An Adaptive Virtual Inertial Control Strategy for DC Distribution Networks

Energies
The DC distribution network is a low-inertia system, which is very sensitive to load disturbance, system failure, and other factors. By adding virtual capacitance to the converter connected to the power supply, the virtual inertia of the DC power grid ...

Current-limiting droop control with virtual inertia and self-synchronization properties [PDF]

IECON 2017 - 43rd Annual Conference of the IEEE Industrial Electronics Society, 2017
In this paper a current-limiting droop control of grid-tied inverters that introduces virtual inertia and operates without a phase locked loop unit is proposed. The proposed controller inherits a self-synchronization function and can guarantee tight bounds for the inverter frequency.
