Revised transient stability index for smart grids

Abstract

In this paper the physical concept, calculation method and application possibilities of a novel stability index are briefly summarized. The details of the calculation method resulting in a better characterization of the dynamic security of the power system are published. The aim of our work is to develop a stability index for filtering stability calculation cases made for network development planning and to provide a possibility of real-time stability monitoring for power system dispatchers. Simulation results of model network are described, conclusions are drawn and evaluated.
