TL;DR: In this paper, a new operational strategy for a small scale wind farm which is composed of both fixed and variable speed wind turbine generator systems (WTGS) is presented, where series or parallel connected fixed-speed WTGSs are installed with variable-speed wind turbine driven permanent magnet synchronous generators (PMSG).

TL;DR: In this article, a detailed transformation procedure is presented from six-mass drive train model to two-mass model, which can be used in the analysis of transient stability simulation with sufficient accuracy.

TL;DR: In this article, the operation and control strategies of an offshore wind farm interconnected to a high-voltage dc (HVDC) system are presented, where a simple fuzzy logic controller is adopted in the offshore VSC station, which is one of the salient features of this study.

TL;DR: In this article, the authors proposed a control strategy of doubly fed induction generators (DFIGs) with new protection schemes for enhancing fault ride through capability of wind farms composed of DFIGs and induction generators.

TL;DR: In this paper, a fuzzy-logic-controlled superconducting magnetic energy storage (SMES) scheme was proposed for the stabilization of grid-connected wind-generator systems, which is based on a sinusoidal pulsewidth-modulation voltage-source converter and a two-quadrant dc-dc chopper using an insulated gate bipolar transistor.
