Description

  The present invention relates to an operation method and an operation control system of a fuel consumption facility for efficiently operating, for example, a facility that consumes a large amount of fuel used in a district heat supply business, and an energy trading system.

  In recent years, various service businesses related to energy consumption have been proposed. For example, a mechanism has been proposed in which energy consumption is reduced to obtain a price corresponding to the reduced energy as a service fee (see, for example, Patent Document 1).

  In recent years, projects that consume a large amount of fuel, such as district heat supply projects, have been implemented, and it is important to improve the efficiency of expenses for large amounts of fuel consumption. It has become.

  In carrying out such a project that requires a large amount of fuel consumption, a regional heat supply company, which is a large consumer, concludes a fuel supply contract with the fuel supply company. This contract is usually renewed annually, and the unit price of fuel is negotiated by forecasting annual demand. Usually, the higher the annual demand contract amount, the cheaper the fuel unit price. However, if the actual contracted demand is not achieved, a penalty must be paid to the fuel supplier.

  For example, in the case of a district heat supplier, the fuel consumption is greatly influenced by the weather, particularly the temperature. That is, if a cold summer or warm winter occurs, the fuel consumption may not reach the initial demand, and may be lower than the planned annual amount. In this case, a penalty corresponding to the amount below that is taken, so the unit price of fuel will rise from the initial plan due to a decrease in sales, and the profit will be pressed, and in some cases it may fall below the breakeven point.

  In such cases, weather derivatives have been used as risk hedges, or penalties for fuel consumption shortages have been avoided by signing fuel supply contracts that are less than the planned annual amount.

However, signing a fuel supply contract that is less than the planned annual amount means purchasing a high unit price of fuel, and even if the penalty can be avoided, the economic effect is small.
Japanese Patent Laid-Open No. 2001-155503

  Thus, when renewing a contract with a fuel supplier, in order to reduce the unit price of the fuel, if a contract is made with the annual consumption amount conspicuously, a penalty is imposed if the actual fuel consumption does not reach the contract amount. In addition, if the contract is made with a small amount of annual consumption to avoid this penalty, the fuel unit price itself becomes high.

  An object of the present invention is to provide a fuel consumption facility operation method and operation control system, and an energy trading system that can reliably avoid a penalty at a low fuel unit price.

If it is large, the operation amount of the power generation facility may be decreased, and if it is small, the operation amount of the power generation facility may be increased.

  Furthermore, in the operation method of the fuel consumption facility according to the present invention, the operation of the power generation facility is performed during the peak time of power consumption.

  In the operation control system according to the present invention, a planned fuel supply amount for a certain period for a fuel consumption facility is preset, and a planned fuel consumption value for each unit period is preset in order to achieve the planned fuel supply amount for the certain period.

As a result, a large amount of contracts can be set to reduce the unit price of fuel, while avoiding penalties due to unsatisfactory consumption, and also to use generated power for power transactions with power companies. An effect can be obtained.

  Hereinafter, the best mode for carrying out the present invention will be described in detail with reference to the drawings. FIG. 1 shows the outline of the fuel consuming equipment targeted by the present invention and the relationship between the control signals.

  In FIG. 1, reference numeral 11 denotes a fuel consuming facility, which is owned by a consumer such as a district heat supply company, and includes a power generation facility 12 and a fuel consuming device 13 other than the power generation facility. The fuel consuming device 13 other than the power generation facility is, for example, a heat source device used in a district heat supply business (hereinafter, described as a heat source device), and is connected from the fuel supply source 14 of the fuel supplier to the fuel integrated flow meter 15. Then, a fuel, for example, city gas (hereinafter simply referred to as gas) is supplied, and heat is generated by consuming this gas, and the heat is supplied to the area by a supply system (not shown).

  The power generation facility 12 also receives supply of gas as fuel from the fuel supply source 14 via the fuel integrated flow meters 15 and 16, generates electric power by consuming this gas, and passes through the integrated power meter 17. Thereafter, electric power is supplied to the in-house load 19 and the heat source device 13 through the in-house power line 18. As this power generation facility 12, since the fuel is city gas, a power generator driven by a gas engine or a gas turbine, a fuel cell, or the like can be used. Usually, when the power generation amount is relatively small, a power generation facility driven by a gas engine is often used in terms of efficiency and cost.

