Description

  The present invention relates to a plan determination device and a plan determination program.

With the recent power system reform, it has come to be demanded that retail electric power suppliers supplying electric power to customers secure supply power equivalent to the power demand of their own customers.
Here, the power consumed by the consumer varies depending on the season, time zone, and the like. When a retail electricity company secures power generation equipment according to the largest demand, the operating rate of the power generation equipment decreases during periods and times when demand is low, making it difficult to use the power generation equipment efficiently. It is. On the other hand, if you do not secure the power generation equipment for the largest demand power, but purchase power from the wholesale power exchange as necessary, and the power price during the time of purchasing power is soaring Power procurement costs are high.
On the other hand, the conventional operation has a power generation facility and a storage battery, and supplements the amount of power required by the power generation facility secured by the retail electricity supplier with respect to the amount of power demand by the power stored in the storage battery. A method is known (for example, Patent Document 1). In addition, an operation method of a pumped-storage power plant that operates a pumped-storage power plant according to the amount of power demand and generates power according to a season or a time zone when the amount of power demand is large is known (for example, Patent Document 2).

In some cases, a demand adjustment method for selling and selling is implemented. Therefore, the retail electric utility may be able to reduce the cost for supplying power to the consumer by selling the power purchased at night to the consumer.

The electric power company EC is a business operator that comprehensively operates the electric power business, including ownership of power generation facilities including pumped storage power plants and transmission and distribution networks, power generation and distribution of electricity through the operation of these power generation facilities, and sales of electricity to consumers. Or a business group. In addition, the electric power company EC has at least a pumped-storage power plant EGP and trades the electric power generated by the pumped-storage power plant EGP, instead of being a business operator or a group of business operators that comprehensively conduct electricity business. It may be.

<About pumped storage power plant>
In the present embodiment, the electric power company EC is a pumping company that has a pumped storage power plant EGP and trades power generated by the pumped storage power plant EGP. The electric power company EC may further include a power plant other than the pumped storage power plant, for example, a hydro power plant that does not perform pumping, a thermal power plant, a wind power plant, and the like. As shown in FIG. 1, the pumped storage power plant EGP includes an upper pond UP, a lower pond LP, a pump P, and a generator M. The upper pond UP and the lower pond LP are ponds that store water used for power generation. Upper pond UP is a pond located at an altitude higher than lower pond LP. The pump P is a pump that pumps water stored in the lower pond LP to the upper pond UP. Hereinafter, a case where the pump P is a pump turbine will be described. The generator M is a device that generates electricity along with the rotation of the pump P by discharging water stored in the upper pond UP to the lower pond LP.

  Instead of the configuration in which the pump P is a pump turbine, the pump and the turbine may be configured separately. In this case, the pump rotates the water stored in the lower pond LP to the upper pond UP, and the water turbine rotates by discharging the water stored in the upper pond UP to the lower pond LP. The generator M generates power as the water turbine rotates.

<Loss of pumped storage power generation>
Here, the power generation by the pumped storage power plant EGP (hereinafter referred to as pumped-storage power generation) is the amount of power (hereinafter referred to as generated power EGE) obtained by discharging water with respect to the amount of power used for pumping (hereinafter referred to as pumped-electric power WPE). )Less is. In the pumped-storage power generation, energy loss (hereinafter referred to as “loss of energy LE”) occurs during pumping and power generation accompanying discharge due to the efficiency of the pump P provided by the pumped-storage power plant EGP, the efficiency of the generator M, and the head of loss. The amount of generated power EGE obtained for WPE is reduced. That is, in the pumped storage power plant EGP, an energy loss is generated by an amount of electric power (hereinafter referred to as a lost power amount LE) obtained by multiplying the pumped power amount WPE by a loss coefficient CL corresponding to the facility of the pumped storage power plant EGP.
Here, when the value of the pumped water amount WPE is WPE, the value of the generated power amount EGE is EGE, the value of the loss power amount LE is LE, and the value of the loss coefficient CL is CL, LE is the formula (1) Indicated by. Moreover, EGE is shown by Formula (2).

LE = WPE × CL (1)
EGE = WPE-LE (2)

  For example, when 30% of the pumped power amount WPE is lost due to pumped power generation (when the loss coefficient CL is 0.3), the lost power amount LE is obtained by multiplying the pumped power amount WPE by “0.3”. Amount. Here, when the pumping power amount WPE is “100,000 kWh”, the loss power amount LE is “30 million kWh”, and the generated power amount EGE is “70 million kWh”. is there. The loss coefficient CL may be a predetermined value, or may be a value that varies depending on the amount of water in the upper pond UP and the lower pond LP.

