A decomposition method for network-constrained unit commitment with AC power flow constraints
TL;DR: In this article, a decomposition method is proposed to solve network-constrained unit commitment (NCUC) with AC power flow constraints, and feedback constraints are generated based on the sensitivity of bus voltages to a change in the unit reactive power generation.
Journal ArticleDOI
Agent based modeling of energy networks
TL;DR: This article addresses the issue of modeling a local multi-carrier energy network by integrating a multiagent algorithm to perform the task, in a concurrent way to the other simulation tasks, and not only for the electric fluid but also for a number of additional energy carriers.

Nonlocal failures in complex supply networks by single link additions
Dirk Witthaut,Marc Timme +1 more
TL;DR: It is demonstrated that and how adding new links may not only promote but also degrade stable operation of a network, and how the resulting overloads may emerge remotely from where such a link is added, thus resulting in nonlocal failures.

Reactive power control of DFIG wind turbines for power oscillation damping under a wide range of operating conditions
TL;DR: In this paper, the effect of replacing existing synchronous generators equipped with power system stabilisers (PSS) by doubly fed induction generator (DFIG) based wind farms on the damping of power system oscillations in a multi-machine power system was analyzed.
