Description

In the present invention, surplus power is interchanged between a plurality of power producers as much as possible in accordance with economic efficiency, thereby satisfying the power demand of each power producer and, as a result, the power supply cost of the whole power producer. reduction, further relates to a power resource trading systems and power resources trade server which can be reduced or the like of the CO ₂ emissions per unit sales applicant and buyer refers to the transaction information and the like in a time zone basis The present invention relates to the system and the transaction server capable of accommodating surplus power.

  Currently, the power interchange system being implemented among power producers (hereinafter referred to as “electric power companies”) is operated mainly for the economic achievement of the power supply-demand balance. The selling entity determines the selling price in consideration of the cost required to generate the power.

In addition, this power interchange is often performed individually between each power company, and it is impossible to specify which power generation facility generates the interchanged power. For this reason, it has been difficult to find an optimal sales entity in consideration of not only the cost but also the CO ₂ emission amount, and receive power interchange.

Recently, as a measure to reduce CO ₂ emissions, the power has been transferred from the sales entity to the purchasing entity, and the CO ₂ emissions generated when producing (generating) the power that is the subject of accommodation have also been transferred. It is also considered to inclusion of the CO ₂ in CO ₂ emissions purchase principal side.

By the way, since the transmission of electric power involves a transmission loss, the purchased power amount of the purchasing entity is obtained by subtracting the amount of power for the transmission loss from the production power amount of the sales entity. Therefore, if the transmission loss between the power companies is not taken into account in the transaction of surplus power with CO ₂ intensity, the purchaser's CO ₂ emission intensity cannot be calculated correctly, and transactions with large transmission losses and There is a problem that there is no difference in CO ₂ intensity in transactions with small losses. Of course, transactions that take into account power transmission losses can also be made, but power transmission losses differ depending on the power transmission path, and considering online transactions by multiple companies, appropriate and quick grasp of power transmission losses between transactions is required.

Also, in practice, transactions exceeding the power limit are impossible due to restrictions on power transmission facilities between power companies. In current power interchange, measures are taken so as not to exceed the power limit through human intervention. However, even in the case of online surplus power with CO ₂ intensity, the transaction exceeding the power limit is restricted. Is essential.

  Especially for sellers and buyers, the conditions for daily power transactions (various factors for determining transaction prices, etc.) vary depending on the time of day, and what period of the year is the trend of this change? Therefore, it is necessary for the company to present and acquire information related to power transactions in subdivided time zones.

  The present invention relates to power trading in units of time zones such as the amount of power to be purchased by a power company that desires to purchase, considering transmission loss, etc., when surplus power is interchanged between a plurality of power companies online.

The CO ₂ credits to be bought and sold here are reflected in the “CO ₂ selling (10,000 t-CO ₂ )” or “CO ₂ buying (10,000 t-CO ₂ )” column of the transaction support screen 16.

FIG. 13 to FIG. 16 are descriptions for explaining the power resource transaction system in more detail. 13 and 14 are management function diagrams of the E & C transaction market of the power resource transaction management server 11, FIGS. 15 and 16 are functional diagrams of user interfaces of the terminal devices 12A to 12I, and FIG. a management functional diagram of CO ₂ trading market resource transaction management server 11.

First, in B01 of FIG. 15, when the operator inputs the power configuration of the E & C product, in “A01” of FIG. 13, referring to the database 116, “cost per power source, CO ₂ emission coefficient” for each power company A to I. Thus, the power amount, CO ₂ emission basic unit, and cost of the product are calculated. In B02 of FIG. 15, the generated power amount, CO ₂ emission basic unit, and cost for each power source of the E & C product are displayed on the screen.

Next, the selling price is determined in B03 in FIG. 15, the E & C product is put on the market, and in A02 in FIG. 13, the E & C product is registered in “E & C transaction market data”. This “E & C transaction market data” is registered in the database 116. In A03 of FIG. 13, the E & C transaction market screen 15 is updated from the contents of the “E & C transaction market data” and displayed on the E & C transaction market screen 15 (see FIG. 4) of the user interface (USRI) shown in FIGS. On the other hand, the process is passed to A04 in FIG. In A04, the power generation amount for each power source is displayed on the support screen of USRI in FIGS. 15 and 16 with reference to the power amount and CO ₂ emission amount for each power company A to I in the database 116.

In this support screen, referring to the database 116 in A05 of FIG. 13, the current generated power amount and the target demand power are displayed, and each calculated from the generated power amount and the emission factor for each power source in A06. The difference between the CO ₂ emission amount for each electric power company and the target value is also displayed.

In B04 of FIG. 16, the operator determines whether the transaction is an E & C transaction or a CO ₂ credit transaction from the E & C transaction market screen 15, “CO ₂ credit transaction screen”, and “support screen”. In C01 of FIG. 17, the “CO ₂ credit transaction market screen” is appropriately updated from the content of “CO ₂ credit transaction market data” in the database 116. If it is determined in B04 that the transaction is an E & C transaction, the product number of the E & C transaction is selected in B05 in FIG.

