A method for improved power ramping in a hybrid power plant

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 comprising:

• a plurality of first energy assets, wherein the first energy assets comprise a wind turbine generator;
• at least one second energy asset, the second energy asset being different from a wind turbine generator, preferably said second energy asset comprise a solar power unit;
• and
• at least one third energy asset comprises an energy storage unit, preferably a battery energy storage system,
• wherein the hybrid power plant further comprises a power plant controller arranged to communicate with said plurality of energy assets, the power plant controller being arranged to receive a power reference defining a power to be delivered to the electrical grid and calculating therefrom, and dispatching, a power setpoint to each energy asset, each energy asset having an individual ramp rate which adds to a power ramp rate of the hybrid power plant;
• wherein each energy asset further has a ramp rate capability defined as the highest possible ramp rate at a given time;
• and
• wherein the power plant controller is arranged for:
• receiving from each energy asset the corresponding ramp rate capability;
• and
• taking into account the plurality of ramp rate capabilities from the energy assets when calculating the power setpoint to each energy asset, so as to improve the power ramp rate control of the hybrid power plant.
