上記電気事業において電力の需給管理を行う発電計画システムとしては、このように電力系統に連系して発電する夫々の電源装置の計画個別発電量の計画を一元化して行うように構成された発電計画システムが知られている(例えば、特許文献1を参照。)。
In an electricity business that supplies power via a power system to a plurality of consumers including customers who have installed such a power supply device, by centrally managing the operation of the power supply devices installed in each consumer As a result, the degree of freedom of operation of the power supply device is increased, and the overall energy cost can be reduced.

しかしながら、従来の発電計画システムのように、電気系統に連系して発電する全ての電源装置の計画個別発電量の計画を一元化して行う場合には、その予測及び計画するべきデータの総数が甚大なものとなり、処理速度の低下及びシステムの煩雑化の問題が生じる。特に、電源装置が設置された夫々の需要家において、その需要家での電力系統への逆潮流の可否やエネルギコスト等に応じて、夫々の電源装置の計画個別発電量を計画するように構成すれば、更なる処理速度の低下及びシステムの煩雑化が懸念される。   However, when the planned individual power generation plan of all power supply devices that generate power linked to the electrical system is unified as in the conventional power generation planning system, the total number of data to be predicted and planned is As a result, the processing speed decreases and the system becomes complicated. In particular, each consumer installed with a power supply unit is configured to plan the planned individual power generation amount of each power supply unit according to the possibility of reverse power flow to the power system at that customer, the energy cost, etc. If so, there is a concern that the processing speed will be further reduced and the system will become more complicated.

本発明は、上記の課題に鑑みてなされたものであり、その目的は、処理速度の低下やシステムの煩雑化等の問題を抑制した合理的な構成で、全体及び需要家でのエネルギコスト等の所定の評価値の低減を実現するべく、夫々の電源装置の計画個別発電量の計画を一元化して行うことができる発電計画システムを実現する点にある。   The present invention has been made in view of the above-mentioned problems, and its purpose is a rational configuration that suppresses problems such as a reduction in processing speed and complication of the system, the energy cost of the whole and customers, etc. In order to realize a reduction in the predetermined evaluation value, a power generation planning system capable of unifying the planned individual power generation amount plans of the respective power supply devices is realized.

上記目的を達成するための本発明に係る発電計画システムは、電源装置を設置した需要家を含む複数の需要家に対して電力系統を介して電力を供給する電気事業に用いられる発電計画システムであって、その第1特徴構成は、夫々の電源装置を、前記電力系統への逆潮流を許容する状態で発電する逆潮流許容電源装置と、前記電力系統への逆潮流を禁止する状態で発電する逆潮流禁止電源装置とに分類し、
夫々の前記逆潮流許容電源装置の計画個別発電量を計画する第一計画処理を実行する第一計画部と、当該第一計画部での計画結果に基づいて夫々の前記逆潮流禁止電源装置の計画個別発電量を計画する第二計画処理を実行する第二計画部とを各別に備えてなる点にある。
In order to achieve the above object, a power generation planning system according to the present invention is a power generation planning system used in an electric business for supplying electric power to a plurality of consumers including a consumer having a power supply device via an electric power system. The first characteristic configuration is that each power supply unit generates power in a state allowing reverse power flow in a state allowing reverse power flow to the power system, and power generation in a state prohibiting reverse power flow to the power system. Classify it as a reverse power flow prohibition power supply
A first planning unit that executes a first planning process for planning a planned individual power generation amount of each of the reverse power flow allowable power supply devices, and each of the reverse power flow prohibited power supply devices based on a plan result of the first planning unit. The second planning unit for executing the second planning process for planning the planned individual power generation amount is provided separately.

比較的数は少ない大規模の電源装置は、余剰電力を多く発生することができ、その余剰電力を別の需要家に販売すれば比較的大きなメリットを得ることができることから、上記逆潮流許容電源装置とされることが多く、一方、比較的数が多い小規模の電源装置は、余剰電力が少なく、その余剰電力を別の需要家に販売してもメリットが少ないことから、上記逆潮流禁止電源装置とされることが多い。
そして、上記第一特徴構成によれば、上記第一計画部により上記第一計画処理を実行することで、例えば全体のエネルギコスト等の所定の評価値の低減を目的としても、比較的数は少ない上記逆潮流許容電源装置のみを対象としていることから、夫々の上記逆潮流許容電源装置の計画個別発電量を迅速に計画することができる。従って、上記第一計画部では、処理速度の低下やシステムの煩雑化等の問題を抑制した合理的な構成で、全体の上記評価値の低減を実現し得るように、夫々の上記逆潮流許容電源装置の計画個別発電量を計画することができる。
また、上記第一計画部による上記第一計画処理を実行した後に、上記第二計画部により上記第二計画処理を実行することで、例えば夫々の逆潮流禁止電源装置が設置された夫々の需要家のエネルギコスト等の所定の評価値の低減を目的としても、上記第一計画処理で計画した夫々の上記逆潮流許容電源装置の計画個別発電量を固定し、上記逆潮流禁止電源装置のみを対象としていることから、夫々の上記逆潮流禁止電源装置の計画個別発電量を迅速に計画することができる。従って、上記第二計画部では、処理速度の低下やシステムの煩雑化等の問題を抑制した合理的な構成で、全体の上記評価値及び夫々の逆潮流禁止電源装置が設置された夫々の需要家の上記評価値の低減を実現し得るように、夫々の上記逆潮流禁止電源装置の計画個別発電量を計画することができる。
そして、将来の計画対象期間における夫々の逆潮流許容電源装置及び夫々の逆潮流禁止電源装置の個別発電量を、上記第一計画部による第一計画処理及び上記第二計画部による第二計画処理により計画した計画個別発電量に設定することで、全体及び需要家での上記評価値の低減を実現することができる。
以上のように、本発明により、処理速度の低下やシステムの煩雑化等の問題を抑制した合理的な構成で、全体及び需要家でのエネルギコスト等の所定の評価値の低減を実現するべく、夫々の電源装置の計画個別発電量の計画を一元化して行うことができる発電計画システムを実現することができる。
A relatively small number of large-scale power supply devices can generate a large amount of surplus power, and if the surplus power is sold to another consumer, a relatively large merit can be obtained. On the other hand, small-scale power supply devices with a relatively large number have a small surplus power, and there is little merit even if the surplus power is sold to another customer. Often used as a power supply.
And according to said 1st characteristic structure, by the said 1st plan part performing said 1st plan process, for the purpose of reduction of predetermined evaluation values, such as the whole energy cost, for example, a comparatively few number Since only a small number of the allowable reverse power flow devices are targeted, the planned individual power generation amount of each of the allowable reverse power flow devices can be quickly planned. Therefore, in the first planning section, each of the reverse power flow allowances can be realized so that the overall evaluation value can be reduced with a rational configuration that suppresses problems such as a reduction in processing speed and system complexity. The planned individual power generation amount of the power supply device can be planned.
In addition, after the first planning process is performed by the first planning unit, the second planning process is performed by the second planning unit, for example, each demand where each reverse power flow prohibition power supply device is installed. For the purpose of reducing a predetermined evaluation value such as the energy cost of a house, the planned individual power generation amount of each of the above-described reverse power flow allowable power supply devices planned in the above-mentioned first plan processing is fixed, and only the above reverse power flow prohibition power supply device is installed. Since it is the object, the planned individual power generation amount of each of the reverse power flow prohibition power supply devices can be quickly planned. Accordingly, in the second planning section, the overall evaluation value and the respective demands for the respective reverse power flow prohibition power supply devices are installed with a rational configuration that suppresses problems such as a reduction in processing speed and complication of the system. The planned individual power generation amount of each of the reverse power flow prohibition power supply devices can be planned so that the evaluation value of the house can be reduced.
Then, the individual power generation amounts of the respective reverse power flow allowable power supply devices and the respective reverse power flow prohibition power supply devices in the future planning target period are converted into the first plan processing by the first planning unit and the second plan processing by the second planning unit. By setting to the planned individual power generation amount planned by the above, it is possible to realize the reduction of the evaluation value in the whole and the customer.
As described above, according to the present invention, it is possible to realize a reduction in a predetermined evaluation value such as energy cost in the whole and a customer with a rational configuration that suppresses problems such as a decrease in processing speed and a complicated system. Thus, it is possible to realize a power generation planning system that can unify the planning of the planned individual power generation amount of each power supply device.

