Charging pile access control method based on charging station load real-time scheduling

Abstract

The invention discloses a charging pile access control method based on charging station load real-time scheduling. The control method is characterized by taking an electric-automobile intelligent charging information platform as a carrier; through real-time data of transformer side output power of each cell, a user side electrical load, charging station side output power and the like and electrical load curve data collected and provided by an intelligent power distribution terminal, combining charging pile foundation data, a charging state and other data to carry out integration calculating; calculating a schedulable load in a current time period and a maximum accessible charging amount of the charging pile in an unit charging station within the scheduling period; and considering a real-time load rate in a power supply range of a transformer substation and a number of the charging piles to be charged, and optimally distributing a charging pile access amount of each line. In the invention, problems that whether power distribution network power exceeds a standard can only be statically monitored and a response can not be made in real time currently are solved, and ordered charging ofan electric automobile and safe and economic operation of a distribution network are realized.

Description

technical field [0001] The invention relates to the technical field of charging piles, in particular to a control method for real-time scheduling of charging pile access based on charging station loads. Background technique [0002] At present, the strategy of controlling the orderly charging of electric vehicles has been studied, and all of them are coordinated control of the whole area to achieve the purpose of improving the load characteristics, without considering the connection of regional charging facilities (charging stations or charging piles), grid structure and charging load The effect of distribution cannot actually guide the control process of ordered charging. Moreover, various monitoring terminals are installed in the distribution network to detect the information of the electric meter, but they can only statically know whether the power exceeds the standard, but cannot respond in real time to prevent the power load of the charging station from exceeding the st...

Problems solved by technology

[0002] At present, the strategy of controlling the orderly charging of electric vehicles has been studied, and all of them are coordinated control of the whole area to achieve the purpose of improving the load characteristics, without considering the connection of regional charging facilities (charging stations or charging piles), grid structure and charging load The influence of distribution, can not actually guide the control process of orderly charging

Moreover, various monitoring terminals are installed in the distribution network to detect the information of the electric meter, but they can only know whether the power exceeds the standard statically, but cannot respond in real time to prevent the power load of the charging station from exceeding the standard.

[0003] In actual use, because the access control method of charging piles has very high requirements on the accuracy of the real-time load data and power load curve data provided by the smart power distribution terminal, and the working environment of the smart power distribution terminal is relatively harsh. Problems such as transient electromagnetic interference and communication failure are prone to occur, resulting in the pollution of the data obtained by the access control method of the charging pile, which may lead to wrong control strategies
