Embodiment Construction

[0082] Such as figure 1 and figure 2 As shown, the control method applicable to the orderly charging and discharging of large-scale electric vehicles of the present invention is implemented based on the main control machine of the orderly charging and discharging control center of electric vehicles and the charging and discharging machines within the jurisdiction of the orderly charging and discharging control center. Yes, the main control machine is loaded with an orderly charge and discharge strategy calculation module 7, hereinafter referred to as the strategy calculation module, and the charging and discharging machine is loaded with a charging and discharging pile client program 3, hereinafter referred to as the client, which specifically includes the following steps:

[0083] Step (1): Initialization

[0084] Step (1-1): Initialization of the strategy calculation module of the master computer:

[0085] a) Through the parameter setting module 8 of the orderly charge an...

Abstract

The invention discloses a control method for large-scale orderly electric vehicle charging and discharging. The control method for large-scale orderly electric vehicle charging and discharging comprises the steps that order charging and discharging control strategy calculation is started according to the newest user charging demand information, an overall charging and discharging demand boundary curve and an overall charging load guiding curve of all the electric vehicles connected to charging and discharging machines within the management range of a control center and the charging or discharging power of each electric vehicle are calculated in sequence, the charging and discharging machines are controlled according to the finally determined charging and discharging powers to charge or discharge the electric vehicles, and orderly charging and discharging control is achieved. The control method for large-scale orderly electric vehicle charging and discharging depends on calculation of a simple optimization model, the calculation efficiency is high, the requirement for the hardware environment of the control center is low, calculation resources are effectively saved, the minimization of charging cost can be achieved, and the difference between a load peak and a load valley of a power grid system is improved.

Description

technical field [0001] The invention relates to a control method suitable for orderly charging and discharging of large-scale electric vehicles, belonging to the field of orderly charging and discharging control methods of large-scale electric vehicles. Background technique [0002] Due to its increasingly prominent advantages of energy saving, emission reduction and high efficiency, electric vehicles have received the attention and strong support of governments all over the world. With the large-scale access of electric vehicles to the grid, studies have shown that their disorderly charging will pose a threat to the safe and reliable operation of the grid. For this reason, existing cities in my country, such as Shenzhen and other places, have designed a time-of-use electricity price mechanism specifically for the charging and discharging of electric vehicles to guide electric vehicles to participate in peak shaving and valley filling. On the other hand, EV charging service...
