Automatic Verification Method for Control Strategy of Regional Stability Control System Based on Cloud Host -Virtual Device

A method for automatic verification of control strategies in regional Stability Control Systems(S-CS) based on Cloud Host (C-H) virtual device architecture is proposed to address the issue of traditional methods for verifying control strategies in multi-site comprehensive testing, which are difficult to ensure the effectiveness of verification. Firstly, based on cloud model theory, a two-dimensional cloud model was constructed by combining forward and reverse cloud generators to achieve complex qualitative and quantitative transformations. Then, by planning the network traffic and structure of the C-H resource pool and building the cloud model SVC controller, the overall architecture of the SCS cloud platform is built based on Openstack, and the corresponding automatic verification method of the regional SCS control strategy is proposed. Finally, a comparative analysis was conducted between the proposed method and the other two methods under the same conditions through simulation experiments. The results show that the proposed method can more accurately track the power angle and voltage of the system. The peak error, average error, and time consumption of the power angle response are 5.78%, 3.97%, and 4.21 seconds, respectively, while the voltage response is 2.35%, 7.46%, and 2.35 seconds, respectively. The performance is superior to the other two comparison methods.
