Abstract:
A power generator controller comprising:a power system monitor monitoring current status of each of a plurality of power generators of a power system and demand for electricity from the power system; and a power-generator-output-optimizing-part solving an objective function in consideration of a balancing constraint balancing supply of power from the generators and demand for electricity from the power system and determining an output of each of the power generators of the power system at each of a plurality of intervals, the objective function requiring minimized total cost of power generation subject to the balancing constraint, wherein the power-generator-output-optimizing-part solves the objective function in further consideration of automatic frequency control (AFC) capacity, based on an upper limit of rate of change of the power output of each of the power generators.
