The invention discloses an electric vehicle demand response potential prediction method, which relates to the field of electric vehicle demand response potential prediction, and is characterized in that K-means clustering is carried out on a multi-day charging curve of each user; determining a charging peak time period and a charging valley time period of each user in a single day according to a clustering result, and drawing a charging curve of each user; k-means clustering is carried out on the charging peak time period of each user, the total charging peak time period and the total charging valley time period of all the users are determined according to the clustering result, and the demand response time period of the current electric vehicle participating in peak clipping and valley filling of the power system is set according to the total charging peak time period and the total charging valley time period; and superposing the charging quantity of each user charging peak time period in the time period, and solving the demand response capacity of the electric vehicle capable of participating in peak load shifting of the power system. According to the method, on the basis of factors such as charging time and charging places of different users, potential prediction of large-scale electric vehicle demand response is carried out through K-means secondary clustering.

    本发明公开了一种电动汽车需求响应潜力预测方法,涉及电动汽车需求响应潜力预测领域,其技术方案要点在于:对每个用户的多天充电曲线进行K‑means聚类,根据聚类结果确定出每个用户单天的充电高峰时间段及充电低谷时间段并绘制出每个用户的充电曲线;对于每个用户的充电高峰时间段进行K‑means聚类,根据聚类结果确定出所有用户的总充电高峰时间段及总充电低谷时间段,据此设定当前电动汽车参与电力系统削峰填谷的需求响应时段;将该时段内每个用户充电高峰时间段的充电量进行叠加,求出电动汽车可参与电力系统削峰填谷的需求响应容量。本发明基于不同用户的充电时间、所在的充电场所等因素,通过K‑means二次聚类进行大规模电动汽车需求响应的潜力预测。
