Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a method, an apparatus, and a system for selling energy to a consumer, and more particularly, to an energy selling method for measuring energy usage of a consumer and providing energy with an appropriate contract and fee. It also relates to a technique related to this. The energy includes water, gas, and electricity.
[0002]
[Prior art]
In conventional energy sales, for example, there is a sales system that realizes a power supply agreement (implemented on October 1, 2000) disclosed by Tokyo Electric Power Co., Inc. if it is electric power. In this sales system, the power receiving range is limited in units of kW or amperes, thereby determining a basic fee, and setting a metered fee based on the accumulated power usage in kWh for one month.
[0003]
For example, in a power sales system based on a high-voltage power contract based on this power supply contract, the maximum demand power used for actual use is measured every 30 minutes. Based on this maximum value, the contract power for one year from the maximum value update month is determined, and the basic charge is determined in consideration of the contract power.
[0004]
Moreover, in the electric power sales system based on the contract of the metered light lamp for many general households, the circuit breaker is installed in the power supply equipment according to contract ampere. When the power used exceeds the contracted power, the circuit breaker is immediately opened to stop the power supply. As a result, it is possible to sell electric power to many general households without measuring the electric power used as needed.
[0005]
Many systems, devices, and methods are known as peripheral systems for electric power sales, mainly for users to avoid exceeding the contracted power (contract amperes). For example, the device described in Japanese Patent Application Laid-Open No. 11-2649 is configured to issue a warning to the user when the ratio of the actual power usage to the contract power exceeds a certain ratio. It is expected that the user can easily avoid power interruption due to excessive contract power. Further, in the system described in Japanese Patent Laid-Open No. 9-84146, when the power used exceeds the contracted power, a process of limiting the power of some electrical devices based on the priority order is performed.
[0006]
Regarding a gas sales system as energy, there is a sales system that realizes a general gas supply agreement (implemented on July 10, 2000) disclosed by Tokyo Gas Co., Ltd. The basic charge was determined by the number of the gas meter (the numerical value in which the maximum flow rate per hour of the gas meter was displayed in cubic meters), and the metered charge was set by the amount of gas used for one month.
[0007]
[Problems to be solved by the invention]
However, these energy sales systems are not convenient for energy users and impose a burden on them. For example, in an electricity sales system, it is possible to detect the excess of the usage value from the maximum contract value, and unilaterally increase the basic charge or stop the energy supply. Is electrically limited. In the device disclosed in Japanese Patent Application Laid-Open No. 11-2649, when the contract amount is actually exceeded, the power supply is stopped by the circuit breaker, and it is impossible to avoid the occurrence of damage due to the stoppage of the electric equipment. Further, the system described in Japanese Patent Laid-Open No. 9-84146 does not provide a truly comfortable usage environment because the use of electrical devices is unilaterally restricted when contract power is exceeded.
[0008]
In addition, there is a problem that the number of man-hours required for partial sales is large for the energy supplier. For example, in general household power sales, when a contract amperage changes, a new breaker must be prepared and the breaker must be physically replaced. Even in gas sales, to change the contract, a new gas meter with a different number must be prepared and the gas meter replaced. Furthermore, even if the contractor has not paid the fee, he / she goes to the point of use and takes measures to physically cut off the supply of electricity and gas. When collecting unpaid charges, you must return to the point of use and resume supply immediately.
[0009]
An object of the present invention is to provide a method, apparatus, and system for reducing the burden on energy users and suppliers and realizing rational energy sales.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an energy sales method, apparatus, and system according to embodiments of the present invention will be described with reference to the drawings.
[0030]
First, the energy sales system according to the first embodiment of the present invention will be described with reference to FIG. In this embodiment, electric power is handled as energy to be sold. This sales system includes an energy sales device 110 installed in an energy usage contractor's house, a central device 130 that performs an energy sales contract process, a distribution network 120 that supplies electric power, and a service line 121 that carries power to the house. The home power line 122 for distributing power to the house.
[0031]
The energy sales apparatus 110 includes a protective circuit breaker 111 that cuts off the power exceeding the upper limit of the in-house power line facility capacity for security purposes, and stores a contract maximum value of power usage determined between the supplier and the power usage contractor. Means 112; a wattmeter 113 for measuring the current power amount; a means 114 for detecting that the current power amount exceeds the contract power maximum value and calculating an excess frequency; and a power supply amount based on the contract maximum value, etc. A limiting device 115 is provided for arbitrarily limiting or blocking. Furthermore, an input unit 117 for inputting a contract maximum value by communication from the central device, a receiving unit 118 for receiving various inputs from the contractor, and a notification device 119 for displaying various information to the contractor are provided. The integrated power meter 113a records the integrated amount of power used. The operation state monitoring device 116 is connected to each component in the energy sales apparatus through a connection line (not shown), monitors and records each operation state and measurement value, and notifies the central device as necessary.
