Inter‐area oscillation statistical analysis of the U.S. Eastern interconnection

Abstract

Although extensive studies have been conducted on inter-area oscillation detection and analysis by using phasor measurement data, few has focused on inter-area oscillation statistics due to the lack of considerably long-term and high-resolution recorded data. This paper presents a preliminary statistical analysis on the inter-area oscillations that occurred in the U.S. Eastern Interconnection (EI) from 2010 to 2015. These oscillation events were captured and recorded by the wide area frequency monitoring network FNET/GridEye. Oscillation occurrence, dominant frequency, damping ratio and oscillation excitation types are investigated to explore the statistical characteristics of the detected inter-area oscillations. The results from this study will provide valuable information for system operators and planners regarding network operation and future grid development.
