A Unified Scheme for Power System Transient Stability Simulation and Transient Stability Assessment

2019 IEEE 8th International Conference on Advanced Power System Automation and Protection (APAP), 2019
Transient stability assessment (TSA) is critical for power system stability analysis and control. Among all efforts to achieve TSA, the transient stability simulation(TSS) plays a fundamental role. In this paper, a unified scheme is proposed for TSS and TSA of numerous power system transient scenarios. The scheme mainly consists of two parts, which are

A parallel transient stability limit search method for online transient stability assessment

2004 International Conference on Power System Technology, 2004. PowerCon 2004., 2005
In this paper, a modified signal energy method called the envelope method will first be proposed to estimate the transient stability limit, and then a parallel envelope method is developed to speed up the limit search for online applications. A new weighting limit estimation formula is used for improving the estimation accuracy and minimizing of the ...

Transient stability of large aluminum stabilized superconductors

IEEE Transactions on Appiled Superconductivity, 1999
Very large current composite superconductors have been considered and adopted to use in SMES coils and fusion applications, such as the Large Helical Device (LHD). These superconductors have large cross-sectional area of high purity aluminum stabilizer to improve their stability and to enhance the overall current density.

Controlling transient stability through line switching

2012 3rd IEEE PES Innovative Smart Grid Technologies Europe (ISGT Europe), 2012
Smart transmission systems have introduced new possibilities of using topology control process for increasing power system dynamic security. Nowadays, in short term analysis, transmission topology is often treated as static and network reconfiguration is performed only for optimizing power flows and market performance.

Transient Stability Sensitivity Analysis

Electric Power Components and Systems, 2004
Based on the time domain simulation, the sensitivity of stability margin with respect to node active and reactive power for the system is derived. They can be used in the location selection of transient stability control devices, stability margin constraint of security based economic dispatch and online stability monitoring.

Transients, Stability and Oscillations

2018
This chapter goes beyond the steady-state behaviour of fast skeletal muscle to look at time-dependent behaviour in all forms associated with full Ca2+-activation. A step perturbation in length, ligand concentration or temperature generates transient behaviour in tension and other observables before reaching a new steady-state, and these transient ...

Determination of the transient stability boundary

IEEE Power Engineering Society General Meeting, 2004., 2004
This work presents an efficient method to determine the transient stability boundary. In terms of the power system variables, the required boundary is nonlinear. The method adopted in This work is to transform the original power system variables into a higher dimensional feature space using a nonlinear transformation.

Assuring transient stability in the smart grid

2012 IEEE PES Innovative Smart Grid Technologies (ISGT), 2012
With unprecedented capabilities for monitoring system operating conditions based on synchronized sub-second measurements and providing quasi-continuous control signals throughout the grid, the smart grid offers the potential to increase all voltage, transient and dynamic (small signal) stability limits to a level above the relevant thermal limits. With

Fast Transient Stability Solutions

IEEE Transactions on Power Apparatus and Systems, 1972
Techniques are described for improving the speed of large transient stability studies without sacrificing accuracy. A fast iterative method for solving the algebraic network equations, including the effect of generator saliency, is explained. A new technique for solving the differential equations with the implicit trapezoidal rule of integration is ...
