RT-HIL hardware prototyping of synchrophasor and active load-based power system oscillation damping controllers

The Icelandic power system is characterized by two areas that oscillate against each other during stressed system operation, and may lead to an islanding of system. Conventional stabilizing methods are being used to their full capacity, thus new options are being explored to prevent system break-ups. There is potential in exploiting large industrial loads to enhance system stability. In this paper a hardware prototype of a synchrophasor-based active load controller for oscillation damping is presented. The performance of the controller is analysed using Real-Time Hardware-in-the-Loop (RT-HIL) approach.
