摘要: 以电力大用户参与电力市场交易为背景,研究电动公交车光储充电站通过代理商参与月度电力交易的优化问题。基于实际电动公交车充电站的充电历史数据,提出了电动公交车代理商参与月度市场双边交易的优化模型,该模型考虑了充电站内光伏发电和充电负荷的随机性;提出了最小化偏差电量惩罚的充电站日运行优化策略与实施方法,通过控制充电站内储能系统充放电策略减小月度合同的偏差损失。算例结果表明,所提出的模型和策略可给出代理商月度交易的优化方案,并可显著减少合同偏差电量、降低惩罚费用。

Abstract: This paper works on the problem of monthly electricity transaction optimization for the electric bus charging stations with solar power and energy storage through an agent, with regard to large electricity consumer participating the monthly electricity market. On the basis of the historical charging records of some actual electric bus charging stations, an optimization model for the agent of electric bus charging stations to participate in the monthly market bilateral transaction is proposed. The randomness of PV generation and the charging demands are taken into account in the model. An optimal dispatch model and implementation method are proposed to minimize the deviation penalty of the monthly contract via the charging and discharging schedule of energy storage system within electric bus charging station. Simulation results show that the proposed models and strategies can effectively provide the monthly optimal transaction decision of the agent and significantly mitigate the deviation penalty between contract and actual electricity consumption.
