Description of the Related Art In recent years, in the field of industry, power consumption has been increased due to an increase in the number of devices and equipment used for improving working environment comfort, automation and labor saving in a production section, and an increase in various information devices in an office section. The use of is growing significantly.
On the other hand, with the development of comfortable living environments such as home electronics, automation, and labor savings in general households, the use of many AV and information devices, lighting facilities, large refrigerators, The use of washing machines, dryers, and air-conditioning equipment has been progressing, and the power consumption in general households has also increased significantly.

いる。In order to respond to the increasing demand for electric power, electric power companies that supply electric power are particularly required to provide full operation of production facilities and cooling facilities at each business site in fine weather in summer, and to provide cooling facilities for ordinary households. At the peak of the so-called electric power demand that is fully operated, the power generation facilities are operated at full capacity to respond to this. As described above, power companies that supply power are required to have large-scale facilities to meet peak demand for power, but there are many restrictions on the location of power plants and environmental issues. There are conditions, and it is no longer possible to meet the increasing power demand by providing facilities for producing power at the peak of the increasing power demand.

In addition to energy saving measures such as the use of electrical equipment with low power consumption, households are also using energy-saving measures such as the use of inexpensive commercial night power. A large-capacity storage battery is used to store the power, and the power stored in the storage battery is used during a relatively expensive daytime power period to reduce the power rate.

電力負荷平準化の一役を担うことができる。The use of such a distributed power storage system to store inexpensive nighttime power in a storage battery and use the stored power at the peak of daytime power demand reduces the power consumption for consumers. Power supply companies that supply electricity do not need to have excessive facilities for peak power demand during the daytime, so the power demand is dispersed between the daytime and nighttime, and the power load is reduced. It can play a role in leveling.

No. 32322). This conventional technique aims to achieve load leveling by discharging storage battery power during a peak power load in the daytime. Since the battery power is used for a load higher than the contract power, there is an advantage that the contract power can be set low.

Electricity usage patterns in general households are more diverse than in offices and the like. For example, when nobody is at home during the day due to going out on weekdays and holidays, or when leaving home for several days on a trip or the like, the time zone during which maximum power is generated and the amount of power vary.