本発明に係る発電計画システムの第2特徴構成は、上記第1特徴構成に加えて、夫々の前記逆潮流禁止電源装置が、前記第二計画処理の実行前に、当該逆潮流禁止電源装置の計画個別発電量を計画し、
前記第二計画部が、前記第二計画処理において、夫々の前記逆潮流禁止電源装置の計画個別発電量に対する変更幅を計画するように構成されている点にある。
According to a second characteristic configuration of the power generation planning system according to the present invention, in addition to the first characteristic configuration described above, each of the reverse power flow prohibition power supply devices is connected to the reverse power flow prohibition power supply device before the execution of the second planning process. Plan planned individual power generation,
In the second planning process, the second planning unit is configured to plan a change width with respect to the planned individual power generation amount of each of the reverse power flow prohibition power supply devices.

上記第2特徴構成によれば、夫々の上記逆潮流禁止電源装置により、上記第二計画処理の実行前に、例えば当該逆潮流禁止電源装置が設置された需要家での評価値の低減を目的として計画個別発電量を独自で計画するように構成し、更に、上記第二計画部により、全体の評価値の低減のみを目的として、一層迅速に、夫々の逆潮流禁止電源装置の上記独自で計画した計画個別発電量を変更する形態で計画することで、需要家の評価値の低減を優先しながら、全体の評価値の低減を図ることができる。   According to the second feature configuration, for example, each of the reverse power flow prohibition power supply devices is configured to reduce an evaluation value at a customer in which the reverse power flow prohibition power supply device is installed, for example, before the execution of the second planning process. The planned individual power generation amount is independently planned, and moreover, the second planning unit can more quickly and independently implement each of the reverse power flow prohibition power supply devices for the purpose of reducing the overall evaluation value. By planning in the form of changing the planned planned individual power generation amount, the overall evaluation value can be reduced while giving priority to the reduction of the customer evaluation value.

本発明に係る発電計画システムの第3特徴構成は、上記第2特徴構成に加えて、前記第二計画部が、夫々の前記逆潮流禁止電源装置の計画個別発電量の変更可能幅の合計を総発電量可変幅として導出する総発電量可変幅導出処理を実行して、当該総発電量可変幅を前記第一計画部に送信し、
前記第一計画部が、前記第二計画部から受信した総発電量可変幅に基づいて前記第一計画処理を実行する点にある。
In the third characteristic configuration of the power generation planning system according to the present invention, in addition to the second characteristic configuration, the second planning unit calculates a total changeable width of the planned individual power generation amount of each of the reverse power flow prohibition power supply devices. Execute the total power generation variable width derivation process derived as the total power generation variable width, and transmit the total power generation variable width to the first planning unit,
The first planning unit executes the first planning process based on the total power generation variable range received from the second planning unit.

上記第3特徴構成によれば、上記第二計画部により上記総発電量可変幅導出処理を実行することにより、例えば逆潮流禁止電源装置の最大発電量及び最小発電量などの仕様を参照し、予め計画してある当該逆潮流禁止電源装置の計画個別発電量の変更可能幅を導出する。そして、夫々の逆潮流禁止電源装置の計画個別発電量の変更可能幅を合計したものを、夫々の逆潮流禁止電源装置の計画個別発電量を変更することにより変更可能な予測総受電量の幅と一致する総発電量可変幅を導出することができる。
そして、上記第一計画部により、後の上記第二計画部による第二計画処理により解消するべき過不足量が上記総発電量可変幅の範囲内となるように、その総発電量可変幅に基づいて上記第一計画処理を実行することで、上記第二計画部において確実にその過不足量を解消するように、上記第二計画処理を実行して、夫々の逆潮流禁止電源装置の計画個別発電量を変更することができる。
According to the third characteristic configuration, by executing the total power generation variable width derivation process by the second planning unit, for example, referring to specifications such as the maximum power generation amount and the minimum power generation amount of the reverse power flow prohibition power supply device, The changeable width of the planned individual power generation amount of the reverse power flow prohibition power supply device planned in advance is derived. Then, the total of the changeable range of the planned individual power generation amount of each reverse power flow prohibition power supply unit is changed to the range of the predicted total power reception amount that can be changed by changing the planned individual power generation amount of each reverse power flow prohibition power supply unit It is possible to derive the total power generation variable width that coincides with.
Then, the total power generation amount variable width is set by the first planning unit so that the excess / deficiency amount to be eliminated by the second planning process by the second second planning unit is within the range of the total power generation amount variable width. By executing the first planning process based on the above, the second planning process is executed so as to surely eliminate the excess / deficiency in the second planning section, and the plan of each reverse power flow prohibition power supply device is executed. Individual power generation can be changed.

