Multi-type charging facility configuration method for residential area

Abstract

The invention relates to a multi-type charging facility configuration method for a residential area. The method comprises the following steps: S1, constructing a residential area electric vehicle charging supply and demand data set; S2, configuring private slow charging piles for the fixed parking spaces, wherein the total capacity of the slow charging piles is Pflow; S3, based on a charging simulation method, obtaining the number Nfast of quick charging piles needing to be configured and the total capacity Pfast of the quick charging piles; S4, if the margin safety verification of the transformer in the residential area is satisfied, entering S6, otherwise, entering S5; S5, correcting the total number of slow charging piles and the total number of quick charging piles configured in the residential area, and returning to S4; and S6, when the charging service rate meets the configuration requirement, outputting a residential area charging facility configuration result. The method has the beneficial effects that the charging service capability is improved under the transformer capacity constraint in a residential area scene, and the method adapts to different permeabilities of electric vehicles.

Description

【Technical field】 [0001] The invention relates to the technical field of power system informatization, in particular to a method for configuring multi-type charging facilities in a residential area. 【Background technique】 [0002] The large-scale promotion of electric vehicles and the replacement of traditional fuel vehicles have become a trend in the world, especially under the background of new carbon targets proposed by governments in this century, electric vehicles with clean and low-carbon performance have been vigorously promoted in many countries around the world , the development of electric vehicles has become a key way to save energy and reduce emissions in the transportation sector. With the development and popularization of electric vehicles, the connection of large-scale charging loads to the power grid will inevitably have an impact on the safety and economic operation of the power grid. The proliferation of electric vehicles as a new technology begins with co...

[0005] Patent application number CN201410001487.5, a patent titled "A Calculation Method for the Configuration Ratio of Fast and Slow Charging Facilities for Electric Vehicles", discloses a calculation method for the configuration ratio of fast and slow charging facilities for electric vehicles; this configuration The method enables the construction of charging facilities to fully meet the needs of electric vehicle users for different types of charging methods, and at the same time ensures the economy of investment in the construction of charging facilities, and avoids the waste of resources caused by the construction of a large number of fast charging facilities; but this patent only considers charging time. Fast and slow charging requirements, not suitable for community scenarios, without considering transformer capacity constraints

Patent application number CN201210222492.X, a patent named "Intelligent Community Power Supply Capacity Planning System and Method Including Electric Vehicle Charging Facilities", discloses a smart community power supply capacity planning system and method including electric vehicle charging facilities; reasonable community The capacity design can avoid the large investment and no-load loss caused by too large transformer capacity, or the increased transformer load loss caused by too small transformer capacity, which will endanger the safety and stability of the power grid; but this patent does not consider multiple types of charging facilities. Consider the limitation of the total power supply capacity of the community, especially for the built-up community or the high penetration rate of electric vehicles, which has poor applicability

Patent application number CN201210042310.0, the patent titled "Regional Electric Vehicle Charging Management System and Method Based on Queue Management", discloses a community electric vehicle charging management system and method based on queue management; it is used to solve the problem of a large number of electric vehicle users The high load technical problem of the power grid caused by charging, the community electric vehicle charging management system and method based on queue management that effectively utilizes the low load of the power grid and meets the service quality requirements of different users; If it does not satisfy the community scenario, it may cause the charging arrangement to deviate from the actual situation
