Problems solved by technology

[0003] At present, the research on the orderly charging of electric vehicles is divided into three categories: grid side, demand side, and combination of grid side and demand side. The main consideration is the impact of the charging behavior of electric vehicles on the power grid, and the existing research is still lacking in how to meet the charging needs of most car owners by changing the charging sequence.

Embodiment 1

[0063] In order to verify the effectiveness and reasonableness of this method, a model of orderly charging of electric vehicles in residential areas was established for analysis and verification. The specific method steps are as follows:

[0064] Assuming that the number of electric vehicles in the residential area is 60, and the number of charging piles is 60, the distribution law of electric vehicle travel is:

[0065]

[0066] The return distribution rule is:

[0067]

[0068] where the parameter of the travel distribution is μ 1 =8,σ 1 =1.3, the parameter of return distribution is μ 2 =18.5,σ 2 =2. Based on the performance of BAIC and BYD brand vehicles with high penetration rate of electric vehicles, the cruising range of electric vehicles is set at 200km, and the slow charging time is 8 hours. The travel mileage distribution of electric vehicles is a uniform distribution of 20-50km.

[0069] Step 1: Update the status of the parking lot, specifically includin...

Abstract

The invention relates to the technical field of charge management of vehicles, in particular to a method for orderly charging an electric vehicle based on TOPSIS sorting. The method includes the stepsof collecting electricity load information, parking lot information and electric vehicle index information in the residential area; monitoring the state of charging piles in a parking lot, and updating the number of available charging piles according to the current residential area load; judging whether the current time belongs to the charging time in the time strategy, setting the number of available charging piles to 0 If it is not a charging period, and sorting the charging sequence of the electric vehicle by the TOPSIS method If it is a charging period; outputting the orderly selection scheme of the current moment so that the charging piles work according to the selection result, and repeating the information collection step for circulation. The method for orderly charging the electric vehicle in the residential area based on the TOPSIS sorting can reasonably arrange the orderly charging of the electric vehicle while ensuring that the load in the residential area does not exceed the limitation, not only improves the completion rate of the charging and saves the charging cost, but also is conductive to an application of the electric vehicle charging in the residential area witha tight distribution power.

Description

technical field [0001] The invention relates to the technical field of electric vehicle charging management, in particular to an orderly charging method for electric vehicles based on TOPSIS sorting. Background technique [0002] In recent years, my country has successively issued incentive policies for electric vehicles, providing certain financial subsidies for the purchase of electric vehicles, and electric vehicles have achieved rapid development. In contrast to the rapid development of electric vehicles, the development of electric vehicle charging facilities and power grid support lag behind, especially in some old residential areas, because the total power limit of the distribution transformer in the early design did not consider the electric In the case of car charging, when a large number of electric vehicles are connected to charge at the same time, the transformer may be overloaded. If the total electricity load in residential areas is limited, there will be situ...
