Improvement of frequency stability by using battery to compensate rate shortage of LFC reserve
AbstractBy 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.
