A method for augmenting an automatic generation control, AGC, of an energy management system grid, comprising: establishing a bilateral or unilateral communication between a grid energy management system and a wind plant control system of a wind plant; communicating a ramp rate limit signal from an automatic generation control of the grid energy management system; communicating wind plant control active power functions from the wind plant control system to the energy management system; wherein the wind plant control active power functions include undelivered wind power; characterized in that the step of communicating the ramp rate limit signal is performed in response to an area control error ACE, augmentation calculation performed by the AGC control determining that a ramp rate capability of AGC units is insufficient, comprising: augmenting the AGC when actual power exchange exceeds a first threshold resulting in a positive ramp rate limit on the wind plant; wherein if the power exchange continues to increase and exceeds a second threshold a zero ramp rate limit or cap is applied; wherein if the power exchange exceeds the first threshold for a specified amount of time then a negative ramp rate limit is sent to the wind plant to reduce power output; and wherein once the power exchange falls below the thresholds the ACE augmentation calculation is reset and the wind power plant allowed to generate according to the available wind with no ramp rate limit. establishing a bilateral or unilateral communication between a grid energy management system and a wind plant control system of a wind plant; communicating a ramp rate limit signal from an automatic generation control of the grid energy management system; communicating wind plant control active power functions from the wind plant control system to the energy management system; wherein the wind plant control active power functions include undelivered wind power; characterized in that the step of communicating the ramp rate limit signal is performed in response to an area control error ACE, augmentation calculation performed by the AGC control determining that a ramp rate capability of AGC units is insufficient, comprising: augmenting the AGC when actual power exchange exceeds a first threshold resulting in a positive ramp rate limit on the wind plant; wherein if the power exchange continues to increase and exceeds a second threshold a zero ramp rate limit or cap is applied; wherein if the power exchange exceeds the first threshold for a specified amount of time then a negative ramp rate limit is sent to the wind plant to reduce power output; and wherein once the power exchange falls below the thresholds the ACE augmentation calculation is reset and the wind power plant allowed to generate according to the available wind with no ramp rate limit. augmenting the AGC when actual power exchange exceeds a first threshold resulting in a positive ramp rate limit on the wind plant; wherein if the power exchange continues to increase and exceeds a second threshold a zero ramp rate limit or cap is applied; wherein if the power exchange exceeds the first threshold for a specified amount of time then a negative ramp rate limit is sent to the wind plant to reduce power output; and wherein once the power exchange falls below the thresholds the ACE augmentation calculation is reset and the wind power plant allowed to generate according to the available wind with no ramp rate limit.
