DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a first embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is a schematic configuration diagram of an energy supply system 1 according to the present embodiment of the present invention. The energy supply system 1 obtains the gas flow rate of each time by both the gas producer and the user by the communication means, purchases surplus gas from the manufacturer by means of storing the gas, and resells it.

As shown in FIG. 1, the energy supply system 1 includes a gas company 2 and a measuring instrument 3 with a communication device.
1, 3-2, 3-3, 3-4, gas storage means (conduit, holder, etc.) 4-1 and 4-2, connection supply requester 5, customer 6 of connection supply requester 5, control center 8, It comprises a gas conduit 9 of the gas company 2, a gas production facility 10, and the like.

The gas company 2 has a gas conduit 9 for transferring produced gas. The connection supply requester 5 has a gas production facility 10 and produces gas. The connection supply requester 5 and the customer 6 are connected by a gas conduit 9 of the gas company 2.
On the gas conduit 9, the measuring devices with communication devices 3-1, 3-2,
3-3, 3-4, valves 7-1 and 7-2, and gas storage means 4-1 and 4-2 are provided. The connection supply requester 5 supplies gas to the customer 6 via the gas conduit 9 of the gas company 2. Before supplying the gas to the customer 6, the connection supply requester 5 signs a connection supply contract with the gas company 2.

The gas company 2 has a measuring device 3 with a communication device.
In steps 2 and 3-3, the gas flow rate of the gas pipe 9 on the connection supply requester 5 side and the gas flow rate of the gas pipe 9 on the customer 6 side are measured.

The control center 8 has a scale 3 with a communication device.
At steps 1 and 3-4, the gas production status of the connection supply requester 5 and the gas usage status of the customer 6 are measured. Scale with communication device 3-
, Measure the gas flow rate, and transmit the measured value to the control center 8 and the gas company 2 by communication means. Gas storage means (conduit, holder, etc.) 4-1 and 4-2 store surplus gas. The valves 7-1 and 7-2 are controlled to open and close by communication means.

Next, the processing procedure of the energy supply system 1 will be described in detail. FIG. 2 is a flowchart illustrating a processing procedure of the energy supply system 1.

As shown in FIG. 2, the control center 8 controls the gas flow rate (accepted gas amount in the agreement) produced by the gas production facility 10 of the connection supply requester 5 and the gas flow rate of the customer 6 (delivered in the agreement). Outgoing gas amount)
From the measuring device 3-4 by the communication means every hour (step 201).

The connection supply requester 5 adjusts the amount of the received gas and the amount of the delivered gas so as to coincide with each hour. Despite this, if the gas flow rate on the connection supply requester 5 side and the customer 6 side fluctuates by 10% or more, the surplus gas is operated by operating the valves 7-1 and 7-2 by the communication means. The gas is stored in the gas storage means 4-1 and 4-2, or is supplemented when the gas is insufficient.

Specifically, the gas flow rate of the connection supply requester 5 (accepted gas amount) × 0.9 (in the case of the Tokyo Gas connection agreement)
> In the case of the gas flow rate (outgoing gas quantity) at the customer 6 (step 202), the control center 8 purchases the surplus gas, operates the valves 7-1 and 7-2 by the communication means, and temporarily stores the gas storage means. 4-1 and 4-2 (parking) (step 203).

In the case where the gas flow rate of the connection supply requester 5 (the amount of gas received) × 1.1 (in the case of the Tokyo Gas connection agreement) <the gas flow rate of the customer 6 (the amount of gas sent out) (step 20).
4), the control center 8 communicates the valves 7-1,
7-2 is operated, and the gas storage means 4-
It temporarily supplements and sells from 1, 4-2 (backup) (step 205). The purchased gas may be sold to another connection supply requester 5.

Next, specific examples of the compensation fee for exceeding the maximum flow rate, the parking fee for surplus gas, and the backup fee for a gas shortage will be described.

For example, an annual contract amount of 10,000,000
m ³ , unit price 10 yen / m ³ , maximum flow rate 3,500 m ³ / h
In the case where the contract is made under the conditions, the compensation fee when the condition of exceeding the maximum flow rate by 5% for 24 hours is calculated as the compensation fee when the contracted maximum flow rate is exceeded = excess flow rate [m ³
/ H] x 950 yen (Tokyo Gas's connection agreement) ...
From equation (1), compensation fee = 3,500 [m ³ /h]×0.05×24 [h] ×
950 [yen / m ³ = 3,990,000 yen].

The parking fee when the delivery gas amount is 1,600 m ³ / h and the reception gas amount is 2,000 m ³ / h for 24 hours is as follows: parking amount = reception gas amount × 0.9−delivery gas amount
Equation (2), parking fee = parking amount × unit price × 0.3 (in the case of Tokyo Gas connection agreements) ... From equation (3), (2,000 [m ³ /h]×0.9-1,600 [m ³ /
h]) × 24 [h] × 10 [yen / m ³ ] × 0.3 = 14.4
It is 40 yen.

