Parameter Optimization of Grid‐Forming Converters by Maximizing Domain of Attraction Estimates of Converter‐Integrated Power Systems

IET Generation, Transmission &Distribution, Volume 19, Issue 1, January/December 2025.
Grid‐forming converters (GFMCs) are expected to replace synchronous generators (SGs) in future power systems with high penetration of power electronics. This paper proposes a controller parameter optimization method for GFMCs by maximizing the domain of attraction estimates using sum‐of‐squares programming, significantly improving transient stability ...

Green’s Function Monte Carlo Calculations with Two- and Three-Nucleon Interactions from Chiral Effective Field Theory

EPJ Web of Conferences, 2016
I discuss our recent work on Green’s function Monte Carlo (GFMC) calculations of light nuclei using local nucleon-nucleon interactions derived from chiral effective field theory (EFT) up to next-to-next-to-leading order (N2LO).

Fermi surface and pseudogap in highly doped Sr2IrO4 [PDF]

npj Quantum Materials
The fate of the Fermi surface in bulk electron-doped Sr2IrO4 remains elusive, as does the origin and extension of its pseudogap phase. Here, we use high-resolution angle-resolved photoelectron spectroscopy (ARPES) to investigate the electronic structure ...

Phonon Scattering by Local Off‐Centering in Diamond‐Like Cu2−XAgxIn2Se4 Chalcopyrites: High Carrier Mobility and Ultralow Thermal Conductivity

Small Structures
Diamond‐like Cu2−xAgxIn2Se4 (x = 0–0.3) chalcopyrites were synthesized by arc‐melting and investigated as sustainable, tellurium‐free thermoelectric (TE) materials.

Reversible metal-insulator transition in SrIrO3 ultrathin layers by field effect control of inversion symmetry breaking

Communications Materials, 2023
SrIrO3 is a correlated semimetal with narrow t2g d-bands of strong mixed orbital character resulting from the interplay of the spin-orbit interaction due to heavy iridium atoms and the band folding induced by the lattice structure.

Ferroionic inversion of spin polarization in a spin-memristor

APL Materials, 2021
Magnetoelectric coupling in artificial multiferroic interfaces can be drastically affected by the switching of oxygen vacancies and by the inversion of the ferroelectric polarization.

Evaluation of Equivalent Dynamic Active Distribution Network Models with Individual and Aggregated Consideration of Grid Forming Converters

Energy Technology, Volume 11, Issue 12, December 2023., 2023
System stability analysis of future power systems dominated by renewable energies requires comprehensive network models of transmission and distribution systems. This work evaluates a methodology to derive equivalent dynamic network models that render such stability analysis possible.
