Long Wavelength Coherency in Well Connected Electric Power Networks

  title={Long Wavelength Coherency in Well Connected Electric Power Networks},
  author={Julian Fritzsch and Philippe Jacquod},
  journal={IEEE Access},
We investigate coherent oscillations in large scale transmission power grids, where large groups of generators respond in unison to a distant disturbance. Such long wavelength coherent phenomena are known as inter-area oscillations. Their existence in networks of weakly connected areas is well captured by singular perturbation theory. However, they are also observed in strongly connected networks without time-scale separation, where applying singular perturbation theory is not justified. We…

Time-Scale Modeling of Dynamic Networks with Applications to Power Systems
Modeling of two-time-scale systems and dynamic networks and area aggregation, and reduced simulations of nonlinear power system models are presented.
The key player problem in complex oscillator networks and electric power grids: Resistance centralities identify local vulnerabilities
This work investigates synchronizable network-coupled dynamical systems such as high-voltage electric power grids and coupled oscillators on complex networks and shows that, when the coupling matrix is Laplacian, key players are peripheral in the sense of a centrality measure defined from effective resistance distances.
Matrix Perturbation Theory of Inter-Area Oscillations
Interconnecting power systems has a number of advantages such as better electric power quality, increased reliability of power supply, economies of scales through production and reserve pooling and
Diffusion and Consensus in a Weakly Coupled Network of Networks
The analysis shows that the first-order approximation of the diffusion and convergence rates is independent of the topologies of the individual graphs; the rates depend only on the number of nodes in each graph and the topology of the connecting edges.
A Tutorial on Matrix Perturbation Theory (using compact matrix notation)
Analytic perturbation theory for matrices and operators is an immensely useful mathematical technique. Most elementary introductions to this method have their background in the physics literature,
Optimal Placement of Inertia and Primary Control: A Matrix Perturbation Theory Approach
The increasing penetration of new renewable sources of electrical energy reduces the overall mechanical inertia available in power grids. This raises a number of issues regarding grid stability over
Quantum signatures of chaos
The distinction between level clustering and level repulsion is one of the quantum analogues of the classical distinction between globally regular and predominantly chaotic motion (see Figs. 1, 2,
