“When the virtual synchronous generator is connected to the medium and low voltage distribution network, the impedance of the line is inductive, resulting in strong power coupling, oscillation, and control deviation, which affects the quality of electrical energy and transmission stability. Researchers introduced the concept of virtual capacitors and proposed an improved power decoupling strategy. The coupling mechanism was analyzed through small signal modeling and verified on the MATLAB/Simulink platform. This strategy weakened the interference of active command changes or load switching on reactive power, suppressed the phenomenon of strong power coupling in the dynamic process of the system, and provided a new solution to solve the problem of VSG power oscillation.”
