1. A power generation system for meeting a power demand of a power consumption unit, comprising:

  • a chiller for regulating a temperature of the power consumption unit;

    a heat storage unit for supplying heat to the chiller;

    an electric power system of the power consumption unit for providing electrical power to the power consumption unit and to the chiller;

    a power supply device configured to supply power to the electric power system; and

    a processor configured to determine a schedule for supplying power to the electric power system using the at least one power supply device, wherein the processor;

    creates an objective function for operating the at least one power supply device that includes a forecasted power demand scenario of the power consumption unit and a probability of occurrence of the power demand scenario,locates a substantial minimum of the objective function to determine the schedule for operating the at least one power supply device to meet the power demand scenario, wherein a relation between a fuel consumption of the power supply device and a power output of the power supply device is represented using a piece-wise linear function, andoperates the at least one power supply device according to the determined schedule.
