Sensitivity Analysis and Small-Signal Stability of Grid Following Converters

TecnoLógicas, 2022
This article presents a small-signal study, based on a sensitivity analysis, of a voltage source converter (VSC) operating as a grid-following device. This type of operation is standard for integrating distributed energy resources directly into a primary grid without considering the control over specific variables (e.g., voltage and frequency), thus ...

An Orientation Selective Neural Network and its Application to Cosmic Muon Identification

, 1996
We propose a novel method for identification of a linear pattern of pixels on a two-dimensional grid. Following principles employed by the visual cortex, we employ orientation selective neurons in a neural network which performs this task.

Scattering of particles by deformed non-rotating black holes [PDF]

, 2015
We study the excitation of axial quasi-normal modes of deformed non-rotating black holes by test-particles and we compare the associated gravitational wave signal with that expected in general relativity from a Schwarzschild black hole.

Seamless Integration of Grid-Forming and Grid-Following Capabilities in a Single VSI Within a Unified Hybrid Control Framework Under Islanded Conditions

IEEE Access
To achieve seamless integration of grid-forming (GFM) and grid-following (GFL) capabilities in a single voltage-source inverter (VSI) under islanded conditions, this study introduces a unified hybrid control (UHC) scheme with minimal control parameters ...

Improved LVRT Grid Code under Islanding Condition [PDF]

, 2015
The grid code Low Voltage Ride Through (LVRT) requires Renewable Energy Sources (RESs) to remain connected to the grid following the voltage sags resulting from disturbances. The LVRT pattern is based on voltage sag magnitude and its duration at Point of

Interdependency of Transmission and Distribution Pricing

, 2016
Distribution markets are among the prospect being considered for the future of power systems. They would facilitate integration of distributed energy resources (DERs) and microgrids via a market mechanism and enable them to monetize services they can ...

Calpain small subunit homodimerization is robust and calcium‐independent

FEBS Letters, EarlyView.
Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

Impedance-Based Criterion Design for Grid-Following/Grid-Forming Switching Control of Wind Generation System

Energies
As wind farms connect with power grids via long-distance transmission lines and multiple transformers, the resulting networks exhibit inherently weak and fluctuating grid strength—subject to dynamic variations from external disturbances like generation ...
