Abstract: Harmonics of a power output of a power plant at a point of common coupling between the power plant and a utility grid, wherein the power plant comprises a plurality of energy production units. The method comprises determining an electrical characteristic at the point of common coupling; determining the electrical characteristic at an output terminal of each of the energy production units and dispatching a control signal to at least one of the energy production units to control the electrical characteristic at an output terminal of the respective energy production units. The control signal is based on the measurement of the electrical characteristic at the point of common coupling and arranged for damping the harmonic of the power output of the power plant at the point of common coupling, wherein the control signal is determined on the basis of a predetermined prioritizing sequence of said electrical characteristic.

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: Controlling a current injected to a power grid from a renewable power plant, in response to a voltage event in the power grid At least a current at a point of common coupling between the renewable power plant and the power grid is determined and provided to a power plant controller (PPC). The power PPC derives individual current setpoint corrections for at least some wind turbines, based on the determined current, and dispatches each derived current setpoint correction to wind turbine controllers of the corresponding wind turbines. The wind turbine controllers control a current output of the respective wind turbines, based on measurements of current and/or voltage at a point of connection between the wind turbine and an internal grid of the renewable power plant, and by taking into account the dispatched current setpoint correction .

Abstract: According to embodiments described herein control of the auxiliary power system in a hybrid power plant is provided by determining a grid-draw threshold from an external power grid; monitoring power consumption for powered systems of the hybrid power plant; monitoring power generation of the hybrid power plant; discharging an alternative power source of one or more of an Energy Storage System (ESS) and an auxiliary generator in response to the power consumption exceeding the grid-draw threshold; and implementing prediction algorithms for power generation of the hybrid power plant and the power consumption. Accordingly, a source of power is managed between several alternative sources and the external power grid to meet plant operator defined criteria when maintaining power in various wind speed conditions.

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

Abstract: The invention relates to a method for correcting deviations of power produced by a power plant which includes at least one wind turbine generator and possibly other types of power generating units. The power deviations, i.e. deviations from a power reference for the power plant, are determined as energy errors. The invention addresses solutions for determining and compensating the energy errors.

Abstract: A method and associated control arrangement are disclosed for controlling a power output of a wind power plant (WPP) according to a predetermined power ramp rate limit, the WPP comprising a plurality of wind turbine generators (WTGs). The method comprises receiving a first signal indicating that a first WTG is in a ready state to begin producing power. The method further comprises, upon determining that, responsive to the received first signal, beginning power production of the first WTG at a predetermined default power ramp rate would cause the power output of the WPP to exceed the power ramp rate limit, controlling power production of the first WTG using at least one of: a first delay, a power ramp rate reference less than the default power ramp rate, and a power reference less than a nominal power output of the first WTG.
