The present invention relates to a method to produce power of a cogeneration system for home use, capable of using even heat, generated from the production of electricity, as heating energy, increasing energy efficiency without power transmission loss since production and consumption are performed at the same place, and minimizing the consumption of energy by generating power by using electricity supplied from an electricity supplier in a section using a small amount of monthly graduated power rates but using cogeneration in a section using a large amount of graduated power rates. The method includes a first step (S21) of confirming an electricity price per supply gas and calculating PMOC which is a calculation value of the periodical optimal usage of external power; a step (S22) of determining whether it is the initial power generation of a period or not; a step (S23) of calculating PCOT, which is the total usage from a period for calculating power rates to the present, if it is not the initial power generation at the step (S22); a fourth step (S24) of calculating PDBC which is a calculation value of a daily generation amount; a step (S25) of operating cogeneration, and accumulating the daily generation amount; and a step (S26) of determining whether daily power generation is completed or not. |