  Further, the power line 18 in the station is also connected to the power system 22 of the electric power company through an integrating wattmeter 21.

  The integrated flow meter 15 measures the total fuel supply amount (also fuel consumption amount) to the power generation facility 12 and the heat source device 13. The other fuel integrated flow meter 16 measures the fuel consumption of the power generation facility 12. The integrated watt-hour meter 17 measures the amount of power supplied from the power generation facility 12 to the load side including the on-site load 19. The other integrated watt-hour meter 21 is the amount of power received by the fuel consuming equipment 11 from the power system 22, that is, the power purchased by the consumer having the fuel consuming equipment 11 from the power company having the power system 22. Measure the amount.

  The operation control means 23 has a data recording device 23S, and inputs and records the measured values of the fuel integrated flow meters 15, 16 and the integrated watt hour meters 17, 21 and performs a predetermined calculation described later to generate power. The operation of the entire fuel consumption facility 11 including the facility 12 is controlled. In the figure, a thick line indicates a power line, an arrow thin line indicates a fuel flow, and an arrow broken line indicates a signal flow.

  Here, the consumer having the fuel consuming facility 11 concludes a fuel supply contract with the fuel operator having the fuel supply source 14. This contract is a preset fuel supply amount plan value for a certain period of time for the fuel consuming equipment 11 (for example, one year: the following is assumed as one year). In this case, if the annual fuel supply amount is large, the contracted fuel unit price becomes low. Instead, when the amount of fuel consumed by the fuel consuming equipment 11 falls below the contracted amount of fuel supply, a penalty corresponding to the percentage of the annual performance fee is imposed. In addition, it is usual that conditions such as the maximum contract usage and the monthly usage are included. Therefore, the operation control means 23 controls the operation of the entire fuel consuming equipment 11 so as to satisfy such contract conditions and achieve the contracted fuel supply amount planned value so as not to incur a penalty.

  In this case, the amount of operation of the heat source device 13 depends on the weather, particularly the temperature, and therefore may not reach the initial target depending on the weather conditions (cold summer, warm winter, etc.) of the year. Therefore, the power generation facility 12 is operated with the fuel that is different from the target, and control is performed so as to achieve the annual contract amount while satisfying the various contract conditions described above, thereby preventing a penalty. In addition, the power generated by the power generation facility 12 is utilized to be reflected in the power transaction fee with the power company.

  A specific configuration of the operation control means 23 that performs such control will be described with reference to FIG.

  In FIG. 2, 24 is a database, and in order to achieve the planned fuel supply amount for one year determined by the above-mentioned contract, the planned fuel consumption value for each unit period (in the example shown in the figure) is preset. ing. For each unit period (one day), the calculation means 25 calculates the fuel consumption plan value for the day set in the database 24 and the measured value (the power generation facility 12 and the heat source device 13) of the total fuel integrated flow meter 15 shown in FIG. (Total consumption actual value) of 15m. The calculation means 26 obtains the fuel consumption plan value for the next unit period (next day), and the fuel consumption plan value for the next day is added to the difference from the actual value of the current day by the calculation means 27, and the next day This is the target value for fuel consumption.

  13f is a predicted fuel consumption value for the next day of the heat source device 13. This predicted value 13f is input to the calculation means 28, and a difference from the above-mentioned planned fuel consumption value for the next day is obtained. The obtained difference becomes a fuel consumption target value (operation target value) for the power generation facility 12 on the next day.

  For the difference, a value of 0 or more is selected and output by the high value selection means 29. That is, the fuel consumption target value for the power generation facility 12 is output only when the calculation result by the calculation means 28 is positive. When the calculation result by the calculation means 28 is negative (when the predicted fuel consumption value 13f of the heat source device 13 is larger), the operation of the power generation facility 12 is not performed.

  The target fuel consumption value of the power generation facility 12 obtained in this way is divided by the preset rated fuel consumption amount 12r of the power generation facility 12 by the dividing means 30. The result of division by the division means 30 is the operating time 12t of the power generation facility 12.