本発明に係る発電計画システムの第4特徴構成は、上記第2乃至第3特徴構成に加えて、前記第一計画部が、前記第一計画処理の実行時の全体の所定の評価値に基づいて許容評価値増加量を決定する許容評価値増加量決定処理を実行して、当該許容評価値増加量を前記第二計画部に送信し、
前記第二計画部が、夫々の前記逆潮流禁止電源装置の計画個別発電量を前記第二計画処理で計画した変更幅分変更したときの全体の前記評価値の増加量が、前記第一計画部から受信した許容評価値増加量を越えるときには、夫々の前記逆潮流禁止電源装置の計画個別発電量の変更を禁止する計画個別発電量変更禁止処理を実行する点にある。
According to a fourth characteristic configuration of the power generation planning system according to the present invention, in addition to the second to third characteristic configurations, the first planning unit is based on an overall predetermined evaluation value when the first planning process is executed. The allowable evaluation value increase amount determining process for determining the allowable evaluation value increase amount is executed, and the allowable evaluation value increase amount is transmitted to the second planning unit,
When the second plan unit changes the planned individual power generation amount of each of the reverse power flow prohibition power supply units by the change width planned in the second plan process, the overall increase amount of the evaluation value is the first plan. When the allowable evaluation value increase amount received from the unit is exceeded, the planned individual power generation amount change prohibiting process for prohibiting the change of the planned individual power generation amount of each of the reverse flow prohibition power supply devices is executed.

上記第4特徴構成によれば、上記第一計画部により上記許容評価値増加量決定処理を実行して、夫々の前記逆潮流許容電源装置の計画個別発電量の計画したときの全体のエネルギコスト等の所定の評価値に基づいて、例えば当該評価値に対して過不足量を解消したときの全体の評価値の増加量を許容評価値増加量とする形態で、許容評価値増加量を決定し、第二計画部に送信することができる。
そして、上記第二計画部により計画個別発電量変更禁止処理を実行して、夫々の逆潮流禁止電源装置の計画個別発電量を上記第二計画処理で計画した変更幅分変更したときの全体の評価値増加量が、上記許容評価値増加量を越えるときには、夫々の逆潮流禁止電源装置の計画個別発電量を変更してもメリットが無いとして、夫々の前記逆潮流禁止電源装置の計画個別発電量の変更を禁止し、全体の評価値の無用な増加を抑制することができる。
According to the fourth feature configuration, the total energy cost when the first planning unit executes the allowable evaluation value increase amount determination processing and plans the planned individual power generation amount of each of the reverse flow allowable power supply devices. Based on a predetermined evaluation value such as, for example, the allowable evaluation value increase amount is determined in a form in which the increase amount of the entire evaluation value when the excess / deficiency amount is eliminated with respect to the evaluation value is set as the allowable evaluation value increase amount And can be sent to the second planning department.
Then, the planned individual power generation amount change prohibition process is executed by the second planning unit, and the total amount when the planned individual power generation amount of each reverse power flow prohibition power supply device is changed by the change width planned in the second plan processing is changed. When the evaluation value increase amount exceeds the allowable evaluation value increase amount, there is no merit in changing the planned individual power generation amount of each reverse power flow prohibition power supply device. Changing the amount can be prohibited, and an unnecessary increase in the overall evaluation value can be suppressed.

本発明に係る発電計画システムの実施の形態について、図面に基づいて説明する。
図1は、特定規模電気事業者(以下、「PPS」(Power Producer and Supplier)と呼ぶ。)が電力を、電力系統1を介して複数の需要家3へ供給する電気事業の様子及びその電気事業に用いられる発電計画システム10の概略構成を示す図であり、図2は、本発明に係る発電計画システム10により実行される発電計画処理のフロー図である。
An embodiment of a power generation planning system according to the present invention will be described with reference to the drawings.
FIG. 1 shows a state of an electric business in which a specific scale electric power company (hereinafter referred to as “PPS” (Power Producer and Supplier)) supplies electric power to a plurality of consumers 3 through an electric power system 1 and its electric power. It is a figure which shows schematic structure of the power generation planning system 10 used for a business, and FIG. 2 is a flowchart of the power generation planning process performed by the power generation planning system 10 which concerns on this invention.

図1に示すように、夫々の需要家3は、電気機器などのように電力を消費する電力負荷4を有し、その電力負荷4における電力需要を電力系統1の受電電力等で賄う。   As shown in FIG. 1, each consumer 3 has a power load 4 that consumes power, such as an electrical device, and covers the power demand in the power load 4 with the received power of the power system 1 or the like.

また、複数の需要家3の少なくとも一部には、コージェネレーション装置や蓄放電装置などのように、電力負荷4における電力需要の少なくとも一部を賄う形態で電力を発生可能な電源装置Gが夫々設けられている。
具体的には、複数の需要家3の一部である逆潮流許容需要家3aには、電力系統1への逆潮流を許容する状態、即ち当該需要家3aの電力負荷4における電力需要量に関係無く発電を行う逆潮流許容電源装置Gaが設けられており、一方、複数の需要家3の一部である逆潮流禁止需要家3bには、電力系統1への逆潮流を禁止する状態、即ち当該需要家3bの電力負荷4における電力需要量を越えない範囲で発電を行う逆潮流禁止電源装置Gbが設けられている。
Further, at least a part of the plurality of consumers 3 is a power supply device G that can generate power in a form that covers at least a part of the power demand in the power load 4, such as a cogeneration device or a storage / discharge device. Is provided.
Specifically, the reverse power flow allowable consumer 3a, which is a part of the plurality of consumers 3, is allowed to have a reverse power flow to the power system 1, that is, the amount of power demand in the power load 4 of the consumer 3a. A reverse flow allowable power supply device Ga that generates power irrespectively is provided, while the reverse flow prohibition consumer 3b that is a part of the plurality of consumers 3 prohibits reverse flow to the power system 1, That is, there is provided a reverse power flow prohibiting power supply Gb that generates power within a range not exceeding the amount of power demand in the power load 4 of the consumer 3b.

