Enabling Aggregation of Heterogenous Grid-Forming Inverters via Enclaved Homogenization

IEEE Access, 2022
This paper proposes a control scheme to force homogeneity for heterogenous network of the grid-forming (GFM) inverters in power electronics dominated grid (PEDG) to enable their aggregation and coherent dynamic interaction.

Swing equation modelling of GFL inverter and comparison of its damping and inertia with GFM inverter [PDF]

, 2022
The increasing integration of inverter-based renewable generation into the network as Grid-Following inverters (GFL), combined with the reduction in traditional Synchronous Generation (SG) leads to a reduction in inertia and to instabilities.

Current limiting control method with adaptive virtual impedance for grid-forming STATCOM

Energy Reports, 2023
Current limiting is an important issue in the static synchronous compensator (STATCOM) with grid-forming (GFM) control. However, the conventional methods are difficult to deal with the application scenarios of different grid faults.

A Simplified SISO Small-Signal Model for Analyzing Instability Mechanism of Grid-Forming Inverter under Stronger Grid [PDF]

, 2021
Different from grid-following inverters, grid-forming (GFM) inverters tend to be unstable under stronger grid conditions. However, the instability mechanism is still absent in existing research.

Voltage-Based Current Limitation Strategy to Preserve Grid-Forming Properties Under Severe Grid Disturbances

IEEE Open Journal of Power Electronics, 2023
Grid-forming (GFM) converters are a promising solution to enable large scale integration of renewable energy sources into the power system. However, due to the intrinsic voltage-source behaviour of GFM converters, current limitation during large grid ...

PHANTOM: a Monte Carlo event generator for six parton final states at high energy colliders [PDF]

, 2009
PHANTOM is a tree level Monte Carlo for six parton final states at proton--proton, proton--antiproton and electron--positron collider at O(alpha_ew^6) and O(alpha_ew^4*alpha_s^2) including possible interferences between the two sets of diagrams.

Evaluation of Frequency Support using Synthetic Inertia for GFM Inverters [PDF]

, 2021
Grid-following(GFL) PV inverter cannot control the voltage and frequency of the grid. With the high penetration of renewable resources into the grid, the inertia of the system was reduced drastically. This leads to frequency stability problems especially
