This video presents a short overview of a real-time stability analysis tool implemented on Control Desk software. The algorithm measures grid impedance online and plots the ratio of grid and inverter impedance in real-time as a Nyquist-contour. The purpose of this video is to demonstrate how impedance-based stability margin can be visualized in real-time. More info can be found in the article presented in COMPEL 2017 conference, entitled "Real-Time Impedance-Based Stability Assessment of Grid Converter Interactions".
