Damping

DC microgrid damping ratio

To suppress the voltage oscillations in DC MGs, various damping stabilization techniques are proposed by researchers. . From this point of view, this paper analyzes the interaction between source and load converters constituting the DC microgrid using the derived mathematical input and output impedances models. This paper proposes a stability improvement method using the analyzed result. A parallel combination of a photovoltaic (PV) system, a rectifier and a batte y are used as a hybrid power conversion system (HPCS).
