Embodiment Construction

[0038] The present invention will be further described below in conjunction with the drawings and embodiments.

[0039] Select a residential area or park as an example scenario.

[0040] This collaborative scheduling method involves the acquisition of neighborhood information. First, a day is divided into T time periods according to control requirements, and each time period is divided into two parts, the current operation and the next stage plan, such as figure 2 Shown.

[0041] This collaborative scheduling method involves the acquisition of neighborhood information, including the equivalent load P of the power generation and consumption objects within a certain radius of the neighborhood. E,j (t), the total capacity of distribution transformers or switches in the neighborhood P N,j , This example selects the living residential district or park as the scene, so it can be considered that the total capacity of the distribution transformer in the neighborhood is P N,j It is the tota...

Abstract

The invention discloses a neighborhood information-based cooperative scheduling method for scattered charging piles. Charging pile objects change charging status flags at the beginning of a t time period according to a plan made in the previous time period; and charging piles acquire power generation information and power consumption information of current other objects within a certain radius of a neighborhood, calculate charging probability thresholds in a t+1 time period by combining the condition whether a cooperative scheduling flag is received or not, compare the charging probability thresholds with a random number generated at random and make a decision whether charging is carried out or not. According to the neighborhood information-based cooperative scheduling method, layering is not needed, coordination between an upper layer and a lower layer is not needed and the algorithm structure is simple. The scheduling method is suitable for the characteristics that the charging piles are wide in distribution and small in capacity; the investment in a scheduling system can be reduced; and more flexible configuration is achieved.

Description

Technical field [0001] The invention belongs to the field of electric vehicle charging pile charging control, and in particular relates to a neighborhood information-based coordinated dispatching method for decentralized charging piles for grid peak shaving and valley filling. Background technique [0002] At present, fossil fuels, mainly coal and petroleum, are widely used, causing air pollution to become increasingly serious. Electric vehicles have received great attention from governments and enterprises all over the world for their good environmental protection and energy saving characteristics. Charger technology and battery manufacturing technology have been improved year by year, and the construction of charging facilities has accelerated, which has promoted the rapid growth of electric vehicles and realized low-carbon and environmentally friendly transportation. [0003] However, when large-scale electric vehicles are connected to the grid for charging at the same time, th...
