关于新能源循环利用的研究,电动汽车退化电池的回收是目前亟待解决的重点问题之一,有效结合充电站和梯级利用储能系统,建立基于梯级利用储能系统的电动汽车充电站优化体系。本文结合充电站的电荷原理,系统分析梯级利用储能系统构建和维护的成本、延迟配电系统的升级效益、减少网损的效益和峰谷电价效益,构建梯级利用储能系统的总效益模型,同时借助遗传算法优化该模型。实践证明,将梯级利用储能系统应用于电动汽车充电站,明显降低了变压设备容量,为电力行业创造了一定的经济价值。
As for the research on renewable energy recycling, the recovery of degraded batteries for electric vehicles is one of the key issues that urgently need to be solved. The optimization of charging system for electric vehicles based on the cascade utilization of energy storage system is established by combining the charging station and the cascade energy storage system effectively. Based on the charge principle of the charging station, the system analyzes the cost of constructing and maintaining the energy storage system using cascades, delays the upgrade efficiency of the power distribution system, reduces the benefit of network loss and the peak-valley electricity price, builds the total benefit model of cascade utilization of energy storage system , While optimizing the model with genetic algorithms. Practice has proved that the use of cascade energy storage system applied to the electric car charging station, significantly reducing the capacity of transformer equipment for the power industry has created some economic value.
