摘要

近年来，基于固体氧化物燃料电池(SOFC)的直流微电网由于其环境友好、能量转换效率高的优点，在世界范围内被考虑用于供电。然而，提高系统效率和保持电力稳定的控制方案都是研究的重点。为此，本文提出了一种基于sofc的直流微电网稳定高效供电的新型控制方案。首先，采用最优工作点(OOPs)来实现系统效率的最大化。此外，在DC/DC升压变换器中采用平均电流控制方式来实现稳定的电力。仿真结果证明了所提控制方案的优越性和有效性，SOFC系统效率可以达到45%以上，直流输出可以很好地调节到设定值并保持稳定。

A Novel Control Scheme of Stable Electricity and High Efficiency Supply in SOFC-based DC Micro-grid

In recent years, the solid oxide fuel cell (SOFC)-based direct current (DC) micro-grid is considered for the power supply worldwide, due to the advantages of the environmentally friendly and high energy conversion efficiency. However, the control scheme for improving the system efficiency and keeping the stable electricity is both the research priority. Thus, a novel control scheme of the stable electricity and high efficiency supply in the SOFC-based DC micro-grid is proposed in this paper. First, the optimal operating points (OOPs) is employed to maximize the system efficiency. Moreover, the average current control mode is adopted in the DC/DC boost converter for the stable electricity. The simulation results are shown to prove the superiority and effectiveness of the proposed control scheme, the SOFC system efficiency can achieve greater than 45%, and the DC electrical outputs can be well regulated to the set value and remain stable.
