PURPOSE: To utilize energy from the standpoint of both the user and supplier of the energy effectively by combining three kinds of power sources, namely, the commercial power supply system, solar power generation and a generator using fuel, and using the power sources. CONSTITUTION: If the power load 15 <= the amount of power generation of a solar power generator 1, the generated power of the solar power generator 1 is supplied, and the surplus power is made to reversely flow to a commercial power source 9. If the power load 15 > the amount of generated power of solar power generator 1 and if thermal load 17 < the amount of the discharged heat recovered from generator 3 when the powers of the solar power generator 1 and a generator using fuel (generator) 3 are supplied to the power load 15, the powers from the solar power generator 1 and the commercial power source 9 are supplied. If power load 15 > the amount of power the solar power generator 1, and thermal load 17 >= the amount of discharged heat recovered from the generator 3 when the powers of the solar power generator 1 and the generator 3 are supplied, the power generated in the generator 3 and the power generated in the solar power generator 1 are supplied to the power load. |
