Practice in Differentiated Charging Facility Planning for Urban Areas Based on Simulated Trip Chains of Electric Vehicles
To address the growing disparity in the development scale of urban electric vehicle charging facilities
this paper proposes a differentiated charging facility planning model based on simulated trip chains. Taking Beijing municipality as an example
multi-source data such as vehicle operation
built environment
and charging facilities are integrated to extract user characteristics from time
space
and energy dimensions. And user groups with differentiated characteristics are constructed based on the two-step clustering model of Gaussian mixture clustering and spectral clustering. The potential charging demand distribution network is constructed from a large-scale trip chain and divided into 13 sub-areas with various characteristics by using the community detection algorithm. These sub-areas show differences in charging infrastructure scale
time-of-use pricing
land-use composition
and charging demand hotspot distribution. In view of these differences
the planning model adopts independent construction constraints for various sub-areas and takes the attribute influence factors derived from geographically weighted regression as the weights of the objective function to realize differentiation considerations. The optimized scheme reduces electricity consumption by 3.35% in the areas with oversaturated charging demand
significantly reducing carbon emissions
and the utilization rate of newly constructed charging facilities during peak hours is better than that of old facilities.
