【摘要】:针对电动公交车光储充电站的运行优化问题,建立了以充电站的运行成本最小为目标、考虑光伏出力随机性的多场景日前优化模型,在满足充电需求的条件下,实现储能系统的充放电优化调度并给出日内储能初始荷电状态。在实时运行阶段,根据更新的光伏和充电需求的预测,提出了光储充电站的日内滚动优化策略。所建模型考虑了环境温度对电动公交车充电需求的影响。仿真结果验证了所提日前和日内优化策略的有效性,并分析了充电站配置光伏和储能系统的成本效益。
[Abstract]:Aiming at the operation optimization problem of electric bus optical storage and charging station, a multi-scene pre-day optimization model considering the randomness of photovoltaic output is established, which aims at the minimum operation cost of the charging station. Under the condition of meeting the charging demand, the charge and discharge optimization scheduling of the energy storage system is realized and the initial charging state of the energy storage system in the day is given. In the real-time operation stage, according to the prediction of the updated photovoltaic and charging requirements, the intraday rolling optimization strategy of the optical storage and charging station is proposed. The model takes into account the influence of ambient temperature on the charging demand of electric bus. The simulation results verify the effectiveness of the proposed pre-day and intra-day optimization strategy, and analyze the cost-effectiveness of photovoltaic and energy storage systems in charging stations.
