| Popis: | This work presents a stability analysis of a solar photovoltaic (PV) system applied in an experimental smart microgrid. The system totals 20 kW at rated conditions, composed of 10 units of 2 kW, where each unit is fed by a photovoltaic string and a three-state switching cell-based boost dc-dc converter, accordingly connected to the dc-bus of a smart microgrid. Furthermore, with an approach on operation modes, small-signal models are developed to determine the equivalent impedances, used in the stability criteria. As a means to verify the operation and stability of the solar photovoltaic system, experimental results are presented, including a hardware demonstrator of a single dc-dc converter. |
