Problems solved by technology
[0004] Due to its huge advantages in energy saving and emission reduction, electric vehicles have attracted more and more attention, and will gradually enter people's daily life. No matter what charging method is used for huge electric vehicles, the impact on the power grid will be considerable. The influence of harmonics generated by DC conversion on power quality, and the peak-on-peak load of the grid caused by charging during peak hours, etc., if they are allowed to charge disorderly, it will have an adverse impact on the stability and safe operation of the grid

Embodiment Construction
[0046] The present invention is described in detail below in conjunction with accompanying drawing:
[0047] The orderly charging management platform system for electric vehicles in smart parks is based on basic data and real-time data. The effective control of the distribution network load and the statistical analysis of the data of the smart park can realize the orderly charging of electric vehicles in the smart park in an all-round way and with excellent experience.
[0048] The system uses the following supporting technologies:
[0049] 1) HTML5 technology: asynchronous data transmission (HTTP request) is used between the browser and the web server, so that the web page can request a small amount of information from the server.
[0050] 2) Real-time database technology based on Erlang language: used for automatic collection, storage and monitoring of the process, can store the data of each process point online, and can provide clear and accurate operation screens.

The invention discloses an orderly charging system and method for electric vehicles in an intelligent park. Distributed data collection is adopted for multiple charging pile terminals; a load prediction algorithm is called for historical data generated by the collected data to generate load prediction data; the generated load Compare the predicted data with the real load data to form a line chart of the comparison between the load forecast data and the real load data; the hierarchical scheduling with the goal of peak load shifting and valley filling sets the optimization goal of the model, and when performing optimization calculations, the model's goal The function is to make the power purchase cost of the charging station the lowest, and to flatten the load curve; after obtaining the charging power of each period of a single charging station, send the instruction to the charging station, and then the charging station will guide The park is charging in an orderly manner. The protection of the safety and stability of regional power consumption also has important strategic significance for the stability, safety and economic operation of the power system.
Description
technical field [0001] The invention relates to an orderly charging management system and method for electric vehicles in an intelligent park. Background technique [0002] Carry out research on key technologies for orderly charging of electric vehicles in the region, and research on charging piles that support centralized coordination control and harmonic detection. The power grid, promoting the development of the electric vehicle industry, and energy conservation and emission reduction play an important role in promoting. [0003] As the basic energy facilities for the construction of smart parks, the research on the orderly charging of electric vehicles and the support of charging piles for the coordinated control of orderly charging has no norms to follow, and the accumulation of historical data on charging operations in smart parks is basically blank, resulting in a The evaluation of the impact of electric vehicle charging operation on the operation of the regional pow...
