PARALLEL COMPUTING METHOD AND COMPUTING PLATFORM FOR SECURITY AND STABILITY ANALYSIS OF LARGE POWER GRID

摘要

A parallel computing method and computing platform for the security and stability analysis of the large power grid are provided, which can solve the problem that the efficiency of the computational analysis of the prior art is lower. The parallel computing method includes: dividing the computing task into at least two task sets, and allocating the at least two task sets and the fixed data corresponding to each task set to each computational node; sending the operating data of the power grid to each computational node; performing the parallel computing by each computational node based on the operating data of the power grid and the fixed data. The computing platform includes: the management node and the computational node. This invention simplifies the complexity of the task schedule and improves the stability of the system, by the means of the combination of task parallel computing and sub network parallel computing, based on the data broadcast, the task pre-allocation, the time sequence control and by using massively parallel algorithms to compute the security and stability analysis of the large power grid.
