Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power usage information providing system and a management server which provide information on power usage by grasping the amount of power consumed by a power consumer by time zone.

[0002]

2. Description of the Related Art Conventionally, electric power contracts for general households are determined by the maximum value (current value) of electric power used, and the charge is calculated by multiplying the electric power consumption by a predetermined unit price regardless of the use time. It is often done.

In this case, as shown in FIG. 8, there is a daytime peak type bias in which most of the consumers have a large demand for power during the daytime and a small amount of power at night when the consumers are asleep.

Therefore, the maximum output of the power generation equipment is adjusted to the electric power in the daytime, and at night when the power demand is low, some equipment must be stopped or operated with the output reduced, and the utilization efficiency of the equipment is reduced. Was low.

For this reason, it is possible to improve the utilization efficiency of equipment by setting a power contract menu in which the daytime electricity charge is made higher and the nighttime electricity charge is made cheaper in order to stimulate the nighttime electricity demand. ing.

[0006] Therefore, as shown in FIG. 9, for a nighttime peak type power consumer in which the load curve for power usage is low during the daytime and high during the nighttime, the nighttime charge is a discounted contract menu, and the nighttime power is preferably supplied. By using it, there is an advantage that the electricity charge can be made cheaper than the case of the daytime peak type.

Also, on the power supply side, by providing this contract menu, it is possible to shift the power demand during the daytime to the nighttime and to flatten the load curve, so that the utilization efficiency of the equipment can be improved.

[0008]

However, an electric power meter in a general household only integrates the amount of electric power used and cannot know the load curve as described above. Therefore, what kind of electric power contract menu is appropriate? It was difficult for the consumer (general household) side to know if there was any.

For this reason, even if the power supply side proposes various power contract menus, there is a problem in that an appropriate selection cannot be made by the consumer and efficient operation cannot be achieved.

[0010] Conventionally, therefore, in the case of specifying an appropriate contract menu according to the power usage situation in a general household,
The person in charge of the power supply side goes to the home, installs a measuring device that measures and records the amount of power used for each time zone, and after measuring for about a week, the person in charge collects the measuring device, The usage status of electricity was analyzed based on the measurement results, and the optimal contract menu was identified and reported to the household.

In order to perform such a measurement, it is necessary to install and collect the measuring device, analyze the measurement result, report the contract menu, and take about one month from the application to the specification of the contract menu. , It took a considerable amount of time.

[0012] In view of the above situation, the present invention is suitable for measuring the power usage state of a consumer through a network and providing the usage information such as a power contract menu and advice according to the measurement result. It is an object of the present invention to provide a power usage information providing system capable of promptly providing various usage information and a management server used therefor.

[0013]

The present invention relates to a power utilization information providing system and a management server used therefor, which receives a measurement result from a customer terminal via a network and uses the power based on the measurement result. By extracting the usage information according to the usage pattern from the usage information storage means and transmitting the usage information to the customer terminal, it is possible to reduce the work of installing and collecting the measuring device. It is possible to perform timely measurement, easily grasp the amount of electric power of each customer by time period, and appropriately provide usage information corresponding to this.

In addition, the management server 1 processes the measurement result according to a predetermined algorithm by the function of the usage information extracting means, and obtains the power usage status of the customer (S7).

FIG. 6 shows a procedure for obtaining a trial calculation value of an electric power charge (hereinafter, also referred to as an estimated electric power charge) when the contract menu is changed as the usage status.

First, from the measurement results received in step 6, the average value of the amount of electric power used for each hour is obtained on a monthly basis (S71).

Next, the hourly usage amount for each month obtained in step 71 is multiplied by the unit price of each contract menu, and the power charge for each contract menu is calculated on a monthly basis (S72).

Next, the estimated power charges for each month calculated in step 72 are added up for each contract menu to obtain the estimated power charges on a yearly basis (S73). The contract menu is as shown in the table below.

[Table 1]

Then, the estimated annual electric power charge calculated in step 73 is stored in the utilization information database (S).

For example, regarding the amount of power consumption measured for each time zone, the usage status is obtained such as in what time zone the peak of usage occurs in each day of the week such as each month, weekday, and weekend.

In summer (eg July, August, September) and winter (eg December, January, February), the amount of electricity used per month is significantly increased compared to other months. If
It is determined that electric power is being used significantly for air conditioning, and this is obtained as the usage status.

Further, when the power consumption exceeds a predetermined value over all the time zones, it is determined that the standby power is too much, and this information is obtained as the usage status.

Then, the management server 1 extracts the usage information corresponding to the usage status from the usage information database by the function of the usage information extracting means (S8).

First, in step 7, out of the estimated power charges stored in the usage information database, the contract menu with the lowest price and the charges are extracted. Not limited to the lowest price, all contract menus, a predetermined number (up to 3 etc.) of contract menus, all contract menus that are cheaper than the current situation, etc.
The fees may be extracted respectively.

Further, the load curve of the customer determined in step 7 is extracted. Also, in step 7,
When the usage situation “electricity is being largely used for air conditioning” is requested, advertisement information that introduces nighttime electricity-using DSM equipment such as eco-ice and a heat storage floor heating device is extracted as the corresponding usage information.

Further, the advice for reducing the electricity bill and the advertisement information of the consultant are extracted.
