A Three-Parameter Adaptive Virtual DC Motor Control Strategy for a Dual Active Bridge DC–DC Converter

Increasingly more power electronic devices are being connected to DC microgrids, which reduces the inertia of a microgrid, and bus voltage has poor resistance disturbance. Adding virtual motor control converter can effectively suppress fluctuation voltage; however, due fixed damping parameters, system cannot attain good dynamic performance. On this basis, two-parameter adaptive is proposed realize flexible change both in terms damping, improves stability bus, performance under control. To further improve flexibility microgrid control, paper, dual active bridge (DAB) DC–DC controlled by phase shift (DPS) taken as research object, three-parameter strategy adjustment inertia, armature at same time, meanwhile, optimize backflow inductor current stress converter. Finally, simulation experiment results show that compares with strategy, it reduce recovery system. The rate reduced 9%, time only 0.18 s; optimization also stress.
