Abstract

Virtual synchronous generator (VSG) is one of the key technologies in the context of energy transition. VSG can simulate the operation mechanism of a synchronous generator, so that the new clean energy power generation device can actively support the power grid, thus promoting the energy transition and improving the stability of the power grid. Firstly, the working principle of VSG is introduced, followed by clarifying the power coupling mechanism of VSG. Followed by stating the current popular power decoupling strategies, such as introducing voltage, current, or power compensation in the VSG control loop, decoupling methods based on virtual impedance and current compensation, and so on. After synthesising the different schemes, it is then pointed out that the different decoupling schemes have good performances under specific perspectives, but at the same time, they are limited by the conditions and have defects such as not being able to completely decouple and not being able to adapt to the situation under multiple machine connections. Finally, the research status of power decoupling of virtual synchronous machines is summarised, and the prospect of its research and future development is made.
