氧化还原液流电池(RFB)是一种很有前途的电网储能系统。RFB具有响应速度快、容量大、可伸缩性强等优点。由于这些优点，RFB可以在混合时间尺度上运行。事实证明，RFB可以用于负载均衡、补偿凹陷和平滑可再生能源的输出。对于这些应用来说，对RFB的暂态行为进行分析是一个关键问题。RFB受电气、化学和流体动力学的制约。这种混合结构给分析带来了困难。为了分析RFB的暂态行为，精确的模型是必要的。在本文中，我们主要研究了电解液中离子浓度的变化，并用一个主要基于化学动力学的模型进行了模拟。仿真结果给出了RFB在负载变化时的暂态行为。发现了包括振荡在内的三种典型的暂态行为。结果表明，由于系统的慢动态和快动态，系统的复杂的暂态行为是由对负载的快速响应引起的。
A Redox Flow Battery (RFB) is one of the promising energy storage systems in power grid. An RFB has many advantages such as a quick response, a large capacity, and a scalability. Due to these advantages, an RFB can operate in mixed time scale. Actually, it has been demonstrated that an RFB can be used for load leveling, compensating sag, and smoothing the output of the renewable sources. An analysis on transient behaviors of an RFB is a key issue for these applications. An RFB is governed by electrical, chemical, and fluid dynamics. The hybrid structure makes the analysis difficult. To analyze transient behaviors of an RFB, the exact model is necessary. In this paper, we focus on a change in a concentration of ions in the electrolyte, and simulate the change with a model which is mainly based on chemical kinetics. The simulation results introduces transient behaviors of an RFB in a response to a load variation. There are found three kinds of typical transient behaviors including oscillations. As results, it is clarified that the complex transient behaviors, due to slow and fast dynamics in the system, arise by the quick response to load.
