摘要：

Existing research on transient stability issues of virtual synchronous generators only focuses on single-machine systems. Because a single-machine system does not need to consider the coupling effects between units in the multi-machine system, and the multi-machine system has a high order and complexity. As a result, the existing transient stability analysis methods of virtual synchronous generators are not suitable for multi-virtual synchronous generators systems. In this paper, a transient stability analysis method for the multi-virtual synchronous generators system is proposed, and an active external loop control strategy is proposed to ensure the transient stability of a multi-virtual synchronous generators system. Finally, the correctness and effectiveness of the theoretical analysis are verified by building a PSCAD simulation model.
