摘　　要：为了提高混合储能系统(HESS)的效率和生命周期,设计了一种基于分时算法的新型能量管理策略,其可以优化HESS功率流控制以适应系统约束。传统的HESS能量管理策略以超级电容的参考电压为运行约束,以防止其过度充电或充电不足,这导致了超级电容电压利用范围较窄。而实际上超级电容的电压安全变化范围较广,故新型能量管理策略将分时算法用于超级电容的充放电控制,并引入电压带,从而增大了HESS能量传输能力,同时提高了动态性能且减小了超级电容规模,因而提升了HESS经济性。最后,利用HESS实验平台开展了不同运行条件下的能量管理测试,实验结果验证了新型能量管理策略的效果。In order to enhance the efficiency and life cycle of the hybrid energy storage system(HESS),a kind of novel energy management strategy based on time-sharing algorithm is designed,which can optimize HESS power flow control so to adapt to system constraints.The traditional HESS energy management strategy uses the reference voltage of the super capacitor as the operating constraint to prevent it from being overcharged or undercharged,which results in a narrower utilization range of super capacitor voltage.In fact,however,the safe variation range of voltage of the super capacitor is wider,therefore the new energy management strategy applies the time-sharing algorithm for charge and discharge control of the super capacitor and introduces the voltage band,thus increasing the energy transmission capacity of the HESS and,at the same time,improving the dynamic performance and reducing the size of the super capacitor and therefore improving the economic performance of the HESS.Finally,the energy management tests under different operating conditions are performed by the use of HESS experimental platform,and the result of the new energy management strategy is verified by the experimental result.
