With the maturity and widely use of the scalable cluster parallel system, which has a high performance and price ratio, the Transient Stability parallel computing and distributed real time simulation on large scale Power System become possible. This paper firstly outlines the computing model and basic algorithms, and analyzes the main difficulties in algorithms. Then, starting from the basic principles and practical effects of the algorithms, we summarize the research progress of spatial parallel, waveform relaxation and spatial-time parallel Power System Transient Stability algorithms. At last, we compare the advantages and limitations of several parallel algorithms, and point out that the coarse granularity domain decompose Transient Stability parallel algorithm on cluster system is the most promising one.
