Embodiment Construction

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

[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 peak charging period of electric vehicles is roughly in the time period from 16:00 to 19:00, which roughly coincides with the evening peak time after get o...

Abstract

The invention discloses a load regulation and control method and system considering the safety state of a charging facility, and a storage medium. The method comprises the steps: building a constraintcondition of a power grid load; and regulating and controlling the power grid load according to the constraint condition. Guidance and load control of charging and discharging behaviors of an electric vehicle can be realized according to electric charging and discharging rules.

Description

technical field [0001] The invention belongs to the technical field of electric power, 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 electric vehicle to grid (V2G: Vehicle-to-grid) technology has been proposed to guide the system that sells 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 t...
