Fractional-Order Virtual Synchronous Generator

IEEE Transactions on Power Electronics, 2023
In this letter, a novel control scheme is proposed by combining the fractional-order control and the virtual synchronous generator, whereby more degrees of freedom are involved in the controller design. A well-damped power control without oscillations is achieved. At the same time, a significant improvement in the inertial effect is attained.

An Improved Virtual Inertia Algorithm of Virtual Synchronous Generator [PDF]

Journal of Modern Power Systems and Clean Energy, 2020
Virtual synchronous generator (VSG) simulates the first-order motion equation of a synchronous generator (SG) with the algorithm. VSG can improve the system voltage and frequency support capabilities of a microgrid or a weak grid.

Virtual synchronous generators dynamic performances [PDF]

2014 International Conference on Electrical Sciences and Technologies in Maghreb (CISTEM), 2014
In this paper, dynamic performances of virtual synchronous generator are investigated. The virtual synchronous generator is based on the synchronverter (VSG) concept which is an inverter that mimics a synchronous generator (SG). The real and reactive power delivered by VSGs connected in parallel and operated as generators can be automatically shared ...
