Natural synchronization in power-grids with anti-correlated units

摘要: Abstract Synchronization between spatially distributed nodes of a power-grid is crucial requirement for its proper operation. Using Kuramoto-like network as realistic physical model the distribution electrical power in power-grid, we obtain coupling strengths and topological characteristics that favor synchronous state those technological networks. Power-grids are highly heterogeneous. They composed different classes each node behaves differently. We show this work if extensive connected, strength leads to synchronization depends mainly on eigenvalues Laplacian matrix, it happens homogeneous networks equal nodes. On other hand, sparsely also strongly related correlation coefficient network, which means high number connections similar (two plants or two consumer centers) disfavor synchronizability power-grid. apply our results Brazilian system.
