Wind energy conversion systems using the doubly-fed induction generator (DFIG) are the most commercialized topology worldwide, because this technology uses converters dimensioned for ±30% of the system rated power, thus reducing the equipment cost. The direct connection of the DFIG stator to the electrical system increases its sensitivity to grid disturbances. In this context, this paper analyzes...
The voltage at the point of common coupling (PCC) in a weak network is very sensitive to load changes. A sudden change in active load will cause both a phase jump and a magnitude fluctuation in the bus voltage (voltage at the PCC), whereas reactive load changes mainly affect the voltage magnitude. With the addition of energy storage to a static synchronous compensator (STATCOM), it is possible to...
This paper proposes and outlines a systematic procedure based on intelligent control methods for the purpose of enhancing the design and associated performance of a medium-scale WECS with permanent magnet synchronous generator (PMSG) connected to a medium voltage (MV) distribution grid. More specifically are achieved rapid, accurate, stable and simultaneous: MPP tracking of the WT with PMSG, dc voltage...
