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 power at a high voltage and distributing at a low voltage to a plurality of users, comprising:

collectively receiving power, at a receiving and distributing part, said power is purchased by a management company based on a purchase contract with an electric power company in consideration of the total amount of necessary power at a high voltage;

determining a maximum current capacity necessary for each of the users;

determining a current to be contracted for each of the users depending on the maximum current capacity;

setting an adjustable current limiter to said determined contract current for each of the users;

distributing said received power by said receiving and distributing part at a low voltage to each of the users;

receiving a request for a necessary current capacity from each of the users;

allocating a current capacity based on the request to each of the users;

changing the contracted current to be distributed to each of the users;

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; and

changing the setting of the current limiter for said user who adds depending on said determined additional current capacity.

2. The method for collectively receiving power at a high voltage and distributing at a low voltage to a plurality of users 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.

3. A collective housing for collectively receiving power at a high voltage and distributing at a low voltage to a plurality of users, comprising:

means for collectively receiving power, said receiving power which is purchased by a management company based on a purchase contract with an electric power company in consideration of the total amount of necessary power at a high voltage;

means for distributing said received power at a low voltage to each of the users;

a server configured to control a distribution status of each of users and determine a contracted current for each of the users on the basis of information on each of the users supplied to the server;

a control device configured to control and display information on power consumed by each of the users;

a current limiter provided to each of the users, the current limiter being set to the determined contracted current and controlled on the basis of information from the server;

a network for connecting said sever to said control device and to each of the user; and

means for determining a user who adds a current capacity by an auction when a total reguested current capacity is larger than a total contracted current to be distributed and changing the setting of the current limiter for said user who adds depending on said determined additional current capacity.

4. The collective housing for collectively receiving power at a high voltage and distributing at a low voltage to a plurality of users according to claim 3, wherein said server is further configured to receive information regarding an excessive current capacity which is not necessary for one user, receive information on another user willing to increase a contracted current, and allocate the excessive current capacity to the another user on the basis of the information received at the server.

5. The collective housing for collectively receiving power at a high voltage and distributing at a low voltage to a plurality of users according to claim 3, wherein said server is conficiured to receive information regarding a maximum current capacity required by each of the users, determine the contracted current of each of the users on the basis of the information;

and distribute the power to each user.
