Abstract:

The current research on distribution network terminals based on micro-service and container architecture overlooks the impact of virtualization delay in micro-service scheduling, restricting its application in scenarios with high real-time requirements such as protection and control services. To address this limitation, a micro-service scheduling framework and strategy is proposed for protection and control terminals in distribution networks based on micro-service and container architecture. Initially, an analysis is conducted on the delay performance requirements of protection and control services in the terminal and the impact of virtualization delay, leading to the formulation of a protection and control micro-service scheduling framework. Subsequently, a protection and control micro-service scheduling model is established, encompassing micro-service, delay, and metrics models. A micro-service scheduling strategy based on queue state transitions is then proposed. Finally, extensive case simulations are conducted, where the effectiveness of the proposed scheduling strategy is validated and further optimization of the scheduling strategy is performed. The results indicate that the scheduling strategy proposed can effectively avoid the impact of virtualization delay, and the adoption of first-come-first-serve (FCFS) algorithm achieves better overall performance.
