Abstract

The invention relates to a power system comprising a first power source from a power grid with an AC multi-phase input and a second power source being a variable speed generator, which are respectively capable of supplying power to a DC link, wherein the first power source is connected to a first input power converter being provided as an active rectifier and wherein the second power source is connected to a second input power converter, further comprising at least one output converter being connected to the DC link to supply power to a load, wherein a control system is connected to the first input power converter, the second input power converter and the output converter, which controls the flow of energy from the power grid's AC input to the DC link, the flow of energy from the generator to the DC link and the flow of energy from the output converter to the load, so as to predominantly utilize all the available energy from the grid. The invention further relates to a method for operating such a system.
