Abstract: In response to the problem that traditional regional stability control strategy verification methods are difficult to ensure verification effectiveness, this paper proposes an automatic verification method for regional stability control strategies based on cloud host virtual device architecture. Firstly, the theory of cloud models was introduced, and a two-dimensional cloud model was constructed using a cloud generator to achieve complex transformations between qualitative and quantitative methods. Then, using a virtualization based cloud host resource library network traffic model, a cloud model static reactive power compensator controller was constructed, and an Openstack based cloud platform architecture for regional stability control system was built. Corresponding automatic verification methods for regional stability control system control strategies were proposed. Finally, under the same conditions, a comparative analysis was conducted between the proposed method and the other two methods through simulation experiments. The results indicate that its performance is superior to the other two methods.
