| description | For interconnected system, this paper proposes a control strategy of virtual oscillators with adjustable tie line power. A distributed intra-region control layer is designed based on the dispatchable virtual oscillator-controlled converters. It achieves the distribution of power and maintains frequency stability in different regions. The dispatchable virtual oscillator control improves the transient stability of the system, and the distributed structure enhances the system communication reliability. Further, a centralized inter-region control layer is designed based on the existing scheduling system. It enables power regulation of tie lines and maintains the frequency stability of the whole system. The proposed control strategy is simulated in a high percentage of new energy interconnected system for both sudden load changes and tie line power regulation. The results verify the effectiveness of the method for tie line power regulation and frequency recovery in the interconnected system. |
