The concept of the virtual synchronous generator (VSG) is emerging as an attractive solution for controlling grid-connected inverter when renewable energy has a high penetration level into grid. This paper focuses on small-signal modeling and parameters design power loop VSG, points out that bandwidth should be far less than twice line frequency purpose avoiding VSG output voltage to severely distorted. Consequently, line-frequency-averaged model derived system analysis design. Based model,...
