Embodiment Construction

[0048] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to more clearly illustrate the technical solutions of the present invention, and cannot limit the protection scope of the present invention with this.

[0049] Based on the statistics of the usage habits of electric vehicle owners, the present invention establishes a mathematical model of the peak-valley time-of-use charging and discharging electricity price strategy, and adopts the Bayesian method to optimize the time-of-use electricity price scheme, thereby realizing the guidance of the charging and discharging behavior of electric vehicles and load control.

[0050] Statistics show that in the absence of any guidance strategy for charging and discharging behavior of electric vehicles, the charging peak period of electric vehicles is roughly in the time period from 16:00 to 19:00. Normal distribution trend.

[0051] In order to gu...

Abstract

The invention discloses a load control method, system and storage medium considering the safety state of charging facilities. The method includes: establishing a constraint condition of the grid load; and regulating the grid load according to the constraint condition. The invention can realize the guidance and load control of the charging and discharging behavior of the electric vehicle according to the law of electric charging and discharging.

Description

technical field [0001] The invention belongs to the field of electric power technology, and in particular relates to a load control method, system and storage medium considering the safety status of charging facilities. Background technique [0002] With the increase in the penetration rate of electric vehicles, the technology of V2G (Vehicle-to-grid) has been proposed to guide the system of selling the electric energy of the vehicle battery to the grid when the electric vehicle is not in use. At present, there are several pilot systems at home and abroad. [0003] Considering the normal distribution characteristics of the usage habits and usage time of electric vehicle owners, according to the natural charging law of rechargeable electric vehicles, it is very likely that the capacity of the regional power grid will be insufficient, which will affect the stability of the regional power grid. A large number of electric vehicles are naturally connected to the power grid as el...
