V2G模式下的电动汽车充放电控制思路探究与讨论

Exploration and Discussion of Electric Vehicle Charging and Discharging Control Ideas in V2G Mode

电动汽车属于动态负荷,充电行为的随机性较强,对电网具有较大影响。当电动汽车大规模无序充电的过程中,在很大程度上降低了电网运行的安全可靠性。因此,人们要积极探索科学有效的控制措施,控制电动汽车有序充放电,改善相应区域电网的负荷特性,确保电网运行的稳定性、经济性。基于此,本文首先对V2G技术进行了阐述,然后分析了V2G双向充放电装置的基本结构,提出相应的控制策略,最后深入探究V2G控制系统的设计。

Electric vehicles belong to dynamic loads,and the charging behavior is more random,which has a greater impact on the power grid.The process of large-scale disordered charging of electric vehicles reduces the safety and reliability of power grid operation to a large extent.Therefore,people should actively explore scientific and effective control measures to control the orderly charging and discharging of electric vehicles,improve the load characteristics of the corresponding regional power grids,and ensure the stability and economy of power grid operation.Based on this,this paper firstly elaborates on V2G technology,then analyzes the basic structure of V2G bidirectional charging and discharging device,puts forward the corresponding control strategy,and finally explores the design of V2G control system in depth.
