The invention discloses an electric vehicle charging and discharging load curve prediction method, system and device and a medium. The method comprises the steps that the charging amount of an electric vehicle is obtained; the method comprises the following steps: acquiring electricity price original data, inputting the acquired electricity price original data into a pre-trained XGBoost, Attention-LSTM and random forest RF fusion model, performing weighted summation on predicted values output by the XGBoost, Attention-LSTM and random forest RF, and outputting a final electricity price predicted value; and obtaining a charging load curve of the electric vehicle based on the obtained charging amount and the electricity price prediction value of the electric vehicle. According to the method, the influence of the electricity price on the charging load is considered, different electric vehicle numbers, daily average mileage and electricity price are adjusted, charging load curves under different conditions are obtained, and the method is high in flexibility.

    本发明公开了一种电动汽车充放电负荷曲线预测方法、系统、装置及介质,包括:通过获取电动汽车的充电量;采集电价原始数据,并将所采集的电价原始数据输入预先训练好的XGBoost、Attention‑LSTM和随机森林RF的融合模型中,将在XGBoost、Attention‑LSTM和随机森林RF输出的预测值进行加权求和,输出最终的电价预测值;基于所获取的电动汽车充电量和电价预测值,获取电动汽车的充电负荷曲线。本发明考虑电价对充电负荷的影响,调整不同电动汽车数量、日均里程和电价,得到不同情况下的充电负荷曲线,方法灵活度高。
