Description
To provide higher efficiency, transmission systems should be operated closer to the stability limits. At the same time reliable and uninterruptable power supply should be ensured. To meet these requirements there is a need of new real-time stability monitoring methods. Furthermore effective methods for the instability prevention are required.
This project is aimed at the development of the early prevention method which should help to maintain system stability in real-time utilizing as input data wide area measurements, provided by Phasor Measurement Units (PMU). Early Prevention method is focusing on the fast identification of the most efficient countermeasure allowing avoiding emerging aperiodic small signal angular instability. Specifically, manipulations applied to the load nodes in the grid are considered as a possible countermeasure.
Developed method will help control room personnel to lead power system safely under stressed operational conditions
