本文描述了一种可用于暂态稳定性研究的SOFC燃料电池动态模型。将该模型应用于使用燃料电池和燃气轮机作为分布式发电机(DG)的分布式电网。利用基于商业电力系统工具箱和MatLab中SIMULINK开发的软件，对不同DG功率输出下系统的暂态稳定性进行了研究。提出了一种将燃料电池接入电网的方法。通过对燃料电池逆变器触发角的控制设计，提高了系统的暂态稳定性。
This paper describes a dynamic model of a SOFC fuel cell, which can be used in transient stability studies. The model is applied to a distributed utility grid that uses a fuel cell and a gas turbine as distributed generators (DGs). Transient stability of the system is investigated for different DGs power outputs using a software developed based on the commercial Power System ToolBox and SIMULINK in MATLAB. A method for interfacing the fuel cell to the grid is presented. Transient stability is enhanced through a control design of the firing angle of the fuel cell inverter.
