Embodiment Construction

[0032] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings, but the present invention is not limited to these embodiments.

[0033] The basic idea of ​​the present invention is to consider the minimum time length constraints of electric vehicle i in each charge and the minimum time length constraints of electric vehicle i in each discharge in the two-way charge and discharge control model, so as to prevent frequent charge and discharge and improve battery life. life.

[0034] Based on the above idea, the embodiment of the present invention proposes a bidirectional charging and discharging control method based on V2G technology, such as figure 1 shown, including the following steps:

[0035] S1: Consider the constraints of the minimum time length of electric vehicle i in each charge and the minimum time length constraints of electric vehicle i in each discharge to establish a bidirectional charge-discha...

Abstract

The invention relates to the field of energy management, in particular to a bidirectional charging and discharging control method based on the V2G technology, and the method comprises the following steps: S1, building a bidirectional charging and discharging control model through considering the minimum time length constraint condition of an electric vehicle i during each charging and the minimumtime length constraint condition of the electric vehicle i during each discharging; S2, acquiring working parameters of each electric vehicle, and solving the bidirectional charging and discharging control model to obtain the charging and discharging quantity pgrid(t) of the electric vehicle at each t moment. In the bidirectional charging and discharging control model, the minimum time length constraint condition of the electric vehicle i in each time of charging and the minimum time length constraint condition of the electric vehicle i in each time of discharging are considered, frequent charging and discharging are prevented, and the service life of the battery is prolonged.

Description

technical field [0001] The invention relates to the field of energy management, in particular to a bidirectional charging and discharging control method based on V2G technology. Background technique [0002] In recent years, with the popularization of V2G (vehicle to grid) electric vehicles, great opportunities and challenges have been brought to the grid system. Since electric vehicles have charge and discharge functions, unreasonable charge and discharge will have a great impact on the battery life of electric vehicles. economic benefits. But existing technology does not maximize battery life. Contents of the invention [0003] In order to solve the above problems, the present invention proposes a bidirectional charging and discharging control method based on V2G technology. [0004] A bidirectional charging and discharging control method based on V2G technology, comprising: [0005] Consider the constraints of the minimum time length of electric vehicle i in each ch...
