PROBLEM TO BE SOLVED: To provide an electro-thermal cogeneration system with a power storage device, which enables the improvement of the efficiency of the overall system and the reduction in installed capacity.SOLUTION: In an electro-thermal cogeneration system with a power storage device, a power is supplied by using a power generated by a power generation device, a commercial power, and a power stored in the power storage device together in a time zone where power consumption of a power load is equal to or more than a specific output C1. In a time zone where the power consumption of the power load is less than or equal to a specific output C2, a power is supplied by a commercial power and the commercial power is stored in the power storage device. In the electro-thermal cogeneration system, since the commercial power is stored in the power storage device in a night time zone, the stored commercial power can be utilized in peak hours, thereby reducing a backup power for peak hours.SELECTED DRAWING: Figure 1 |
