摘要： A system and method are provided for damping power system oscillations in a power system network having one or more local inverter-based generators within a plant, the plant connected to a grid at a point of intersection (POI). The system and method include a plant-level controller or local controller that receives one or more grid signals having a characteristic indicative of a power system oscillation. The plant-level controller or local controller generates an auxiliary signal from the grid signals that is used by the local controller of the inverter-based generators. At the local controller, the auxiliary signal is used to modulate reactive power output from the inverter-based generator to change a voltage at the POI, the voltage change damping the power system oscillations.

摘要： The system and method described herein provide control for a power generating asset having a double-fed generator connected to an electrical grid. Accordingly, a non-deliverable component and a deliverable component of a total power output of a generator of the power generating asset is determined via a controller. A compensation module of the controller then determines a first control signal based, at least in part, on the non-deliverable component. The first control signal is configured to establish a modified rotor current setpoint. Additionally, a buffer module of the controller then determines a buffer control signal for a DC energy buffer based, at least in part, on the non-deliverable component. The DC energy buffer is operably coupled between a line-side converter and a rotor-side converter of a power converter of the power generating asset. In response to the first control signal and the buffer control signal the non-deliverable component is delivered to the DC energy buffer via the line-side converter, thereby precluding the delivery of the non-deliverable component to or from the electrical grid. The deliverable component of the total power output of the generator is delivered to the electrical grid.

摘要： A system and method are provided for controlling a power generating system having at least one power generating subsystem connected to a point of interconnection (POI). A first data signal is obtained corresponding to a feedback signal of an electrical parameter regulated at the POI, the first data signal having a first signal fidelity. A second data signal indicative of the electrical parameter generated at the power generating subsystem is obtained, the second data signal having a second signal fidelity that is higher than the first signal fidelity. A correlation value between the first and second data signals is obtained by filtering a value difference between the first and second data signals. The correlation value is applied to a setpoint value for the electrical parameter regulated at the POI. The modified setpoint value and the second data signal are combined to generate a setpoint command for the power generating subsystem that is used for controlling generation of power at the power generating subsystem to regulate the electrical parameter at the POI.

摘要： A method for controlling a power system includes generating, via at least one inverter-based resource, one or more command signals via a regulator of at least one inverter-based resource of the power system. Further, the method includes dynamically estimating, via the at least one inverter-based resource, a reactive power capability of the at least one inverter-based resource based, at least in part, on the one or more command signals. Further, the method includes sending, via the at least one inverter-based resource, the reactive power capability to the system-level controller. Thus, the method includes controlling the power system based on the reactive power capability.

摘要： The present subject matter is directed to a system and method for regulating reactive power in a wind farm connected to a power grid so as to improve reactive speed-of-response of the wind farm. The method includes receiving a voltage feedback from the power grid and a voltage reference and calculating a linear voltage error as a function of the voltage feedback and the voltage reference. A further step includes generating a first output based on the linear voltage error via a first control path having a first voltage regulator. A further step includes determining a non-linear voltage error based on the linear voltage error via a second control path having a second voltage regulator. A second output is generated via the second control path based on the non-linear voltage error. As such, a reactive power command is generated as a function of the first and second outputs.

摘要： Power generation stabilization control systems and methods include monitoring a frequency of the power grid. In response to detecting a frequency event occurring in the power grid, the method includes activating a control scheme in order to meet one or more grid requirements of the power grid. The control scheme includes increasing a power output of the wind turbine to, at least, a pre-event measured grid power. Further, the control scheme includes calculating a power correction factor for a power set point as a function of, at least, the frequency event. Moreover, the control scheme includes adjusting the power set point via the power correction factor such that the power output follows a predetermined trajectory. In addition, the control scheme includes controlling, via a turbine controller, the wind turbine based on the adjusted power set point for as long as the control scheme is activated.

摘要： The present disclosure is directed to a system and method for stabilizing disconnection of one or more wind turbines in a wind farm connected to a power grid during one or more grid contingency events. The method includes determining, via one or more processors, a phase-locked loop error signal for each of the wind turbines based on sensor signals from the plurality of wind turbines. The method also includes comparing the phase-locked loop error signal of each wind turbine to at least one predetermined threshold for a predetermined time period. If the phase-locked loop error signal for one or more of the wind turbines comprises a positive value that exceeds the predetermined threshold for the predetermined time period, then the method includes generating a trip signal for the one or more of the wind turbines based on the phase-locked loop error signal, the positive value being indicative of system instability, wherein the trip signal is configured to disconnect the one or more wind turbines from the power grid.
