Research on Energy Management Strategy of Hybrid Energy Storage Module Under High Power Pulse Load

The high power pulse load in Marine integrated power system has the characteristics of high instantaneous power, short duration and high power change rate. The traditional power supply method has been unable to meet its electricity demand, and the hybrid energy storage module composed of super capacitor and lithium battery has become the main method to solve this problem. In this study, the modeling and analysis of pulse load and hybrid energy storage components are carried out. The method of power filter distribution power and supercapacitor SOC limit management strategy are combined to realize the control of hybrid energy storage components, and the simulation is verified. The results show that the proposed strategy can effectively suppress the influence of pulse power on the bus end and improve the stability and reliability of the system.
