The invention provides an orderly charging and discharging method of an electric bus based on a time-of-use electricity price. The method comprises the following steps: acquiring electrical load dataof each time period of a local area from a power grid; judging a charging type of each electric bus, wherein the charging type includes the type of not accepting charging and discharging scheduling, the type of accepting ordered charging scheduling and the type of accepting ordered charging and discharging scheduling; on a power grid side, taking a minimum load wave crest and valley difference asa target function; at an electric bus operator side, taking minimum electric bus charging cost as the target function; and establishing an optimization model by taking a battery capacity, operation time and charging and discharging power of the electric bus as constraint conditions, and obtaining the optimal charging and discharging time and power by solving the model. According to the method, thepeak-valley difference of the power grid load can be adjusted, losses of the power grid caused by disordered charging of the load are reduced, and reliability of power grid operation is further improved. Based on a time-of-use electricity price policy, the electric bus is controlled to carry out orderly charging and discharging so that charging cost is reduced.

    本发明提供了一种基于分时电价的电动公交车有序充放电方法,其包括以下步骤:从电网获取本地区的各个时段的用电负荷数据;判断各电动公交车的充电类型,充电类型包括不接受充放电调度、接受有序充电调度、接受有序充放电调度;在电网侧,以负荷波峰谷差最小为目标函数;在电动公交车运营商侧,以电动公交车充电费用最少为目标函数;以电动公交车的电池电量、运营时间和充放电功率为约束条件建立优化模型,通过求解模型得到最优的充放电时刻和功率。本发明的方法可以调节电网负荷的峰谷差,降低负荷无序充电对电网造成的损耗,进一步提高电网运行的可靠性。基于分时电价政策,控制电动公交车进行有序的充放电,从而降低充电成本。
