摘要
多能源互补的复合充电站模式是解决海岛电动汽车充电问题的有效途径之一。根据海岛地区能源结构特点,提出了考虑投资运营成本和可再生能源利用率的功率分配方案。以油机发电功率、蓄电池组电量、风机组功率、光伏机组功率、系统各部分功率平衡为约束条件建立数学模型,选用带精英策略的非支配排序遗传算法NSGA-II对所构建的模型进行求解。结合具体的算例,获得多组帕累托最优解;选取多组典型优化方案,进行功率平衡分析,验证所构建数学模型的有效性,为多能源复合电动汽车充电站的建设及运营管理提供理论依据和技术支持。
The hybrid charging station model with multiple complementary energy sources is one of the effective ways to solve the problem of island electric vehicle charging.According to the characteristics of energy structure in the island area,the power distribution scheme considering the investment and operation cost and renewable energy utilization rate was proposed.The mathematical model was established with the constraint conditions of oil generator power,battery power,wind power,photovoltaic power and power balance of each part of the system.Nondominated sorting genetic algorithms-II(NSGA-II)with elite strategy was used to solve the model.Combining with a specific example,the Pareto optimal solution was obtained.Several groups of typical optimal dispatching schemes were selected to conduct power balance analysis and verified the validity of the established mathematical model,so as to provide theoretical basis and technical support for the construction and operation management of multi-energy compound electric vehicle charging station.
