Description

  The present invention relates to an energy transaction method using a computer for setting a price and delivering a commodity when selling and selling primary energy such as fuel from a seller to a secondary energy producer such as an electric power company.

Primary energy is sold to secondary energy producers who produce secondary energy such as electricity from primary energy sellers that sell primary energy such as petroleum (heavy oil / light oil), coal, gas, etc., producing secondary energy The person uses the secondary energy produced by using the primary energy, for example, in-house, such as in-house, or sells it to other companies like an electric power company.
Prices of primary energy such as oil, coal, and gas are fluctuating, but secondary energy producers tend to desire stable and low price transactions.

JP 2002-63244 A

  Various methods for calculating such secondary energy charges have been proposed. For example, an entity (secondary energy user) that does not have secondary energy production equipment purchases and purchases primary energy in the “energy charge calculation method and energy charge calculation apparatus” disclosed in Japanese Patent Application Laid-Open No. 2002-63244 of Patent Document 1. Produces and produces multiple types of secondary energy such as electricity and heat by processing primary energy such as gas generated using energy production facilities such as cogeneration systems owned by energy suppliers (secondary energy producers) There is a method to reduce costs for an entity by supplying the secondary energy from the energy supplier to the entity and calculating the processing fee required for processing as the secondary energy fee to be paid from the entity to the energy supplier. Proposed.

  However, in order for secondary energy users mentioned above to procure primary energy at a competitive price, they must purchase large quantities of fuel, including uses other than those consumed by secondary energy producers. However, the proposed energy charge calculation method has a problem that only a very limited number of businesses can enjoy the benefits.

  Secondary energy producers are also required to meet the conflicting needs of streamlining fuel storage facilities, reducing logistics costs, and responding to increased fluctuations in fuel consumption.

  If facilities such as power generation of multiple secondary energy producers are adjacent to each other, it is possible to concentrate them on a common fuel storage facility for efficient interoperability. In many cases, there was a problem that the efficiency of transportation and storage of fuel could not be achieved.

  The present invention has been developed to solve the above-described problems. That is, the object of the present invention is to efficiently procure and inventory primary energy for a plurality of secondary energy producers, thereby delivering and replenishing the primary energy and processing the settlement smoothly and safely. The object is to provide a method for trading energy using a computer.

  According to the present invention, a primary energy seller (A) who sells primary energy such as fuel is a secondary energy producer (B, B ′, B ") is an energy transaction method using a computer that buys and sells at a predetermined price, and the primary energy seller (A) is the secondary energy producer (B, B ', B") The upper and lower limit value data on the consumption amount and the secondary energy production amount related to the production facility that produces the secondary energy is made into a database, and the secondary energy producer (B, B ', B ") is the fuel remaining amount, consumption state, consumption The information of the plan is communicated to the primary energy seller (A), and the primary energy seller (A) reports the status of secondary energy production facilities of the secondary energy producers (B, B ′, B ″). Provided a trading method of energy using a computer characterized by comprehensively replenishing primary energy to the secondary energy producers (B, B ', B ") in consideration of data etc. Is done.

  The secondary energy producers (B, B ', B ") transmit information on the remaining fuel amount, consumption status, and consumption plan to the management server (4) of the primary energy seller (A) via the Internet.

  The secondary energy producer (B, B ′, B ″) can pay for the primary energy purchased from the primary energy seller (A) according to the amount of heat generated by the primary energy. , The secondary energy producer (B, B ′, B ″) is actually using the secondary energy producer (B, B ′, B ″) for the primary energy purchased from the primary energy seller (A). You can pay the price according to the amount of power generated.

  The primary energy seller (A) is a person who sells oil having several grades with different oil types such as heavy oil and light oil, kinematic viscosity and sulfur content. The primary energy seller (A) is a person who sells coal having several grades of volatile matter, moisture / viscosity, ash content, sulfur content / nitrogen content / chlorine content, ash melting point, and calorific value. . Alternatively, the primary energy seller (A) is a person who sells gas such as liquefied petroleum gas (LPG) or liquefied natural gas (LNG).

  The primary energy seller (A) is provided with the secondary energy producer (B, B ′) on condition that primary energy is provided as compensation for the secondary energy producer (B, B ′, B ″). , B ") can supply secondary energy such as electric power to the primary energy seller (A).

  The primary energy seller (A) and the secondary energy producer (B, B ', B ") can make payment using an escrow account when paying for the primary energy.

  The secondary energy producer (B, B ′, B ″) sends the fuel storage facility (1) and transportation facility repair costs, which are a risk of fluctuation, to the primary energy seller (A) based on management data. You can pay the price calculated by switching to a fixed charge.

