摘要
现代有轨电车混合储能系统的关键问题在于制定高效科学的能量管理策略,其结果可以实现储能元件之间的合理功率分配,影响各个储能元件的性能。文中提出一种改进的新型能量管理策略,根据有轨电车的实际需求,采用带有能量互补的恒定功率比例能量管理策略,对混合储能系统分配负载功率。以系统总质量最小为目标进行容量优化,用Matlab进行算例仿真分析,结果表明,提出的能量管理策略优化了超级电容的工作状态,减轻了系统的质量,能使混合储能系统提供足够的牵引功率并吸收列车的制动能量,可以满足列车的功率需求。
The key problem of modern tram hybrid energy storage system is to formulate efficient and scientific energy management strategy,which can achieve reasonable power distribution among energy storage elements and affect the performance of each energy storage element.An improved new energy management strategy is proposed.According to the actual demand of the tram,a fixed power proportional energy management strategy with energy complementarity is adopted to allocate load power to the hybrid energy storage system.The minimum total weight system as the optimization target capacity,the simulation analysis with Matlab for example results show that the proposed energy management strategies to optimize the working state of the supercapacitor,to reduce the weight of the system,can make the hybrid energy storage system to provide enough traction power and absorb the train braking energy,can satisfy the power demand of the train.
