Abstract

The disclosure is related to a method for controlling an electric power consumption amount of a consumer by a server coupled to a smart grid for managing electric power distribution. The method may include receiving signals having information on electric power consumption amounts from a meter of a consumer through a communication network, determining an electric power consumption pattern of the consumer based on the information on electric power consumption amounts, calculating electric power supply amounts for a predetermined time period based on the determined electric power consumption pattern of the consumer, and transmitting a control signal to the meter of the consumer through a communication network for controlling an electric power consumption amount of the consumer based on the calculated electric power supply amounts.

First claim

What is claimed is:

1. A server, coupled to a smart grid, for managing and controlling an amount of electric power consumed by a customer, the server comprising:
a communication circuit receiving information on the amount of electric power consumption from a meter through a communication network and to transmit a control signal to the meter through the communication network for controlling the amount of electric power consumed by the customer; and
a processor determining an electric power consumption pattern of the customer based on the information on the amount of electric power consumed, and calculating an amount of electric power supplied for a predetermined time period based on the determined electric power consumption pattern of the consumer, wherein the calculating the amount of electric power supplied includes:
determining an electric power supply level based on an overall electric power supply state, wherein the determining of the electric power consumption pattern of the customer includes calculating an average amount of electric power consumed at each unit time based on the information on the amount of electric power consumed included in the received information;
generating the electric power consumption pattern by combining the calculated average amount of electric power consumed;
selecting one of predetermined electric power supply coefficients mapped to the determined electric power supply level and multiplying the electric power consumption pattern of the customer with the selected electric power supply coefficient; and
transmitting a control signal to the meter through the communication circuit for controlling the electric power consumption of the customer based on the calculated electric power supplied.

2. The server of claim 1 , wherein the processor:
calculates current values for the predetermined time period based on the calculated amount of electric power supplied; and
generates the control signal including information on the calculated current values.

3. The server of claim 1 , wherein:
the processor extracts the amount of electric power consumed at a predetermined unit time from the received information; and
the server further comprises a memory configured to store the extracted amount of electric power consumed information in connection with identification information of the consumer.

4. The server of claim 1 , wherein:
the communication circuit receives information from at least one of electric power generation stations; meters of customer, and transmission towers;
the processor measures an overall amount of electric power supplied and an overall amount of electric power consumed based on the received information, to compare the measured overall amount of electric power supplied and the measured overall amount of electric power consumed, and to determine the electric power supply level based on the comparison result.

5. The server of claim 1 , wherein:
the communication circuit receives information on a desired electric power consumption level from user equipment of the customer.

6. A method of managing and controlling an amount of electric power consumed by a customer, the method comprising:
receiving, by a server, information on the amount of electric power consumed by the customer from a meter through a communication network;
determining an electric power consumption pattern based on the information of the amount of electric power consumed by the customer, wherein the determining of the electric power consumption pattern of the customer includes calculating an average amount of electric power consumed at each unit time based on the information on the amount of electric power consumed included in the received information, and
generating the electric power consumption pattern by combining the calculated average amount of electric power consumed;
calculating an amount of electric power supplied for a predetermined time period based on the determined electric power consumption pattern, wherein the calculating the amount of electric power supplied includes determining an electric power supply level based on an overall electric power supply state;
selecting one of predetermined electric power supply coefficients mapped to the determined electric power supply level and multiplying the electric power consumption pattern of the customer with the selected electric power supply coefficient; and
transmitting a control signal to the meter through the communication network for controlling the electric power consumption of the customer based on the calculated electric power supplied.

7. The method of claim 6 , wherein the calculating the amount of electric power supplied comprises:
calculating current values for the predetermined time period based on the calculated amount of electric power supplied; and
generating the control signal including information on the calculated current values.

8. The method of claim 7 , comprising:
controlling, by the meter, the amount of electric power consumed at the predetermined time unit based on at least one of the calculated current values, mapped to the predetermined time unit.

9. The method of claim 6 , wherein the receiving information on the amount of electric power consumption from the meter comprises:
measuring, by the meter, the amount of electric power consumed at a regular interval;
generating, by the meter, the information on the measured amount of electric power consumed; and
transmitting, by the meter, the generated information to the server.

10. The method of claim 6 , wherein the receiving information comprises:
extracting the amount of electric power consumed at the predetermined time from the received information; and
storing the extracted amount of electric power consumption information in a memory of the server in connection with identification information of the customer.

11. The method of claim 6 , wherein the determining the electric power supply level comprises:
receiving information from at least one of electric power generation stations, meters of customers, and transmission towers;
measuring an overall amount of electric power supplied and an overall electric power consumed based on the received information;
comparing the measured overall amount of electric power supplied and the measured overall electric power consumed; and
determining the electric power supply level based on the comparison result.

12. The method of claim 6 , wherein the calculating the amount of electric power supplied comprises:
receiving information on a desired electric power consumption level from user equipment of the customer.

13. The method of claim 12 , wherein the receiving the information on the electric power consumption level comprises:
providing a user interface to the user equipment for enabling the customer to enter the desired electric power consumption level.

14. The method of claim 6 , wherein the electric power consumption pattern is a customer baseline load.