When the amount of primary energy stored in the fuel storage facility (1) installed in the secondary energy producer (B, B ′, B ″) falls below a certain amount, the primary energy seller ( A) replenishes secondary energy producers (B, B ′, B ″) with primary energy.
When replenishing the primary energy, the primary energy within the range that can be used in the facilities of the secondary energy producer (B, B ', B ") with respect to the brand / grade of the primary energy to be replenished. The seller (A) can arbitrarily select.

  In the above method, the primary energy seller (A) can efficiently procure and inventory primary energy such as fuel supplied to a plurality of secondary energy producers (B, B ′, B ″). The primary energy seller (A) collectively handles the management, operation, and replenishment of required fuel in the fuel storage facilities (1) in the production facilities of each secondary energy producer (B, B ', B "). This enables efficient transactions.

For primary energy sellers (A), what has traditionally been required to respond to the designation of the brand, quantity, and time from the customer can be delivered at their own discretion during the entire operation of the company. Can avoid the risk of long-term inventory.
Since the primary energy seller (A) performs inventory management at the secondary energy producer (B, B ', B ") that is the sales destination, depending on the situation, the secondary energy producer (B, B', B) ") Primary energy can be transferred between.
In addition, by applying a price that is commensurate with the amount of heat generated and the amount of power generated, the price does not depend on individual brands, transportation timing, etc., so it is easy to hedge the price risk on the basis of the primary energy seller (A) 's wish.

  The primary energy seller (A) is provided with the secondary energy producer (B, B ′) on condition that primary energy is provided as compensation for the secondary energy producer (B, B ′, B ″). , B ") supplies power to the primary energy seller (A), so that both can reduce the procurement cost in the immediate vicinity. If you settle with an Escrow account, you can quickly and safely collect money.

  In the energy trading method using the computer of the present invention, a primary energy seller who sells primary energy such as fuel is a secondary energy producer B who produces secondary energy such as electric power from the primary energy. This is a method of delivering and selling at a predetermined price using a computer.

Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a block diagram showing an energy trading method using the computer of the present invention.
In the energy trading method of the present invention, as shown in FIG. 1, a primary energy seller A makes a plurality of secondary energy producers B, B ′, B ″ who produce secondary energy such as electric power from primary energy. The secondary energy produced by the secondary energy producers B, B ′, B ″ is used by a secondary energy user C such as a manufacturer. In the illustrated example, three secondary energy producers B, B ′, and B ″ are described, but the number is not limited to this number.

  The primary energy seller A is an oil supply company or a trading company that sells oils having several grades with different oil types such as heavy oil and light oil, kinematic viscosity and sulfur content. The primary energy seller A is a coal supplier that sells coal with several grades of volatile matter, moisture / viscosity, ash, sulfur / nitrogen / chlorine, ash melting point, and calorific value. Trading company. Furthermore, it is a gas supply company or a trading company that sells gas such as liquefied petroleum gas (LPG) or liquefied natural gas (LNG).

  The secondary energy producer B is an electric power company that performs thermal power generation using primary energy such as oil or coal, or a business that has private power generation facilities. Here, the electric power company means a person who sells the electric power generated by his / her own generator to other companies. This power company also includes IPP (wholesale power business) or PPS (power retail). In other cases, the company owns a large-scale private power generation facility and sells surplus electricity for its own use. Conversely, there are small on-site power supplies such as micro gas turbines. An operator having a private power generation facility refers to a company that owns its own power generation facility in its own premises, such as a factory, and uses the power generated there for the operation of the factory. Furthermore, there are cases where a manufacturer or the like implements a cogeneration system that generates power using surplus energy such as heat generated when primary energy is used for manufacturing a product.

  In the present invention, the primary energy seller A comprehensively efficiently procures and inventoryes the primary energy of the plurality of secondary energy producers B, B ′, B ″. The primary energy seller A collectively manages the management, operation, and replenishment of required fuel of the fuel storage facilities 1 in the facilities B, B ′, B ″, so that the efficiency of the transaction can be improved.

FIG. 2 is a block diagram showing an example of a system for implementing the energy trading method.
The energy trading method system according to the present invention includes a measuring device for measuring the remaining amount of oil, coal, gas, etc. in the fuel storage facility 1 installed in the secondary energy producers B, B ′, B ″. The information such as the remaining amount of storage is communicated to the primary energy seller A together with other status information by the processing device 2. This communication means is not limited to the Internet described later, and uses other various communication means. Can do.

  The primary energy seller A inputs each information such as the remaining amount of storage from the processing device 2 provided in the fuel storage facility 1 to each secondary energy producer B, B ′, B ″ via the Internet. The primary energy seller A that receives the information receives the information from the output device 3. The remaining amount of fuel stored in the fuel storage facility 1 of each of the secondary energy producers B, B ', B "is received by the management server 4 and the processing device 5. To manage various information. For example, the secondary energy producer B uses the management server 4 of the primary energy seller A to obtain the consumption data related to the secondary energy production equipment that can be used for secondary energy production and the upper and lower limit value data relating to the production amount of the secondary energy. In the database. These pieces of information are selected as necessary, and input to the management server 4 for management.

  The primary energy seller A delivers primary energy to the secondary energy producer B by comprehensively considering the status and data of the secondary energy production facilities of each secondary energy producer B. , Replenishment is processed at once.

  The primary energy seller A formulates an optimal transportation and release plan of the fuel storage facility 1 based on information on the fuel storage facility 1 of the secondary energy producers B, B ′, B ″. When the remaining amount of primary energy stored in the fuel storage facility 1 installed in the secondary energy producers B, B ′, B ″ is reduced, the primary energy is conveyed and replenished.

  When the amount of primary energy stored in the fuel storage facility 1 installed in the secondary energy producers B, B ', B "falls below a certain amount, the secondary energy producers B, B', B" Transport to. Here, the fixed amount used as the reference | standard at the time of replacing | exchanging the fuel storage equipment 1 is consumption for the predetermined period of about 2 to 3 days and about 3 to 4 days in secondary energy producers B, B ', and B ", for example. Can be a standard.

  When replenishing this primary energy, sell the primary energy as long as it can be used at the facilities of the secondary energy producers B, B ', B "with respect to the brand and grade of the primary energy to be replenished. The person A can select arbitrarily.

FIG. 3 is a block diagram showing the flow of the energy transaction method.
The inventory information of the secondary energy producers b, b ', b "is aggregated via the Internet to the management server 4 of the primary energy seller A. The required quality of the secondary energy producers B, B', B" Originally, the most efficient refueling method is calculated by the management server 4 of the primary energy seller A. At this time, what and how much is transported from the primary energy seller A? Or consider whether to transfer from other secondary energy producers BB ′, B ″.

  From the secondary energy producer B, tighten the fuel consumption status (calorific value base / power generation base) of the secondary energy producers B, B ', B "in a predetermined period such as daily / weekly / monthly. Calculate the price to be paid to the primary energy seller A. The calculation of the price is automatically calculated by the primary energy seller A's server collecting data as the calculation parameters from the secondary energy producer B / secondary energy producer B. Then, both the primary energy seller A and the secondary energy producer B confirm and input it.

  Thus, for example, although the domestic distribution price of coal varies greatly depending on the brand and country of origin, even if it has the same calorific value, it is arbitrarily determined by the primary energy seller A which brand is replenished. Therefore, the secondary energy producer B, B ', B "does not pay the primary brand or quantity A to the primary energy seller A, but according to the amount of heat generated by the fuel or the amount of power actually generated. We will pay the compensation.

  If the secondary energy producer B is a power retailer, the secondary energy producer B and the primary energy seller A sign a power supply contract, and the primary energy seller A It is also possible to provide in-kind fuel as an electricity bill to be paid to B.

  The primary energy seller A and the secondary energy producer B can settle using the escrow account when paying for the primary energy. This escrow account (escrow) is an account that does not have an account name and can temporarily pool deposits, which can be refunded only when certain conditions are met. Say.

  Secondary energy producers B, B ', B "should switch the fixed costs to the primary energy seller A based on the management data for repair costs of the fuel storage facility 1 and transport facilities, which are subject to fluctuation risks. Can be calculated and paid.

Restrictions are imposed on the type of fuel and the boiler. Due to problems such as combustion, storage, and environmental regulations, the following grades are the criteria for determining whether or not to use them.
Oil is mainly used for power generation and other business purposes, including heavy oil and light oil. Heavy oil is further classified into A heavy oil / B heavy oil / C heavy oil according to kinematic viscosity (stickiness). Moreover, the heavy oil actually sold and sold is further classified according to the S content (cause of the sulfur content and sulfur oxide “SOX”). The required quality of the boiler includes oil type (heavy oil, light oil), kinematic viscosity, S content and the like.

For coal, the quality of flammability, compliance with environmental regulations, ease of processing of ash after combustion, etc. are the criteria for determining the availability of each brand. These required quality values vary depending on the manufacturer, size, and attached equipment (existence of desulfurization equipment, etc.) of each boiler.
Regarding the required quality of boilers, volatile matter (related to ease of ignition), moisture / particle size (related to handling, etc.), ash (related to ash generation, etc.), S / N / chlorine, etc. (environmental regulations) ), Melting point of ash (temperature at which ash melts—related to post-treatment of ash, etc.), calorific value (related to combustion temperature, efficiency, etc.), and the like.

