| 摘要 |
The present disclosure relates to a microgrid (1) comprising at least a first distributed generator (DG) (4a); a direct current (DC) bus (6); an alternating current (AC) bus (5); a switch (3) arranged for connecting the AC bus to a power grid (2); a DC to AC converter (7) for connecting the first DG to the AC bus; a first power controller (8a) for controlling power exchange between the first DG and the DC bus; and a converter controller (9) of the DC to AC converter for controlling an output of the first DG to the AC bus. The converter controller is configured for controlling the DC to AC converter in a first mode when the first power controller is configured not to allow any power exchange between the first DG and the DC bus, and in a second mode when the first power controller is configured to allow power exchange between the first DG and the DC bus. |
