💥1 概述

近年来我国电动汽车行业飞速发展，其中电动汽车入网技术（vehicle-to-grid，V2G）在中国新电力系统和能源互联网中是成本较低、规模较大、安全性能较好的一项新兴技术，成为未来发展的趋势。由于当前V2G技术不够成熟，试点项目较少，用户参与V2G的放电行为特征数据和V2G参与电力市场的案例分析较少。

本文开发了一种算法来调度使用充电站的500辆电动汽车（EV），以使充电成本最小化，同时，随机调度任意少量的电动汽车行驶到指定的房屋负载，在那里放电并返回充电站。模拟测试了三种不同的场景——首先，客户满意度（即电动汽车车主满意度）被认为是从放电中赚取的钱和在充电中花费的钱之间的总差异，其次，客户满意度与第一种场景相同，但减去模拟结束时未完成充电的总成本，第三，客户满意度考虑了放电利润、充电成本、未完成充电总成本以及在整个模拟过程中从每辆电动汽车切换的成本。
