Embodiment Construction
[0016] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0017] Such as figure 1 As shown, the steps of inventing a planning method for electric vehicle charging facilities in residential quarters are as follows:
[0018] (1) Determine the characteristic parameters of the probability distribution of the driving law according to the driving rules of the residents, including: the first driving start time, the last driving end time, and the probability distribution characteristics of the daily driving mileage;
[0019] (2) Determine the number N of electric vehicles, the number N of electric vehicles is determined according to the actual number of electric vehicles in the residential area; and determine the parameters of electric vehicles: including the power consumption characteristics and battery parameters of electric vehicles;
[0020] (3) Establish a queuing charging model, iteratively calculate t...

The invention discloses a method for planning electric vehicle charge facilities in a residential area. The method includes steps of determining charge demand of users and the capacity of each charge facility according to travel laws and charge power of the charge facility; determining the connection position of each electric vehicle charge facility in a power distribution network according to a principle that the influence of electric vehicle charge on voltage of the power distribution network is minimized, and determining the charge capacity of each load point. The method has the advantages that travel and charge behavior of the users are simulated by a Monte Carlo simulation process via a probability distribution model of the travel laws of the users, and the optimal quantity of the charge facilities and the optimal capacity of each charge facility are acquired by means of iterative computation under the condition that the charge demand of the users is met, so that the total capacity of the charge facilities is determined; electric vehicle charge loads are connected into the power distribution network according to the structure of the specific power distribution network, iterative computation is carried out, and a group of optimal node capacity vectors is searched to minimize the influence of access of the electric vehicle charge facilities to the power distribution network, so that joints of the electric vehicle charge facilities and the power distribution network and the charge capacity of each joint can be determined.
Description
technical field [0001] The invention relates to a method for planning electric vehicle charging facilities in residential quarters. technical background [0002] With people's call for low-carbon life, electric vehicles and related technologies have received great attention. In the future, electric vehicles will inevitably be used on a large scale. However, large-scale electric vehicle charging will inevitably cause certain problems to the operation and planning of the grid. Therefore, how to build electric vehicle charging facilities, determine the capacity of the charging facilities, and determine the connection points of the charging facilities in the grid, so that the charging facilities can reduce the impact on the grid while meeting the needs of users, is an urgent problem to be solved. [0003] Existing patents and documents mainly consider the construction method of electric vehicle charging stations. For example, in patent CN102880921A, the charging load distributio...
