A power management server includes a receiver configured to receive an adjustment message for adjusting a supply-demand balance of a power system; a management unit configured to manage two or more apparatuses; a controller configured to determine individual adjusted power amounts each adjusted by a respective one of the two or more apparatuses and start timings at each of which a respective one of the two or more apparatuses starts power adjustment so that a total adjusted power amount requested via the adjustment message is adjusted; and a transmitter configured to transmit a control message including an information element specifying the individual adjusted power amounts and the start timings. The controller determines the start timings that are different from each other and each of which is for a respective one of the two or more apparatuses.

A radio relay device includes: an antenna, which transmits and receives a radio signal with respect to a counterpart radio relay device; and a directivity controller, which adjusts directivity of the antenna, wherein the directivity controller determines whether to adjust the directivity of the antenna based on a relation between a propagation characteristic at a time when the radio signal is received from the counterpart radio relay device in an operating period and an absolute value or a relative value serving as a threshold, and when it is determined to adjust the directivity of the antenna, the directivity controller transmits an adjustment start signal to the counterpart radio relay device and adjusts the directivity of the antenna, with interlocking with the counterpart radio relay device.
