摘要
针对单储能系统的不足,介绍了一种混合储能系统(HESS)的能量管理办法。该方法发挥了蓄电池与超级电容器性能互补的优势,利用低通滤波算法对系统波动功率进行分配,使超级电容器与蓄电池分别吸收或释放波动功率中的高频分量与低频分量,优化了蓄电池工作状态,维持了母线电压稳定;超级电容器能量密度低,为防止因超级电容器过充、过放而导致系统停止工作,提出了一种基于超级电容荷电状态(SOC)的限值管理策略。使用Matlab/Simulink验证了上述能量管理策略的有效性。
Considering the shortage of the single energy storage system,a kind of energy management strategy of hybrid energy storage system(HESS)was introduced. This method took advantage of the complementary performance of the battery and the supercapacitor,the low pass filtering algorithm was used to distribute system fluctuating power,so that the supercapacitor and the battery absorbed or released the high frequency component and low frequency component of the fluctuating power respectively. It made battery working state optimized and bus voltage stability maintained. Because of the low energy density of supercapacitor,a threshold management solution based on supercapacitor state of charge(SOC)was proposed,so as to prevent system from stoping working due to the supercapacitor charge and discharge limits. Finally,Matlab/Simulink was used to verify the effectiveness of the energy management strategy.
