The invention discloses a V2G-based micro-grid energy storage charging and discharging management method, and aims to solve the problems that in the prior art, the calculation intensity is relatively high, the later maintenance cost is relatively high, the requirement on battery consistency is relatively high, a retired power battery cannot be fully utilized, the inclination state of a charging device cannot be monitored, and the charging efficiency is relatively high. And the safety is low. The management method is used for managing a V2G-based microgrid energy storage charging and discharging system. The system comprises a power grid, a charging terminal, V2G bidirectional charging equipment for providing forward charging and reverse discharging services for the charging terminal, a transformer ammeter for reading real-time electric energy information of an input end of the power grid, and a superior monitoring system in communication connection with the V2G bidirectional charging equipment and the transformer ammeter through the Ethernet. The management method realizes bidirectional charging and discharging, can reduce the power utilization cost of a user, adjusts the power utilization power of the power grid to maintain the output stability, has low requirements on the consistency of the battery, and ensures the safety between the battery and the power grid.

    本发明公开了一种基于V2G的微网储能充放电管理方法,该管理方法旨在解决现有技术下计算强度较大,后期维护成本较高,对电池一致性要求较高,退役动力电池不能被充分利用,并且不能对充电装置的倾斜状态进行监测,安全性低的技术问题。该管理方法,用于管理基于V2G的微网储能充放电系统,该系统包括电网、充电终端、向所述充电终端提供正向充向和逆向放电服务的V2G双向充电设备、用于读取电网输入端的实时电能信息的变压器电表、通过以太网与所述V2G双向充电设备、变压器电表进行通信连接的上级监控系统。该管理方法实现双向充放电,可以降低用户用电成本,调节电网用电功率以维持其输出稳定性,对电池一致性要求低,确保电池与电网之间的安全。