[0032]
The electric power supplied from the lead-in line 121 is supplied to the home via the protective circuit breaker 111 and the limiting device 115.
[0033]
The central device 130 has means 131 for recording the contract maximum value determined for each contractor and communicating and outputting it to the contract maximum value input means of the energy sales apparatus of the contractor. Furthermore, it has a means 132 for calculating a fee based on various information obtained from the operation monitoring device 116 of the energy sales device of the contractor. All information necessary for charge calculation including contract maximum power of each contractor, record of accumulated power consumption, and payment status of past charges is recorded in the database 133 and can be referred to as necessary.
[0034]
Moreover, the energy sales apparatus, the lead-in line, and the in-home power line are installed for each contractor who uses electric power, or are omitted by the number of contractors.
[0035]
The flow of energy sales according to the present embodiment will be described with reference to FIG. In energy sales in this embodiment, a charge is calculated every month.
[0036]
In step 201, the central device checks whether there is any unpaid balance for the previous month, and if there is an unpaid balance, an unpaid penalty is calculated from the balance and the unpaid period.
[0037]
In step 202, the maximum contract value for the current month is calculated from the contract regarding the maximum power exchanged with the contractor and the unpaid penalty in the central unit.
[0038]
In step 203, the contract maximum value is input / output via communication between the central apparatus and the energy sales apparatus of each contractor.
[0039]
In step 204, the maximum contract value for the current month is recorded in the storage unit 112 in the energy sales apparatus.
[0040]
The above steps 201 to 204 are executed on a predetermined reference day every month.
[0041]
In step 205, the excess frequency calculation means of the energy sales apparatus monitors whether or not the hourly power exceeds the contract maximum amount based on the value of the power meter.
[0042]
In step 206, when there is an excess of power usage, the current excess degree is calculated from the magnitude and time of the excess, and cumulatively updated to the excess number up to the previous time point.
[0043]
In step 207, if the excess frequency is equal to or greater than the first predetermined value D1, the excess frequency is displayed on the notification device 119. In particular, when the cumulative excess number is increasing at the present time, it is highlighted.
[0044]
In step 208, when the excess frequency is equal to or greater than the second predetermined value D2, the notification device 119 displays that the fee increase or the energy usage restriction is to be executed.
[0045]
In step 209, it is read from the accepting means 118 whether the contractor wants to limit energy use or increase the fee.
[0046]
Step 210 is executed when a charge increase is selected. Record the increase in charges in the operation monitoring device, and at the same time temporarily increase the maximum contract value.
[0047]
In addition to this embodiment, every time the excess frequency becomes constant, an excess money may be added to clear the excess frequency to zero.
[0048]
Step 211 is executed when power use restriction is selected. The power is cut off by the limiting device.
[0049]
In addition to the present embodiment, in a portable device that can control an electric device connected to a home power line, control may be performed such that the power is equal to or less than the contract power.
[0050]
The above steps 205 to 211 are always executed.
[0051]
In step 212, the operation monitoring device of the energy sales device transmits information on the accumulated electric energy, excess frequency, fee increase record, and contract maximum extraordinary increase for the current month to the central device.
[0052]
In step 213, the central unit calculates the monthly charge of the contractor from the information on the accumulated power amount, the excess frequency, the record of the increase in charge, and the contract maximum extraordinary increase.
[0053]
The above steps 212 and 213 are executed immediately before the next reference date one month after the reference date on which the above steps 201 to 204 are executed.
[0054]
This is the end of the description of the energy sales flow according to the present embodiment.
[0055]
In the present embodiment, the predetermined values D1 and D2 are determined at any time by the central device according to the reserve ratio of the power equipment (average of the actual supply amount with respect to the supplyable amount), and energy is irregularly transmitted by interrupt communication. It is transmitted to the sales device and set inside it.
[0056]
In addition, in order to prevent accidents such as a fire independently of the flow in FIG. 2, when excessive power flows, the protective circuit breaker 111 operates and cuts off the power. The value of power (kW) allowed by the protective circuit breaker 111 is set at the physical limit of the residential power line. Usually, the contract maximum value is sufficiently smaller than the allowable upper limit of the protective circuit breaker 111.
[0057]
Details of fee calculation by energy sales in this embodiment will be described. The charge for the current month consists of a basic charge determined from the contract maximum value (in kW) and a metered charge determined by multiplying the integrated amount of power used in one month (in kWh) by a predetermined unit price. FIG. 5 illustrates the relationship between the contract maximum value and the basic charge. Here, the basic charges when the maximum contract value is 30 kW and 60 kW are y1 and y2 (yen), respectively. While the maximum contract value is 30 kW, the actual maximum value is 60 kW, and the basic charge when the maximum contract value is temporarily 60 kW in step 210 is y3 (yen). A magnitude relationship of “y3> y2” is established. For this reason, the user of electricity comes to aim at the utilization of the electric power within the range of the contract maximum value determined for economic reasons. It is possible to prevent the total amount of electricity that needs to be supplied from increasing unplanned.