尚、夫々の需要家3において、電力負荷4で消費される電力量を個別電力需要量、電源装置Gで発生される電力量を個別発電量、電力系統1から電力負荷4に供給される電力量を個別受電量と呼ぶ。ここで、この個別受電量は、正の値の場合には、電力系統1側から需要家3側へ電力が供給される状態を表し、逆に、負の値の場合には需要家3側から電力系統1側へ電力が供給される状態を表す。
また、上記夫々の需要家3における上記個別受電量等は、上記PPSが運用するネットワーク型コンピュータシステムである需要管理システム20により管理されている。即ち、需要管理システム20は、複数の需要家3の過去における個別受電量、個別発電量、個別電力需要量の実績値を、実個別受電量、実個別発電量、実個別電力需要量として需要データベース(需要DB)21に格納するように構成されている。尚、これら実個別受電量や実個別発電量は、電力系統1と夫々の需要家3の間に設置された公知の電力メータや電源装置Gに設置された電力メータ等により計測することができ、また、実個別電力需要量は、実個別電力受電量と実個別発電量との和として求めることができる。
In each consumer 3, the amount of power consumed by the power load 4 is the individual power demand amount, the amount of power generated by the power supply G is the individual power generation amount, and the power supplied from the power system 1 to the power load 4. The amount is referred to as an individual received amount. Here, when the individual power reception amount is a positive value, it represents a state in which power is supplied from the power system 1 side to the customer 3 side. Conversely, when the individual power reception amount is a negative value, the customer 3 side Represents a state in which power is supplied from the power system 1 to the power system 1 side.
In addition, the individual power reception amount and the like in each of the consumers 3 is managed by a demand management system 20 that is a network type computer system operated by the PPS. That is, the demand management system 20 uses the actual values of individual received power, individual generated power, and individual power demand in the past of the plurality of consumers 3 as actual individual received power, actual individual generated power, and actual individual power demand. The database (demand DB) 21 is configured to be stored. The actual individual power reception amount and the actual individual power generation amount can be measured by a known power meter installed between the power system 1 and each consumer 3, a power meter installed in the power supply device G, or the like. In addition, the actual individual power demand can be obtained as the sum of the actual individual power reception amount and the actual individual power generation amount.

更に、上記需要管理システム20は、上記需要データベース21に格納されている過去の実個別電力需要量に基づいて、将来の個別電力需要量を予測個別電力需要量として予測し、この予測個別電力需要量も併せて需要DB21に格納するように構成されている。
例えば、需要管理システム20は、将来の所定日の月日、曜日、天候などの属性と同じ属性を有する実個別電力需要量を上記需要量DB21から抽出し、その抽出した実個別電力需要量の夫々の平均値などを、上記将来の所定日における予測個別電力需要量とする形態の予測方法やその他の公知の予測方法を利用することができる。尚、需要管理システム20は、夫々の需要家3に電力を供給する将来の実行時としての当日における夫々の需要家3の予測個別電力需要量を、実行時の前である前日の計画時の前に予測して需要DB21に格納する。
Further, the demand management system 20 predicts a future individual power demand as a predicted individual power demand based on the past actual individual power demand stored in the demand database 21, and this predicted individual power demand. The amount is also stored in the demand DB 21 together.
For example, the demand management system 20 extracts the actual individual power demand having the same attributes as the month, day of the week, and the weather of a predetermined day in the future from the demand DB 21, and the extracted actual individual power demand It is possible to use a prediction method in which each average value or the like is used as the predicted individual power demand amount in the future predetermined day or other known prediction methods. It should be noted that the demand management system 20 calculates the predicted individual power demand of each customer 3 on the day as the future execution time when power is supplied to each customer 3 at the time of planning the previous day before execution. Predicted before and stored in the demand DB 21.

また、需要家3としては、上記のように電源装置Gを設置した需要家3a,3b以外に、電源装置Gが設置されておらず、電力負荷4における電力需要量の全てを電力系統1からの受電電力で賄う需要家3cを含んでも構わない。
また、この電力系統1としては、別の電力会社が運営管理する送電線を利用しても構わないが、上記PPSが自ら運営管理する自営線を利用しても構わない。
Moreover, as the consumer 3, the power supply apparatus G is not installed other than the consumers 3a and 3b in which the power supply apparatus G is installed as described above, and all of the power demand amount in the power load 4 is supplied from the power system 1. The customer 3c covered by the received power may be included.
Moreover, as this electric power grid | system 1, you may utilize the power transmission line which another electric power company manages and manages, but you may utilize the private line which said PPS manages and manages itself.

上記PPSの電力調達形態は、自ら運用する発電装置Goや上記逆潮流許容電源装置Gaの発生電力を電力系統1に供給する形態の他、外部の市場で購入した購入電力を電力系統1に供給する形態等があり、全ての需要家3の個別受電量の合計と同量の電力が、上記夫々の電力調達形態で調達される。尚、外部電力調達先は、上記市場に限らず、他の電力事業者や電力会社等としても構わない。   The power procurement form of the PPS supplies power system 1 with purchased power purchased in an external market in addition to the form of supplying power generated by the power generator Go operated by itself or the reverse power flow allowable power supply apparatus Ga to the power system 1 The same amount of electric power as the total of individual received amounts of all the consumers 3 is procured in each of the above-mentioned electric power procurement forms. Note that the external power supply source is not limited to the above market, and may be another electric power company, an electric power company, or the like.

