In this paper, the virtual synchronous generator (VSG) concept in grid feeding structure is investigated within a week grid in order to bring support capabilities to the frequency and amplitude deviation. The frequency at the point of common cohesion (PCC) can be reduced when more active power is required whereas the voltage amplitude is reduced with reactive power demand. The small signal modeling of the VSG is addressed taking into consideration parameters variation to obtain a smooth power flow transition and then low frequency nadir. In order to validate the theoretical concepts, simulation tests have been carried out using PSIM platform.
