| Abstract: | The wide use of scalable cluster parallel systems, which have a high performance -price ratio, has enabled the power flow parallel computing and distributed real time simulation of large scale power system. This paper outlined the computational models and the basic algorithms of power flow computation, and analyzed the main difficulties in the algorithms. Then, starting from the basic principles and practical effects of the algorithms, it presented the research progress of parallel power flow algorithms based on partitioning, multiple factoring, sparse vectors and inverse matrices. Finally, comparing the advantages and limitations of these parallel algorithms, the coarse granularity domain decomposed power flow parallel algorithm on cluster parallel systems is the most promising method. |
