摘要：由于波浪存在随机性和不稳定性，波浪能发电的重要环节是对其间歇发电的管控，而能量存储技术是减轻此影响的一种有效技术。基于蓄电池和超级电容构成的混合储能系统，提出了一种带混合储能的DC/DC变换器，以抑制发电机输出功率的振荡，平滑其电压波动，可直接为直流负载供电，或经逆变器向交流负载供电。并在Matlab/Simulink中进行了建模与仿真，仿真结果验证了所提方案的有效性，对波浪能发电系统的实际应用具有一定的参考价值。

Abstract: As the randomness and instability of surge, the management of their generation intermittency of wave power generation has become one of the main difficulties. In this regard, the energy storage technology is an effective technology for this impact. Based on the hybrid energy storage system composed of storage battery and super capacitor, a DC/DC converter with hybrid energy storage system was proposed to suppress the oscillation of generator. Then, smooth DC power can be directly fed to the DC load or can be controverted to AC to supply to the AC load. The simulation results in Matlab/Simulink prove that the proposed scheme is effective and has a certain reference for the practical application of wave power generation.
