Embodiment Construction

[0016] In conjunction with the accompanying drawings, an orderly charging method for an electric vehicle charging station of the present invention includes the following steps:

[0017] Step 1. Obtain the battery capacity of the electric vehicle and the current state of charge of the battery; at the same time, collect the expected residence time of the charging control system of the customer in the charging station and the expected SOC level of the electric vehicle when the customer leaves

[0018] Step 2. According to the charging demand and system operating status, formulate the time-of-use electricity price; specifically:

[0019] Determine the T that the system will stop at the car from the current time period i In a period of time, the charging load margin M t (t=1,2,...,T i ) is greater than P i the number of H i :

[0020] h i =|A i |, A i ={t|M t ≥P i ,t=1,...,T i}

[0021] Among them, |A i |for set A i the number of elements within;

[0022] If H i i...

Abstract

The invention discloses an orderly charging method of an electric vehicle charging station, comprising the following steps: firstly, acquiring the charging demand of the electric vehicle through a battery management system on the electric vehicle; Then according to the charging demand and the system running state, the time-sharing price is made, and the charging plan is determined by the user independently corresponding time-sharing price. Finally, Monte Carlo algorithm is used to simulate the user charging demand, and the load of distribution transformer, operating economic benefit and user's charging cost of electric vehicle charging station are predicted under the two conditions of orderly charging and disorderly charging. On the basis of comprehensively considering the charging demand of the user and the load level of the electric network, the orderly charging method of an electric vehicle charging station takes peak clipping and valley filling as the goal, adopts the heuristic algorithm to dynamically solve the time-sharing price period of the electric vehicle of the intervening charging station, and the user responds independently, which can be used for the orderly chargingcontrol of the charging station of the large-scale electric vehicle.

Description

technical field [0001] The invention belongs to the field of smart grids, in particular to an orderly charging method for an electric vehicle charging station. Background technique [0002] In recent years, the global energy crisis has become increasingly prominent, the harm of air pollution and global temperature rise has been increasing, and people's attention to energy and environmental issues has also been increasing. Automobiles are an important means of transportation for people, and traditional vehicles mainly provide energy supply in the form of fuel, and most of them have the disadvantages of high energy consumption and high pollution. While promoting economic development, the traditional automobile industry has also exacerbated the problems of energy shortage and environmental degradation. To alleviate the increasingly severe energy crisis and air pollution problems, it is necessary to vigorously develop energy-saving and clean vehicles in the transportation indust...
