基于CROA的智能电网电动汽车有序充放电策略研究

A Strategy of Ordered Charging and Discharging of Electric Vehicle in Smart Grid Based on CROA

针对电动汽车的使用会使用户支付大量的用电费用,本文在考虑电动汽车充放电功率约束及可用容量约束的前提下,建立了实时电价体系下电动汽车有序充放电数学模型,并采用化学反应算法对电动汽车在各个时间窗口的充放电功率进行了优化。结果表明,对电动汽车进行有序充放电可以使用户每天最多获利15元,减少了用户支付的用电费用,甚至从中获得利润。该研究为下一步优化大规模电动汽车充电站的运行模式奠定了理论基础。

Electric vehicle users need to pay a lot of electricity costs by charging from the grid and the peak and valley price is more and more popular, so the ordered charging and discharging strategy can be considered to reduce the electricity costs or even make the users get some profit from it. A mathematical model of ordered charging and discharging of electric vehicle under real-time pricing is built. Considering the constraints such as charging and discharging power of the electric vehicle and its available capacity, the proposed mathematical model is solved by chemical reaction optimization algorithm. The results indicate that the ordered charging and discharging strategy can make the users get 15 yuan at most oae day and prove that the ordered charging and discharging strategy can reduce the electricity costs or even make the users get some profit from it.