  In the above configuration, the power generation facility 12 consumes fuel from the fuel supply source 14 to generate power and supply power to the power line 18. A fuel consuming device other than the power generation facility 12, that is, the heat source device 13, consumes fuel and electric power to produce cold water for air conditioning, hot water, and the like. The on-site load 19 consumes power. The total fuel integrated flow meter 15, the power generation facility fuel integrated flow meter 16, the power generation facility integrated wattmeter 17, and the integrated power purchase wattmeter 21 from the electric power company respectively send measured value signals to the data recording device 23S of the operation control means 23. Send to. The data recording device 23S records each transmitted signal value.

  Here, the operation control means 23 performs a predetermined calculation based on the data recorded in the data recording device 23S at a certain point in time of the unit period (for example, at the end of one day of operation), and the value of the total fuel integrated flow meter 15 However, an operation plan for the next unit period (for example, the next day) is made so as to coincide with the annual fuel consumption plan value set in the database 24.

  The data recording device 23S may be integrated with a monitoring / control device (not shown) of the power generation facility 12 or the fuel consumption facility 11.

  FIG. 2 shows the flow of calculation processing for the operation plan.

In FIG. 2, the calculation means 25 calculates the difference between the planned consumption value of the annual fuel consumption plan value set in the database 24 and the actual value (total fuel integrated flow rate value) 15 m. The consumption plan value for the next day obtained by the calculation means 26 is added to this difference by the calculation means 27, and the result is regarded as the fuel consumption target value for the next day.

  Next, the fuel consumption amount 13f of the next day in the fuel consuming device (heat source device) 13 other than the power generation facility 12 is predicted, and the difference from the fuel consumption target value of the next day calculated by the calculation means 28 is obtained. Is the fuel consumption target value of the power generation facility 12. The high value selection means 29 does not start the power generation equipment when the fuel consumption target value of the power generation equipment 12 is negative (the power generation equipment consumption target value is 0), and when it is positive, it is output to the division means 30. The dividing unit 30 divides the power generation facility fuel consumption target value output from the high value selection unit 29 by the power generation facility rated fuel consumption 12r, and outputs the result as the power generation facility operating time 12t. The operation control means 23 determines the start / stop time of the power generation equipment 12 based on the operation time 12t. The operation of the power generation facility 12 is set to start / stop time so as to be performed during peak hours of power consumption.

  In this way, for each unit period (1 day), the difference between the actual value and the planned value is obtained, the consumption planned value for the next day is added to this difference, and the demand forecast value other than the power generation facility is taken into account. Since the target value of 12 operating amounts (fuel consumption) is determined, the total fuel consumption of the entire fuel consuming equipment 11 becomes equal to or greater than the annual fuel supply amount target value, and no penalty is imposed.

  When the power load falls below the rated output of the power generation facility 12 during the next day's operation and the power generation amount of the power generation facility 12 decreases, the operation time is extended in consideration of the decrease in fuel consumption caused by the power load. Further, during the next day operation, when the total fuel consumption per hour exceeds the amount specified in the contract, the operation may be performed such that the output of the power generation facility is reduced and the operation time is extended.

  Further, the predicted value 13f of the fuel consumption amount for the next day in the fuel consuming device 13 other than the power generation facility is obtained as follows. For example, from the fuel consumption of the day calculated from the difference between the readings of the total fuel integrated flow meter 15 at the start and end of the day, the power generation facility fuel consumption of the day (the power generation facility fuel integrated flow meter 16 at the start of the day And the actual value of fuel consumption of the fuel consuming device 13 other than the power generation facility on that day is directly used as the predicted value 13f of the next day. Alternatively, the moving average value of the past one week of this value (actual value of the day) is set as the predicted value 13f of the next day. Furthermore, the output value of a known prediction model constructed by mathematical means such as a neural network or a regression model is used as the prediction value for the next day. Any of these may be used.

  The arithmetic processing may be automatically performed using a monitoring / control device or a personal computer.

