C1,Gen=2P1,Gen；
The cost of electricity-generating of second generator unit and the functional relation of generated output：
C2,Gen=P2,Gen 2；
Then the power supply control apparatus determines that the object function of the micro-capacitance sensor is：
min（2P1,Gen*P1,Gen+P2,Gen 2*P2,Gen）.
The power supply control apparatus determines the hair of first generator unit and second generator unit by above-mentioned constraints The power bracket of electrical power, and determine by linear programming in the power bracket to meet the P of the object function1,GenAnd P2,Gen, Target generated output of first generator unit within preceding 5 hours at current time and first generator unit are obtained current Target generated output in preceding 5 hours at moment.According to the method described above, the power supply control apparatus can also obtain first hair Electric unit and target generated output of second generator unit within the other times cycle at current time.
The target generated output of S203, the power supply control apparatus according to each generator unit within least one cycle The generated output at each generator unit current time is adjusted.
Specifically, the power supply control apparatus determines target generated output of each generator unit within each cycle with working as The difference of preceding moment generated output, and determine that this is each according to the difference of each generator unit within least one cycle The generated output adjustment amount of generator unit, each generator unit is worked as according to the generated output adjustment amount of each generator unit The generated output at preceding moment is adjusted.
