Harmonic analysis in a power system with wind generation
TL;DR: In this paper, a case study for a 10MW wind farm, intended to be connected to a network with extended high-voltage submarine cable lines, is presented, where the harmonic impedance of the system is calculated for a variety of configurations and operating conditions, and its main characteristics are discussed.

Continuum modeling of electromechanical dynamics in large-scale power systems
TL;DR: The continuum model presented here therefore relaxes the isotropy and homogeneity constraints assumed in the prior work and is able to model the real power systems that tend to be highly irregular in terms of their geographical topology and the power injections, loads, and shunt elements at the bus locations.

Convex Optimization of Power Systems
TL;DR: In this paper, a rigorous exposition introduces essential techniques for formulating linear, second-order cone, and semidefinite programming approximations to the canonical optimal power flow problem, which lies at the heart of many different power system optimizations.

Stochastic Model for Power Grid Dynamics
TL;DR: A stochastic model that describes the quasi-static dynamics of an electric transmission network under perturbations introduced by random load fluctuations, random removing of system components from service, random repair times for the failed components, and random response times to implement optimal system corrections for removing line overloads in a damaged or stressed transmission network is introduced.
