On the Impact of Topology on Power System Transient and Frequency Stability

This paper presents a statistical study on the impact of topology of the transmission system on the transient and frequency stability of power systems. We consider four topologies: random graph; small-world graph; nested small-world graph; and lattice graph. These graphs are utilized to generate hundreds of synthetic networks with given topology and adequately generated static and dynamic data. Then, each network is simulated based on a Monte Carlo method and considering random contingencies and different levels of inertia. The case study allows drawing some remarkable conclusions on the correlation between power system stability and topology.
