Disturbance Rejection Control of Grid-Forming Inverter for Line Impedance Parameter Perturbation in Weak Power Grid

When a grid-forming (GFM) inverter is connected to a low- or medium-voltage weak power grid, the line impedance with resistive and inductive characteristics will cause power coupling.

Research on Dynamic and Steady-State Characteristics of Grid-Following/Grid-Forming Hybrid Control Based on Model Predictive Control

IEEE Open Journal of Power Electronics
With the rapid development of renewable energy, the widespread integration of power electronic devices into power generation systems has led to increased grid impedance and reduced short-circuit ratio (SCR), causing the grid to exhibit characteristics of

Phase Field Failure Modeling: Brittle‐Ductile Dual‐Phase Microstructures under Compressive Loading

Advanced Engineering Materials, EarlyView.
The approach by Amor and the approach by Miehe and Zhang for asymmetric damage behavior in the phase field method for fracture are compared regarding their fitness for microcrack‐based failure modeling. The comparison is performed for the case of a dual‐phase microstructure with a brittle and a ductile constituent.

Grid-Forming Control for Enhanced Microgrid Interconnection

, 2023
16201630This paper demonstrates the potential of an enhanced grid-forming control for grid-forming converters, to optimize the interconnection process of black started microgrids (MG) after a global blackout. A point of common coupling switch (PCC switch)

Experiences of Applying Advanced Grid Authorisation Infrastructures [PDF]

, 2005
The widespread acceptance and uptake of Grid technology can only be achieved if it can be ensured that the security mechanisms needed to support Grid based collaborations are at least as strong as local security mechanisms.

Slip Localization Intensification Mediated by Grain Boundary Sliding in a Polycrystalline Nickel‐Based Superalloy

Advanced Engineering Materials, EarlyView.
The temperature dependence of fatigue behavior in nickel‐based superalloys is investigated through high‐resolution measurements of plastic localization. While increasing temperature reduces localization and enhances fatigue performance in René 88DT, Inconel 718 exhibits a sharp degradation at intermediate temperature due to intensified slip ...

Control of a Grid-Forming Inverter Based on Sliding-Mode and Mixed H-2/H-infinity Control

, 2017
A grid-forming inverter (GFI) is an important component for operation of an islanded microgrid. Its purpose, similar to a conventional slack bus generator, is to build up a reference voltage for other distributed generating units in the microgrid ...
