Abstract
An innovative index, indicative of the relative localness of electromechanical oscillations in electric power systems, is introduced in this paper. The Lindex is calculated using the normalized participation factors obtained from a small signal analysis of the system. With the help of simple representative examples the efficacy of the index to understand power system dynamic behavior, like coherency identification is established.
► This work proposes an index to measure the relative localness of any electromechanical oscillations. ► Thus the index can identify the strongest inter area mode of any large system. ► The index can capture the dynamic behavior of power system. ► The index can also identify the coherency grouping.