In addition, the retail electric utility AT may perform power transactions with the power company EC and the customer U. In this case, the retail electricity supplier AT is a trader that mediates the power generated by the power company EC and supplied to the consumer U. The retail electric company AT purchases electric power from the electric power company EC. Further, the retail electric company AT sells the purchased electric power to the consumer U who has a contract with the retail electric company AT.
The retail electric company AT purchases electric power supplied via the electric power system facility PN and generated by a power plant (in this example, a pumped storage power plant EGP) owned by the power company EC. The power system equipment PN is equipment such as a substation and a transmission / distribution line. In addition, the retail electric company AT sells electric power supplied via the electric power system facility PN to the consumer U, purchased from the electric power company EC and other retail electric companies AT. In this example, the consumers U who contract with the retail electricity supplier AT are the consumers U1, U2 and Un. n is an integer of 2 or more. In the following description, the customer U who makes a contract with the retail electric utility AT is simply referred to as the customer U. The retail electric utility AT may make a contract with a plurality of consumers U, or may make a contract with a single consumer U.
Here, the retail electric power company AT invests electric power in the electric power company EC and generates electricity by the pumped storage power plant EGP at a time different from the time when the electric power corresponding to the invested electric power is invested. There is a service (hereinafter referred to as a power storage service) that is supplied to the operator AT. Here, when the retail electricity supplier AT and the electric power company EC make a contract for the power storage service, this contract is a contract that is performed in consideration of the loss of electric power LE due to the pumped-storage power generation. In other words, the generated electric energy EGE obtained by the retail electric company AT by this contract is calculated from the pumped electric energy WPE invested by the retail electric company AT in order to obtain the generated electric power EGE. This is the generated electric energy EGE lost (subtracted) from the lost electric energy LE.

  In addition, elements other than the loss by pumped-storage power generation, such as transmission and distribution loss, may be included in the loss electric energy LE. The transmission / distribution loss is a loss when the power received or generated by the pumped storage power plant EGP is transmitted via the power system facility PN.

<About the profits of retail electricity companies>
The retail electric utility AT may obtain a lot of profits if it can purchase electric power cheaply from the electric power company EC. In addition, the electric power company EC may set and sell an electricity charge for nighttime power (hereinafter referred to as nighttime power) at a low price. In such a case, the retail electric utility AT can obtain a lot of profits if it can purchase electric power at night and sell it to the consumer U. For example, the retail electric company AT uses the nighttime power purchased by the retail electric company AT as the pumping power amount WPE for pumping. In addition, the retail electricity supplier AT gains profit by selling the generated power EGE generated by discharging the water pumped by the pumped power WPE to the customer U during the time when demand is concentrated. Get. That is, the electric power company EC and the retail electric company AT perform a power transaction between the pumped water amount WPE and the generated power amount EGE. Here, the retail electricity supplier AT performs a power transaction between the pumped water amount WPE and the generated power amount EGE so that a profit can be obtained even if the loss power amount LE accompanying the pumped water power generation is subtracted. .

  In the above description, the case where the pumping of the pumped storage power plant EGP is performed by the nighttime electric power purchased by the retail electric utility AT has been described, but is not limited thereto. Pumping of the pumped storage power plant EGP may be performed by electric power purchased by the retail electric utility AT other than at night. Moreover, the pumping of the pumped storage power plant EGP may be performed by surplus power excluding the power sold to the consumer U among the power purchased by the retail electric utility AT. Moreover, the pumping of the pumped storage power plant EGP may be performed by electric power generated by the facility of the retail electric utility AT.

<Contracts between electric power companies and retail electricity companies>

As shown in FIG. 3, the pumping plan information WPI includes a pumping period WT in which pumping is performed and a pumping power amount WPE consumed for pumping in the pumping period WT. In this example, the pumping period WT is indicated by a date DT and a time zone TZ. Therefore, the pumping plan information WPI includes the date DT, the time zone TZ of the date DT, and the pumping power amount WPE used for pumping the time zone TZ.
The date DT is information indicating the date when water is pumped by the pumping power amount WPE. The time zone TZ is information indicating a time zone during which water is pumped by consuming the pumped power amount WPE in the date DT. Here, the time zone TZ included in the pumping plan information WPI is divided for each transaction unit time AMT. The transaction unit time AMT is a unit of time during which the retail electric utility AT and the electric power company EC trade the pumped water amount WPE and the generated power amount EGE.

  The transaction unit time AMT may be a time unit longer than 30 minutes or a time unit shorter than 30 minutes. For example, the transaction unit time AMT may be 1 minute, 1 second, 15 minutes, or another time unit.

