Fuel-cell power generation system and control method therefor

Disclosed is a fuel-cell power generation system including a fuel-cell power generator 100. The system comprises a power measurement section 230 for measuring an actual power-consumption value in a household appliance, a power-consumption estimation section 200 for estimating a future power-consumption value over a given time-period after a given time point, in accordance with the actual power-consumption value measured by the power measurement section 230, and a power-generation instruction section 220 for determining the need of startup/stop of the fuel-cell power generator 100 in accordance with the estimated power-consumption value from the power-consumption estimation section 200. The power generation system can estimate power consumption to be varied between homes to efficiently control the power generation so as to achieve a desirable energy saving performance.
