中文摘要:

针对现有微电网孤网运行模式，以提高微电网孤网运行时频率稳定性为目的。构造一种循环系统是由质子交换膜燃料电池（PEMFC)，水电解装置，储氢装置组成，实现无差调频。同时提出蓄电池考虑SOC的改进下垂控制参与一次调频。并制定蓄电池组与PEMFC循环系统具体参与调频的控制策略。通过计算与仿真表明，所构造PEMFC循环系统与采用动态下垂系数的蓄电池的调频控制策略能够快速实现微电网一次调频和二次调频。

英文摘要:

The isolated network operating mode of the existing microgrid, in order to improve the frequency stability of the microgrid. a circulating system is made up of a proton exchange membrane fuel cell (PEMFC), a water electrolysis device and a hydrogen storage device to realize frequency modulation without difference.. At the same time, the improved droop control strategy considering the SOC of battery is involved in the primary frequency regulation. The control strategy of the battery pack and PEMFC cycle system in frequency modulation is also proposed. The calculation and simulation shows that the PEMFC cycle system and the FM control strategy using the dynamic droop coefficient can quickly realize the primary frequency modulation and two frequency modulation of the microgrid.
