摘要

燃料电池系统（FCS）是公认的有前途的电力系统的电源。然而，现有的FCS模型在大载荷下要么是非凸的，要么是不准确的。本文提出了一种基于机制的FCS可行操作区域（FCSFOA）模型，该模型考虑了燃料电池效率的下降和辅助系统的动态功耗。因此，FCSFOA模型在轻载和重载下都是准确的，与实际数据相比平均误差仅为5.4%。相比之下，电力系统调度中最常用的FCS线性模型的平均误差为24.4%。此外，FCSFOA模型也是凸的，这有利于电力系统的调度。

A Mechanism-Based Convex Model of Fuel Cell Systems Considering the Effect of Auxiliary System

Fuel cell systems (FCS) are recognized as promising electric sources of power systems. However, existing FCS models are either nonconvex or inaccurate when the FCS is under heavy load. This letter proposes a mechanism-based FCS feasible operational area (FCSFOA) model, taking into account the decline in fuel cell efficiency and the dynamic power consumption of the auxiliary system. Therefore, the FCSFOA model is accurate both under light load and heavy load, and the average error is only 5.4% compared with the actual data. In contrast, the FCS linear model, the most commonly used in the dispatch of power systems, has an average error of 24.4% . Besides, the FCSFOA model is also convex, which is favorable for the dispatch of power systems.
