Embodiment

[0071] This embodiment provides a method for planning an electric public transport system, such as figure 1 shown, including the following steps:

[0072] The first step is to collect bus network and operation data of each line in the network. Collect bus line site information, empty driving time between sites, and line operation timetable information by consulting the bus company or consulting relevant websites. Among them, the site information of the bus line mainly includes the number of parking spaces, supporting facilities, and power grid conditions at the first and last stations of each line in the line network, and then evaluates and screens the sites that can be equipped with charging facilities. The information on the idling time between stations can be obtained through field tests or through the online map API by using the number of crawlers, and is used for the calculation of vehicle scheduling or charging idling scheduling. The line operation timetable informatio...

Abstract

The invention relates to an electric public transportation system planning method. The method comprises the following steps: obtaining public transportation network information and cost information; establishing an electric bus network operation scheduling and charging facility layout optimization model taking the minimum total cost of the electric bus system as a target by utilizing the bus network information and the cost information; and solving the electric bus network operation scheduling and charging facility layout optimization model by using an adaptive genetic algorithm of the continuous change crossover probability and the continuous change mutation probability to obtain an electric bus system related to electric bus network operation scheduling and electric bus charging facilitylayout. Compared with the prior art, an electric bus operation scheduling plan and a charging facility layout scheme are optimized at the same time, the method can be suitable for time-of-use electricity price, the utilization rate of electric buses is increased, electric bus charging scheduling is more flexible, off-peak charging can be achieved, the electricity consumption cost is reduced, andthe utilization rate of the electric buses and charging facilities is increased.

Description

technical field [0001] The invention relates to the field of public transport systems, in particular to an electric public transport system planning method. Background technique [0002] The bus system is one of the ideal application scenarios for pure electric vehicles due to its fixed routes and timetables. Electric buses have the characteristics of low noise, zero emissions, and high comfort. They are generally considered to replace traditional diesel buses and are the future development direction of the public transportation system. [0003] However, due to the limitations of battery technology, electric buses have limited battery life and long charging time. The operation and scheduling of electric buses need to consider not only the scheduling of vehicles, but also the scheduling of charging vehicles. In addition, the layout of charging facilities is also a key problem in the electrification of public transport, and the layout of charging facilities and the operation ...
