example 1

[0104] The output power of the charging equipment itself is not allowed to exceed 100kW (Pdev). According to the capacity of the two transformers and the long-term stable operation, the charging station monitoring system sets the output active power scheduling plan to a constant value of 900kW (Pt1, Pt2) throughout the day. That is, 24 hours are the same; the operation management system itself has not set a scheduling plan for the charging station, nor has it received the planned scheduling and temporary scheduling issued by the scheduling system, and is in a state of no scheduling.

[0105] In this example, when the following schedule occurs:

[0106] 1. The power dispatching system issues the planned dispatch:

[0107] The power dispatching system issues a dispatching plan to the transformer T1 of the charging station according to the power load demand of the power grid to ensure the safety and reliability of the power line. The content of the sample scheduling plan Plan.T1...

example 2

[0124] The output power of the charging equipment itself is not allowed to exceed 100kW (Pdev); the monitoring system of the charging station is internally set as the all-day output power scheduling plan Plan.T1. and Plan.T2. according to the capacity of the two transformers and the long-term stable operation. A constant value of 900kW (Pt1, Pt2), that is, the same for 24 hours; the charging station monitoring system already has scheduling plans Plan.T1.B0 and Plan.T2.B0 issued by the operation management system, and the current monitoring system is in accordance with Plan.T1.B0 and Plan.T1.CSMS to control the output power of the charging equipment connected to the transformer T1; the operation management system itself has set the scheduling plan Plan.T1., which is in the planned scheduling state. The scheduling content of the current scheduling status is as follows:

[0125] Scheduling period 1: 08:00~08:30 800kW;

[0126] Scheduling period 2: 08:30~09:00 600kW;

Abstract

The invention relates to an electric vehicle charging device and power grid coordinated interaction control system and method. The system comprises: a charging device used for outputting the electric energy of a power grid to an electric vehicle so as to charge the electric vehicle; a charging station monitoring system, wherein thecharging station monitoring system communicates with the charging device and is used for monitoring the working state of the charging device in real time and controlling the output power of the charging device according to an output power scheduling plan and a charging output power demand; an operation management system, wherein the operation management system communicates with the charging station monitoring system and is used for issuing the output power scheduling plan to the charging station monitoring system; and a power dispatching system, wherein thepower dispatching system communicates with the operation management system and is used for monitoring the load state of a power distribution transformer in real time and issuing a charging load dispatching plan to the operation management system in combination with the electrical load demand of the power grid. According to the invention, the output power of a charging station is monitored in real time, so that ordered charging of an electric vehicle and safe and economical operation of a power distribution network are realized, and safe, reliable and stable operation of the load of the charging station is ensured.

Description

technical field [0001] The present invention relates to the field of charging control of electric vehicles, and more particularly, to a system and method for coordinating and interacting between electric vehicle charging equipment and a power grid. Background technique [0002] At present, the problems of environmental protection and energy crisis are becoming more and more serious. Electric vehicles have gradually become the focus of attention of various automobile manufacturers because of their advantages of environmental protection and energy saving. As a supporting facility for electric vehicles, the construction of charging stations is also in full swing. With the large-scale construction of electric vehicle charging stations, the wide application of electric vehicles will lead to a sharp increase in the demand for the use of electric vehicles, which poses a great threat to the safe and stable operation of the local distribution network. As the main component of the fut...
