中文摘要:
      在船舶中压直流MVDC(medium-voltage direction current)电力系统中,混合储能系统HESS(hybrid en-ergy storage system)的能量管理策略,可以极大地影响系统的能量利用效率。模糊逻辑能量管理策略,既可以预测HESS的参考功率,以满足负载功率的需求,又可以实现锂电池组和超级电容器组之间的能量分配。用组合型多通道交错双向电流MMBDC(modular multilevel bidirectional current)连接HESS和母线,既可降低开关电流和电压应力,又可减小电感量。在Matlab/Simulink中,建立了MVDC电力系统、HESS、恒功率负载和脉冲负载模型,仿真结果表明:模糊逻辑控制器可以较为准确地预测负载功率的变化并较好地平衡锂电池组和超级电容器组之间的能量分配,为后续船舶中压直流电力系统的能量管理研究奠定了基础。
英文摘要:
      In the ship medium-voltage direct current(MVDC) power system, the energy management strategy for hybrid energy storage system(HESS) can greatly affect the energy utilization efficiency of the system. The energy management strategy based on fuzzy logic can forecast the reference power of HESS to meet the requirements of load power, as well as realize the energy distribution between lithium battery pack and supercapacitor banks. Modular multilevel bidirectional current(MMBDC) is used to connect HESS and MVDC bus, which can not only reduce the stresses of switching current and voltage but also lower the inductance. In Matlab/Simulink, the models of MVDC power system, HESS, constant power load and pulse load are built. Simulation results show that the fuzzy logic controller can more accurately forecast the changes in load power and satisfactorily balance the energy distribution between lithium battery pack and supercapacitor banks, laying a foundation for the follow-up study of energy management for ship MVDC power system.
