Double Parallel Optimization Method of Short-term Joint Dispatch of Giant-scale Hydropower Station Groups
Tang Haihu · Water Resources and Power · 2013
For the high accuracy and timeliness requirements of short-term joint dispatch of giant-scale hydropower station groups,double parallel optimization method based on topological structure of hydropower station groups and optimization trajectory of algorithm is designed with multi-core PC clusters.Multi-process and multi-thread synchronous parallel computing are implemented with mixed fine-grained model of MPI and OpenMP.Finally,this article analyzes the calculation performance of algorithm with different numbers of hydropower station and process.The instance results show that the calculation time is reduced greatly on the premise of ensuring optimization accuracy,and the computing efficiency is improved significantly.
