Stabilization of a Fixed Speed IG Based Wind Farm using Variable Speed PMSG

Abstract

To optimize the output power and reduce the frequency fluctuation in conventional fixed speed Induction Generator (IG) based wind farm, various controlling devices are used. But, this paper proposes that Permanent Magnet Synchronous Generator (PMSG) can work both as a power producing device and as a controlling device for IG. In this paper a more practical case has been considered where a wind farm is operated with a set of Synchronous Generators (SG). Thermal, Hydro and Nuclear Governors have been used for SGs. Wind farm has a capacity of 20% of the total SG's capacity. Both two-level and three-level converter-inverter based PMSG have been considered. Comparative results between IG and IG with PMSG are shown. Simulation results prove the effectiveness of the proposed system. Simulations have been carried out by using the laboratory standard power system software package, PSCAD/EMTDC.

Optimizing of Induction Based Wind Energy Conversion System with EDLC and PMSG for Efficient Power Control

“…It suggests combining EDLCs with batteries to improve power ow leveling and voltage stability, particularly in challenging topographical conditions. M. S. Zinat Tasneem et al, [3] study addresses the issue of output uctuations in wind farms caused by varying wind speeds, particularly for xed-speed wind generators like induction generators (IG).…”
