Abstract

Low frequency oscillations in the power grid can be classified into three types associated with power system events, non-obvious disturbances, and normal power system operations. A statistical analysis is introduced for the three types of oscillations in the Eastern Interconnection (EI) between 2009 and 2010 supported by the North American power Frequency Monitoring Network (FNET). Six “Type III” oscillation cases in the EI are investigated and some empirical conclusions are compared with “Type I” oscillations.
