<P>PROBLEM TO BE SOLVED: To securely suppress occurrence of tide fluctuation exceeding adjustment capability of a load frequency controller due to fluctuation of output in a power generator using natural energy even if it occurs. <P>SOLUTION: A power supply system 1 includes: a distribution system 100 having a low-order distribution line 101 to which the power generator 5 and a load 6 are connected and a first high-order distribution line 102 to which the low-order distribution line 101 is connected under control via a transformer 51; and the load frequency controller 3 connected to the distribution system 100. A load agent 10 is attached to each load 6, and a master agent 20 for obtaining a current value of the high-order distribution line is installed. The master agent 20 obtains a time change of a high-order distribution line current value, and extracts a prescribed period component. When adjustment capability of the load frequency controller 3 is deviated, a deviation amount is informed to the load agent 10 under the control of the master agent, and the load agent 10 controls power consumption of the load 6. <P>COPYRIGHT: (C)2012,JPO&INPIT |
