Virtual DC machine: an inertia emulation and control technique for a bidirectional DC–DC converter in a DC microgrid

IET Electric Power Applications, 2018
In a DC microgrid (DCMG), the DC bus voltage is vulnerable to the power fluctuations caused by the variations of intermittent renewable energy sources and local loads. A concept is developed to operate a bidirectional DC–DC converter as a DC machine to mimic the inertia characteristic of a DC machine and regulate the DC bus voltage fluctuations during ...
