Driven by inertial demand from the grid, the virtual synchronous generators (VSGs) are widely utilized in distributed generation systems. However, harmonic sources in the distributed generation systems with high grid impedance will cause grid voltage distortion. Distorted voltage greatly affects the power quality of VSG. Moreover, it is difficult to …

The hardware parameter adjustment and model construction for the VSG grid-connected inverter are carried out. By combining the basic principles of synchronous generators, a simulation model of the ship''s synchronous generator unit is constructed, and an overall model of the PV-ship energy distribution network is established.
Due to the increasing penetration of renewable energy resources in distribution power systems, maintaining system stability has grown as a major concern in system operation. The distributed generators (DGs) used in the microgrid are interconnected to the grid through power electronic converters which do not provide any mechanical inertia due to …

VSG technology achieves power exchange between the DC side and the system by controlling the inverter. Traditional VSG control strategies suffer from issues such as long transient adjustment times, poor stability, and steady-state deviations.
Since the network reduction model is used in this paper, the following simplifications are made to the above VSG model: (i) the active power and reactive power from the inverter bridge node, instead of the terminal node, are taken as the P i and Q i in the VSG control and (ii) the inverter bridge voltage instead of the terminal voltage is adopted in the VSG …
The general and simple swing equation of SG is used as a core part of VSG, and it is stated as [19], [46]: (3) P m-P e = 2 J d ω dt-D (ω-ω r) ω where P m is the inverter input power, P e is the output electrical power of the inverter.
Both droop control and virtual synchronous generator (VSG) control can be widely seen used in voltage source inverter. Among them, the virtual inertia and damping characteristics VSG control has the ability to provide virtual inertia factors that droop control does not have, but its active power response speed is very slow, and there is a large overshoot. Aiming …

The VSG inverter will regulate the frequency and the PQ inverter will follow along. If the inverter has an LCL filter then a discrete Luenberger observer can be implemented to estimate the current through the second inductor and the voltage over the capacitor.
Virtual Synchronous Generator (VSG) is proposed as a control strategy applied to the inverter for power system stability enhancement by imitating the behavior of a synchronous generator.
