Real Time Monitoring of Power Grid Stability

This technology provides a novel method to estimate power grid stability by measuring in real time, with a single time-point, instabilities and drift at a power grid node, such as a power substation. The algorithm allows an estimation of the Thevenin equivalent of the grid as seen from local substation busses in a power station. Voltage stability, angle stability, system islanding and other predictors of system behavior can be estimated using this technique. The method can be implemented with current transformers and voltage transformers typically present at power substations or newer phase measuring units. Advantages:

Rapid measurement of power grid state

Single time point measurement

Allows response to fast voltage or phase instabilities
