Parallel domain decomposition simulation for large-scale power grid
نویسندگان
چکیده
This paper presents a fully parallelized domain decomposition (DD) technique for efficient simulation of large-scale linear circuits such as power grids. Domain decompositions using non-overlapping and overlapping partitions are developed to conquer the numerical difficulties in simulation. Experimental results show that by the proposed parallel DD framework, existing linear circuit simulators can be improved for large-scale power grids. Detailed analysis indicate that DD combining multi-grid is suitable for DC simulation and that DD combining LU decomposition performs best for transient simulations.

Mixed Large-Eddy Simulation Model for Turbulent Flows across Tube Bundles Using Parallel Coupled Multiblock NS Solver
In this study, turbulent flow around a tube bundle in non-orthogonal grid is simulated using the Large Eddy Simulation (LES) technique and parallelization of fully coupled Navier – Stokes (NS) equations. To model the small eddies, the Smagorinsky and a mixed model was used. This model represents the effect of dissipation and the grid-scale and subgrid-scale interactions. The fully coupled NS eq...

متن کاملParallel Computing for Reacting Flows Using Adaptive Grid Refinement
The paper reports on the parallelisation of the computational code for modelling turbulent combustion in large industrial 3D glass melting furnaces. Domain decomposition is used to perform the parallelisation. Performance optimisation is examined, to both speed up the code as well as to improve convergence. Local grid refinement is discussed using several different refinement criteria. The nume...
متن کاملMapping Large-Scale FEM-Graphs to Highly Parallel Computers with Grid-Like Topology by Self-Organization
We consider the problem of mapping large scale FEM graphs for the solution of partial diierential equations to highly parallel distributed memory computers. Typically, these programs show a low-dimensional grid-like communication structure. We argue that conventional domain decomposition methods that are usually employed today are not well suited for future highly parallel computers as they do ...
متن کاملA Paradigm for Parallel Unstructured Grid Generation
In this paper, a sequential 2D unstructured grid generator based on iterative point insertion and local reconnection is coupled with a Delauney tessellation domain decomposition scheme to create a scalable parallel unstructured grid generator. The Message Passing Interface (MPI) is used for distributed communication in the parallel grid generator. This work attempts to provide a generic framewo...
