Abstract: Controlling a renewable energy power plant, such as a wind power plant, when a frequency level of a power network, to which the power plant is connected, is outside of a frequency deadband. Aspects of the invention may be used to control the active power output of a wind energy power plant and to dampen oscillations in the controlled power characteristic when the frequency level of the connected power network is fluctuating outside of the frequency deadband.

Abstract: A wind power plant has a plurality of wind turbine generators and a power plant controller arranged to communicate with the plurality of wind turbines generators. Each wind turbine generator has a controller arranged to control an active power output in its respective wind turbine generator according to an active power set point received from the wind power plant controller. A change in the active power reference changes the active power set point for each wind turbine generator by a weighting factor.

Abstract: Aspects of the present invention relate to methods for controlling active power output of a wind turbine generator in response to a frequency event on a power network to which the wind turbine generator is connected, wherein the active power output of the wind turbine generator is limited to be below an upper active power limit and/or above a lower active power limit. The methods comprise determining and dispatching active power references to a controller of the wind turbine generator for controlling the wind turbine generator. The methods operate to ensure that the value of the active power reference immediately after the frequency event is within the allowable active power range, thereby avoiding any mismatch between the reference and the output that may cause a delay in returning to normal operation.

Abstract: In various embodiments of the present disclosure, there is provided a method of controlling active power generation of a wind power plant coupled to a power grid, the wind power plant including a power plant controller for controlling a plurality of wind turbine generators. In an embodiment, the method includes monitoring an operational status of a plant compensation equipment and adjusting a plant reactive power capability when the operational status of the plant compensation equipment indicates a fault in the plant compensation equipment. According to an embodiment, the method includes controlling the wind power plant to curtail the active power generated by the wind power plant by a curtailment amount determined based on the adjusted plant reactive power cap ability. A corresponding wind power plant is further provided.

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.