上記PPSが運用するネットワーク型コンピュータシステムとして、上記発電装置Goや需要家3a,3bに設けられた夫々の電源装置Ga,Gbの個別発電量を計画するための発電計画システム10が設けられている。
更に、この発電計画システム10は、夫々の電源装置Gを上述した逆潮流許容電源装置Gaと逆潮流禁止電源装置Gbとに分類して、夫々の逆潮流許容電源装置Gaに対応付けられて設けられた第一計画システム(第一計画部の一例)11と、夫々の逆潮流禁止電源装置Gbに対応付けられて設けられた第二計画システム(第二計画部の一例)12とを、互いに通信可能な状態で各別に備えてなる発電計画システム10が設けられている。そして、上記第一計画システム11が、夫々の逆潮流許容電源装置Gaの計画個別発電量を計画する第一計画処理を実行し、次に、上記第二計画システム12が、当該第一計画システム11での計画結果に基づいて夫々の逆潮流禁止電源装置Gbの計画個別発電量を計画する第二計画処理を実行するように構成されている。
As a network type computer system operated by the PPS, a power generation planning system 10 for planning individual power generation amounts of the power generation apparatuses Go and the respective power supply apparatuses Ga and Gb provided in the consumers 3a and 3b is provided. .
Further, the power generation planning system 10 is provided by classifying each power supply device G into the above-described reverse flow allowable power supply device Ga and reverse flow allowable power supply device Gb, and corresponding to each reverse flow allowable power supply device Ga. The obtained first planning system (an example of the first planning unit) 11 and a second planning system (an example of the second planning unit) 12 provided in association with each reverse power flow prohibiting power supply device Gb are mutually connected. A power generation planning system 10 provided separately for each in a communicable state is provided. And the said 1st plan system 11 performs the 1st plan process which plans the plan separate electric power generation amount of each reverse power flow allowable power supply device Ga, Then, said 2nd plan system 12 is said 1st plan system 11 is configured to execute a second planning process for planning the planned individual power generation amount of each reverse power flow prohibition power supply Gb based on the planning result at No. 11.

即ち、発電計画システム10は、第一計画システム11と第二計画システム12と夫々の電源装置Gとが一体となって、夫々の需要家3に電力を供給する将来の実行時としての当日における夫々の電源装置Gの個別発電量を計画するべく、実行時の前である前日の所定の計画時、更には、実行時である当日に、所定の処理を実行するように構成されており、その処理のフローについて、図2に基づいて説明する。   In other words, the power generation planning system 10 includes the first planning system 11, the second planning system 12, and the respective power supply devices G as a unit, and supplies power to each consumer 3 on the day of the future execution. In order to plan the individual power generation amount of each power supply device G, it is configured to execute a predetermined process at a predetermined planning day before the execution time, and further, on the day of the execution time, The processing flow will be described with reference to FIG.

先ず、前日において発電計画システム10により実行される計画処理について説明する。
前日の計画処理では、先ず、逆潮流禁止電源装置Gbが、上記第二計画システム12による第二計画処理の実行前に、当該逆潮流禁止電源装置Gbの計画個別発電量を計画する運転計画処理(ステップ#11)を実行する。
例えば、逆潮流禁止電源装置Gbは、上記運転計画処理(ステップ#11)において、上述した需要DB21から抽出して又は自ら予測して逆潮流禁止需要家3bにおける予測個別電力需要量を取得し、計画個別発電量がその予測個別電力需要量を越えない範囲内、即ち電力系統1への逆潮流が発生しない範囲内で、当該逆潮流禁止電源装置Gbの計画個別発電量を、例えば逆潮流需要家の電力需要や熱需要等に基づいて計画する。
即ち、この運転計画処理(ステップ#11)により、夫々の逆潮流禁止需要家3bにおいて、エネルギコスト(評価値の一例)の低減を目的として、逆潮流禁止電源装置3bの計画個別発電量を独自に計画することができる。
尚、上記運転計画処理(ステップ#11)で計画された逆潮流禁止電源装置3bの計画個別発電量は、後述する第二計画処理(ステップ#15)で計画される変更幅分変更される場合があることから、逆潮流禁止電源装置3bの仮の計画個別発電量となる。
First, the planning process executed by the power generation planning system 10 on the previous day will be described.
In the planning process of the previous day, first, the operation plan process in which the reverse power flow prohibiting power supply Gb plans the planned individual power generation amount of the reverse power flow prohibiting power supply Gb before the execution of the second planning process by the second planning system 12. (Step # 11) is executed.
For example, in the operation planning process (step # 11), the reverse power flow prohibition power supply device Gb acquires the predicted individual power demand amount in the reverse power flow prohibition consumer 3b extracted from the demand DB 21 described above or predicted by itself. Within the range where the planned individual power generation amount does not exceed the predicted individual power demand amount, that is, within the range where no reverse power flow to the power system 1 occurs, the planned individual power generation amount of the reverse power flow prohibition power supply Gb is, for example, reverse power flow demand Plan based on household electricity demand and heat demand.
That is, by this operation planning process (step # 11), each of the reverse power flow prohibition consumers 3b independently generates the planned individual power generation amount of the reverse power flow prohibition power supply device 3b for the purpose of reducing the energy cost (an example of an evaluation value). Can be planned.
When the planned individual power generation amount of the reverse power flow prohibition power supply device 3b planned in the operation planning process (step # 11) is changed by the change width planned in the second planning process (step # 15) described later. Therefore, it becomes the provisional planned individual power generation amount of the reverse power flow prohibition power supply device 3b.

尚、上記エネルギコストとは、単位電力量あたりの電力を発生するのに必要な発電コストを示し、例えば、発電コストは、単位電力量あたりの電力を発生するときに電源装置Gが消費する一次エネルギ費用や運用費用の合計として計算することができる。また、上記電源装置Gが電力に加えて熱をも発生するコージェネレーション装置である場合には、上記エネルギコストを、上記発電コストから、上記電源装置Gが発生した熱により削減されたエネルギ料金の削減量を差し引いたものとして計算しても構わない。   The energy cost indicates a power generation cost necessary to generate power per unit power amount. For example, the power generation cost is a primary power consumed by the power supply device G when generating power per unit power amount. It can be calculated as the sum of energy costs and operating costs. In addition, when the power supply device G is a cogeneration device that generates heat in addition to electric power, the energy cost is reduced from the power generation cost to the energy charge reduced by the heat generated by the power supply device G. You may calculate as what reduced the amount of reduction.

