Functional assessment of DFIG and PMSG-based wind turbines for grid support applications (S-73G)

Summary The specific objectives of this project are to i) investigate the capability of doubly-fed induction generator (DFIG) and permanent-magnetic synchronous generator (PMSG)-based wind turbine systems to provide reactive power support at low wind speed and/or in cases of voltage drop, ii) develop new reactive power control techniques for wind turbines, iii) assess the suitability of using DFIGs to regulate frequency without energy storage systems, and iv) explore the possibility of DFIG inertia sustaining network voltage and frequency immediately following fault occurrence and before fault detection, in systems with low physical inertia and high wind penetration. Experiments will validate proposed theories.
