Operation plan creating method, computer product, and operation plan creating apparatus

A non-transitory, computer-readable recording medium stores an operation plan creating program that creates an operation plan of a power generating system having a power generating apparatus configured to generate power according to an environmental condition from an external source, and a storage cell configured to be charged by the power from the power generating apparatus and discharged according to power supply and demand, the creating program causing a computer to execute a process comprising:

• calculating based on a first corrected operation plan and a second corrected operation plan, an assessment value that indicates whether at an action time, the first corrected operation plan has to be corrected into the second corrected operation plan, the first corrected operation plan obtaining a discharge amount optimal when an operation plan related to the discharge amount from the storage cell is corrected at a given periodic correction time, the second corrected operation plan obtaining a discharge amount optimal when an initial operation plan of the storage cell is corrected at the action time different from the periodic correction time, the assessment value being calculated for a plurality of power supply and demand scenarios stored in a storage unit and indicating transitions of the power supply and demand according to the environmental condition from the external source;
• extracting from among the plurality of power supply and demand scenarios and based on the calculated assessment value, an action-requiring scenario requiring the first corrected operation plan to be corrected to the second corrected operation plan at the action time;
• classifying from the extracted action-requiring scenario and based on the initial operation plan for the action-requiring scenario and the second corrected operation plan, a timing-change action scenario that corrects, at the action time, the initial operation plan for the action-requiring scenario;
• generating for the classified timing-change action scenario and based on the environmental condition from the external source, an identification condition that identifies the classified timing-change action scenario;
• correlating and outputting the generated identification condition and the classified timing-change action scenario;
• and
• controlling charging and discharging of the storage cell based on the output identification condition and timing-change action scenario.
