<p>A method and a system to influence the power generation of at least one adjustable speed generator (9) are presented. The system comprises a first voltage source converter (4) connected to a local AC bus (2), where the local AC bus (2) is provided with power by the at least one adjustable speed generator (9), a second voltage source converter (6) connected to an AC grid (8), a DC link (5) connected between the first (4) and the second (6) voltage source converter, and at least one control unit (18) to control the first (4) and the second (6) voltage source converters. The at least one control unit (18) performs the method to control the AC voltage (V<SUB>loc</SUB>) in the local AC bus (2) via the first voltage source converter (4) and to modify a reference value for the AC voltage magnitude (V<SUB>loc,ref</SUB>) of the local AC bus (2) in dependence on the AC voltage magnitude (V<SUB>grid</SUB>) of the AC grid (8).</p> |
