Abstract :
Micro-grids (MG) are expected to be low inertia grids especially due to the deployment of power electronics used to connect distributed generation (DG) units. This issue brings consequences on the grid dynamics, reducing the frequency stability margins. To this end, the emulation of synchronous machines has been proposed as a possible alternative. This paper explores the benefits of this concept comparing the dynamic performance with respect to the conventional droop control.
