摘要： This power generation planning device, which carries out plan creation or plan adjustment for a power generation plan for a generator and a ship allocation plan for a transport ship for power generation fuel for the generator, is provided with: an adjustment range calculation unit that calculates an adjustable range and adjustment cost for generator management based on a power generation plan, and an adjustable range and adjustment cost for fuel management based on a ship allocation plan; and an imbalance countermeasure amount calculation unit that, under a constraint condition pertaining to the power generation plan and the ship allocation plan, creates a plan or calculates an adjustment amount for generator management and fuel management that optimizes a prescribed indicator within the adjustable ranges of the generator management and the fuel management.

摘要： This power supply and demand planning device includes: an output range calculation unit that calculates the output range of a power generator that satisfies a plurality of restriction conditions; a power generation output range output calculation unit that calculates the power generator output in a single cross section on the basis of the calculated output range calculated; and a past specified cross section output correction unit that calculates a target output in the single cross section when a restriction condition violation occurs in the power generator output in the calculated single cross section calculated, and in order to eliminate a restriction condition violation, corrects the output range and the power generator output in the single cross section and a past cross section further in the past than the single cross section so that the power generator output in the single cross section becomes the target output.
