摘要
A microgrid connecting at least one distributed electricity generator includes a first switch configured for, in a closed position, connecting the microgrid to a first network line at a first point of common coupling (PCC) and for, in an open position, disconnecting the microgrid from the first network line at the first PCC; a second switch configured for, in a closed position, connecting the microgrid to a second network line at a second PCC, and for, in an open position, disconnecting the microgrid from the second network line at the second PCC; and a control unit configured for, when an islanding event has been detected when the second switch is in its closed position and the first switch is in its open position, acting to close the first switch, bringing it to its closed position.
