Simplified A-Diakoptics for Accelerating QSTS Simulations

Energies, 2022
The spread of distributed energy resources (DERs) across the distribution power system demands complex planning studies based on quasi-static-time-series (QSTS) simulations, requiring a significant amount of computing time to complete, leading planners ...

Real-time inversions for finite fault slip models and rupture geometry based on high-rate GPS data [PDF]

, 2014
We present an inversion strategy capable of using real-time high-rate GPS data to simultaneously solve for a distributed slip model and fault geometry in real time as a rupture unfolds.

Visualization Methods for Quasi-Static Time-Series (QSTS) Simulations with High PV Penetration

2019 IEEE 46th Photovoltaic Specialists Conference (PVSC), 2019
Distribution system analysis requires yearlong quasi-static time-series (QSTS) simulations to accurately capture the variability introduced by high penetrations of distributed energy resources (DER) such as residential and commercial-scale photovoltaic (PV) installations.

Speckle noise and dynamic range in coronagraphic images [PDF]

, 2007
This paper is concerned with the theoretical properties of high contrast coronagraphic images in the context of exoplanet searches. We derive and analyze the statistical properties of the residual starlight in coronagraphic images, and describe the ...

Accelerating quasi-static time series simulations with foundation models

e+i Elektrotechnik und Informationstechnik
Quasi-static time series (QSTS) simulations have great potential for evaluating the grid's ability to accommodate the large-scale integration of distributed energy resources. However, as grids expand and operate closer to their limits, iterative power flow solvers, central to QSTS simulations, become computationally prohibitive and face increasing ...

Improving the Performance of Integrated Power-Hardware-in-the-Loop and Quasi-Static Time-Series Simulations

IEEE Transactions on Industrial Electronics, 2021
This article introduces a novel multirate cosimulation architecture that overcomes previous challenges integrating faster real-time, microseconds-scale, power-hardware-in-the-loop (PHIL) with larger scale but slower, real-time, seconds-scale, quasi-static time-series (QSTS) simulation.

Electric Vehicles Charging Management for Real-Time Pricing Considering the Preferences of Individual Vehicles

Applied Sciences, 2021
The paper proposes a real-time model for electric vehicles (EVs) controlled load charging. The proposed demand-side management (DSM) of EVs is implemented based on queuing analysis with a nonhomogeneous arrival rate and charging service periods dataset ...

A matched expansion approach to practical self-force calculations [PDF]

, 2005
We discuss a practical method to compute the self-force on a particle moving through a curved spacetime. This method involves two expansions to calculate the self-force, one arising from the particle's immediate past and the other from the more distant ...

Calibration of quasi-static aberrations in exoplanet direct-imaging instruments with a Zernike phase-mask sensor [PDF]

, 2013
Context. Several exoplanet direct imaging instruments will soon be in operation. They use an extreme adaptive optics (XAO) system to correct the atmospheric turbulence and provide a highly-corrected beam to a near-infrared (NIR) coronagraph for starlight

Bearing Capacity of Steel Trusses with Local Damage Considering the Exclusion Time

Buildings, 2023
To ensure the safety of buildings and structures, they must maintain their bearing capacity in case of local damage. The article is devoted to the study of the robustness of damaged steel trusses, as well as the time during which local destruction of the
