Parallel Scheduling Strategy for Multi Time Scale Plan Security Check Based on Unified Computing Resources

摘要

The security check of dispatching plan can be divided into different application modes, such as pre-day plan security check, daily plan security check and real-time rolling plan security check. At present, different time scale security check separately configure independent parallel computing resources, resulting in large waste of resources, and it is not convenient for system operation and maintenance and unified management. This paper proposes a parallel scheduling strategy for multi time scale plan based on unified computing resources. Firstly, the calculation cycle, calculation content and parallel computing resource requirements of different time scale security check applications are analyzed, and the parallel computing task decomposition method of multi time scale security check application is studied. Considering the computing priority and response time requirements of different security check applications, a parallel computing scheduling method based on the unified management of computing resources is proposed, in which the single security check application uses the average scheduling algorithm, and the multi security check application uses priority rotation scheduling algorithm between the multiple security check applications. Based on the unified parallel computing resources, the application of multi time scale plan security check is verified, which greatly shortens the time of each application, and the response time of each application is satisfactory.
