中文摘要：

随着燃料电池在电力系统中的装机容量日益增大，包含燃料电池（fuel cell，FC）分布式电源的配电网综合负荷建模成为研究热点，阐述了燃料电池的仿真数学模型，并采用适合燃料电池并网的滞环电流控制策略，构建了基于Matlab／Simulink仿真平台的FC发电系统。通过对FC发电系统的稳态和动态运行特性的仿真分析，提出了FC的2阶动态微分方程的等效描述模型。通过对不同扰动强度下的仿真建模比较分析，对该等效描述模型的有效性、泛化能力和参数的稳定性进行了验证。

英文摘要：

With the increasing of fuel-cell capacity in power system, studying the composite load modeling of distribution network with fuel cell （FC） becomes a research hotspot, this paper describes the mathematical model of fuel cell. Hysteretic current control strategy that is suitable for fuel cell integrating to network was adopted to build a fuel cell power generating system in Matlab/Simulink. The second order dynamic equation of state description equivalent model was presented through analyzing the steady and dynamic operating characteristics of FC. The validity, generalization of this equivalent description model and stability of the parameters were testified by comparison of simulation modeling with different disturbance levels.
