Recent advances in synchronization techniques for grid-tied PV system: A review

open access: yesEnergy Reports, 2021
The contribution of solar photovoltaic (PV) in the electrical power sector is increasing expeditiously. Recent interest in the integration of solar PV into the grid raises concerns about the synchronization technique. Continuous research has successfully

A PLL-Less Fourier Analysis Based Self-Synchronizer for Synchronverter having Uninterrupted Power Supply Capability

open access: yese-Prime: Advances in Electrical Engineering, Electronics and Energy, 2023
With the passage of time, more and more power electronic converters are being integrated in power system. This growing pattern of inertia-less inverters challenges the system frequency and voltage.

Small-signal synchronization stability of grid-forming converter influenced by multi time-scale control interaction

open access: yesEnergy Reports, 2023
The grid-forming (GFM) converters that simulate the dynamics of synchronous generators (SGs) and actively participate in grid voltage and frequency regulation are increasingly employed as grid interfaces for renewable energy generation.

Synchronization of Inverters in Grid Forming Mode

open access: yesIEEE Access, 2022
This article compares two strategies for seamless (re)connection of grid-forming inverters to a microgrid powered by droop-controlled inverters. While an incoming inverter must be synced to the microgrid, seamless syncing and power-sharing are technical challenges for grid-forming inverters.

A study of the transient synchronization stability of PLL-GFC-based MMC-HVDC systems

open access: yesZhejiang dianli, 2023
Phase-locked loop-based grid-forming converters (PLL-GFCs) can regulate frequency and voltage. However, the transient synchronization stability after their connection to the high-voltage AC power grid is unclear.

Control of synchronization in two-layer power grids [PDF]

open access: yesPhysical Review E, 2020
In this work we suggest to model the dynamics of power grids in terms of a two-layer network, and use the Italian high voltage power grid as a proof-of-principle example. The first layer in our model represents the power grid consisting of generators and consumers, while the second layer represents a dynamic communication network that serves as a ...

Synchronization of cyclic power grids: Equilibria and stability of the synchronous state [PDF]

open access: yesChaos: An Interdisciplinary Journal of Nonlinear Science, 2017
Synchronization is essential for the proper functioning of power grids; we investigate the synchronous states and their stability for cyclic power grids. We calculate the number of stable equilibria and investigate both the linear and nonlinear stabilities of the synchronous state.

Remote Micro-Grid Synchronization Without Measurements at the Point of Common Coupling

open access: yesIEEE Access, 2020
This article presents a new strategy of active synchronization of an island micro-grid and the utility grid (UG) without measurements at the point of common coupling (PCC). This strategy is based on the assistance of Ethernet communication, GPS pulse-per-

How modular structure determines operational resilience of power grids

open access: yesNew Journal of Physics, 2021
The synchronization stability has been analyzed as one of the important dynamical characteristics of power grids. In this study, we bring the operational perspective to the synchronization stability analysis by counting not only full but also partial ...
