基于GPU的大规模配电网电磁暂态并行仿真技术
GPU-based Techniques of Parallel Electromagnetic Transient Simulation for Large-scale Distribution Network
摘要
Abstract
With the integration of distributed generators and other complex devices,analyses of the transient state process for distribution systems and electromagnetic simulation are gradually becoming dependent on detailed modeling and electromagnetic transient (EMT) simulation.As EMT simulation can be appreciably accelerated by fine-grained parallel devices,such as the graphics processing unit (GPU).GPU-based parallel electromagnetic transient simulation techniques for large-scale distribution system are proposed.First,the computational models are formulated by categorizing the overall computations during simulation into three parts,that is,heterogeneous,homogeneous and network solution part.Then,each part of computation is accelerated using fine-grained parallel strategy on the GPU.The heterogeneous part is processed in a layered-directed-acyclicgraph based kernel,the homogeneous part is handled in a fused multiply-add kernel,and the network solution part is done by linear algebraic solvers on the GPU.Finally,large-scale cases are provided for tests.Simulation results indicate that the proposed techniques can significantly accelerate EMT simulation for distribution networks.关键词
