A dual-winding induction machine based inverting system is proposed in this paper. The dual winding induction machine with two electrical interfaces is utilized as an energy conversion hub between the renewable energy source and the grid. It enhances the motor characteristics of the power system while completing the renewable energy integration. In order to make it valuable for application
this paper focuses on its control strategy. This paper sets out the analysis of the operating characteristics of the dual-winding induction machine. The analysis is used to design a set of multi-condition control strategies for different operating conditions. This strategy is intended to meet the control requirements of startup
integration into the grid
grid-connected operation and off-grid operation. The experimental results verify the effectiveness of the proposed control strategy.
