PROJECT TITLE :
Enhanced frequency response strategy for PMSG based wind energy conversion systems using ultra capacitor in remote area power supply systems - 2017
ABSTRACT:
Conventional generators in wind-diesel hybrid remote-space power offer (RAPS) systems are seemingly to be heavily stressed throughout frequency disturbances because of poor frequency response of Power Electronic interfaced wind energy conversion systems (WECSs). Hence, it's imperative for the WECS to produce frequency support throughout frequency excursions. However, existing frequency management methods are slow and can additionally impose severe mechanical/electromagnetic stress on WECSs. During this paper, frequency response methods for the PMSG-based WECS are explored, and an enhanced frequency response strategy is investigated to control the RAPS system frequency jointly with the integrated ultracapacitors. The proposed short-term frequency response strategy utilizes a virtual inertial technique along with the supplementary droop control. Suboptimal power-point-tracking is also implemented at the PMSG to boost the active power reserve. The enhanced frequency response strategy can regulate the RAPS system frequency whereas alleviating high rate-of-amendment-of-power, and so stresses on each the traditional generator and PMSG beneath frequency disturbances. Proposed control strategies are validated by each simulations and experiments.