次に、上記第二計画システム12は、夫々の逆潮流禁止電源装置Gbの計画個別発電量の変更可能幅の合計を総発電量可変幅として導出する総発電量可変幅導出処理(ステップ#12)を実行して、当該総発電量可変幅を前記第一計画システム11に送信する。
例えば、第二計画システム12は、上記総発電量可変幅導出処理(ステップ#12)において、夫々の逆潮流禁止電源装置Gbについて、最大発電量及び最小発電量などの仕様を参照し、逆潮流を禁止した状態を維持して、予め計画してある当該逆潮流禁止電源装置3bの計画個別発電量の変更可能幅を夫々導出する。そして、夫々の逆潮流禁止電源装置6bの計画個別発電量の変更可能幅を合計したものを総発電量可変幅として導出する。よって、このように導出した総発電量可変幅は、夫々の逆潮流禁止電源装置Gbの計画個別発電量を変更することにより変更可能な予測総受電量の幅と一致する。
Next, the second planning system 12 derives the total power generation amount variable width deriving process (step # 12) for deriving the total changeable width of the planned individual power generation amount of each reverse power flow prohibition power supply Gb as the total power generation amount variable width. ) To transmit the total power generation variable range to the first planning system 11.
For example, the second planning system 12 refers to the specifications such as the maximum power generation amount and the minimum power generation amount for each reverse power flow prohibition power supply Gb in the total power generation variable width derivation process (step # 12), and the reverse power flow Is maintained, and the changeable width of the planned individual power generation amount of the reverse power flow prohibition power supply device 3b planned in advance is derived. Then, the total changeable width of the planned individual power generation amount of each reverse power flow prohibition power supply device 6b is derived as the total power generation variable width. Therefore, the total power generation amount variable width derived in this way matches the width of the predicted total power reception amount that can be changed by changing the planned individual power generation amount of each reverse power flow prohibition power supply Gb.

次に、上記第一計画システム11は、後の上記第二計画システム12による第二計画処理(ステップ#12)により解消するべき過不足量が、上記第二計画システム11から受信した総発電量可変幅の範囲内となるように、その総発電量可変幅に基づいて、夫々の前記逆潮流許容電源装置Gaの計画個別発電量、更には、自ら運用する発電装置Goや外部等から調達する電力調達量を計画する第一計画処理(ステップ#13)を実行して、当該過不足量を前記第二計画システム12に送信する。
即ち、この第一計画処理(ステップ#13)により、全体のエネルギコストの低減を実現し得るように、夫々の上記逆潮流許容電源装置Gaの計画個別発電量等を計画することができる。
尚、上記目標総給電量は、需要DB21から抽出した予測個別電力需要量の合計から、発電装置Goの計画発電量の合計、外部の市場から購入した計画購入電力量の合計等を差し引いたものとして設定される。
また、上記発電装置Goの計画発電量は、上記逆潮流許容電源装置Gaの計画発電量と同時に計画するように構成しても構わない。
よって、上記第一計画処理(ステップ#13)では、処理速度の低下やシステムの煩雑化等の問題を抑制した合理的な構成で、全体のエネルギコストの低減を実現し得るように、夫々の上記逆潮流許容電源装置Gaの計画個別発電量が計画される。
そして、この第一計画処理(ステップ#13)で計画された夫々の計画個別発電量が、夫々の逆潮流許容電源装置Gaに送信される。
Next, the first planning system 11 determines that the excess or deficiency amount to be solved by the second planning process (step # 12) by the second planning system 12 is the total power generation amount received from the second planning system 11. Procured from the planned individual power generation amount of each of the reverse power flow allowable power supply devices Ga based on the total power generation variable width so as to be within the range of the variable width, and further from the power generation device Go operated by itself or the outside The first planning process (step # 13) for planning the power procurement amount is executed, and the excess / deficiency amount is transmitted to the second planning system 12.
That is, by this first planning process (step # 13), it is possible to plan the planned individual power generation amount and the like of each of the reverse flow allowable power supply devices Ga so that the overall energy cost can be reduced.
The target total power supply amount is obtained by subtracting the total planned power generation amount of the power generator Go, the total planned power purchase amount purchased from the external market, etc. from the total predicted individual power demand amount extracted from the demand DB 21. Set as
Further, the planned power generation amount of the power generation device Go may be configured simultaneously with the planned power generation amount of the reverse flow allowable power supply device Ga.
Therefore, in the first planning process (step # 13), each of the respective energy costs can be reduced with a rational configuration that suppresses problems such as a reduction in processing speed and complication of the system. The planned individual power generation amount of the reverse flow allowable power supply device Ga is planned.
Then, each planned individual power generation amount planned in the first planning process (step # 13) is transmitted to each reverse flow allowable power supply device Ga.

更に、上記第一計画システム11は、上記第一計画処理(ステップ#13)の実行時の全体のエネルギコストに基づいて許容コスト増加量を決定する許容コスト増加量決定処理(ステップ#14)を実行して、当該許容コスト増加量を第二計画システム11に送信する。
例えば、上記許容コスト増加量決定処理(ステップ#14)では、上記第一計画処理(ステップ#13)において、全体のエネルギコストの低減を優先した場合の全体のエネルギコストに対して、目標総給電量に対する計画総給電量の過不足量の解消を優先した場合の全体のエネルギコストの増加量を、上記許容コスト増加量として決定する。
Further, the first planning system 11 performs an allowable cost increase determination process (step # 14) for determining an allowable cost increase based on the overall energy cost when the first planning process (step # 13) is executed. Execute and transmit the allowable cost increase amount to the second planning system 11.
For example, in the allowable cost increase determination process (step # 14), the target total power supply with respect to the overall energy cost when priority is given to the reduction of the overall energy cost in the first planning process (step # 13). The increase amount of the total energy cost when priority is given to the elimination of the excess or deficiency of the planned total power supply amount with respect to the amount is determined as the allowable cost increase amount.