The backup fee when the delivery gas amount of 2,000 m ³ / h and the reception gas amount of 1,600 m ³ / h continue for 24 hours is as follows: backup amount = delivery gas amount−reception gas amount × 1.1 ( In the case of Tokyo Gas's connection agreement) formula (4), backup fee = backup amount x unit price x 1.3 (in the case of Tokyo Gas's connection agreement) formula (5): (2,000 [m ³ / h] ] -1,600 [m ³ / h] × 1.
1 (in the case of Tokyo Gas's connection agreement)) x 24 [h] x 10
[Yen / m ³ ] × 1.3 = 74,880 yen.

As shown in these examples, the parking fee and the backup fee for surplus gas are much lower than the compensation fee when the contracted maximum flow rate is exceeded.

As described above, according to the present embodiment, the control center 8 obtains the hourly gas flow rates of both the connection supply requester 5 as the gas manufacturer and the customer 6 as the transfer destination by the communication means, and When the valve fluctuates, the valves 7-1 and 7
-2, the surplus gas is stored or supplemented in the gas storage means 4-1 and 4-2, and the surplus gas is purchased from the manufacturer and resold, whereby the connection supply request as the gas manufacturer is made. The risk of incurring compensation fees for the person 5
The cost of purchasing surplus gas can be reduced.

By mediating as much as possible, it is possible to expand the customers who are the gas supply destinations of the connection supply requester and to reduce the energy costs of the customers. In place of the connection supply requester 5-5, a pure intermediary that does not supply gas may perform the intermediary business.

Next, a third embodiment will be described. FIG. 6 is a schematic configuration diagram of the energy supply system 21 according to the present embodiment. Energy supply system 2
1. In an energy supply network having a plurality of suppliers and a plurality of customers (for example, a gas conduit 31 of a gas company 2), an intermediary determines a purchase request condition presented by a customer and a supply desire presented by a supplier. Mediate the conclusion of the receiving contract between the customer and the supplier according to the conditions.

As shown in FIG. 6, the energy supply system 21 includes an intermediary 22, a plurality of suppliers 25-1, 25-
, 25-n, a plurality of customers 26-1, 26-2,
, 26-m, a gas conduit (energy supply network) 31, a network (Internet) 30, and the like of the gas company 2.

The intermediary 22 has a computer 29, a supplier database 23, a customer database 24, and the like. , 25-n have computers 27-1, 27-2, ..., 27-n, respectively.
, 26-m have computers 28-1, 28-2, ..., 28-m, respectively.

A plurality of suppliers 25-1, 25-2,.
5-n, and a plurality of customers 26-1, 26-2,.
6-m is the gas pipeline (energy supply network) of the gas company 2
31 and the suppliers 25-1, 25-2,..., 25
-N supplies gas to customers 26-1, 26-2, ..., 26-m.

Further, a plurality of suppliers 25-1, 25-2,
..., 25-n, a plurality of customers 26-1, 26-2, ..., 2
The 6-m and the mediator 22 are connected via a network (Internet) 30 and exchange information.

The supplier database 23 stores each supplier 25
Store penalty charges (compensation charges) corresponding to the shift paid to -1, 25-2,..., 25-n. The customer database 24 stores each customer 26-1, 26-2,.
The difference between the contract amount and the actual usage amount for each m and a penalty fee (compensation fee) for the difference are stored.

Next, the processing outline of the energy supply system 21 will be described. The intermediary 22 receives desired conditions such as a desired price and a planned usage amount from the customer 26 (for example, the customer 26-1) via the Internet 30, and manufactures from a plurality of suppliers 25-1, 25-2,. Receive desired supply conditions such as possible quantity and desired selling price.

The broker 22 determines the cheapest supplier 25 based on the desired conditions received from the customer 26 in accordance with the desired supply conditions from the plurality of suppliers 25-1, 25-2,.
(For example, the supplier 25-2) is selected, and the broker 26-1 and the supplier 25-2 mediate a receiving contract. For example, the gas is supplied from the selected supplier 25-2 to the customer 26-1.

If there is a difference between the contracted amount presented at the end of the term and the actual usage amount due to the circumstances of the customer 26, each customer 26 pays a penalty fee (compensation fee) to each supplier 25 based on each contract. ing. The intermediary 22 calculates a penalty fee. The intermediary 22 is the customer 26-1, 2
6-2,... By summing the individual penalty charges for the entire customer 26, the offset of + and the offset of-are offset, and the penalty fee is optimized and minimized as a whole. The excess or deficiency of energy due to the difference between the actual usage amount and the contract amount of the customer 26 is exchanged between the customer 26, the intermediary 22, and the supplier 25.

Next, the processing procedure for optimizing the penalty fee as a whole at the end of the period of the energy supply system 21 will be described in detail. FIG. 7 is a flowchart showing a processing procedure for optimizing the penalty fee as a whole at the end of the period of the energy supply system 21. FIG. 8 shows a shift in the contract between the customer 26-1 and the supplier 25-2. FIG. 9 shows a shift in the contract between the customer 26-2 and the supplier 25-1. FIG. 10 shows customers 26-1, 26-2,
, And the difference between the total contracted amount and the actual used amount of the suppliers 25-1, 25-2,.

