Abstract:
1. A multiple power supply integration apparatus comprising: a measurement unit that acquires an electric energy output within a unit time and stability indicating how small a change of electric power in the unit time is, from each of a plurality of irregular power supplies, outputs of the plurality of irregular power supplies having irregularity; an optimum allocation search unit that calculates an evaluation value serving as an index indicating the stability of supply of the electric power of the entire plurality of irregular power supplies while changing a use allocation rate of the plurality of irregular power supplies, based on the acquired electric energy and the acquired stability; and an allocation control unit that sets the use allocation rate of the plurality of irregular power supplies to a use allocation rate when an evaluation value satisfying a predetermined condition is calculated, wherein the optimum allocation search unit calculates the electric energy output and stability per unit time of the entire plurality of irregular power supplies using the use allocation rate as a variable, and calculates the evaluation value using an evaluation function defined so that the evaluation value is larger as each of or one of the electric energy output and stability per unit time of the entire plurality of irregular power supplies is larger or higher.