<About power generation plan information>
Hereinafter, the details of the power generation plan information EGI will be described with reference to the drawings.
FIG. 4 is a table showing an example of the power generation plan information EGI according to the first embodiment.
As illustrated in FIG. 4, the power generation plan information EGI includes a power generation period ET in which power generation is performed and a power generation amount EGE generated in the power generation period ET. In this example, the power generation period ET is indicated by a date DT and a time zone TZ. Therefore, the power generation plan information EGI includes the date DT, the time zone TZ of the date DT, and the generated power amount EGE generated in the time zone TZ.
As shown in FIG. 4, in this example, the power generation plan information EGI includes “2017/07/01” (date DT) “13: 0 to 16:00” (time zone TZ) every 30 minutes. A plan to generate “35,000 kWh” (power generation amount EGE) is shown.

Also good.
In addition, when the time zone TZ for performing pumping based on the pumping plan information WPI and the time zone TZ for generating power based on the power generation plan information EGI are determined in advance, the pumping period WT and the power generation period ET are based only on the date DT. May be shown.

<About the amount of pumped water and changes over time in the amount of generated power>
Hereinafter, with reference to FIG. 5, the time change between the pumped water power WPE and the generated power EGE will be described.
FIG. 5 is a graph showing temporal changes in the amount of pumped water and the amount of generated power according to the first embodiment.
The vertical axis | shaft of the graph shown in FIG. 5 shows the value of electric energy. Further, the horizontal axis of the graph shown in FIG. 5 indicates time. The waveform WWPE is a waveform showing the change over time of the pumped water energy WPE. The waveform WEGE is a waveform showing a change over time in the amount of generated power EGE.
As shown by the waveform WWPE, “050,000 to 4:00” of “2017/07/01” is used for pumping up “50,000,000 kWh” every 30 minutes. For this reason, the accumulation of the pumped water energy WPE increases between “0: 0 to 4:00” and “22: 0 to 24:00”. The accumulated pumping power WPE is “40 million kWh” at “4:00” and “60 million kWh” at “24:00”. Further, as indicated by the waveform WEGE, “35,000 kWh” is generated every 30 minutes at “13: 0 to 16:00” of “2017/07/01”. For this reason, the cumulative amount of generated power EGE increases during “13: 0 to 16:00”. Further, the accumulated power generation amount EGE is “21,000,000 kWh” at “16:00”.
Here, the generated power amount EGE is required to be a power amount corresponding to the pumped power amount WPE used for pumping before the generated power amount EGE is generated. In other words, it is required that the amount obtained by subtracting the accumulated amount of lost power from the accumulated amount of pumped power WPE used for pumping is required rather than the amount of generated power EGE generated by the retail electricity supplier AT.

  In addition, although the above demonstrated the case where the time slot | zone TZ contained in the pumping plan information WPI and the power generation plan information EGI was divided for every transaction unit time AMT, it is not restricted to this. The time zone TZ may be indicated by a unit of time that is not based on the transaction unit time AMT. For example, the pumping plan information WPI may include a pumping power amount WPE for each time zone TZ that is a predetermined time that is not based on the transaction unit time AMT. The power generation plan information EGI may include a power generation amount EGE for each time zone TZ that is a predetermined time that is not based on the transaction unit time AMT. In this case, the time zone TZ may be several hours, several days, or another unit of time. In addition, when the time zone TZ is indicated by a unit of time that is not based on the transaction unit time AMT, the plan determination apparatus 1 uses the pumping power amount WPE included in the pumping plan information WPI and the generated power amount EGE included in the power generation plan information EGI. May be configured to plan by converting into pumped water energy WPE and generated power energy EGE according to transaction unit time AMT.

<About the configuration of the plan determination device: pumped water energy determination unit>
Returning to FIG. 2, the pumped-up electric energy determination unit 130 acquires the pumping plan information WPI from the pumping plan acquisition unit 110. The pumping power amount determination unit 130 determines whether the pumping plan information WPI is a plan capable of pumping based on the pumping power amount WPE indicated by the acquired pumping plan information WPI and the reference pumping power amount DWP. The reference pumping power amount DWP is the amount of power per unit time that can be consumed by pumping the pumped storage power plant EGP. The pumping power amount determination unit 130 determines that the pumping plan information WPI is a plan capable of pumping when the pumping power amount WPE is equal to or less than the reference pumping power amount DWP.

<Regarding the standard pumping energy>
Hereinafter, with reference to FIG. 6, the detail of the reference | standard pumping electric energy DWP is demonstrated.
FIG. 6 is a graph showing an example of the reference pumping power DWP according to the first embodiment. Specifically, FIG. 6 is a graph showing a temporal change in the pumping power amount WPE in “00:00 to 4:00” in the pumping plan information WPI shown in FIG.
In this example, a case where the reference pumping power amount DWP is “50,000,000 kWh” per 30 minutes (Δt shown in the figure) will be described. That is, when the pumping power amount WPE included in the pumping plan information WPI is greater than 50,000 kWh (reference pumping power amount DWP), the pumping power determination unit 130 is a plan that cannot pump. judge.

