Abstract

This paper proposed a new decentralized control method for two different power-rated energy sources equipped with DC-DC switching power converter formed as distributed generations (DG) supply DC microgrid. If each DG has passivity property, one can apply this control for all DGs. The model of the considered system is presented using a well-known port-Hamiltonian matrix. Thereby, with an interconnection and damping assignment—passivity-based control (IDA-PBC), global stability is guaranteed. Moreover, applying droop voltage control to change the state-variable references allows for the current sharing between the two DG. To validate the proposed method, simulation results are provided.
