Control strategy of AC DC hybrid generating system based on dual stator-winding induction generator for micro-grid application

摘要

For hybrid AC& DC micro-grid, this paper proposes a new generating system based on dual stator-winding induction generator (DWIG). This generating system can realize bidirectional energy flow, reduce the number of converters and simplify the structure of micro-grid. To meet the requirement of supplying AC and DC power simultaneously, this paper proposes the control winding voltage oriented (CWVO) control strategy on the basis of instantaneous reactive power theory. Through the analysis of simulation results, the feasibility and accuracy of this generating system and its control strategy is validated. This paper lays the foundation for future research for hybrid AC& DC micro-grid.
