(57) Abstract: A method for evaluating the acceptance capability of an electric vehicle in a urban distribution network, comprising the 
following steps: 1) on the basis of a trip-chaining theory and a Monte Carlo method, performing electric vehicle charging load prediction 
on an electric vehicle charging load space-time distribution in a target area; 2) by taking into consideration the rationality, reliability 
and economy of a distribution network, setting up a comprehensive acceptance capability evaluation index system; 3) proposing an 
analytic hierarchy process (AHP) and entropy weight method-based comprehensive weighting method for evaluation indices, and using 
9_- a technique for order of preference by similarity to ideal solution (TOPSIS) to evaluate the acceptance capability of the distribution 
network when the charging load is accessed in different ways; and 4) by taking a typical IEEE33 standard distribution network as 
an example for simulation, analyzing the space-time distribution of the charging load in the target area and the impact thereof on the 
distribution network. Simulation results show that when selecting some nodes of the distribution network to access electric vehicles 
in an appropriate amount, the closer the evaluation indices are to an ideal point, and the better the acceptance capability under the 
aforementioned solution.
