Transient synchronization stability mechanism of PMSG with additional inertia control
IET Renewable Power Generation, 2023 Synchronous stability is crucial for the safety and operation of AC power systems. However, most of the current researches focused on the stability of grid‐connected converters, and that of renewable equipment still lacked. In this article, the impact of

Transient Damping Method for Improving the Synchronization Stability of Virtual Synchronous Generators [PDF]
IEEE Transactions on Power Electronics, 2021 The virtual synchronous generator (VSG) was proposed to emulate a synchronous machine's dynamics when integrating power electronic converter-based distributed energy resources to the power grid. However, the VSG's synchronization stability during grid faults is not fully explored. The underlying mechanism of loss of synchronization (LOS) still needs to

Electronics (Switzerland)Conventional grid-forming control often destabilizes voltage source converters (VSCs) in stiff grids, and transient synchronization instability will occur in the grid fault condition. Therefore, power self-synchronization control (PSSC) is first introduced for enhancing the small-signal stability of grid-forming control in the case of a short circuit ...

The impact of virtual synchronous compensator on the transient synchronous stability of renewable energy. [PDF]
Sci RepAbstract The virtual synchronous compensator (VSCOM) integrates virtual synchronous machine control within a static var generator (SVG), providing active voltage support and improving the adaptability of SVGs to weak grid conditions. However, the interaction between VSCOM, which adopts grid-forming control, and renewable energy grid ...

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

Three Technical Challenges Faced by Power Systems in Transition
Energies, 2022 In the 21st century, the worldwide concern about global warming has forced energy to transform in the direction of low-carbon and non-carbon. The utilization of renewable energy is developing rapidly, which makes the non-synchronous generator sources ...

Synchronization and transient stability in power networks and non-uniform Kuramoto oscillators [PDF]
Proceedings of the 2010 American Control Conference, 2010 Motivated by recent interest for multi-agent systems and smart power grid architectures, we discuss the synchronization problem for the network-reduced model of a power system with non-trivial transfer conductances. Our key insight is to exploit the relationship between the power network model and a first-order model of coupled oscillators.
