Ordered charging and discharging control method and system based on transformer area intelligent fusion terminal

Abstract

The invention discloses an ordered charging and discharging control method and system based on a transformer area intelligent fusion terminal, and belongs to the technical field of ordered charging and discharging interaction control of charging piles. The method comprises the following steps: generating a transformer area day-ahead charging and discharging load plan according to the analysis of historical operation data through the historical operation data of a charging and discharging load and other loads of a power distribution transformer area collected by a transformer area intelligent fusion terminal; for the day-ahead charging and discharging load planning of the transformer area, according to the non-real-time optimization strategy of the charging and discharging load of the power distribution transformer area, determining the intra-day charging and discharging load planning of the transformer area, so that a charging and discharging load scheduling strategy of a power distribution master station is formed; and according to the charging and discharging load regulation and control strategy of the power distribution main station and the real-time charging and discharging load optimization strategy in the transformer area, orderly charging and discharging control executed by the actual issuing charging pile is formed. According to the invention, the fine level of adjustment and control of the electric vehicle charging and discharging facility by the distribution automation terminal is improved.

Description

technical field [0001] The present invention relates to the technical field of interactive control of orderly charging and discharging of charging piles, and more specifically, relates to a control method and system for orderly charging and discharging based on an intelligent fusion terminal in a station area. Background technique [0002] The application of pure electric new energy vehicles can effectively reduce the use of fossil energy, promote emission reduction and ultimately achieve the goal of carbon neutrality. With the rapid increase in the number of electric vehicles, problems such as difficulty in charging in public places, some old communities, and rural areas have become more prominent. The demand for charging in some public places and official vehicles is also growing rapidly. At present, some old residential areas, rural areas, and public places have limited distribution transformer capacity, which is difficult to meet the needs of electric vehicle charging. ...

AI Technical Summary

Problems solved by technology

[0003] At present, most of the charging piles in residential areas are piles without communication and regulation. They cannot be connected to the platform for operation, and it is difficult to accept orderly charging and discharging regulation. At this stage, the data information of charging facilities is poor in real-time and interconnection. The compatibility of facilities is poor. At present, the main station system usually controls the orderly charging of electric vehicle charging facilities based on the charging load forecast data.

The above control methods are difficult to meet the safety and stability level of electric vehicles connected to the distribution network and the requirements of lean control of charging and discharging loads
