The invention discloses a photovoltaic-electric vehicle charging station combined control method based on reinforcement learning. The method comprises the following steps: (1) establishing an electric vehicle charging station model; (2) establishing an internal power distribution mechanism of the electric vehicle charging station, preferentially charging the electric vehicles which stay for a short time, and meanwhile, avoiding frequent switching of the charging states of the electric vehicles; (3) electric vehicle and photovoltaic cooperative control is converted into a Markov decision process, and the state, action and reward of the Markov decision process are determined; and (4) performing photovoltaic-electric vehicle charging station cooperative control agent training based on an SAC algorithm, and testing decision precision to realize optimal charging control of the electric vehicle charging station. By using the method, short-term and long-term profits can be balanced in the absence of long-term accurate prediction data, optimal charging control of the electric vehicle power station is realized, and renewable energy consumption is promoted.

    本发明公开了一种基于强化学习的光伏‑电动汽车充电站联合控制方法,包括以下步骤:(1)建立电动汽车充电站模型;(2)建立电动汽车充电站内部功率分配机制,停留时间短的电动汽车优先充电,同时避免电动汽车充电状态频繁切换;(3)将电动汽车与光伏协同控制转化为马尔科夫决策过程,确定马尔科夫决策过程的状态、动作和奖励;(4)基于SAC算法进行光伏‑电动汽车充电站协同控制智能体训练,并测试决策精度,实现电动汽车充电站的最优充电控制。利用本发明,可在缺少长期准确预测数据的情况下平衡短期和长期利润,实现电动汽车电站的最优充电控制,并促进可再生能源消纳。
