Paper Title - Study and Performance of Virtual Synchronous Generator
Compared to the conventional bulk power in which the synchronous machine dominates, the distributed
generator/renewable energy sources unit have either very small or no rotational mass & damping property which plays a
significant role in the grid stability. A solution towards stabilizing such a grid is to provide additional inertia virtually. A virtual
inertia can be established for distributed generator/ renewable energy sources by using short term energy together with a power
electronics inverter/converter & a proper control mechanism. This concept is known as virtual synchronous generator. This
paper presents virtual control strategy based on voltage and frequency stability of the machine. Moreover, a virtual
synchronous generator system is established based on the mathematical model of synchronous generator. The proposed design
method has been validated through simulations, showing good response performance of synchronous generator.
