Apparatus and method for predictive control of a power generation system

An apparatus for controlling a power system control area during a plurality of consecutive automatic generation control cycles to ensure compliance with a first control performance standard at an end of a rolling first compliance period and compliance with a second control performance standard at an end of a second fixed compliance period, the apparatus comprising:

• a memory for storing area control error values determined from operational of the power system control area;
• a first module executable by a processor for determining a first measure of the first control performance standard responsive to the area control error values from a beginning of a first compliance period to the time at which the first measure is determined;
• a second module executable by the processor for determining a second measure of the second control performance standard responsive to the area control error values from a beginning of a second compliance period to the time at which the second measure is determined;
• a third module executable by the processor for determining a first area control error target responsive to the first measure and to a compliance target for the first control performance standard, and for determining a second area control error target responsive to the second measure and to a compliance target for the second control performance standard;
• a fourth module executable by the processor for determining a first control performance standard correction value responsive to the first area control error target and for determining a second control performance standard correction value responsive to the second area control error target;
• and
• a fifth module executable by the processor for controlling the power system control area according to one or both of the first and the second control performance standard correction values, wherein if both the first and the second control performance standard correction values are in a same direction, controlling the power system according to a larger of the first and the second control performance standard correction values, wherein if the first and the second control performance standard correction values are in opposite directions, controlling the power system according to the second control performance standard correction value.
