Doubly fed induction generator model for transient stability analysis
Pablo Ledesma,Julio Usaola +1 more
TL;DR: In this article, a model of the doubly fed induction generator (DFIG) suitable for transient stability studies has been proposed, where the main assumption is that the current control loops, which are much faster than the electromechanic transients under study, do not have a significant influence on the transient stability of the power system and may be considered instantaneous.
Journal ArticleDOI
Probabilistic load flow with correlated wind power injections
TL;DR: In this paper, the authors proposed an approximation that makes use of the properties of statistical moments and Cornish-Fisher expansion to tackle the new problems of probabilistic load flow.
Journal ArticleDOI
Probabilistic load flow with wind production uncertainty using cumulants and Cornish–Fisher expansion
TL;DR: In this article, the authors proposed a probabilistic load flow model for wind power networks with non-Gaussian probability density functions (PDF) and the Cornish-Fisher expansion.
Journal ArticleDOI
Probabilistic load flow in systems with wind generation
TL;DR: In this article, a method for solving a probabilistic power flow that deals with the uncertainties of (i) wind generation, (ii) load and (iii) generation availability in power systems is proposed.
Journal ArticleDOI
Incidence on power system dynamics of high penetration of fixed speed and doubly fed wind energy systems: study of the Spanish case
TL;DR: In this paper, a preliminary analysis of the impact of high wind power penetration in the planning and operation of the Spanish power system is presented, based on the results of dynamic simulations.