  Also, when the estimated value of the next day's fuel consumption is not used, and the total fuel flow rate is subtracted from the planned consumption value of the annual fuel consumption plan up to the present time, this value is used as the generator fuel for the next day. It is good also as a consumption amount.

  Further, when the difference between the total fuel integrated flow value at each time and the total fuel integrated plan value at each time is positive, this difference may be used as the scheduled generator fuel consumption amount for the next hour. This flow rate is limited to the generator rated flow rate.

  By any of the above methods, the fuel consumption facility 11 can be controlled to achieve the annual planned value.

  In the above embodiment, as shown in FIG. 1, the total fuel consumption of the entire fuel consuming equipment 11 and the fuel consumption of the power generation equipment 12 are measured by the fuel integrated flow meters 15 and 16, respectively. As described above, the measuring devices 35 and 36 may be provided individually as fuel consumption measuring means for the power generation facility 12 of the fuel consuming facility 11 and the heat source device 13 which is another fuel consuming device. Also in this case, the fuel (referred to as gas) is supplied from the supply source 34 to the power generation facility 12 and the heat source device 13 via the corresponding consumption measuring devices 35 and 36, respectively.

  In the database 44, a planned fuel supply amount for a certain period (one year) for the fuel consuming equipment 11 is preset, and a unit period (one day) is used to achieve the planned fuel supply amount for the certain period. ) The fuel consumption plan value for each is preset. The operation control unit 43 operates the gas power generation facility 12 so that the total consumption actual value of the entire fuel consumption facility 11 in the year is equal to or more than the annual supply plan value contracted with the gas supply company. Adjust the control.

  The adjustment method by the operation control means 43 will be described with reference to the flowchart of FIG.

The operation control means 43 shown in FIG. 3 includes, from the consumption measuring devices 35 and 36 and the database 44, as shown in FIG. 4, the gas consumption 35 m of the power generation facility, the gas consumption 36 m of the heat source device 13 and the planned gas. A consumption amount 44p is input. For the gas consumption 36m and the planned gas consumption 44p of the heat source device, the cumulative consumption for one day on the day is obtained (steps 401 and 402). Then, these values are set as the previous day's cumulative consumption A and the previous day's planned cumulative consumption B when performing the next day's operation (steps 403 and 404).

  And the magnitude relationship of these A and B is compared (step 405), and as a result, if the consumption performance value A is more than the consumption plan value B (A> = B), it is not necessary to operate the gas power generation equipment 12. No processing is performed (step 406). On the other hand, when the actual consumption value A is less than the planned consumption value B, the difference C is obtained, and this C = B−A is set as the consumption target value when operating the gas power generation facility 12 (step 407). ).

  On the other hand, since the accumulated gas consumption D on the day of the gas power generation facility 12 is obtained every day (step 408), when the gas power generation facility 12 is operated, the accumulated gas consumption D on that day is obtained on the previous day. A comparison is made as to whether or not the consumption target value C is equal to or greater than that (step 409), and the operation of the gas power generation facility 12 is stopped when D ≧ C. Also in this case, the operation time of the power generation facility 12 is set to be at the power peak time.

  That is, the operation control means 43 compares the fuel consumption planned value B with the actual consumption value A of the fuel consuming device (heat source device) 13 other than the power generation equipment for each unit period (1 day), Accordingly, the operation amount of the power generation facility 12 in the next unit period (next day) is determined. By adjusting the power generation equipment 12 in this way, the actual fuel consumption actual value of the fuel consumption equipment 11 as a whole is maintained at or above the contracted fuel supply plan value, and a penalty is imposed below the fuel supply plan value. Can be surely prevented.

  Further, as shown in FIG. 5, when the gas consumption of the gas power generation facility on the day is α, the gas consumption of the heat source device 13 is β, and the planned gas consumption is γ, the total gas consumption actual value α + β is planned. The gas consumption γ is compared at regular intervals (step 501). As a result, if the total gas consumption actual value α + β is smaller than the planned gas consumption γ, the generator output of the gas power generation facility 12 is increased (step 502), and the total gas consumption actual value α + β is larger than the planned gas consumption γ. If so, the generator output of the gas power generation facility 12 is decreased (step 503).

