Embodiment Construction

[0056] see figure 1 , is a flowchart of a method for planning electric taxi charging stations based on demand analysis provided by an embodiment of the present invention.

[0057] Such as figure 1 As shown, the demand analysis-based electric taxi charging station planning method provided by the embodiment of the present invention includes:

[0058] S100: Initialize the basic data required for planning, the basic data includes the coordinates of traffic nodes in the planning area, the number of taxis in the area during shift shift time periods, and the historical demand for taxis in the area, calculate the total load of the area according to the basic data and predict Estimate the value range of the number of charging stations.

[0059] Specifically, according to the basic data of the planning area, the total charging demand of the planning area is Q total , the maximum capacity of the charging station is limited to S max , the minimum capacity is limited to S min , accord...

Abstract

The present invention discloses an electric taxi charging station planning method based on demand analysis. The method comprises the steps of: employing a cluster analysis method and a P-median modelto perform analysis of demands of taxis in a region, and determining construction distribution sites of charging stations in the region; and employing a logit model to simulate probability behaviors of the taxis selecting the charging stations, employing a queuing theory model to calculate average queuing waiting time of each charging station, and determining one construction scale of each charging station according to the average queuing waiting time of each charging station. The charging station planning method based on the demands of electric taxis employs the P-median model to perform optimization addressing of the distribution sites of the charging stations and employs an M/G/c model, configured to more accurately reflect charging features of the taxis in the stations, in the queuingtheory to solve the charging station capacity configuration problem so as to determine a charging station optimization planning scheme, and therefore the method provided by the invention is effectiveand practical.

Description

technical field [0001] The invention relates to the technical field of electric vehicle charging station planning, in particular to a method for planning electric taxi charging stations based on demand analysis. Background technique [0002] With the continuous improvement of my country's economic and social development level, the number of car ownership continues to rise. Vigorously developing electric vehicles can speed up fuel substitution and reduce vehicle exhaust emissions, which is of great significance for ensuring energy security, promoting energy conservation and emission reduction, and preventing and controlling air pollution. Prioritizing the promotion of electric vehicles in public service areas such as public transport, rental, sanitation and logistics is an important way to achieve green travel, and a sound charging infrastructure system is an important guarantee for the popularization of electric vehicles. [0003] Electric taxis have a wide range of operatio...
