A Docker-Based Short Circuit Parallel Calculation Strategy in Cloud Platform

This paper proposed a short-circuit calculation parallelization strategy for power system analysis based on Docker technology to improve the efficiency and speed of calculation in cloud platform. This strategy mainly combines the advantage of the lightweight virtual application characteristics of Docker technology and parallel computing strategy to realize high efficiency short circuit calculation. The node matrix parallel decomposition algorithm is used for short-circuit parallel calculation. The Docker container is used to calculate every step of short-circuit parallel calculation and could dynamically be created and released according to the node size. Cloud platform simulation of short-circuit computing of different node sizes is carried out through Cloudsim. In the simulation, the computing time of serial algorithm, virtual machine parallel algorithm and container parallel algorithm was compared. The simulation results shows that the strategy can increasingly improve the efficiency and speed of short-circuit parallel calculation in cloud platform.
