Energy equipment determination device and energy equipment determination method

An energy equipment determination method of an energy equipment determination device, the energy equipment determination method comprising:

• an initial group determination step configured to determine a plurality of candidates of an equipment condition indicating a type and size of energy equipment, an operation condition serving as an external factor during operation of the energy equipment, and a control condition during the operation of the energy equipment, and set the plurality of candidates as an initial group;
• a Pareto solution group calculation step configured to apply the initial group determined by the initial group determination step to a genetic algorithm, and calculate a Pareto solution group that is a group of a plurality of Pareto solutions when the primary energy consumption and the system cost including the initial cost and the running cost are objective functions;
• and
• a financial index calculation step configured to calculate a financial index of at least one of a net present value after a specific period from introduction and an internal profit rate after the specific period from the introduction when the energy equipment that individually indicates the plurality of Pareto solutions calculated by the Pareto solution group calculation step is introduced.
