<P>PROBLEM TO BE SOLVED: To provide an electric power supply system which can restrain electric power supply from becoming unstable due to output fluctuations of photovoltaic power generation, etc. <P>SOLUTION: In a district electric power supply system comprised of an electric power system for electric power supply and a complementary power generation apparatus and a power storage apparatus, the complementary power generation apparatus includes a natural energy utilized power generation apparatus A, a waste burned power generation apparatus B and a sludge digestion gas power generation apparatus C, and a control device 10 includes a generated amount of power prediction unit 11 for natural energy based power generation, a waste burned power generation control unit 14, a sludge digestion gas power generation control unit 20 and a power storage apparatus control unit 21. The waste burned power generation control unit 14 controls the waste burned power generation apparatus B on the basis of generated amount of power prediction information involving a long-period fluctuation from the generated amount of power prediction unit 11, while the sludge digestion gas power generation control unit 20 controls the sludge digestion gas power generation apparatus C to complement a mid-period fluctuation and the power storage apparatus control unit 21 controls a power storage apparatus D to complement a short-period fluctuation. <P>COPYRIGHT: (C)2013,JPO&INPIT |
