Abstract

This invention provides a method for suitably using a method for collectively receiving at a high voltage and distributing at a low voltage in collective housing. In this method for collectively receiving at a high voltage and distributing at a low voltage to a plurality of users, a distribution control part for collectively receiving power and distributing the power at a low voltage includes a server 12 and a control device 131 for controlling information on power consumed by the users. The control device 131 and the server are connected via a network. The server 12 grasps a maximum current capacity necessary for each user, determines a contracted current depending on the grasped maximum current capacity, and distributes power to each user.

Claims

1. A method for collectively receiving at a high voltage and distributing at a low voltage which comprises collectively receiving power at a high voltage and distributing at a low voltage to a plurality of users, grasping a maximum current capacity necessary for each of the users, determining a contracted current for each of the users depending on the maximum current capacity, and distributing power to each of the users.

2. The method for collectively receiving at a high voltage and distributing at a low voltage according to claim 1, wherein

an excessive current capacity which is not necessary for one user is allocated to another user who need the excessive current capacity.

3. The method for collectively receiving at a high voltage and distributing at a low voltage according to claim 1, wherein

each of the users makes a request for his necessary current capacity, a current capacity based on the request is allocated to each of the users, and the contracted current to be distributed to each of the users is changed.

4. The method for collectively receiving at a high voltage and distributing at a low voltage according to claim 1, wherein

each of the users is charged a penalty when a current actually used exceeds the contracted current allocated to each of the users.

5. A method for collectively receiving at a high voltage and distributing at a low voltage which comprises collectively receiving at a high voltage and distributed at a low voltage to a plurality of users, grasping a maximum current capacity necessary for each of the users, determining a contracted current for each of the users depending on the maximum current capacity, and distributing power to each of the users,

further comprises making a request for a necessary current capacity by each of the users, allocating a current capacity based on the request to each of the users, and changing the contracted current to be distributed to each of the users,

and further comprises determining a user who adds a current capacity by an auction when a total requested current capacity is larger than a total contracted current to be distributed.

6. The method for collectively receiving at a high voltage and distributing at a low voltage according to claim 5, wherein

each of the users is charged a penalty when a current actually used exceeds the contracted current allocated to each of the users.

7.
