A power generation system and a power control device are provided that, even if there are provided a storage battery and a power conditioner as two independent devices, are capable of supplying electric power at least to the power conditioner in a power outage. The power generation system () includes the control device () connected to a second storage battery () so the that power conditioner () is fed with electric power by a power generation device (), a commercial power grid () and a first storage battery ().

Power generation system, power conditioner, power control device, power control method, and power control program

In a power control system, a control device acquires at least one of information about an external environment (result or predicted temperature) of a facility and information on a parameter associated with power consumption (production plan) in an internal environment of the facility and calculates a correlation between these pieces of information and actual consumed power. The control device predicts consumed power of the facility on the basis the correlation that is calculated and information such as predicted temperature and determines an upper limit set value of power supplied from an electrical grid to the facility on the basis of a result of the prediction. The control device supplies power charged in a storage battery to the facility when the consumed power of the facility exceeds the upper limit set value.

Power control system and method, and control device

A power information display device includes: a power information acquisition unit which acquires information relating to a remaining capacity of a storage battery, and information relating to power consumption of devices that use power of the storage battery; and a display unit which displays usable time of the storage battery when a plurality of devices are operating, and usable time when at least one of the plurality of devices has stopped.

A management system for managing measurement information on power consumption in at least one electrical appliance which is associated with at least one meter includes a first storage module configured to store measurement information transmitted from each of the at least one meter associated with the at least one electrical appliance, on power consumption in the at least one electrical appliance, in correspondence with the at least one meter. The management system also includes a second storage module configured to store history information on association between each of the at least one meter and the at least one electrical appliance. An information output module may be configured to output, in response to selection of an electrical appliance, as electric power information on the selected electrical appliance, information on power consumption in the selected electrical appliance brought in correspondence with a time period regardless of a meter associated with the selected electrical appliance, which is based on the measurement information in the first storage module and the history information in the second storage module.

A home theater includes a main unit section and at least one speaker section. The main unit section includes a communication section which receives an AV stream from an AV stream transmission device and via a communication network, a demux section which separates the AV stream into a video stream and an audio stream, a video processing means which processes the video stream so as to generate a video signal, an audio processing section which processes the audio stream so as to generate an audio signal, and an audio acquisition section which acquires an audio stream which includes at least a part of the audio of the AV stream. The communication section transmits the audio stream acquired by the audio acquisition section to the speaker section, via the communication network.