次に、上記第二計画システム12は、第一計画システム11から受信した過不足量を解消するように、夫々の逆潮流禁止電源装置Gbの予め計画された計画個別発電量の変更幅を計画する第二計画処理(ステップ#15)を実行する。
即ち、この第二計画処理(ステップ#15)により、例えば30分の規定期間内での給電量と受電量とを3%以内の誤差で一致させる所謂同時同量の規則に従うために、上記過不足量を解消し、且つ、夫々の逆潮流禁止需要家3bのエネルギコスト及び全体のエネルギコストの低減を実現し得るように、予め夫々の逆潮流禁止需要家3bのエネルギコストの低減を目的として計画された夫々の逆潮流禁止電源装置Gbの計画個別発電量を変更する形態で、その変更量を計画することができる。即ち、上記過不足量を解消するための予測総受電量の変更幅が、夫々の逆潮流禁止電源装置Gbの計画個別発電量の変更幅として最適に分配されることになる。
よって、上記第二計画処理(ステップ#15)では、処理速度の低下やシステムの煩雑化等の問題を抑制した合理的な構成で、全体のエネルギコスト及び夫々の逆潮流禁止需要家3bのエネルギコストの低減を実現し得るように、夫々の上記逆潮流禁止電源装置Gbの計画個別発電量が計画される。
Next, the second planning system 12 plans the range of change in the planned individual power generation amount planned for each reverse power flow prohibition power supply Gb so as to eliminate the excess / deficiency received from the first planning system 11. The second planning process (step # 15) is executed.
That is, in order to comply with the so-called simultaneous same amount rule for matching the power supply amount and the power reception amount within a specified period of 30 minutes with an error of 3% or less by this second planning process (step # 15). For the purpose of reducing the energy cost of each reverse flow prohibited consumer 3b in advance so that the shortage can be resolved and the energy cost of each reverse flow prohibited consumer 3b and the overall energy cost can be reduced. The amount of change can be planned in the form of changing the planned individual power generation amount of each planned reverse power flow prohibition power supply Gb. That is, the change width of the predicted total power reception amount for eliminating the excess / deficiency amount is optimally distributed as the change width of the planned individual power generation amount of each reverse power flow prohibition power supply Gb.
Therefore, in the second planned process (step # 15), the overall energy cost and the energy of each reverse power flow prohibition consumer 3b are reduced with a rational configuration that suppresses problems such as a reduction in processing speed and complication of the system. The planned individual power generation amount of each of the reverse power flow prohibition power supply devices Gb is planned so that the cost can be reduced.

更に、上記第二計画システム12は、夫々の逆潮流禁止電源装置Gbの計画個別発電量を上記第二計画処理(ステップ#15)で計画した変更幅分変更したときの全体のエネルギコスト増加量を導出し、そのエネルギコスト増加量が第一計画システム11から受信した許容コスト増加量を越えるときには、夫々の逆潮流禁止電源装置Gbの計画個別発電量の変更を禁止する計画個別発電量変更禁止処理(ステップ#16)を実行する。
即ち、この計画個別発電量変更禁止処理(ステップ#16)では、エネルギコスト増加量が許容コスト増加量を超えない場合には、第二計画処理(ステップ#15)で計画された夫々の変更幅が、夫々の逆潮流禁止電源装置Gbに送信され、逆に、エネルギコスト増加量が許容コスト増加量を超える場合には、夫々の変更幅を夫々の逆潮流禁止電源装置Gbに送信することなく、第一計画システム11に、夫々の逆潮流禁止電源装置Gbの計画個別発電量の変更を禁止したことを通知するための変更禁止通知を送信する。
そして、夫々の逆潮流禁止電源装置Gbでは、上記変更幅を受信した場合には、予め計画した仮の計画個別発電量を当該受信した変更幅分変更したものを、最終的な計画個別発電量とし(ステップ#17)、一方、上記変更幅を受信しなかった場合には、予め計画した仮の計画個別発電量を最終的な計画個別発電量とする。
Further, the second planning system 12 increases the total energy cost when the planned individual power generation amount of each reverse power flow prohibition power supply Gb is changed by the change width planned in the second planning process (step # 15). When the energy cost increase exceeds the allowable cost increase received from the first planning system 11, the plan individual power generation amount change prohibition prohibiting the change of the individual power generation amount of each reverse power flow prohibition power supply Gb is prohibited. Processing (step # 16) is executed.
That is, in the planned individual power generation amount change prohibition process (step # 16), when the energy cost increase amount does not exceed the allowable cost increase amount, the respective change widths planned in the second plan process (step # 15). Is transmitted to each reverse power flow prohibition power supply device Gb, and conversely, when the amount of increase in energy cost exceeds the allowable cost increase amount, each change width is not transmitted to each reverse power flow prohibition power supply device Gb. The change prohibition notice for notifying that the change of the planned individual power generation amount of each reverse power flow prohibition power supply Gb is prohibited is sent to the first planning system 11.
And in each reverse power flow prohibition power supply device Gb, when the said change width is received, what changed the provisional plan individual power generation amount planned beforehand by the received change width is made into the final planned individual power generation amount. (Step # 17) On the other hand, when the change width is not received, the provisional planned individual power generation amount planned in advance is set as the final planned individual power generation amount.

上記変更禁止通知を受信した第一計画システム11は、その変更禁止通知を受信することにより、第二計画システム12に送信した過不足量が解消されないことを認識し、上述した第一計画処理(ステップ#13)と同様の再度計画処理を実行して、当該過不足量が解消されるように、夫々の前記逆潮流許容電源装置Gaの計画個別発電量を再計画する再計画処理(ステップ#18)を実行する。
即ち、この再計画処理(ステップ#18)により、同時同量の規則に従うために、当該過不足量を解消するように、予め夫々の逆潮流許容電源装置Gaの計画個別発電量等を再計画することができる。
そして、この再計画処理(ステップ#18)で計画された夫々の計画個別発電量が、夫々の逆潮流許容電源装置Gaに送信され、夫々の逆潮流許容電源装置Gaでは、前に受信した計画個別発電量が後に受信したものに変更される(ステップ#19)。
The first planning system 11 that has received the change prohibition notification recognizes that the excess / deficiency amount transmitted to the second planning system 12 is not eliminated by receiving the change prohibition notification, and the first planning process ( A re-planning process (step #) for re-planning the planned individual power generation amount of each of the reverse flow allowable power supply devices Ga so that the excess and deficiency amount is eliminated by executing the planning process again as in step # 13). 18) is executed.
That is, by this re-planning process (step # 18), in order to obey the rule of the same amount at the same time, the planned individual power generation amount of each reverse power flow allowable power supply device Ga is re-planned so as to eliminate the excess / deficiency amount. can do.
Then, each planned individual power generation amount planned in this re-planning process (step # 18) is transmitted to each reverse flow allowable power supply device Ga, and each reverse flow allowable power supply device Ga receives the previously received plan. The individual power generation amount is changed to the one received later (step # 19).

