Virtual inertia with PV inverters using DC-link capacitors [PDF]
2016 18th European Conference on Power Electronics and Applications (EPE'16 ECCE Europe), 2016 Soon, virtual inertia for grid control must be covered by photovoltaic inverters. It is suggested to use DC link capacitors for this task. This requires 5 W, 50 J and a capacitor size of about 200 cm3 per installed kW, corresponding to the size of single phase DC link capacitors. It is shown that the additional power ripple (and thus current ripple) is
