Impact of Digital Control Delay on Stability of Grid-Following Converters

2022 IEEE 13th International Symposium on Power Electronics for Distributed Generation Systems (PEDG), 2022
In a digital controlled system, the delay is inevitable. It will change the phase-frequency characteristics of the system, which will affect the stability. This paper analyzes the configuration of the grid-following converter and builds its small-signal model in detail.

Power-Based Droop Control in DC Microgrids Enabling Seamless Disconnection From Upstream Grids [PDF]

, 1997
This paper proposes a local power-based droop controller for distributed energy resource converters in dc microgrids that are connected to upstream grids by grid-interface converters.

Grid–Following DVI–Based Converter Operating in Weak Grids for Enhancing Frequency Stability [PDF]

IEEE Transactions on Power Delivery, 2022
Inertia requirement is the paramount challenge in future power systems with a significant share of renewable energy generators. A promising solution to this issue is applying Distributed Virtual Inertia (DVI) concept, i.e. releasing energy preserved in the dc-link capacitors of employed power converters in the grid following a frequency disturbance ...

Grid-Synchronization Stability of Converter-Based Resources—An Overview

IEEE Open Journal of Industry Applications, 2020
This paper presents an overview of the synchronization stability of converter-based resources under a wide range of grid conditions. The general grid-synchronization principles for grid-following and grid-forming modes are reviewed first. Then, the small-

A Comparative Study of Grid-Following and Grid-Forming Control Schemes in Power Electronic-Based Power Systems

Power Electronics and Drives, 2023
Along with de-carbonisation, the penetration of power electronic converters has increased, and the power system has become a power electronic-based power system. In such a situation, the stability of the power system faces great challenges.

Modeling and Control of Grid Forming Converters: A Systematic Review

IEEE Access
In electrical power systems where the proportion of synchronous generators (SG) is gradually decreasing, grid-forming (GFM) converters need to be installed and controlled to meet all the system requirements that SGs have provided to date.
