钒酸盐氧化还原液流电池提供了许多优于其他能量存储技术的优点。在风电场运行的背景下，这些电池可以大大增强间歇性可再生能源与电力系统的相互作用，并可以提供频率控制等辅助服务。这使得可再生能源的行为更像传统工厂。在本文中，一个新的电源系统模型的钒氧化还原液流电池的介绍和验证，证明了往返效率建模的重要性。然后，建议使用这种电池作为大型风电场的能量存储，通过IGBT SVC连接。已经清楚地证明，这种实施方式能够实现快速有功功率调节，从而允许风电场和储能提供频率调节服务。还分析了控制能量存储以提供对大频率偏差的功率储备响应的几种方法，包括对这些方案的相关损失的关键评估和分析。
Vanadium redox flow batteries offer many advantages over other energy storage technologies. In the context of wind farm operation, these batteries could greatly enhance the interaction of intermittent renewables with the power system and can provide ancillary services such as frequency control. This allows renewable sources to behave more like conventional plant. In this paper a novel power system model of a Vanadium redox flow battery is introduced and validated, demonstrating the importance of round trip efficiency modelling. It is then proposed to use such batteries as energy storage on a large wind farm, connecting through an IGBT SVC. It has been clearly demonstrated that such an implementation enables fast active power regulation that permits both the wind farm and storage to provide frequency regulation services. Several methods of controlling the energy storage to provide a power reserve response to large frequency deviations are also analysed, including a critical evaluation and analysis of the associated losses from such schemes.
