Abstract:
1. A power plant for controlling power output to a power grid, the power plant comprising: a wind farm including a plurality of wind turbines configured to generate and output a wind farm power signal to a point of common connection, each wind turbine of the plurality of wind turbines including a grid power converter connected to the point of common connection and configured to receive the wind farm power signal and output a power signal for the power grid; a sensor to measure a frequency of the power grid; and a supervisory controller coupled in communication with each of the plurality of wind turbines of the wind farm, the grid power converter, and the sensor, the supervisory controller configured to implement a control algorithm to dynamically adjust the power signal in response to the frequency measured by the sensor dropping below a first target frequency by:
