Abstract

A system for monitoring electric energy amount according to one embodiment of the present disclosure includes an electric energy system including one or more loads receiving electric energy through an external electric energy source and a renewable energy generator, a home server for receiving information of a first electric energy amount that is an electric energy amount consumed by the one or more loads, a second electric energy amount that is supplied from the external electric energy source to the electric energy system, and a third electric energy amount that is supplied from the renewable energy generator to the electric energy system, and an electric energy amount monitoring server calculating the second electric energy amount or the third electric energy amount from electric energy consumption of the electric energy system, which is received from the home server, and supply electric energy amount information supplied to the electric energy system.

Claims

1. A system for monitoring an electric energy amount, the system comprising:

an electric energy system including one or more loads to which an external electric energy source and a renewable energy generator supply electric energy;

a home server configured to receive information of a first electric energy amount that is an electric energy amount consumed by the one or more loads from a panel board connecting to the one or more loads, to receive information of a second electric energy amount that is supplied from the external electric energy source to the electric energy system from an external electric energy source meter connecting to the external electric energy source, and to receive information of a third electric energy amount that is supplied from the renewable energy generator to the electric energy system from a renewable energy meter connecting to the renewable energy generator; and

an electric energy amount monitoring server configured to receive the information of the first electric energy amount and at least one of the information of the second electric energy amount and the information of the third electric energy amount from the home server, and to calculate either the information of the second electric energy amount or the information of the third electric energy amount based on consumption electric energy amount information of the electric energy system, corresponding to the information of the first electric energy amount and supply electric energy amount information of the electric energy system corresponding to at least one of the information of the second electric energy amount and the information of the third electric energy amount,

wherein the electric energy amount monitoring server includes a first server and a second server, and

wherein any one of the first server and the second server is configured to receive the information of the first electric energy amount from the home server, and the other of the first server and the second server is configured to receive any one of the information of the second electric energy amount and the information of the third electric energy amount from the home server, to receive the information of the first electric energy amount from the one of the first server and the second server, and to calculate the other of the information of the second electric energy amount and the information of the third electric energy amount based on the information of the first electric energy amount and the one of the information of the second electric energy amount and the information of third electric energy amount.

2. The system of claim 1, wherein the second server calculates the third electric energy amount by subtracting the second electric energy amount from the first electric energy amount.

3. The system of claim 1, wherein the second server calculates the second electric energy amount by subtracting the third electric energy amount from the first electric energy amount.

4. The system of claim 1, wherein the first electric energy amount includes an overall electric energy amount consumed by the one or more loads, and the second server calculates an electric energy amount consumed by each of the one or more loads based on the overall electric energy amount consumed by the one or more loads.
