Power consumption mode guiding device and system

摘要

Power consumption mode guiding devices (30) are provided in a local system (10) wherein the frequency of power at an AC line (11) to which power consumption apparatuses (14) and a power storage apparatus (12) are connected is controlled to a target frequency that is determined in accordance with the amount of power stored in the power storage apparatus. Each of the power consumption mode guiding devices (30) is provided with: a frequency detection unit (31) that detects the actual frequency of power on the AC line (11); an information storage unit (32) wherein a plurality of pieces of guiding information for guiding the mode of usage of the power consumption apparatuses (14) by power consumers (D) to a prescribed mode are stored in advance in association with frequency information obtained from the detection results of the frequency detection unit (31); and a guiding information output unit (34) that reads, from the information storage unit (32), the guiding information associated with the frequency information obtained from the detection results of the frequency detection unit (31) and outputs the read-out guiding information to the power consumers (D).
