Enhanced control and parameter analysis for virtual synchronous generators without PLL
Currently, virtual synchronous generator (VSG) technology is proposed to be a solution to stability controlling of micro-source inverter. However, the deviation from phase locked loop (PLL) influences the reference frequency calculating which is ...

Quantitative Analysis Method of Stability Ability for Renewable Electric Energy Delivery System
In this paper, a novel stability ability quantification method based on the amplitude mapping model (AMM) for the GFL–GFM hybrid system is proposed and introduced. Using this method, a concise and practical expression of stability ability can be calculated and derived and the stability of the system can be quantitatively analysed.

Grid‐forming control of direct‐drive permanent magnet synchronous generator (D‐PMSG) wind turbine is an effective method to improve the frequency stability and provide inertia support for the system. In conventional virtual synchronous generator (VSG)–based grid‐forming control, fixed inertia and droop coefficients can result in poor frequency ...

Average‐Filtering Virtual Oscillator Control for Harmonic Voltage Mitigation
Virtual oscillator control (VOC) is a grid‐forming control strategy for microgrids, where the inverter is regulated to emulate the behavior of a weak nonlinear oscillator. Compared to droop control, VOC offers a faster transient response due to its time‐domain approach.
