  • A preconditioner for transient stability time domain simulation 

    Authors:Soykan, Gürkan; Flueck, Alexander J.; Daǧ, Hasan
    Publisher and Date:(2011)
    Transient Stability analysis which is one of the most important tasks of power system dynamic security analysis determines the dynamic behaviour of the power system after a large disturbance. Differential and algebraic equations (DAEs) model the nonlinear dynamic power system. The conventional time domain solution process uses a Newton method to simultaneously solve the differential equations discretized via an implicit integration method alongside the non-linear algebraic network equations. Direct ...

  • Distributed Memory Parallel Transient Stability Analysis on a PC Cluster with Ethernet 

    On-line transient stability analysis is a necessity for real-time power system control and security. Parallel processing is a natural technology for achieving real-time solution performance. This paper presents a parallel-in-space algorithm based on a multi-level partitioning scheme in a distributed memory cluster environment. The main aim of the research is to decrease the wallclock time of transient stability analysis of large scale power systems by leveraging open source software and commodity ...

  • Parallel-in-space implementation of transient stability analysis on a Linux cluster with infiniband 

    Authors:Soykan, Gürkan; Flueck, Alexander J.; Daǧ, Hasan
    Publisher and Date:(IEEE, 2012)
    On-line transient stability analysis is an inevitable way to provide real time power system security and control. Parallel computing is one of the most viable ways to perform on-line transient stability analysis. This paper presents the performance results of a parallel-in-space algorithm based on a multilevel partitioning scheme on an Infiniband cluster system. The algorithm decreases the transient stability simulation time using METIS for partitioning in conjunction with the linearized update ...
