Parallel Program Design and Development of Large-Scale Grid Topology Analysis

This paper proposes a parallel computing method of topological analysis based on the partition of grid model data, and based on the smart grid dispatch control system it design and develop the parallel topology analysis service using the OpenMP shared memory programming model and C/C++ programming language. According to the layering and zoning features of the smart grid dispatch control system, this method divides the grid mode by area and power station. Package the topology search function and do parallel processing for mode data according to different area and power station, which can realize the parallel network topology analysis. The test result on the actual grid shows that this method has good stability and real-time, and it can meet the system online simulation, analysis and control applications requires for the topology analysis.
