Abstract

Disclosed embodiments relate to a power monitoring system. In some embodiments, the power monitoring system includes: a sampling device configured to measure patterns of how loads included in the power system consume energy; an electric meter configured to measure a first amount of energy supplied from a transmission system to the power system; a power supply configured to supply power stored therein or generate power to supply it to the power system, and measure a second amount of energy supplied to the power system; an external server configured to receive measurements of the patterns from the sampling device, and obtain a third amount of energy consumed by the loads based on the measurements; and a home server configured to receive the first amount of energy and/or second amount of energy and transmit/receive data to/from the external server.

Claims

1. A power monitoring system comprising:

a sampling device configured to measure consumption patterns of loads included in a power system that consumes energy;

an electric meter configured to measure a first amount of energy supplied from a transmission system to the power system;

a power supply configured to supply power to the power system, and measure a second amount of energy supplied to the power system, wherein the power supply is connected between the transmission system and the sampling device;

an external server configured to receive the consumption patterns measured from the sampling device and obtain a third amount of energy consumed by each of the loads based on the consumption patterns; and

a home server configured to receive at least one of the first amount of energy and the second amount of energy, and transmit and/or receive data to and/or from the external server,

wherein the home server is further configured to;

receive the third amount of energy from the external server; and

calculate the second amount of energy based on the first amount of energy and the third amount of energy when the measured second amount of energy is not available.

2. The power monitoring system of claim 1, wherein the home server subtracts the first amount of energy from the third amount of energy to calculate the second amount of energy.

3. The power monitoring system of claim 1, wherein the home server subtracts the second amount of energy from the third amount of energy to obtain the first amount of energy when the measured first amount of energy is not available.

4. The power monitoring system of claim 1, wherein the home server is further configured to receive the first amount of energy and the second amount of energy, and convert the received first amount of energy and the second amount of energy in the form of an analog signal into a digital signal to transmit to the external server.

5. The power monitoring system of claim 4, wherein the external server calculates the third amount of energy based on the first amount of energy and the second amount of energy received from the home server when the consumption patterns measured from the sampling device is not received.

6. The power monitoring system of claim 1, wherein the power supply comprises an energy management system and/or a power generator.

7. A power monitoring system comprising:

a sampling device configured to measure consumption patterns of loads included in a power system that consumes energy;

an electric meter configured to measure a first amount of energy supplied from a transmission system to the power system;

a power supply configured to supply power to the power system and measure a second amount of energy supplied to the power system, wherein the power supply is connected between the transmission system and the sampling device;

a first external server configured to receive the consumption patterns measured from the sampling device, analyze the received consumption patterns to obtain a third amount of energy consumed by each of the loads and accumulate the obtained third amount of energy to store statistical data;

a home server configured to receive the first amount of energy and/or second amount of energy and transmit the received first amount of energy and/or second amount of energy to a second external server; and

the second external server configured to receive the third amount of energy from the first external server and receive the first amount of energy and/or the second amount of energy from the home server,

wherein the second external server is further configured to;

calculate the second amount of energy based on the first amount of energy and the third amount of energy when the measured second amount of energy is not available; and

transmit a control instruction to control energy consumption to the home server based on at least the received first amount of energy, the second amount of energy, and the third amount of energy,

wherein the home server is further configured to control the energy consumption of the power system based on the received control instruction.

8. The power monitoring system of claim 7, wherein the second external server subtracts the first amount of energy from the third amount of energy to calculate the second amount of energy.

9. The power monitoring system of claim 7, wherein the second external server subtracts the second amount of energy from the third amount of energy to obtain the first amount of energy when the measured first amount of energy is not available.

10. The power monitoring system of claim 7, wherein the home server is further configured to receive the first amount of energy and/or the second amount of energy, and convert the received first amount of energy and/or the second amount of energy in the form of an analog signal into a digital signal to transmit it to the second external server.

11. The power monitoring system of claim 7, wherein the first external server is further configured to receive the first amount of energy and the second amount of energy from the second external server.
