A hybrid power plant and a method for controlling a hybrid power plant

A method for controlling a hybrid power plant, the hybrid power plant being 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 comprising a plurality of wind turbine generators,
• a second renewable power generating unit, said second renewable power generating unit comprising a plurality of solar power units, and
• a battery energy storage system, said battery 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,
• the method, comprising:
• controlling 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 correspondingly distribute active power set points to the plurality of energy assets, and
• receiving information indicative of a power limitation from the battery energy storage unit, and dynamically modify the active power set points by corresponding weighting factors according to the capabilities of the respective energy assets in response to said power limitation so as to produce active power from the hybrid power plant accordingly.

A power controller for controlling an associated 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:
