Claim 0:
1. A hybrid power plant connected to an associated electrical grid for producing power to said electrical grid, the hybrid power plant comprising a plurality of energy assets, the plurality of energy assets comprising:
a first renewable power generating unit, said first renewable power generating unit comprises a plurality of wind turbine generators,
a second renewable power generating unit, wherein the second renewable power generating unit is different from the first renewable power generating unit, and
an energy storage unit, said energy storage unit being capable of storing energy from said first and second renewable power generating units, and delivering power to said electrical grid when required,
wherein the hybrid power plant further comprises a power plant controller arranged to communicate with the plurality of energy assets, the power plant controller being arranged for
receiving an active power reference and performing a first comparison of said active power reference with an available power from said first renewable power generating unit and said second renewable power generating unit, wherein the available power is defined by power which a given renewable power generating unit is able to produce, and
performing a second comparison of an available charging, or discharging, capability of the energy storage unit with a result of said first comparison, and distributing a corresponding set point to said energy storage unit, and
the power plant controller further being arranged, in response to the result of said first comparison, for distributing set points to said first renewable power generating unit and said second renewable power generating unit, respectively,
so as to deliver power from the hybrid power plant in accordance with the received active power reference, and
wherein the power plant controller is further arranged for distributing set points to at least one of said first renewable power generating unit and said second renewable power generating unit, respectively, that are above the available power from said first renewable power generating unit and said second renewable power generating unit.
