A back-EMF model reference adaptive system (MRAS)-based sensorless control scheme is proposed for a grid-connected doubly-fed induction generator (DFIG). Based on the stator-side and the rotor-side dynamic models of the DFIG, both the reference model and the adaptive model of the proposed back-EMF-based DFIG are investigated. The adaptation mechanism of the proposed controller and the stability of...
The task of autonomous power sharing in a micro-grid is usually achieved by decentralized droop control on individual interface power converters, which may suffer from the dependence on output line impedances. Inaccurate reactive power sharing will occur under strongly non-uniform line impedances. Due to inherently distributed and heterogeneous nature of the micro-grid, it becomes an ideal platform...
This paper studies consensus-based P-f/Q-V droop control in autonomous micro-grids with wind generators and energy storage systems. The consensus control is achieved by deploying sparse and band-limited communication networks such that neighbouring DICs can communicate each other. Two droop control schemes, including (i) the uniform droop gain ratio scheme and (ii) the non-uniform droop gain ratio...