As shown in FIG. 7, at the end of the term,
The intermediary 22 is assigned to each of the customers 26-1, 26-2, ..., 26-
, 35-m are calculated (step 501). Prior intermediary, the intermediary 22
Calculates a difference 35 and a penalty 37 between the contracted amount 33 and the actual usage amount 34 generated in the contract between the customer 26 and the supplier 25.

For example, as shown in FIG. 8, when the actual usage amount 34-1 increases from the contracted amount 33-1 in the contract between the customer 26-1 and the supplier 25-2 at the end of the term, a + shift 35- 1 (Z1) is calculated. The computer 29 of the intermediary 22 calculates a penalty 37-1 (X1) corresponding to a shift 35-1 of + Z1 with respect to the customer 26-1.

As shown in FIG. 9, when the actual usage amount 34-2 is smaller than the contracted amount 33-2 in the contract between the customer 26-2 and the supplier 25-1, the -shift 35-2 (Z
2) is calculated. The computer 29 of the intermediary 22 calculates a penalty 37-2 (X2) corresponding to the shift 35-2 of -2 with respect to the customer 26-2.

In this way, the computer 29 stores the individual shift 35 of each customer 26-1, 26-2,..., 26-m.
-1, 35-2, ..., 35-m and penalty 37-
, 37-m are calculated and stored in the customer database 24.

Next, the computer 29 moves a total of 35
(Z) is calculated (step 502). Computer 2
9 sums up the individual shifts 35-1, 35-2,..., 35-m of the customers 26-1, 26-2,. That is, Z = Z1 + Z2 +... + Zm. For example, as shown in FIG. 10, a total minus 35 (Z) of-from the total contracted amount 33 of the entire customer 26 and the actual used amount 34 is obtained.

Next, the computer 29 communicates with the supplier 25-
Customers 26-1, 2 for 1, 25-2, ..., 25-n
6-2,..., 26-m, a penalty 37 (XS) corresponding to the total shift 35 (Z) is calculated and stored in the supplier database 23 (step 503). Here each customer 26
Is Z = Z1 + Z2 +... + Zm.
1 | + | Z2 | +... + | Zm |> = | Z |, and therefore the penalty fee is also X1 + X2 +... + Xm> = XS.

The computer 29 is connected to the customers 26-1 and 26
The individual penalties of -2,..., 26-m are calculated (step 504). Each customer 26-1, 26-2, ..., 26
The final penalties P1, P2,... Pm paid by −m are the individual deviations 35-1, 35 of the customers 26-1, 26-2,. ,..., 35-m, penalties 37-1 (X1), 37-2 (X2),.
m (Xm), and is calculated as follows. P1 = | X1 | / (| X1 | + | X2 | + ... + | Xm |) * XS P2 = | X2 | / (| X1 | + | X2 | + ... + | Xm |) * XS ... Pm = | Xm | / (| X1 | + | X2 | + ... + | Xm |) × XS

As can be seen from the above equation, the penalty of the customer 26 with a deviation of 0 is also 0. Penalty P calculated
, Pm are held in the customer database 24.

The intermediary 22 communicates the result of the calculation to both the customer 26 and the supplier 25 and obtains an approval (step 5).
05). If the consent is not obtained, the contract is not established (step 506). In this case, the penalty is calculated again by the same calculation method except for the unaccepted customer 26 or the supplier 25, with respect to the customer 26 and the supplier 25 who have agreed. The customer 26 or the supplier 25 who does not understand pays the penalty individually.

If the consent is obtained, the broker 22 collects the penalty charges P1, P2,... Pm from the customers 26-1, 26-2,. A penalty fee (XS) is paid to 1, 25-2,..., 25-n (step 508).

It should be noted that, in the processing of these steps 501 to 508,
The intermediary 22, the supplier 25, and the customer 26 are connected to perform data transmission / reception, check of calculation results, and the like.

As described above, according to the present embodiment, the mediator 22 includes the customer 26-1, the supplier 25-2, and the customer 26-2.
In each individual contract of the supplier 25-1 and the like, the total penalty charges incurred are summed up by the entire customer 26, thereby offsetting the shift of + and the shift of-, and calculating the penalty charge as a whole. The results are shown for individual customers 26-1,
A penalty fee proportionally distributed to the difference between the contracted amount 33 and the actual usage amount 34 of 26-2,..., 26-m is collected from the customer 26 and paid to the supplier 25, whereby the penalty fee paid by the customer 26 is reduced. Can be reduced.

The efficiency and the immediacy can be improved by connecting the intermediary 22, the supplier 25, and the customer 26 via the Internet 30 to transmit / receive data, check a calculation result, and the like.

In the above-described embodiment, the gas supply is described. However, the present invention is also applicable to another energy supply such as water, electricity, petroleum, or combined energy such as hot water, warm air, steam, and hydrogen. Can be used.