[0058]
The representative effects of the above energy sales are shown. For one thing, even if the power exceeds the maximum contract amount in a short time (less than or less than a predetermined time), the power supply is not suddenly cut off, and the contractor can use the electricity without anxiety. The second effect is that the increase in fees accompanying changes in the maximum contract value can be notified to the contractor and agreed. A supply contract that satisfies both the contractor and the supplier can be made. As a third effect, the maximum contract amount can be set from the central device via communication, and the number of construction man-hours associated with the contract change can be reduced. As a fourth effect, even when charges are not collected, by suppressing the contract maximum amount, it is possible to prevent a large amount of electricity bill from being uncollected in the future while guaranteeing a minimum power supply.
[0059]
Next, a second embodiment of the present invention will be described. Here, gas is handled as energy to be sold. FIG. 3 shows an energy sales system according to the present embodiment.
[0060]
As an apparatus related to gas supply, a gas piping network 320, a drawing pipe 321 to a house, and a gas piping 322 in the house are provided. In addition, a protective circuit breaker 311 that blocks outflows of abnormal gases such as gas leaks, a gas flow meter 313, a gas meter 313a that measures the total amount (volume) of gas used, a contract maximum value, and gas depending on the excess frequency of use A restriction device 315 is provided for restricting the flow rate of the gas by a valve. The other devices have the same functions as those in FIG.
[0061]
FIG. 4 shows a flow of energy sales in this embodiment.
The integrated electric energy replaces the gas meter value (volume), and the wattmeter value replaces the gas flow meter value. In particular, in step 411, the limiting device controls the flow rate by the valve up to the contracted maximum amount instead of cutting off the power. Others are the same as the flow of electric energy sales in FIG. In order to prevent an accident due to gas leakage, independently of the flow of FIG. 4, if there is an abnormal gas flow, the protective circuit breaker 311 is activated and the gas supply is stopped.
[0062]
This completes the description of the second embodiment of the present invention.
[0063]
Next, a third embodiment of the present invention will be described.
[0064]
In this embodiment, in the first embodiment, in addition to the transmission of the contract maximum value from the central apparatus to each energy sales apparatus, the energy sales method based on the contract contents negotiated with the user Is input.
[0065]
FIG. 6 shows an energy sales system according to the present embodiment. In contrast to the system shown in FIG. 1, an excess frequency calculation method setting means 601 is added to the energy sales apparatus, and a program distribution means 602 is added to the central apparatus.
[0066]
Here, the excess frequency calculation means 114 is realized as a microcomputer program.
[0067]
Usually, a contract is made with the user that allows the actual power usage to exceed the maximum contract amount, as shown in the first embodiment, or a contract that does not allow the excess. Can be negotiated.
[0068]
In the case of a contract that does not allow excess, if the power measured by the wattmeter 113 exceeds the contract value, the excess frequency calculation means 114 sends a signal to the limiting device 115 to immediately cut off the power. Is done.
[0069]
In the case of a contract that allows an excess, the excess frequency calculation means 114 is programmed to execute the processing from step 205 to step 211 in the flow of FIG.
[0070]
With reference to FIG. 7, the flow of the program change process will be described.
In step 701, the contract method is selected by the user and recorded in the central device database 133.
[0071]
In step 702, based on the contract method recorded in the database, a program to be used as the excess frequency calculation means of the energy sales apparatus in the user's house is transmitted and input from the program distribution means 602 to the excess frequency calculation method setting means 601.
[0072]
In step 703, based on the received program, the excess frequency selection method setting means 601 updates the microcomputer program for realizing the excess frequency calculation means 114.
[0073]
As shown in this embodiment, the energy sales method can always be updated to an appropriate one by rewriting the excess frequency calculation program from the central device in a timely manner. Here, the program is not limited to that shown in the flow of FIG. Based on the contract with the user, an appropriate program executable by the microcomputer can be transmitted and input.
[0074]
The present invention is not limited to the above three embodiments. For example, as a method of inputting the contract maximum value to be output from the central device to an energy sales device such as electric gas, a method other than by wired or wireless communication may be used as in the above embodiment. Specifically, the central device may output a contract maximum value to a medium such as an IC card, a magnetic card, or a print card, and the energy sales apparatus may read each medium. This method makes it possible to sell energy according to the present invention even in an area where communication infrastructure is not established. Further, the contract maximum value output by the central device may be stored in a portable terminal carried by the worker. The worker sets a new contract maximum value from the mobile terminal to the energy sales apparatus. By this method, illegal writing can be prevented and the maximum contract value can be reliably updated.
[0075]
According to the embodiment of the present invention, in the sale of energy such as electricity and gas, supply and sale satisfying both the supplier side and the contractor side with economic rationality, one of which is a significant burden. Can be done without being forced. Moreover, the man-hour required for energy sales can also be suppressed.
