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: The present invention relates to a state machine for controlling a wind power plant (WPP), comprising at least one wind turbine connected to an electrical grid, the state machine is adapted to, receive a plant power reference (P_total) according to at least one electrical value of the electrical grid, manage a plurality of control modes and output signals, in relation to the plurality of control modes, select within the control modes, according to controller inputs and contingency at that moment in time, transfer the corresponding control values to a power controller, and dispatch a power reference to each of the at least one wind turbines according to the selected control mode. The invention also relates to a control system arranged to control power output of a wind power plant (WPP), comprising at least one wind turbine connected to an electrical grid, and the control system having a state machine.

Abstract: The invention relates to a control system for a wind turbine generator, WTG. The control system defines reactive limits for a reactive power reference for the WTG. The reactive limits are defined as a function of a physical parameter, e.g. the output voltage of the WTG. In case the reactive power reference exceeds the predefined limits, the reactive power reference is limited. By limiting the reactive power reference output voltages which exceed certain output voltage limits may be avoided and, thereby, a disconnection of the WTG from the grid may be avoided.
