PROBLEM TO BE SOLVED: To provide an instantaneous value analysis system of an electric power system using a sparse tableau approach that achieves rapid analysis of instantaneous values.SOLUTION: According to the present invention, there is provided an instantaneous value analysis system of an electric power system, performing the steps of formulation (I), solution (II), and inner state update (III). The update step (III) includes mode selecting means 1 selecting one of a sequential processing mode 2 for sequentially processing the inner state and a concurrent processing mode 3 for concurrently processing threads 3A to 3D by dividing the threads. In the division of the threads 3A to 3D in the concurrent processing mode 3, the threads 3A to 3D are optimized so that the processing capacities of the threads are equalized, comparison is made between a maximum concurrent processing time, which is the sum of a maximum processing time for the threads after the optimization and an overhead associated with the parallelization, and a sequential processing time required for the sequential processing, and the inner state update is performed in the concurrent processing mode only when the maximum concurrent processing time is shorter. |
