随着大量可再生能源的引入和电力管制的放松，为负荷频率控制（LFC）获取足够的备用电力成为系统运营商的难题。本文首先通过仿真研究证明了斜坡速率不足对频率稳定性的影响。其次，提出了一种补偿速率不足的新型电池利用方法。该方法利用现有LFC单元无法响应的LFC信号分量驱动电池。通过与传统电池控制方法的对比研究，表明所提方法能有效提高LFC在大量可再生能源并网情况下的性能。
By introducing large amount of renewable energy sources and electricity deregulation, procuring sufficient reserve power for Load Frequency Control (LFC) becomes difficult for system operator. In this paper, at first, impact of ramp rate shortage on frequency stability is shown by simulation study. Next, a novel battery utilization method is proposed to compensate the rate shortage. In the method, a battery is driven by the component of LFC signal which cannot be responded by existing LFC units. Through comparison study with conventional battery control method, it is clarified that the proposed method can efficiently improve LFC performance under the large amount of renewable energy sources interconnection.
