Description

Sever for providing electric fee saving information and method

The present invention relates to an electric bill saving information server and a method for providing saving information. In particular, the present invention relates to an electricity rate reduction information server and a method for providing reduction information to which a time-of-use differential plan (TOU, Time-of-use) is applied.

The present invention is derived from a study conducted as part of the Power IT Project of the Ministry of Knowledge Economy [Task Management No .: R-2005-1-396, Project Name: Customer Development of Customer Integrated Resource Management System for High Value Power Services].

In general, KEPCO divides electricity bills into residential (high / low pressure), general (A / d), industrial (A / d / bottle), educational, agricultural, and other types of electricity. In the remaining cases, a time-of-use (TOU) scheme is applied, which uses the unit price rate, which is differentiated by season and day by day.

For example, the seasonal differential rate unit price corresponding to the general utility power (A) is shown in FIG. 1.

Figure 1 is a table showing the seasonal differential charge unit price corresponding to the general general power (A).

As shown in FIG. 1, in the case of general-purpose electric power (A), the unit price of charge is summer (July-August), spring and autumn (depending on whether the type of power supplied is low pressure, high pressure A, or high pressure B). The rates are different in March-June, September-October) and in winter (November-December).

The reason for the charge price differential is related to the cost of electricity production. In the spring and autumn, when electricity consumption is relatively low during the year, the price of electricity production is low, so the price is relatively low, and in summer, due to the demand for cooling The proliferation of electric power usage increases the cost of electric power production, which is expensive.

In addition, the time-differential rate unit price corresponding to the industrial power is shown in FIG.

Figure 2 is a table showing the differential price per time zone corresponding to the general industrial power.

As shown in FIG. 2, the time-differential rate unit price is relatively high in a time zone when power demand is high (12 o'clock, 14:00-17:00 o'clock) and relatively low in a time zone (0 o'clock-9 o'clock) when power demand is low. .

Such differential tariffs can reduce costs such as new investment costs through improved load rates and utilization rates from the supplier's point of view, and can reduce the burden of electricity bills through the efficient use of facilities in terms of power users. Enable the use.

However, in order to actively use such a differential rate plan, an analysis system for electricity usage patterns and rate information that reduces electricity rates for power users who are subject to differential rate plans by time is required. It is necessary to provide information that can be changed.

However, until now, the development of a system that performs these functions has not been made, and there is an opportunity for power users to reduce the electricity bill. However, due to the lack of a system capable of performing this, the electricity bill is sufficiently reduced. It is not supported.

The technical problem to be achieved by the present invention is to provide an electricity rate reduction information server and a method for providing electricity saving information that provides a user-specific electricity use pattern to minimize electricity rates based on the time-based differential rate system.

According to an aspect of the present invention for achieving the above technical problem, the method for providing the user with information to reduce the electricity bill comprises the steps of verifying whether the user applies the differential rate plan for each time zone, Receiving at least one electrical device that can be changed and time zone information that can change the use of the corresponding electrical device, Receiving power consumption for each time zone for each of the electrical devices, Differential time-based electricity rate information for each time zone, Generating electricity usage pattern information that generates an optimal electricity rate by using one electric device, time zone information that can be changed in use of the corresponding electric device, and power consumption for each time zone; and generating the optimal electric charge The electricity usage pattern information to make electricity usage pattern information Produced by a step of providing to said user.

According to another aspect of the present invention for achieving the above technical problem, the server for providing information for reducing the electricity bill to the user to which the time-differential rate plan is applied is an electrical device that can change the electricity use time, User interface unit for receiving time-changeable time-of-use information and the power consumption of the time zone of the electric device, the time-differential electricity rate information applied to the user, time-changeable time zone information of the electrical device and power usage of the time zone And a pattern generator for generating electricity usage pattern information for generating an optimal electric charge by using the analysis unit for analyzing the analysis result and the analysis result of the analysis unit.
