Operation plan preparation method, operation plan preparation device, and recording medium

An operation plan preparation device comprising:

• a memory;
• and
• a processor coupled to the memory, wherein the processor executes a process including:
• generating a plurality of scenarios representing the possible set of supply and demand power curves that could occur under a given condition;
• first calculating, for every plural scenarios, an optimal operation plan by which the best evaluation value for a scenario in operation of a storage battery is obtained, and recording the evaluation value of the optimal operation plan as a first evaluation value of the scenario;
• second calculating, for every combination of plural operation plan candidates and plural scenarios, a second evaluation value for an operation plan candidate in the case when a scenario occurs in the operation of the storage battery;
• third calculating, for the every operation plan candidates, a difference between the first evaluation value and the second evaluation value relative to each scenario;
• and
• selecting the operation plan of the storage battery from among the plural operation plan candidates based on the difference.

A non-transitory computer-readable recording medium having stored therein a program that causes a computer to execute an operation plan preparation process comprising:

• generating a plurality of scenarios representing the possible set of supply and demand power curves that could occur under a given condition;
• first calculating, for every plural scenarios, an optimal operation plan by which the best evaluation value for a scenario in operation of a storage battery is obtained, and recording the evaluation value of the optimal operation plan as a first evaluation value of the scenario;
• second calculating, for every combination of plural operation plan candidates and plural scenarios, a second evaluation value for an operation plan candidate in the case when a scenario occurs in the operation of the storage battery;
• third calculating, for the every plural operation plan candidates, a difference between the first evaluation value and the second evaluation value on each scenario;
• and
• selecting the operation plan of the storage battery from among the plural operation plan candidates based on the difference.