  That is, the operation control means 43 compares the fuel consumption plan value γ with the total consumption actual value α + β of the power generation facility 12 and the fuel consumption device (heat source device) 13 other than the power generation facility for each unit period (one day). If the total consumption actual value α + β is larger than the fuel consumption plan value γ, the operation amount of the power generation facility 12 is decreased, and if it is smaller, the operation amount of the power generation facility 12 is increased. By adjusting the power generation equipment 12 in this way, the actual fuel consumption actual value of the fuel consumption equipment 11 as a whole is controlled to be approximately equal to the contracted fuel supply plan value, and the penalty is below the fuel supply plan value. Can be reliably prevented from being imposed.

  FIG. 6 shows a charging relationship based on an energy transaction between a service provider who implements the above annual fuel consumption adjustment method and adjustment system, a consumer who receives the service, and a provider who provides fuel and power to this consumer. ing.

  In the figure, 61 is a service provider, 62 is a customer who receives service, 63 is a power company, and 64 is a fuel company. The consumer 62 purchases the electric power 65 from the electric power company 63 and pays the electric power fee 66 to the electric power company 63. Further, the customer 62 purchases fuel 67 from the fuel company 64 and pays the fuel fee 68 to the fuel company 64. Further, the customer receives a service 69 such as operation control (including power if the power generation facility 12 is owned by the service provider 61) from the service provider 31, and pays the service fee 70 to the service provider 61. .

According to this,
Annual fuel consumption of power generation facility 12 a
Annual fuel consumption at the fuel consuming device 13 other than the power generation equipment b
Annual contract fuel trading volume (planned fuel supply amount) c ≒ a + b
Annual power consumption d
Annual power generation of power generation facility 12 e
Annual power purchase de
Fuel unit price f
Unit price of electricity g
Basic fuel charge h
Electricity basic charge k
Then, the fuel fee 68 paid by the customer 62 when the service is not received is expressed by the following equation.

Fuel consumption (b × f + h)
Penalty fee (c / b-1) x (b x f + h)
Total fuel charge (c x f + c / b x h)
The total energy cost A including the power charge 66 is obtained from the following equation.

Total energy cost A = (c × f + c / b × h) + (d × g + k)
On the other hand, the fuel charge 68 and the power charge 66 paid by the customer after the service is provided are as follows.

Fuel charge (a + b) x f + h ≒ c x f + h
Electricity rate (d−e) × g + k
The total energy cost B is obtained from the following equation.

以上より、サービス提供者６１は、サービスを提供しなかったときに需要家６２が燃料事業者６４に支払うと推定される、契約に係るペナルティを含む燃料料金６８と、電力事業者６３に支払うと推定される電力料金６６の合計値から、サービス提供後に需要家６２が電力事業者６３と燃料事業者６４に支払った料金の合計値、さらに発電設備１２に係る保守費、人件費、投資回収費を差し引いた額の一定割合をサービス料金として受け取ることができる。 Total energy cost B = (c × f + h) + ((d−e) × g + k)
Therefore, the difference A−B between the energy costs A and B before and after providing the service is obtained from the following equation.

As described above, when the service provider 61 pays the power provider 63 including the fuel charge 68 including the penalty related to the contract, which is estimated that the customer 62 pays the fuel provider 64 when the service is not provided. From the total value of the estimated power charges 66, the total value of the charges paid by the customer 62 to the power company 63 and the fuel company 64 after the service is provided, as well as maintenance costs, personnel costs, and investment recovery costs related to the power generation facility 12. You can receive a certain percentage of the amount minus the service fee.

  As described above, the service provider 61 determines the annual fuel consumption from the amount obtained by subtracting the maintenance cost, personnel cost, and investment recovery cost related to the power generation facility 12 from the reduction amount of the fuel charge 68 and the power charge 66 of the consumer 62. Service charges can be received as compensation for the provision of the quantity adjustment method and the adjustment system.

  In any of the above embodiments, the city gas is exemplified as the fuel. However, a fuel other than the city gas (for example, heavy oil) may of course be used.