<About the configuration of the plan determination device: generated power amount determination unit>
Returning to FIG. 2, the generated power amount determination unit 140 acquires the power generation plan information EGI from the power generation plan acquisition unit 120.

Determine whether. The subtracted power BE is the power obtained by subtracting the integrated power generation amount AWP from the integrated pumping power amount AWP, the loss power amount LE obtained by multiplying the integrated pumping power amount AWP by the loss coefficient CL (hereinafter referred to as the integrated power loss amount TLE). Amount. The integrated pumping electric energy AWP is an electric energy obtained by integrating the pumping electric power WPE from the start time of the determination period TM to a certain time in the pumping period WT included in the determination period TM. Specifically, the integrated pumping power amount AWP is the total sum of pumping power amounts WPE from the start time of the determination period TM to a certain time in the determination period TM. The accumulated power generation amount AEG is the power amount obtained by integrating the generated power amount EGE up to a certain time in the power generation period ET included in the range of the determination period TM. Specifically, the integrated power generation amount AEG is the total sum of the power generation amount EGE from the start time of the determination period TM to a certain time in the determination period TM.

Determine whether or not.

  In addition, although the case where the electric power company EC and the retail electric company AT make a contract in consideration that the pumped water amount WPE is used for the auxiliary device has been described, the present invention is not limited thereto. For example, the retail electric utility AT may make a contract that does not consider that the pumped water amount WPE is used for auxiliary equipment. In this case, the subtraction electric energy BE is an electric energy obtained by subtracting the integrated loss electric energy TLE and the integrated power generation AEG from the integrated pumping electric energy AWP.

<About the plan judging device>
FIG. 14 is a diagram illustrating an example of the configuration of the plan determination device 5 according to the fifth embodiment.
As shown in FIG. 14, the plan determination device 5 of this embodiment includes a control unit 103 and a storage unit 605.
Here, the electric power company EC may make a contract for supplying electric power by a method other than the power storage service. For example, the electric power company EC may make a contract with the consumer U to supply electric power without going through the retail electric utility AT. In addition, the electric power company EC may make a contract to trade electric power in the electric power wholesale market. In this case, the pumping and power generation of the pumped storage power plant EGP is performed in consideration of the amount of power supplied by a method other than the power storage service.
Specifically, the pumping power determination unit 130 determines whether or not the pumping plan information WPI is a plan capable of pumping based on the pumping power WPE indicated by the pumping plan information WPI and the contracted pumping power CWP. judge. The contracted pumped energy CWP is the amount of power per unit time that can be consumed by the pumped storage power plant EGP performing pumping associated with the power storage service. Specifically, the pumping power amount determination unit 130 is a plan that allows the pumping plan information WPI to be pumped when the pumping power amount WPE is equal to or less than the reference pumping power amount DWP and equal to or less than the contracted pumping power amount CWP. Judge that there is.

To do. The contracted power generation amount CEG is the amount of power per unit time that can be generated when the pumped storage power plant EGP generates power associated with the power storage service. Specifically, the generated power amount determination unit 140 is a plan that allows the power generation plan information EGI to be generated when the generated power amount EGE is equal to or less than the reference generated power amount DEG and equal to or less than the contract generated power amount CEG. Judge that there is.

It is determined whether or not.
Here, the case where the subtracted power amount BE is greater than the contract upper limit threshold CUTH indicates that the pumped water amount WPE consumed by the power storage service is excessive. Excessive pumping power amount WPE means that the power storage service has exceeded the contracted pond capacity and pumped pumping power amount WPE.
In this case, the upper limit determination unit 150 determines that the pumping plan information WPI and the power generation plan information EGI are plans that cannot be executed.

Further, the lower limit determination unit 160 has the subtraction power amount BE equal to or greater than the lower limit threshold LTH and equal to or greater than the contract lower limit threshold CLTH based on the pumping plan information WPI included in the range of the determination period TM and the power generation plan information EGI. It is determined whether or not.
Here, the case where the subtracted power amount BE is smaller than the contract lower limit threshold CLTH indicates that the generated power amount EGE generated by the power storage service is excessive. The excessive amount of generated power EGE indicates that the retail electricity company AT has received excessive power from the pumped-storage company over the lower threshold LTH by the power storage service.
In this case, the lower limit determination unit 160 determines that the pumping plan information WPI and the power generation plan information EGI are plans that cannot be executed.

  In addition, the upper limit determination part 150 and the lower limit determination part 160 of this embodiment may determine the success or failure of the pumping plan information WPI and the power generation plan information EGI further based on the auxiliary machine power loss AML.

The success or failure of EGI is determined. According to the plan determination device 5 of the present embodiment, the power generated by the pumped storage power plant EGP is supplied by a method other than the power storage service, and the pumping plan information WPI is determined according to the amount of supplied power. It is possible to determine whether or not the pumping plan and the power generation plan indicated by the power generation plan information EGI can be implemented.
