IEEE Journal of Emerging and Selected Topics in Power Electronics
The interaction between multiple virtual synchronous generators (VSGs) has a nonnegligible impact on the transient stability of the multiparalleled VSG grid-connected (MPVGC) system and may even cause a large number of VSGs to undergo transient ...

IEEE Transactions on Smart Grid, 2019
In the modern power grid, distributed generators are widely connected to the grid via voltage source converters (VSCs). Analyzing the transient stability of VSCs under large disturbances is useful for maintaining the security of the grid.

Transient Stability Analysis Using Shifted Frequency Analysis (SFA)
2018 Power Systems Computation Conference (PSCC), 2018In traditional power systems, the large mechanical inertia of the synchronous generators maintains the system frequency close to 60 Hz. Traditional transient stability programs solve the electrical network at 60 Hz and also use this frequency to convert between power and torque.

Transient Stability Analysis of Power-Synchronized PLL-Less Grid-Following Inverters
IEEE transactions on energy conversionIn the realm of modern power systems, grid-connected inverters are essential for integrating renewable energy resources. While grid-following inverters (GFLIs) currently dominate the market, grid-forming inverters (GFMIs) are pivotal for technology ...

Master stability analysis in transient spatiotemporal chaos
Physical Review E, 2007The asymptotic stability of spatiotemporal chaos is difficult to determine, since transient spatiotemporal chaos may be extremely long lived. A master stability analysis reveals that the asymptotic state of transient spatiotemporal chaos in the Gray-Scott system and in the Bär-Eiswirth system is characterized by negative transverse Lyapunov exponents ...

Stability Analysis of Electromagnetic Transient Simulations
2018We present an analysis of the stability characteristics of the discretized Maxwell-Ampere equations that result from a finite integration of the potential formulation. We demonstrate that the derivation of the discrete versions of these equations will result into unstable formulations unless, in the conversion from a continuous expression to a discrete

Transient stability analysis employing Equal Area Criterion
2011 1st International Conference on Electrical Energy Systems, 2011The introduction of flexible AC transmission system (FACTS) in a power system improves the stability, reduces the losses, reduces the cost of generation and also improves the loadability of the system. In the proposed work, a traditional technique is used to analysis its stability, Equal Area Criterion (EAC) is used to analysis the stability with and ...

Modelling and Transient Stability Analysis of Microgrid
2019 IEEE 5th International Conference for Convergence in Technology (I2CT), 2019The influence of large-scale grid-connected photovoltaics (PV) on power system transient stability is deliberated in this paper. The capacity of conventional synchronous generator needs to be lowered fairly with increasing level of PV capacity. With decline in capacity of synchronous generators overall system inertia downgrades which undesirably ...

Transient stability analysis and improvement in microgrid
2016 International Conference on Electrical Power and Energy Systems (ICEPES), 2016With the growing demand of electricity, deployment of microgrid is becoming an attractive option to meet the energy demands. However, a grid connected microgrid suffers a crucial stability issues during a fault in utility grid. For stable operation of microgrid during fault in grid, islanding operation is generally adapted.
