Abstract: Systems and methods for controlling wind turbines providing reactive power are provided. In particular, a method for controlling a power system that includes a controller and one or more wind turbines electrically connected to a power grid through a point of interconnection can be provided. The method can include receiving signals from a sensor associated with the wind turbines. The method can also include determining wind turbines that are operating in low wind or no wind operating conditions based, at least in part, on the one or more of the sensor signals. The method can also include determining a reactive power capability of the wind turbines operating in low wind or no wind conditions and generating control signals based, at least in part, on the reactive power capability of the wind turbines. The method can also include controlling an operational state of the wind turbines based on the control signals.

Abstract: Systems and methods for managing or controlling resonance in wind turbine power systems are provided. In particular, a method for controlling a power system that includes a central master controller and one or more wind turbines electrically connected to a power grid through a point of interconnection can be provided, where each wind turbine includes a voltage regulator. The method can include receiving, by the controller, a signal from a sensor associated with wind turbines and determining, which wind turbines are operating in conditions indicative of a resonance condition in the wind turbine electrical power system based, at least in part, on the sensor signals. The method can also include generating one or more control signals based, at least in part, on a power requirement at the point of intersection and controlling an operational state of each of the voltage regulators based on the control signals.

Abstract: The present disclosure is directed to a system and method for balancing reactive power loading between multiple renewable energy power systems coupled to a power grid at a point of regulation (POR). The method includes determining a voltage error based on a voltage reference and a measured voltage at the POR. The method also includes measuring at least one operating condition from each of the power systems. Further, the method includes determining a per unit actual reactive power for each of the power systems based on at least one of the actual operating conditions and determining a per unit average reactive power from the power systems based on at least one of the actual operating conditions. Thus, the method also includes determining a voltage reference command for each of the power systems as a function of the voltage error, the per unit reactive power, and/or the per unit average reactive power.
