Integrated hybrid power plants for off-grid systems

A method for determining the power ratings of a plurality of power units being operatively connected to an internal power grid of a hybrid power plant, the method, comprising:

• determining respective power ratings of the plurality of power unit in accordance with active and reactive power losses in the internal power grid in order to obtain optimal operation of the hybrid power plant.

A hybrid power plant, comprising:

• a plurality of power units being operatively connected to an internal power grid, wherein respective power ratings of the plurality of power units of the hybrid power plant are determined in accordance with active and reactive power losses in the internal power grid in order to obtain optimal operation of the hybrid power plant;
• wherein the internal power grid comprises a first voltage bus and a second voltage bus;
• wherein the first voltage bus is configured for a lower voltage than the second voltage bus, the second voltage bus being operatively connected to the first voltage bus via one or more transformer units, wherein the total power rating of the plurality of power units is below 5 MW.
