Characterization of Oscillations in Developing Power Systems: The Nigerian Case Study
The proper understanding of the nature and sources of low-frequency oscillations presents a problem for power systems in developing countries because of the inherent continuous network expansion and overloading. In this paper, a thorough study of oscillations in the Nigerian 48-bus power system is presented. The system's dominant modes and sensitive disturbance locations are identified. The results show that severe inter-area phenomena exist due to the low-frequency modes identified at 1 Hz, 1.14 Hz, and 1.37 Hz. These oscillations were discovered to be associated with the generators at Kainji, Afam, and Delta power stations.
