TY - GEN A1 - Jaramillo-Cajica, Ismael A1 - Schiffer, Johannes T1 - A Dwell-Time Approach for Grid-Aware Operation of a Distributed Generator in an Islanded DC Microgrid T2 - 2022 European Control Conference (ECC) N2 - We propose a switched control law for a DC-DC Buck converter that enables a grid-aware operation of a distributed generator (DG) in a low-voltage islanded DC microgrid (MG). The qualifier grid-aware means that the DG adjusts its operation mode in dependency of the MG status. The resulting closed-loop system is a switched system, in which the subsystems possess different equilibrium points. By means of a time- and state-dependent switching logic together with dwell-time stability analysis methods, we derive sufficient stability criteria that ensure the existence of a unique and globally exponentially stable equilibrium point of the resulting closed-loop switched system. The performance of the proposed control is illustrated via a numerical example.
