Regional power load balancing method

Abstract

The invention relates to a regional power load balancing method. The regional power load balancing method comprises the following steps of: obtaining the actual available power of an electric vehiclecharging station; acquiring the real-time charging power and a power load balancing strategy of the electric vehicle charging station; determining whether the actual available power of the electric vehicle charging station is larger than or equal to the real-time charging power or not, if yes, performing charging according to the opening number and the charging power of the current charging piles,or else, calculating the opening number of the charging piles and the charging power limiting values of the opening charging piles according to the power load balancing strategy; and issuing a dispatching command to the electric vehicle charging station according to the opening number of the charging piles and the charging power limiting values of the opening charging piles obtained through calculation to dispatch the opening number of the charging piles and the charging power of the opening charging piles to achieve the real-time control for the total charging power of the electric vehicle charging station so as to preferentially ensure the normal electricity consumption of resident users.

Description

technical field [0001] The invention relates to the field of electric power load regulation, in particular to a regional power load balancing method. Background technique [0002] With the development of the electric vehicle industry, the demand for charging parking spaces is gradually increasing, and car owners generally charge their electric vehicles in the parking lot of the community. Some old residential areas have limited power distribution capacity, and it is difficult to expand capacity. When there is a peak power consumption period, due to the large number of electric vehicles charging, it is easy to have insufficient power supply. In severe cases, the rated capacity of the transformer may even be exceeded and the control switch In the case of tripping, residents cannot use electricity normally at this time, nor can they charge electric vehicles. Although the new residential area will be equipped with a certain number of charging piles for charging electric vehicle...

AI Technical Summary

Problems solved by technology

Some old residential areas have limited power distribution capacity, and it is difficult to expand capacity. When there is a peak power consumption period, due to the large number of electric vehicles charging, it is easy to have insufficient power supply. In severe cases, the rated capacity of the transformer may even be exceeded and the control switch In the case of tripping, residents cannot use electricity normally and cannot charge electric vehicles at this time

Although the new residential area will be equipped with a certain number of charging piles for charging electric vehicles, if the number of charging piles is large, the power supply capacity that needs to be reserved will also increase accordingly, and the occupancy rate in the initial stage of the use of the community is low. When the number of electric vehicles is relatively small, there will be more additional rental fees paid to the power supply bureau, and the power supply capacity will be redundant

Therefore, whether it is an old community or a new community, the power consumption of each area has a certain limit

[0003] Since the charging power of the currently used charging parking spaces or charging piles cannot be dispatched, when residents’ electricity consumption peaks, if the number of electric vehicles charged is large, the normal electricity consumption of residents cannot be guaranteed, and electric vehicles cannot be charged on demand. , causing trouble for residents to travel
