Abstract

A power consumption-demand/supply adjustment apparatus comprises: a monitor for a consumption amount of supplied power and the quality of supplied power; a contract-adjustment means for supporting establishing of contract for a power demand/supply by adjusting power demand conditions of a customer and power supply conditions of a power supplier; and banking means for requesting a charge of the consumption amount of supplied power and the quality of supplied power, and a charge to be paid from an accumulated deposit based on the contract; wherein the banking means requests the charge of supplied power and the charge to be paid from an accumulated deposit based on monitoring information sent from the monitor.

Claims

1. A power consumption-demand/supply adjustment apparatus comprising:

a monitor for monitoring a consumption amount of supplied power and the quality of supplied power;

a contract-adjustment means for supporting establishment of a contract for a power demand/supply by adjusting differences between power demand conditions of a customer and power supply conditions of a power supplier; and

banking means for requesting a charge of said supplied power consumption amount of and the quality, and said charge to be paid from an accumulated deposit based on the contract;

wherein said banking means requests said charge of supplied power and said charge to be paid from an accumulated deposit based on monitoring information sent from said monitor.

2. A power consumption-demand/supply adjustment apparatus according to claim 1, wherein said banking means pays an excess charge from said accumulated deposit to said power supplier if said consumption amount of power exceeds a contracted amount.

3. A power consumption-demand/supply adjustment apparatus according to claim 1, wherein, if said consumption amount of power underruns a contracted amount, the banking means pays a penalty charge corresponding to a difference between said consumption amount of power and said contracted amount.

4. A power consumption-demand/supply adjustment apparatus according to claim 1, wherein if said power supply conditions does not satisfy the conditions agreed in the power demand/supply contract, said banking means request a penal sum based on said contract.

5. A power consumption-demand/supply adjustment apparatus according to claim 1, wherein said contract-adjustment means collects and stores power supply conditions information sent from a plurality of power suppliers and power demand condition information sent from a plurality of customers.

6. A power consumption-demand/supply adjustment apparatus comprising:

charge calculation means for calculating a power charge based on power consumed; and

charge determination means for determining a requested charge based on the quality of supplied power.

7. A power consumption-demand/supply adjustment apparatus comprising:

power consumption means for inputting information power consumption amount;

charge payment means for calculating a payment charge of each customer based on said power consumption amount and said power quality.

8. A method of adjusting power consumption-demand/supply adjustment apparatus comprising the step of:

calculating a payment charge based on said power consumption amount and quality.

9. A method of adjusting power consumption-demand/supply adjustment apparatus comprising the steps of:

comparing a power consumption amount with a contracted amount;

calculate power bill based on said power consumption amount if said power consumption amount does non exceed the contracted amount; and

calculate power bill based on said power consumption amount, and excess power bill based on an excess power consumption amount which has exceeded the contracted amount.

10. A method of adjusting power consumption-demand/supply adjustment apparatus comprising the steps of:

compare information on the quality of supplied power with the demand quality; and

calculate power bill based on said power consumption amount, and penalty power bill based on information on the quality of supplied power if the actual power quality underruns the demand quality.
