There are significant concerns regarding the stability of increased wind power generation in weak grids. This paper investigates and improves Wind Turbine Squirrel Cage Induction Generators (WT-SCIGs) with series compensation interconnections to grid. Detailed time-domain state-space modeling have revealed new bifurcations oscillatory modes for a WT-SCIG connected radially grid through compensa...

<p><span lang="EN-US">A stable operation of wind turbines connected to the grid is an essential requirement ensure reliability and stability power system. To achieve such operational objective, installing static synchronous compensator (STATCOM) as a main compensation device guarantees voltage enhancement farm distribution network at different operating scenarios. STATCOM either sup...

This paper proposes a high-order sliding mode control (HO-SMC) with the super-twisting (ST) algorithm for maximum power point tracking (MPPT) and grid-connected wind energy conversion system (WECS), based on squirrel-cage induction generator (SCIG). The main features of this strategy are attenuation chattering phenomenon inherent in first-order its robustness against external internal disturban...

a detailed model of wind power station, including double fed induction generator, dfig is presented in this paper. two control mechanisms are included in the model. the inner control system uses stator flux oriented control for the rotor side converter and grid voltage vector control for the grid side converter. the outer control system is used for wind turbine pitch angle. pscad/emtdc is used ...

Injection of wind power into an electric grid affects the power quality and reactive power issues at the connected electric network. Power quality problems such as voltage sag are some major concern. In this paper these issues are analyzed. Wind turbine connected to squirrel cage induction generator is modeled using PSCAD simulation software to analyze the said issues where STATCOM is introduce...

The integration of high proportion renewable energy not only brings many benefits, but also increases the difficulty power system stability analysis. One reasons for this problem is unclear internal characteristics new equipment. Therefore, there an urgent need a more detailed analysis Taking double-fed induction generator (DFIG), which has complex operation and widely used, as example, functio...
