ENERGY SUPPLY SYSTEM

Japanese Patent JP2015089310

A

PROBLEM TO BE SOLVED: To provide an energy supply system capable of optimal operation of a cogeneration device even when weather changes.SOLUTION: Control means derives predicted power load quantity data posterior to a present time on the basis of past power load quantity data on a power load device 11, derives a temporary predicted heat load quantity data posterior to the present time on the basis of the past heat load quantity data on a heat load device 5, and with reference to a power generation quantity of a photovoltaic power generation apparatus PV during a first prescribed period prior to the present time, correlation between influence degrees given to a heat load quantity consumed by the heat load device 5 during a second prescribed period in which an amount of solar radiation is posterior to the present time when the photovoltaic power generation apparatus PV generates the power generation quantity, and the power generation quantity of the photovoltaic power generation apparatus PV, determines the influence degrees, corrects the temporary predicted heat load quantity data by using the influence degrees, and performs predicted load calculating processing to derive the corrected temporary predicted heat load quantity data as predicted heat load quantity data posterior to the present time.
