Abstract

The invention discloses a power grid topology analysis high-performance calculation method and device based on GPU acceleration, being characterized by according to layering and partitioning characteristics of a power grid model, and abstract characteristics of power grid calculation requirements, carrying out abstract modeling on various components in a power grid, and saving power grid information in a system memory, so that the consistency of data formats between different devices of a CPU and a GPU is kept while the CPU and the GPU can share use data, and the execution efficiency and stability of parallel network topology analysis are guaranteed. The power grid topology analysis high-performance calculation method and device based on GPU acceleration apply the GPU universal parallel computing technology to the power grid network topology analysis, thus improving the execution efficiency of the power grid network topology analysis, and providing real-time support for online analysisand calculation of a large-scale parallel power grid, so that the real-time state of a power grid structure can be obtained more timely during subsequent computing application.

Description

technical field [0001] The invention relates to a high-performance computing method and device for power grid topology analysis based on GPU acceleration, and belongs to the technical field of high-performance computing applications in electric power systems. Background technique [0002] At present, power grid topology analysis is the analysis of the state of components used in the process of conversion, protection and control during the process of electric energy flow. The purpose of topology analysis is to use the analysis results for power grid analysis and calculation. It is between the underlying information (such as SCADA) and high-level applications (such as state estimation and security scheduling). The underlying information is the basis of topology analysis. High-level applications is the purpose of topology analysis. Power grid topology analysis is an important part of the power grid management system and a key step in realizing the "digital" power grid. Since ...
