Stability analysis of DFIG controlled by hybrid synchronization mode and its improved control strategy under weak grid

open access: yesIET Renewable Power Generation, 2023
In order to improve the stability of doubly‐fed induction generator (DFIG)‐based wind turbines under weak grid, previous works have proposed the power synchronization control strategy in the rotor side converter (RSC).

Pre-synchronization Control Method for Virtual Synchronous Generator Based on Power Matching and Self-adaptive Inertia [PDF]

open access: yesZhengzhou Daxue xuebao. Gongxue ban, 2023
It was necessary for the virtual synchronous generator (VSG) to be synchronized with the grid when it switched from off grid mode to grid connected mode.

Open Loop Synchronization Techniques Benchmarking for Distributed Energy Sources Connection

open access: yesIEEE Access, 2022
Synchronization is a crucial process in the operation of grid-connected distributed energy sources. Synchronization techniques are classified in closed-loop (CLS) and open-loop synchronization (OLS) techniques.

Grid protocols based on synchronous communication

open access: yesScience of Computer Programming, 1997
AbstractWe provide a short notation for processes with parallel inputs and outputs. With this specification format synchronous networks or grid protocols can be specified in a straightforward way. For a certain class of connected networks we prove a correctness theorem that characterizes I/O behavior.

A voltage-sensorless controller for grid converters

open access: yes, 2021
Grid converters need information about the point-of-common-coupling voltage for their control. The voltage is typically measured for current and ac-bus voltage control, and for synchronization. In order to increase reliability by decreasing dependence on

A Proposal for a Multi-Agent based Synchronization Method for Distributed Generators in Micro-Grid Systems [PDF]

open access: yesEAI Endorsed Transactions on Industrial Networks and Intelligent Systems, 2016
A synchronization technique based on the Multi-Agent Systems approach, is proposed for a group of Distributed Generators belonging to a Micro-Grid. The Average Time Synchronization consensus algorithm is used.

Setting Configuration and Adjustment Method of Synchronous Condenser System Under Idling Conditions

open access: yesZhongguo dianli, 2023
When connecting the idling condenser to the grid, it is difficult to configure the setting value of the synchronization system to balance the requirements of grid connection success rate and current shock together. In this paper the idling characteristic

Adaptive Grid-Synchronization Control with Dual Features of Grid-Forming and Grid-Following for VSCs

open access: yes, 2023
An adaptive grid-synchronization control for voltage source converters (VSCs) is proposed. The proposed control has both grid-forming (GFM) and grid-following (GFL) ingredients, which makes it exhibit GFM-GFL dual features and the advantages of both.

Modeling of Converter Synchronization Stability Under Grid Faults:The General Case [PDF]

open access: yes, 2022
The synchronization dynamics of grid-connected power converters are known to have a tremendous impact on transient stability and fault ride-through performance under grid faults. Up till now, the modeling of converter synchronization stability, which has

Two-dimensional patterns with distinct differences; constructions, bounds, and maximal anticodes [PDF]

open access: yes, 2010
A two-dimensional (2-D) grid with dots is called a configuration with distinct differences if any two lines which connect two dots are distinct either in their length or in their slope.
