    Abstract: The invention relates to a method for controlling a power plant (100) for providing frequency support to a power grid. The power plant comprises an electrical storage unit (150) and a power generating system (110) comprising one or more power generating units (101) including at least one wind turbine generator (102). The method comprises setting a frequency control period, wherein the electrical storage unit is scheduled to charge or discharge according to a first power set-point and at the start of the frequency control period, charging or discharging the electrical storage unit according to the power set-point. In case of a frequency deviation, a power change of the power from the electrical storage unit is determined based on the frequency deviation. Frequency support is provided by controlling the electrical storage unit to charge or discharge according to a second power set-point determined from the power change.

    Abstract: The invention relates to a hybrid power plant (100) for producing power to the electrical grid, the hybrid power plant comprising a plurality of energy assets; a first renewable power generating unit, such as wind turbine generators (WTG1, WTG2), and an energy storage unit (EA3, ESU), preferably a battery energy storage system (BES). The hybrid power plant has a power plant controller (PPC, 200) arranged to communicate with the plurality of energy assets, and, when an under-frequency event occurs, the energy storage unit (ESU, BES) provides frequency support during the under-frequency event (UFE) by providing additional power (ΔP) as a function of a state of charge (SoC) of the energy storage unit at the time when the under-frequency event occurs (SoC_mem). Thus, during an under-frequency event, it is possible to obtain a more stable power output from the hybrid power plant.
