on the optimization research of bus network layout planning, departure frequency setting, and charging facility location selection, etc., but each optimization research is carried out in stages one by one, and it is difficult to obtain the global optimal design scheme; Iliopoulou et al. established a two-layer optimization model to conduct research on the optimal design of the bus network layout and fast charger site selection, and then used the heuristic algorithm based on the particle swarm optimization algorithm framework to solve the established optimization model.
