There are close oscillation modes exist in large-scale power systems. However, whether the low frequency oscillation (LFO) identification algorithms can distinguish the close frequencies or not is a problem needs to be solved urgently. This paper studies the frequency distinguish ability of Prony, Esprit and Matrix Pencil (MP) three typical identification algorithms based on measurements. Firstly,...
Low frequency oscillation (LFO) is harmful to power system security and stability. The traditional solutions for LFO are the power system stabilizer (PSS) with local or global signal implemented on the excitations. This paper explores the global governor-side damping controllers for LFO, i.e., controller with input from the wide area measurement system (WAMS). Design strategy of global governor-side...
