Abstract

A method for analyzing a user load in conjunction with time information and a system thereof are provided. In the case that an enterprise operates in a non-full-time operational mode, operation periods of the enterprise are adjusted, electricity prices for respective adjusted operation periods are obtained, and the electricity prices are multiplied with electricity consumptions to obtain electricity charges of the enterprise. In the case that the enterprise operates in a full-time operational mode, electricity consumptions in respective hours of the enterprise are adjusted, the electricity consumptions are multiplied with electricity prices for the respective hours to obtain electricity charges of the respective hours of the enterprise, and the electricity charges of the respective hours are accumulated to obtain a total electricity charge of the enterprise.

First claim

The invention claimed is:

1. A method for analyzing a user load in conjunction with time information, comprising:
determining whether an enterprise operates in a non-full-time operational mode or in a full-time operational mode;
obtaining operation periods of the enterprise and corresponding electricity consumptions in the case that the enterprise operates in a non-full-time operational mode, adjusting the operation periods of the enterprise, and obtaining electricity prices for respective adjusted operation periods of the enterprise based on a preset load distribution table and a preset electricity price table, wherein peak load periods, flat load periods and valley load periods of a region in which the enterprise locates are stored in the load distribution table, and electricity prices corresponding to the peak load periods, the flat load periods and the valley load periods are stored in the electricity price table;
obtaining electricity charges of the respective operation periods of the enterprise by multiplying the electricity prices for the respective operation periods and electricity consumptions in the respective operation periods; and
obtaining a total electricity charge of the enterprise by accumulating the electricity charges of the respective operation periods of the enterprise;
and the method comprises:
obtaining and adjusting electricity consumptions in respective hours of the enterprise in the case that the enterprise operates in a full-time operational mode; and obtaining electricity prices for the respective hours of the enterprise based on the load distribution table and the electricity price table;
obtaining electricity charges of the respective hours of the enterprise by multiplying the electricity prices for the respective hours of the enterprise and adjusted electricity consumptions in the respective hours; and
obtaining a total electricity charge of the enterprise by accumulating the electricity charges of the respective hours of the enterprise.

2. The method according to claim 1 , further comprising outputting the total electricity charge of the enterprise.

3. The method according to claim 1 , further comprising:
obtaining an original total electricity charge of the enterprise; and
calculating a difference between the total electricity charge and the original total electricity charge of the enterprise, and a ratio of a saved electricity charge over the original total electricity charge of the enterprise.

4. The method according to claim 3 , further comprising:
outputting the difference between the total electricity charge and the original total electricity charge of the enterprise, and the ratio of the saved electricity charge over the original total electricity charge of the enterprise.

5. A system for analyzing a user load in conjunction with time information, comprising a processor and a memory storing program codes, wherein the processor performs the stored program codes to:
determine whether an enterprise operates in a non-full-time operational mode or in a full-time operational mode;
obtain operation periods of the enterprise and corresponding electricity consumptions in the case that the enterprise operates in the non-full-time operational mode, or obtain electricity consumptions in respective hours of the enterprise in the case that the enterprise operates in the full-time operational mode;
adjust the operation periods of the enterprise and obtain electricity prices for respective adjusted operation periods of the enterprise based on a preset load distribution table and a preset electricity price table, in the case that the enterprise operates in the non-full-time operational mode; or adjust the electricity consumptions in the respective hours of the enterprise and obtain electricity prices for the respective hours of the enterprise based on the load distribution table and the electricity price table, in the case that the enterprise operates in the full-time operational mode; wherein peak load periods, flat load periods and valley load periods of a region in which the enterprise locates are stored in the load distribution table, and electricity prices corresponding to the peak load periods, the flat load periods and the valley load periods are stored in the electricity price table; and
obtain electricity charges of the respective operation periods of the enterprise by multiplying the electricity prices for the respective operation periods and electricity consumptions in the respective operation periods and obtain a total electricity charge of the enterprise by accumulating the electricity charges of the respective operation periods of the enterprise, in the case that the enterprise operates in the non-full-time operational mode; or obtain electricity charges of the respective hours of the enterprise by multiplying the electricity prices for the respective hours of the enterprise and adjusted electricity consumptions in the respective hours and obtain a total electricity charge of the enterprise by accumulating the electricity charges of the respective hours of the enterprise, in the case that the enterprise operates in the full-time operational mode.

6. The system according to claim 5 , wherein the processor further performs the stored program codes to:
obtain an original total electricity charge of the enterprise, and calculate a difference between the total electricity charge and the original total electricity charge of the enterprise and a ratio of a saved electricity charge over the original total electricity charge of the enterprise.

7. The system according to claim 6 , wherein the processor further performs the stored program codes to:
output the total electricity charge of the enterprise, the difference between the total electricity charge and the original total electricity charge of the enterprise, and the ratio of the saved electricity charge over the original total electricity charge of the enterprise.