  There are two main types of gas: LPG (liquefied petroleum gas) and LNG (liquefied natural gas). The two are not compatible. There are cases where the specific gravity varies depending on the ingredients and cannot be mixed and stored.

  It is also possible to place employees in the fuel logistics facility entrusted by the secondary energy producer B as a location for surplus personnel in the primary energy seller A. For example, an electric power company that itself is a fuel consumer This can also be applied when reselling fuel.

FIG. 4 is an explanatory diagram showing a management database of each information in the energy supply company.
Next, an example of the transaction when the primary energy is coal is shown. At the secondary energy producer B factory (in-house), volatile content: 30 to 35%, ash content: 10 to 15%, and S content: 0.6% or less are required as the required quality. Quantity data includes coal storage, consumption (actual), and consumption (plan).

  In the secondary energy producer B 'factory (in-house), volatile content: 35 to 38%, ash content: 6% or less, and S content: 0.5% or less are required as the required quality. Quantity data includes coal storage, consumption (actual), and consumption (plan).

  Secondary energy producer B "power plant (electric power company) requires volatile content: 25-40%, ash content: 5-20%, S content: 1.0% or less as the required quality (extract). Quantity data includes coal storage, consumption (actual), and consumption (plan).

  The inventory data and the quantity data of secondary energy producers B, B ', B "using coal are collected on the server of the primary energy seller A that sells coal.

As primary energy seller A's inventory data for sales,
Charcoal: 5,000t
(Volatile content 28%, Ash content 15%, S content 0.6%)
Charcoal: 50,000t
(Volatile content 36%, Ash content 7%, S content 0.2%)
+
Charcoal: 60,000t [Transporting from overseas]
(34% volatile matter, 5% ash content, 0.4% S content).

  Next, when primary energy seller A wants to determine "Where is the factory that needs to be replenished early?", For example, secondary energy producers with low coal storage and high daily consumption It is judged that the power plant of B "should be given priority. The server of the primary energy seller A automatically calculates the future coal storage amount transition.

  In addition, when the primary energy seller A wants to determine “What inventory do you want to sell at an early stage?”, For example, to secure a place for the coal scheduled to arrive next week, it is determined that you want to sell out the charcoal quickly. . The server of primary energy seller A automatically calculates future sales inventory transition.

The required quality of each boiler is registered in advance in the server of primary energy seller A, and the delivery pattern to each factory (secondary energy producers B, B ', B ") is automatically formulated based on the future quantity simulation results. To do.
For example, a charcoal 3,000 t + a charcoal 3,000 t → delivered to a secondary energy producer B "power plant. In this case, if blended 5: 5, the volatile content is 32%, the ash content is 11%, the S content is 0.00. It will be around 4%, and both shall be within the required quality.
A charcoal 2,000t + lignite 1,000t → Delivered to the factory of secondary energy producer B. In this case, if blended at 2: 1, the volatile content is 31%, the ash content is 12%, and the S content is about 0.5%, and all are within the required quality.
The U coal arrives after the a coal yard has been emptied, and the secondary energy producer B's factory has plenty of room for coal storage. Deliver u charcoal after arrival.
The quality after blending is basically a proportional calculation according to the ratio, but analysis data from secondary energy producers B, B ', B "is fed back as appropriate to improve the accuracy of blend quality simulation.

  Consumption data (power generation amount or heat generation amount <unit heat generation amount x consumption amount>) at the secondary energy producer B, B ', B "is sent to the server of the primary energy seller A, and the unit price determined in advance by the contract Multiply to calculate the amount billed and complete the payment procedure.

  In the example described above, a method in which an electric power company mainly replenishes coal and oil at an optimal time and settles the settlement has been described in detail. However, the present invention is not limited to such an embodiment, and the present invention Various modifications can be made without departing from the scope of the present invention.

  In the energy trading method using the computer of the present invention, it has been necessary for the primary energy seller to respond to the designation of the brand, quantity and time from the customer. Since it can be delivered at its own discretion, it is possible to avoid risks such as long-term inventory of specific brands.

  When applying a price that is commensurate with the amount of heat generated or the amount of power generated, the price is not affected by individual brands and transportation time, etc., so price risk hedging is facilitated based on the company's wishes.

  When a power supply contract is made between a secondary energy producer and a primary energy seller and the electricity bill is settled with the actual fuel, both can reduce the procurement cost in the immediate vicinity. If small and medium-sized enterprises purchase fuel with the spread of on-site power supply, the risk of non-collection of money will increase. However, if payment is made with an escrow account, the money can be collected quickly and safely.

  The transaction method of the present invention can be applied from the standpoint of either a buyer or a seller of fuel. Also, the fuel type can be applied to any fuel type such as petroleum, gas, and coal.
