A control device for detecting an individual operation of a distributed power source, a device for detecting an individual operation, and a distributed power source are provided to detect an individual operation of a distributed power source based on power fluctuation injected in an electric power system. A periodic fluctuation unit(22a) generates a power fluctuation of an electric power system. A measuring unit(22d) measures a system cycle. A frequency feedback unit(22b) corrects the power fluctuation. If the system cycle measured by the measuring unit is longer than a previous system cycle, the system cycle is increased. If the system cycle measured by the measuring unit is shorter than a previous system cycle, the system is reduced. A change pattern writing unit(22e) writes a change pattern for determining an individual operation of a distributed power source based on deviation between a recent system cycle and a previous system cycle. A determining unit(22f) determines an individual operation based on the change pattern. |