When this contract operation is performed, “E & C transaction market data” is updated in A07 of FIG. 14, and “Electric power trading results and CO ₂ emissions” for each power company A to I are updated in A08. . Next, in A09 of FIG. 14, the “E & C transaction screen” and “support screen” of USRI shown in FIG. 15 and FIG. 16 are updated from the contents of “E & C transaction market data” and “Electric power trading results, CO ₂ emissions”. To do.

On the other hand, if it is determined in B04 in FIG. 16 that the transaction is a CO ₂ credit transaction, in B05 in FIG. 16, the trading price of the CO ₂ credit is determined and an order is placed. In C02 of FIG. 17, examine the possibility of CO ₂ credit trading establishment, a contract worth "CO ₂ credit trading market de - data" registered in, in the C03, "CO ₂ credit trading market of database 116 transactions uncommitted minutes Register in "Data". Then, in C04 of FIG. 17, the CO ₂ emission amount for each electric power company is updated, and from the contents of “CO ₂ credit transaction market data” and “power trading performance, CO ₂ emission amount” of C05, FIG. 15 and FIG. The "CO ₂ credit transaction screen" and "support screen" shown in USRI No. 16 are updated.

FIG. 18 shows a process for creating the CO ₂ power trading price distribution display. In FIG. 18, when the display time zone is input from the interface (S201), “E & C transaction market data” is acquired from the database 116 (S202), and the price of the product and the emission factor are input. Next, for each product, points on the graph of horizontal axis = emission coefficient and vertical axis = price are obtained (S203), and these points are displayed in the power trading price distribution with CO ₂ on the support screen (S204), and the contract is made. It is checked whether there is a finished E & C product (S205). If there is no contracted E & C product, the process is terminated. If there is a contracted E & C product, a coefficient of a straight line by least square approximation is determined from the contracted product (S206), and a straight line by least square approximation is determined from this (S207). Then, the straight line is displayed on the power purchase price distribution with CO ₂ on the support screen shown in FIG. 8 (S204).

In this embodiment, when the power generation of the company is increased or decreased, “the power amount and CO ₂ emission data for each company” is updated, and as a result, the support screen is also updated. FIG. 19 is a diagram showing the flow of processing when the power generation is increased or decreased. In FIG. 19, by inputting the power generation increase / decrease amount for each 24 hour period as the power source type (S301), and then inputting the maximum power generation amount and the lower limit power generation amount, the “cost and discharge per power source” of the database 116 is entered. from the coefficient data "," maximum power generation amount ", acquires the" lower limit power generation amount "(S302), from the" power amount for each company, CO ₂ emission data "obtains" power generation current (house) "( S303).

  Then, it is checked whether the power generation amount after the change is within the range of the lower limit and the upper limit power generation (S304). If it is not within the range, the processing is stopped, and if it is within the range, “the current power generation amount (in-house)”, “margin” "Power" is updated (S305). Thereafter, the support screen is updated (S306) and displayed on the support screen (S307).

Table 7 shows the update contents of “Electricity and CO ₂ emission data for each company” when the power generation amount of the power company C from the time zone 1 to the time zone 8 is reduced by 9000 (1,000 kW).

  FIG. 20 shows the input contents before and after in-house power generation increase / decrease, FIG. 21 shows the support screen before in-house power generation increase / decrease, and FIG. 22 shows the support screen after in-house power generation increase / decrease. The terminal data providing unit 117 provides data corresponding to each time zone to the terminal device in units of one hour time zones, and the E & C transaction market can be set for each time zone. In this embodiment, for each season, one day is divided into 24 time zones, and the power demand for each time zone, in-house power generation / power sales for each power type, and maximum for each power type. We are looking for power generation output and amount of electricity purchased (for in-house use and electricity sales).

  As shown in FIG. 23, the power supply / demand amount for each day can be totaled to obtain the seasonal supply / demand amount. In addition, by taking the seasonal total, it is possible to know the supply and demand status of the power company. For example, by specifying a range of 24 time zones in units of one hour with respect to designation of unit price, emission coefficient, and electric energy, for example, a SELL product is created in the procedure shown in FIGS. 24 (A) and (B). be able to.

That is, in FIGS. 24A and 24B,

By the way, the CO ₂ basic unit reduction target and the reduction of the power supply cost should be finally achieved in the total of all time zones. In the present embodiment, the results of in-house power supply operation and power trading in time zones can be automatically calculated gradually to the total of all time zones, and can be displayed as appropriate by selecting the transaction support screen 16.

