摘要: 为研究一类以动力电池和超级电容为复合电源的有轨电车参数匹配问题,提出一种基于多目标优化的复合电源参数设计方法。根据有轨电车的动力性能需求,给出基于等效计算的复合电源参数设计方法。以有轨电车日均运行成本和动力电池的性能衰减率为评价指标,建立多目标优化函数,采用带精英策略的非支配排序的遗传算法(NSGA-Ⅱ),设计系统仿真模型在环的复合电源参数优化流程。以一次往返行程为运营要求,对比分析两个不同工况的Pareto解集和等效计算配置方案下的有轨电车系统仿真结果。结果表明,相比等效计算的配置方案,优化的配置方案使动力电池性能衰减率降低至少约31.1%;合理的配置方案可有效保证较高的再生制动能量回收率和有轨电车效率;长站间距的工况增加了对复合电源的配置需求。

Abstract: In order to study the parameter matching problems of a tram powered by hybrid energy storage system which consists of a battery pack and an ultracapacitor pack, a parameter matching approach of hybrid energy storage system is proposed based on a multi-objective optimization algorithm. According to the dynamic performance requirement of the tram, a design of hybrid energy storage system' parameters is presented based on equivalent calculation approach. The multi-objective cost function is established by using the daily operating cost of the tram and performance degradation rate of battery as performance indicators. The optimization process of hybrid energy storage system with system simulation model in loop is designed by using NSGA-Ⅱalgorithm. Taking a round trip as operation requirement of the tram, the simulation results of different parameter matching of Pareto solution set and equivalent calculation approach are compared and analyzed in two different drive cycles. The simulation results indicate that the optimized result reduces the performance degradation rate of battery by at least 31.1%, compared with the parameter matching result of the hybrid energy storage system based on the equivalent calculation approach. Moreover, the reasonable configuration of hybrid energy storage system can effectively guarantee the high recovery rate of regenerative braking energy and the efficiency of the tram, and the longer distance between stations increases the configuration demand of the hybrid energy storage system.
