摘要
针对微电网孤网运行模式下,以提高微电网频率稳定性为目的,设计了一种由质子交换膜燃料电池(PEMFC)、水电解装置和储氢装置组成的循环系统,并进行了频率无差补偿。同时提出考虑蓄电池SOC(Stateofcharge)的改进下垂控制参与系统一次调频,并制定蓄电池组和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,所设计的PEMFC循环系统和采用动态下垂控制的蓄电池调频控制策略能够有效实现微电网的频率稳定。
In order to improve the frequency stability of micro-grid in isolated operation mode, a circulating system consisting of proton exchange membrane fuel cell (PEMFC), water electrolysis device and hydrogen storage device was designed to compensate the frequency difference. Meanwhile, the improved droop control considering battery SOC is proposed to participate in primary frequency regulation of the system, and the control strategy of battery group and PEMFC cycle system to participate in frequency regulation is formulated. The results of calculation and simulation show that the designed PEMFC cycle system and the battery frequency modulation control strategy with dynamic droop control can effectively achieve the frequency stability of the micro-grid.
