Energy is an important driving force for social development. The shortage of natural resources urgently promotes the research of energy and the development of related technologies. Meanwhile, the distributed generation is one of the most important approaches. Virtual synchronous generator (VSG) technology, as a kind of control strategy that can participate actively in grid power regulation, has drawn much attention. Traditional VSG technology uses the two-level inverter as the main circuit. Based on the theory of VSG and the matrix converter (MC) as the main circuit of the VSG, the control system can imitate synchronous generator's characteristics such as inertial characteristics, frequency response characteristics and frequency modulation. The method provides a feasible solution for the power conversion of the distributed generation, which is the AC output, omitting the procedure of AC–DC–AC. Through the simulation, it is verified that the VSG technology can be applied to the MC, which provides a new idea for the exchange transformation in distributed generation.
