Abstract: A method of controlling a wind turbine. The wind turbine is controlled during a variable speed period in accordance with a variable speed region of a partial load speed curve so that a power of the wind turbine is below a rated power and a generator speed of the wind turbine is below a rated generator speed. During a boost period the wind turbine is controlled in accordance with a boost region of the partial load speed curve so that the power is below the rated power and the generator speed is above the rated speed. During a full load period the power is at the rated power and the generator speed is at the rated speed.

Abstract: Power production forecast based wind turbine control A method is provided for determining a power production capacity of at least one wind turbine (10) connected to a power grid. The method includes receiving, e.g. from a power grid control centre (40), a power production forecast for the at least one wind turbine (10), and then monitoring an actual grid frequency of the power grid. Based on the actual grid frequency and a nominal grid frequency, a frequency support power reserve is determined. The power production capacity is then determined in dependence of the determined frequency support power reserve and the power production forecast

Abstract: The invention relates to a method for controlling power generation from a power plant (100) which comprises a plurality of power generating units. The method involves setting a maximal allowed power production (Pmax) for each power generating unit in a selection of one or more power generating units of second priority (pl2) to a non-zero value, where the maximal allowed power production (Pmax) is determined dependent on whether a first power production gap (Pgap1) is greater or less than zero and dependent on a comparison of the first power production gap (Pgap1) with a second available power production capability (Paval_pl2) of the selection of the one or more power generating units of the second priority (pl2).

Abstract: The invention relates to a method for reducing peak power consumption of a grid connected power plant which comprises a plurality of wind turbines. In response to determining that a power production value of the power plant is below a power threshold the following steps are performed: after a first time delay of a first group (TD11) of one or more wind turbines, control the first group (WTG1) to initiate and operate in a power saving mode (201) for a predefined first power saving period of the first group (Tin11), and after a first time delay of a second group (TD21) of one or more other wind turbines, control the second group (WTG2) to initiate and operate in the power saving mode for a predefined first power saving period of the second-group (Tin21). The first time delay of the first group (TD11) is less than the first time delay of the second-group (TD21) and the power saving mode inhibits a power consuming activity for the wind turbines operating in the power saving mode.

Abstract: The invention relates to a method for controlling injection and absorption of reactive power in a wind power plant (WPP). In addition to wind turbine generators (WTG), the wind power plant comprises reactive power regulating devices, such as MSU and STATCOM devices. The reactive power regulating devices are controlled by wind power plant controller so that the combined amount of reactive power produced by the wind turbine generators and the reactive power regulating devices satisfies a desired amount of reactive power. In case of communication fault between the power plant controller and one of the reactive power regulating devices, the power plant controller is reconfigured so as to compensate the capability of the reactive power regulating device to inject or absorb the amount of reactive power.

Abstract: A method for controlling a current injected to a power grid (2) from a renewable power plant (1), in response to a voltage event in the power grid (2), is disclosed. Occurrence of a voltage event in the power grid (2) is detected. At least a current at a point of common coupling (3) between the renewable power plant (1) and the power grid (2) is determined, and the determined current is provided to a power plant controller (4). The power plant controller (4) derives individual current setpoint corrections for at least some wind turbines (5) within the renewable power plant (1), based on the determined current, and dispatches each derived current setpoint correction to wind turbine controllers (6) of the corresponding wind turbines (5). The wind turbine controllers (6) control a current output of the respective wind turbines (5), based on measurements of current and/or voltage at a point of connection (8) between the wind turbine (5) and an internal grid (7) of the renewable power plant (1), and by taking the current setpoint correction dispatched from the power plant controller (4) into account.

Abstract: A method for controlling a power output of a power generating unit (18, 21) is disclosed. An accumulated power output of the power generating unit (18, 21) during a predefined time interval is forecasted. An actual power output of the power generating unit (18, 21) is measured during the predefined time interval, and an actual accumulated power output is estimated for the predefined time interval on the basis of the measured actual power output of the power generating unit (18, 21). A difference between the forecasted accumulated power output and the estimated actual accumulated power output is derived. The power output of the power generating unit (18, 21) is boosted, in the case that the estimated actual accumulated power output is below the forecasted accumulated power output, and the difference between the forecasted accumulated power output and the estimated actual accumulated power output is larger than a predefined threshold value.

Abstract: Embodiments provide for the control of a power plant including several generators by setting a reference frame for the generators with a first and a second axis; measuring a grid demand voltage at the shared connection point; determining active and reactive currents required at the shared connection point based on the grid demand voltage and grid codes; transforming the active and reactive currents required at the shared connection point to the reference frame where the first axis defines a first current set point and the second axis defines a second current set point; and dispatching the first and second current set points to generator controllers associated with each generator. Current set points may be generated for positive/negative frames, direct quadrature frames, real/imaginary frames and may be set evenly for all generators or adjusted per generator.
