Abstract: Aspects of the present invention relate to a method (200) for controlling active power output of a renewable energy power plant (12) comprising one or more renewable energy generators (14). The method (200) comprises: while a measured frequency level of a power network (16) to which the power plant (12) is connected is within a frequency deadband: determining an estimated active power output from the power plant (12) according to a model (101) of the power plant (12) and one or more model inputs; and determining a measured active power output from the power plant (12); and when the frequency level of the power network (22) is outside the frequency deadband: determining an estimate of available active power for the power plant (12) to supply according to the model (101) of the power plant (12) and one or more model inputs; determining an estimate correction factor based on a comparison of the estimated active power output with respect to the measured active power output; correcting the estimate of available active power based on the estimate correction factor to provide a corrected estimate of available active power; and determining and dispatching active power set points for controlling the one or more renewable generators (14) of the power plant (12), the set points being determined based on the corrected estimate of available active power and the frequency level. Aspects of the invention may be used to control the active power output of a wind energy power plant (12) and to determine accurate estimates of the available active power when the frequency level of the connected power network (16) is outside of the frequency deadband.

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.

Abstract: The invention relates to a power plant controller for controlling wind turbine generators. More particularly, the invention relates to a method for compensating data obtained from measurements at a connection point to the grid in case of a communication failure where communication of such data is lost or becomes unreliable. The measured data are used in the power plant controller for determining setpoints for controlling the wind turbine generators' production of active and reactive power. In response to detection of a communication fault a new setpoint is determined independently of new measured grid data by reconfiguring parts of the power plant controller.

Abstract: The invention relates to a method for operating a group of wind turbines in a wind power plant coupled to a utility grid, comprising the steps of determining that a wind turbine should be deactivated in response to receiving a power curtailment command from the grid, and retrieving data from each wind turbine in the group of wind turbines. Further, the method comprises ranking all the wind turbines according to a set of ranking criteria and based on the retrieved data, and selecting a wind turbine to be deactivated based on the ranking. Further, the steps of data retrieval and ranking of all the wind turbines including any deactivated wind turbines in the group are repeated at time intervals, and the wind turbine to be deactivated is re-selected based on this updated ranking. The data may include a down time for any presently deactivated wind turbine in the group of wind turbines, reflecting for how long time the wind turbine has been presently deactivated, and the set of ranking criteria may then comprise a pause criterion taking into account the down time.

Abstract: This invention relates to a method and a power plant controller arranged to carry out the method. The method is on an intelligent dispatching of the power production to wind turbines and optional compensation equipment of a wind power plant, as the power producing units of a wind power plant. The invention relates to a case where the requested produced power is less than the total capacity of the power plant, and the invention relates to utilizing this situation to dispatch set points to the wind turbines and the compensation equipment in a flexible way. This flexibility may increase the wind turbines' life time, help in scheduling maintenance and expand the electrical operating range of the wind power plant. The determination of the set points on active and reactive power is a combined determination of both set points for each of the energy producing units of the wind power plant.
