ISO New England Experience in Locating the Source of Oscillations Online

The article describes the experience of a successful online implementation of the Dissipating Energy Flow method for locating the source of oscillations in the Oscillation Source Locating (OSL) application. The OSL is a key component of the online oscillation management at ISO New England and in operation since September 2017. The article includes analysis of 1000+ actual oscillatory events processed by the OSL demonstrating the efficiency of the process in locating the source of oscillations.
