Description
This paper examines the extent to which distinct inter-area electromechanical modes exist in the North American Eastern Interconnect simulations. Electric grids oscillate, and these oscillations have often been described using the linear systems concept of modes. Furthermore, the inter-area behavior of large-scale grids, such as the North American Eastern Interconnect, is sometimes described using just a few dominant inter-area modes. This paper presents a simulation-based approach to determine the extent to which these modes exist. The approach is motivated using a 2000 bus synthetic grid, and then applied to an 87,000 bus model of the North American Eastern Interconnect (EI). The conclusion is while the EI has common patterns of oscillation, when considering a single operating point for the EI consistent distinct modes are not observed. Rather, the calculated apparent modes appear to be disturbance dependent.
