Power generation planning apparatus

An apparatus for controlling power output of a plurality of electric generators, the apparatus comprising:

• a communication interface that is communicatively coupled to the electric generator;
• a memory;
• and
• a processor that is communicatively coupled to the memory and the communication interface,
• where in the processor is configured to:
• receive, using the communication interface, measurement data from the power system,
• calculate generation information regarding a demand of electric power and a supply of the electric power in the power system based on the measurement data,
• calculate a first prediction distribution of supply power from electric power information,
• calculate first plurality of scenarios based on the first prediction distribution,
• calculate a second prediction distribution of the supply power and second plurality of scenarios based on the second prediction distribution in a cycle shorter than the first prediction distribution based on electric power information sequentially updated,
• calculate a first generation plan for one or more of the plurality of the electric generators based on the first plurality of scenarios,
• calculate a second generation plan with a time interval shorter than the first generation plan by adjusting a start initiation time and/or a stop initiation time of the one or more of the plurality of electric generators in the first generation plan such that total power generation cost is reduced by using, as inputs, the first generation plan and the second plurality of scenarios, and
• control, using the communication interface, the one or more of the plurality of electric generators according to the second generation plan.
