Abstract

With the development of intelligent distribution networks, the type and quantity of equipment in distribution networks show the trend of massive access. The explosive growth of heterogeneous and multi-source data information also puts forward higher requirements for the real-time and reliability of intelligent distribution network protection business. In order to better meet the delay requirements of distribution network protection services, this paper proposes a container-based distribution network protection microservice modeling and computing resource scheduling method. Firstly, the distribution network protection service is decomposed into multiple microservices, and the microservice timing logic model of the distribution network protection service and the container-based microservice architecture of the distribution network protection service are established. Furthermore, the computing resource scheduling model of microservice is established, and the microservice computing resource scheduling result with minimum service delay is obtained by improving the differential evolution algorithm. Finally, simulation examples compare the results of different microservice computing resource scheduling strategies and analyze the impact of CPU computing resources on computing resource scheduling results. The simulation results verify the effectiveness of this method.