FIG. 31 shows the flow of transaction counting processing in all time zones. First, when a company number is input (S401), link data is acquired from the database 116, and a transmission line capacity and a current power generation amount are obtained and totaled for all the time zones (S402). Next, the cost / emission coefficient data for each power source is acquired from the database 116, the demand power amount, the maximum power generation amount, and the lower limit power generation amount are obtained and summed for all the time periods (S403). Further, the amount of electric power and CO ₂ emission data for each company is acquired from the database 116, and the current power generation amount, power sale, power purchase, and consignment revenue are obtained and summed up for all the time zones (S404). After that, the support screen data update process is performed (S405) and provided to the interface (display) of the terminal (S406).

  In the present embodiment, since it is divided into 24 time zones and the trading conditions and the real power consumption are calculated for each time zone, the in-house power generation adjustment function becomes complicated. In order to support this, a dispatch function is added in the present embodiment. The dispatch function is a function that can automatically update the in-house power generation configuration so as to satisfy the target coefficient and minimize the cost. In this function, the shadow price calculated during dispatch calculation shown in FIG. 32 is displayed on the support screen.

  First, demand data is read (S501), and the output of the company's nuclear power and hydraulic power is subtracted from the demand to calculate demand for thermal power (S502). The power generation cost is minimized for the objective function, and the constraint conditions (the upper limit of output of each thermal power generation, the minimum power generation amount of each thermal power generation, the target emission coefficient, etc.) are formulated as optimization problems (S503). Calculation is performed by a linear optimization routine using the simplex method (S504), and the output value and shadow price of each thermal power generation are output to a file (S505).

  For example, FIG. 33 shows a dispatch execution screen when the power company G executes only cost minimization without specifying a target coefficient, and FIG. 34 shows a support screen after execution. FIG. 35 shows a dispatch execution screen in which the target coefficient 0.45 is specified, and FIG. 36 shows a support screen after execution. Further, the calculated shadow price is displayed in a portion surrounded by an ellipse in the dispatch execution screens of FIGS.

  Further, in the present embodiment, in order to handle the power generation cost with high accuracy, it is changed to be classified into a fixed cost (equipment depreciation cost) and a variable cost (fuel cost, etc.). The power generation cost is calculated for each power type as follows.

Power generation cost = fixed cost + variable cost unit (yen / kWh) x power generation amount (kWh)
The power generation cost display part in the support screen is shown in FIG.

FIG. 38 shows how to use dispatch.
(1) Enter the penalty or your target coefficient.
(2) Check “Dispatch” and click the Submit button.
(3) If you are concerned about the proportion of power, check “Dispatch” and “Smooth” and click the Submit button.

FIG. 39 shows an example of dispatch including products on the market.
(1) Input information on products on the market. Dispatching that it is possible to procure 5 yen, 0.0 kg CO ₂ / kWh of electric power of 100 thousand kW per hour.
(2) Enter the penalty or your target coefficient.
(3) Click Dispatch and click the Submit button.
(4) If you are concerned about the allocation of power, check “Dispatch” and “Smooth”, and click the Submit button.

  FIG. 40 shows the result of dispatch including products on the market. As shown in the figure, there is a missing portion of 100000 kW per hour at the top of each bar graph, indicating that it is better to purchase the input product and meet the demand. If it is better not to purchase, the missing part will not occur.

FIG. 41 shows a display example of the shadow price (SP).
The shadow price (SP) is calculated when the discharge coefficient target value is inputted and dispatched. The shadow price shows how much more it will take when trying to further reduce 1t-CO ₂ from the current situation. This example shows that an additional cost of 4300 yen is required.

<How to use 1>
If the SP is different between the summer and the intermediate period, it indicates that the reduction costs are not equalized. For example, if the summer is 4300 yen / t-CO ₂ and the intermediate period is 2500 yen / t-CO ₂ , the summer target is relaxed, the intermediate target is tightened, and the SP is adjusted to match. Better.

<How to use 2>
Compare the potential price displayed on the market screen. If the latent price is cheaper, it is better to grab the product and use it as your own resources.

FIG. 42 shows an example when 0.4 kW-CO ₂ / kWh and 7 kWh / kWh of electricity are purchased in accordance with the above procedure.

In the initial state,
CO ₂ emissions: 80 + 40 + 60 = 180 kg-CO ₂
Total cost: 160 + 200 + 400 + 600 = 1360 yen Shadow price: 20 yen / kg-CO ₂
It is.

By purchase
CO ₂ emission amount: 4 + 88 + 40 + 48 = 180 kg-CO ₂
Total cost: 160 + 70 + 220 + 400 + 480 = 1330 yen Shadow price: 20 yen / kg-CO ₂
It becomes. That is, in this example, the total cost can be reduced by purchasing while maintaining the emission amount.

  FIG. 43 shows the relationship between the forward transaction market and the spot transaction market. Here, FIG. 43 shows the flow of transactions in the forward market and the spot market when one year is divided into summer and winter. Based on the discussion on the liberalization of electric power transactions that are currently being conducted, it is possible to virtually handle two markets, forward transactions and spot transactions, so as to be compatible with future forms of electric power transactions.
