摘要
新能源汽车的发展能够有效地改善环境污染,为了提供更安全、高效的充能服务,提出了一种多目标能量优化调度方法。文中首先定义了新能源汽车一体充能站的概念,建立风、光、氢、储、新能源汽车一体充能站模型,并进行结构分析以及运行策略分析。然后,针对含有风力发电系统、光伏发电系统、电动汽车快充装置、制氢、储氢、充氢装置的新能源汽车充能站建立优化调度模型,兼顾电动汽车充电需求与氢燃料汽车的充氢需求,以综合运行成本与蓄电池组循环电量为目标函数,采用NSGA-Ⅱ算法对多目标优化问题进行求解,并给出充能站各组件的优化调度方案。最后,对优化结果进行分析并与常规调度方案进行对比可以看出优化调度方案具有明显优势。
The development of renewable energy vehicle can effectively improve environmental pollution. Aimed to provide safer and more efficient charging services, a multi-objective energy optimal dispatching method is proposed. Firstly, the concept of integrated charging station for renewable energy vehicle is defined, and the model of integrated charging station with solar-wind-hydrogen-storage energy and renewable energy vehicle is established and analyzed in structure and operation strategy. Then, an optimal dispatching model is built for the renewable energy vehicle charging station including wind power generation system, photovoltaic power generation system, fast charging devices of electric vehicle, hydrogen production storage and charging devices. Considering the charging demand of electric vehicle and hydrogen fuel cell vehicle, the multi-objective optimization problem is solved by using NSGA-Ⅱ algorithm, whose objective functions are the integrated operation cost and the battery cycle capacity. The optimal dispatching scheme of each component of the charging station is given. Finally, the optimization results are analyzed and compared with conventional dispatching schemes, which shows that the optimal dispatching scheme has obvious advantages.
