Example Embodiment

[0024] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0025] An example of the present invention provides a random access control system for electric vehicle charging loads, the system architecture is as follows figure 1 As shown, it includes a charging strategy controller and multiple smart charging piles connected to it. The charging strategy controller has the functions of information receiving and processing, and issuing control instructions, wherein the information receiving and processing functions are used to receive the electricity price and load information of the day, read the load forecast results of the day before, and formulate charging during the next day's valley period accordingly. Rules; the function of issuing control commands sends the determined charging rules to each smart charging pile, so that each charging pile starts and stops according to the rules, and realizes order...

Abstract

The invention relates to an electric vehicle charging load random connecting control system and method of charging pile self-decision, and belongs to the field of electric vehicle intelligent charging. The system comprises a control decision generator and a plurality of intelligent charging piles. The control decision generator obtains the electricity price and load information of a current control area, calculates the probability distribution of corresponding charging start moments of users of different charging time durations according to a load curve by means of the designed random connecting method, and issues control instructions to all the intelligent charging piles, and the charging piles determine the final charging start time according to the probabilities of the connecting users.The method has a good peak-load shifting effect, can restrain the power grid load fluctuation and reduce the charging cost of the users of electric vehicles; the whole control process is independently completed by the device in the control area, concentrated type communication and control are not needed, implementation is simple and convenient, and the system is low in cost and suitable for orderly charging of residential areas with large-scale private electric vehicles.

Description

technical field [0001] The invention belongs to the field of intelligent charging of electric vehicles, and relates to a control system and method for random access control of charging loads of electric vehicles with self-decision-making of charging piles. Background technique [0002] Today, as energy and environmental issues are becoming more and more prominent, electric vehicles are attracting more and more attention as a clean new energy transportation tool. As the penetration rate of electric vehicles continues to increase, problems also follow. Due to the lack of necessary control methods in the power grid system, when the peak period of electricity consumption arrives, a large number of electric vehicles will be charged out of order and will cause a huge impact on the power grid. Leading to overloading, threatening the safety and stability of the power grid. If the capacity of power equipment is specially increased to cope with peak power consumption, it will increas...
