The present disclosure relates to the technical field of electric power system, in particular, to a method for analyzing a user load in conjunction with time information and a system thereof.

Peak-valley time-of-use electricity prices are generally adopted by an electric power grid company to encourage an enterprise to reasonably arrange time to use electricity, thereby shaving the peak and filling the valley, and improving the efficiency in using electric power resources. The peak-valley time-of-use electricity prices refer to different electricity prices respectively set for multiple periods, such as peak periods, flat periods and valley periods, obtained by diving 24 hours of a day based on the varying load of the electric power grid.

An enterprise may operate in a non-full-time operational mode or in a full-time operational mode, which depends on different work natures. Conventionally, both the enterprises operating in the non-full-time operational mode and the enterprises operating in the full-time operational mode operate merely in accordance with timetables set by themselves. The timetables may include peak load periods, flat load periods or valley load periods. If the enterprises mostly operate in the peak load periods, the electricity costs may be heavy.

In view of the above, a method for analyzing a user load in conjunction with time information and a system thereof are provided in the disclosure, to reduce an electricity cost of an enterprise.

To achieve the above objective, a solution is proposed as follows.

A method for analyzing a user load in conjunction with time information includes:

obtaining operation periods of an 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; where 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
