Power generation leveling system and power generation leveling method
View Patent ↗A communication part of a purchased power management device transmits, in response to an instruction from a user, rate information indicating a rate of power that the user wants to purchase to a sales management device. A charging part of the purchased power management device charges the battery at a date and time designated by the sales management device. A power output part of the purchased power management device outputs power stored in the battery during a time period of high electric power demand. A sale destination decision part of the sales management device decides a sale destination of the power generated during a time period of low electric power demand on a basis of the rate indicated by the rate information. A sales date and time information transmission part of the sales management device transmits sales date and time information designating a date and time when power is sold to the sale destination decided by the sale destination decision part.

an information transmission part that transmits purchased electric energy information indicating a result of the measurement by the electric energy measurement part to the sales management device, wherein
the purchased power management device includes
a communication part that, in response to an instruction from a user, transmits rate information indicating a rate of power that the user wants to purchase to the sales management device;
a charging part that charges the battery at a date and time designated by the sales management device; and
a power output part that outputs power stored in the battery during a time period of high electric power demand, wherein
the sales management device includes
a sale destination decision part that decides a sale destination of the power generated during a time period of low electric power demand on a basis of the rate indicated by the rate information;
a sales date and time information transmission part that transmits sales date and time information designating a date and time when power is sold to the sale destination decided b the sale destination decision part; and
a rate calculation part that calculates an amount billed to an installer of the purchased power management device on a basis of electric energy indicated by the purchased electric energy information transmitted by the information transmission part and the rate indicated by the rate information transmitted by the communication part of the purchased power management device.
2. The power generation leveling system according to claim 1 , wherein the information transmission part transmits the purchased electric energy information to the sales management device by PLC.
3. The power generation leveling system according to claim 2 , wherein when power has been stored in the battery, the power output part of the purchased power management device starts output of power stored in the battery during a time period of high electric power demand set by a user beforehand.
4. The power generation leveling system according to claim 1 , wherein when power has been stored in the battery, the power output part of the purchased power management device starts output of power stored in the battery during a time period of high electric power demand set by a user beforehand.
5. A power generation leveling system that utilizes power generated during a time period of low electric power demand, comprising:
a sales management device that decides a sale destination of the power generated during a time period of low electric power demand;
a purchased power management device including a battery storing purchased power;
an electric energy measurement part that measures electric energy stored in the battery by the charging part of the purchased power management device; and
an information transmission part that transmits purchased electric energy information indicating a result of the measurement by the electric energy measurement part to the sales management device, wherein
the purchased power management device includes
a communication part that, in response to an instruction from a user, transmits rate information indicating a rate of power that the user wants to purchase to the sales management device;
a charging part that charges the battery at a date and time designated by the sales management device; and
a power output part that outputs power stored in the battery during a time period of high electric power demand, wherein
the sales management device includes
a sale destination decision part that decides a sale destination of the power generated during a time period of low electric power demand on a basis of the rate indicated by the rate information;
a sales date and time information transmission part that transmits sales date and time information designating a date and time when s power is sold to the sale destination decided b the sale destination decision part;
a public information part that transmits supply date and time information indicating scheduled date and time when power to be sold is supplied in response to a request from a communication terminal connected with the Internet; and
a rate calculation part that calculates an amount billed to an installer of the purchased power management device on a basis of electric energy indicated by the purchased electric energy information transmitted by the information transmission part and the rate indicated by the rate information transmitted by the communication part of the purchased power management device, wherein
the communication s art of the s purchased power management device transmits the rate information to the sales management device in accordance with a user's operation on a basis of the scheduled date and time indicated by the supply date and time information transmitted by the public information s art of the sales management device.
6. The power generation leveling system according to claim 5 , wherein the information transmission part transmits the purchased electric energy information to the sales management device by PLC.
7. The power generation leveling system according to claim 6 , wherein when power has been stored in the battery, the power output part of the purchased power management device starts output of power stored in the battery during a time period of high electric power demand set by a user beforehand.
8. The power generation leveling system according to claim 5 , wherein when power has been stored in the battery, the power output part of the purchased power management device starts output of power stored in the battery during a time period of high electric power demand set by a user beforehand.
