Abstract

The invention relates to a load reduction parallel computing method, which reads branch node disconnection data, divides the branch node disconnection data into multiple partitions of a data parallel computing platform, and obtains a load reduction algorithm of Matlab and Java mixed programming package; call the load reduction algorithm package in each partition to calculate the branch node disconnection data in the current partition, and obtain the load reduction amount of the branch node. By calling the load reduction algorithm package of Matlab and Java mixed programming to calculate the branch node disconnection data in parallel, and obtain the load reduction amount of the branch node, it greatly reduces the difficulty and complexity of parallel development of the load reduction algorithm. When a new load reduction algorithm is added The algorithm can be parallelized by performing mixed programming of Matlab and Java on the new algorithm to obtain the load reduction algorithm package, which has good universality.

Description

technical field [0001] The invention relates to the technical field of power grids, in particular to a parallel computing method for load reduction. Background technique [0002] With the continuous growth of power demand and the continuous expansion of grid interconnection scale, the operation and control of power system needs to process a large amount of data, and has high requirements for real-time performance. The traditional serial method of power system load reduction calculation cannot meet the simulation requirements of large-scale power network online analysis and real-time control in terms of processable scale and solution speed. Therefore, a feasible parallel computing solution that supports the rapid solution of complex problems is proposed. [0003] At present, the parallel computing of power analysis is generally based on MPI (Message-Passing-Interface, message passing interface) to realize parallel computing. However, there are many algorithms used in load re...
