Parallel simulation for the transient stability of power system

Abstract

Parallel time domain simulation is one of the reliable and potential methods that might realize the real-time online transient stability analysis of power system. In the paper, a new parallel calculation method, based on waveform relaxation method, is proposed for power system transient stability analysis. In the method, the entire transmission network is first divided into several subsystems by the geographical location; for each subsystem, its neighboring systems are represented as equivalent voltage sources at the boundary buses; the tie line flows are considered as the communication waveform among the subsystems; then, time domain simulation for each subsystem is performed in parallel. The test result of the practical system indicates that the new parallel algorithm completely achieves the on-line real-time or even over-real-time calculation speed and could be applied to the on-line transient stability analysis of practical system.

A Review of High-Performance Computing and Parallel Techniques Applied to Power Systems Optimization

“…Real-time Contingency and Transient stability with PMV [236] and other formulations with MPI [237] [238]. Faster than real-time transient stability simulation was achieved combining MPI and multi-threading techniques with network and time-domain decomposition in [239], [214] and [240]. Later algorithms were used [241].…”

The Review of Grid-Connected PV System’s Transient Voltage Stability

“…The simulation research Literature [15], [16] performed simulations in transient voltage stability with waveform relaxation method and software MATLAB respectively, the literature [15] proposed parallel strategy has significantly higher than parallel acceleration and computational efficiency, if further combined with some effective measures to speed up, will make the simulation calculation speed to be further improved, so as to achieve the large-scale system online real-time simulation requirements. Literature [16] concluded with transient voltage stability in researching the problems, must want to consider to load the dynamic characteristic from the simulation research found in other, relaying protection action time, asynchronous motor inertia, parallel reactive power compensation devices are about system transient voltage stability impact.…”

The Optimal Controlled Partitioning Strategy for Power System Based on Master-Slave Problem

“…The method has a rigorous theoretical support. In [5], independent two stages of "search+adjust" strategy are proposed based on graph theory. It reduces the partitioning calculation scale greatly, but the solution is only approximate.…”