上記のように発電計画システム10による計画処理を実行することにより、夫々発電計画システム10から計画個別発電量を受信した夫々の電源装置Gは、当日において、当該受信した計画個別発電量に対して実際の個別発電量を一致させるように、運転制御を開始することで(ステップ#21,#22)、全体のエネルギコスト及び夫々の需要家3のエネルギコストの最適化が図られる。
また、例えば、電力系統1に逆潮流して電力を供給した逆潮流許容需要家3aに対してはその給電量に見合った対価、全体のエネルギコストの低減のために逆潮流禁止電源装置Gの計画個別発電量を変更した逆潮流禁止需要家3bについてはそのエネルギコストの低減に見合った対価を、PPSから支払うようにしても構わない。
By executing the planning process by the power generation planning system 10 as described above, each power supply device G that has received the planned individual power generation amount from the power generation planning system 10 has received the planned individual power generation amount on the day. By starting the operation control so as to match the actual individual power generation amounts (steps # 21 and # 22), the overall energy cost and the energy cost of each customer 3 can be optimized.
Further, for example, for a reverse flow allowable consumer 3a that has supplied power by reverse flow to the electric power system 1, a reverse flow prohibition power supply device G of the reverse flow flow prohibition power supply device G may be used in order to reduce the price and the total energy cost. You may make it pay from PPS the compensation commensurate with the reduction of the energy cost about the reverse power flow prohibition consumer 3b which changed the plan individual power generation amount.

次に、当日における発電計画システム10による処理について説明する。
第一計画システム11は、当日において、現在進行中の規定期間(例えば30分毎)における目標総給電量に対する計画総給電量の過不足量を監視し(ステップ#23)、その過不足量が許容量を超える場合には、第二計画システム12に、その過不足量と、その過不足量を解消する場合に許容される許容コスト増加量とを送信する。尚、この過不足量の監視(ステップ#23)は、第二計画システム12や需要管理システム20などの他のシステムで行っても構わない。
Next, processing by the power generation planning system 10 on that day will be described.
The first planning system 11 monitors the excess / deficiency amount of the planned total power supply amount with respect to the target total power supply amount during a specified period (for example, every 30 minutes) currently in progress (step # 23). When the allowable amount is exceeded, the excess / deficiency amount and the allowable cost increase amount that is permitted when the excess / deficiency amount is eliminated are transmitted to the second planning system 12. The monitoring of the excess / deficiency (step # 23) may be performed by other systems such as the second planning system 12 and the demand management system 20.

そして、発電計画システム10は、前日の計画処理に実行した第二計画処理(ステップ#15)及び計画個別発電量変更禁止処理(ステップ#16)及び再計画処理(ステップ#18)と同様の処理を適宜実行する。
即ち、第二計画システム11は、第一計画システム11から受信した現在進行中の規定期間における過不足量を解消するように、夫々の逆潮流禁止電源装置Gbの規定期間終了までの計画個別発電量の変更幅を計画する第二計画処理(ステップ#24)を実行する。
The power generation planning system 10 performs the same processes as the second planning process (step # 15), the planned individual power generation amount change prohibition process (step # 16), and the re-planning process (step # 18) executed in the planning process on the previous day. Is executed as appropriate.
In other words, the second planning system 11 plans individual power generation until the end of the specified period of each reverse power flow prohibition power supply Gb so as to eliminate the excess / deficiency amount received from the first planning system 11 in the currently specified period. A second planning process (step # 24) for planning the amount of change is executed.

更に、上記第二計画システム12は、夫々の逆潮流禁止電源装置Gbの計画個別発電量を上記第二計画処理(ステップ#24)で計画した変更幅分変更したときの全体のエネルギコスト増加量を導出し、そのエネルギコスト増加量が第一計画システム11から受信した許容コスト増加量を越えるときには、夫々の逆潮流禁止電源装置Gbの計画個別発電量の変更を禁止する計画個別発電量変更禁止処理(ステップ#25)を実行する。
即ち、この計画個別発電量変更禁止処理(ステップ#25)では、エネルギコスト増加量が許容コスト増加量を超えない場合には、第二計画処理(ステップ#24)で計画された夫々の変更幅が、夫々の逆潮流禁止電源装置Gbに送信され、逆に、エネルギコスト増加量が許容コスト増加量を超える場合には、夫々の変更幅を夫々の逆潮流禁止電源装置Gbに送信することなく、第一計画システム11に、夫々の逆潮流禁止電源装置Gbの計画個別発電量の変更を禁止したことを通知するための変更禁止通知を送信する。
そして、上記変更幅を受信した夫々の逆潮流禁止電源装置Gbでは、現在進行中の規定期間終了までの計画個別発電量が受信した変更幅分変更される(ステップ#26)。
Further, the second planning system 12 increases the total energy cost when the planned individual power generation amount of each reverse power flow prohibiting power supply Gb is changed by the change width planned in the second planning process (step # 24). When the energy cost increase exceeds the allowable cost increase received from the first planning system 11, the plan individual power generation amount change prohibition prohibiting the change of the individual power generation amount of each reverse power flow prohibition power supply Gb is prohibited. Processing (step # 25) is executed.
That is, in the planned individual power generation amount change prohibition process (step # 25), when the energy cost increase amount does not exceed the allowable cost increase amount, the respective change widths planned in the second plan process (step # 24). Is transmitted to each reverse power flow prohibition power supply device Gb, and conversely, when the amount of increase in energy cost exceeds the allowable cost increase amount, each change width is not transmitted to each reverse power flow prohibition power supply device Gb. The change prohibition notice for notifying that the change of the planned individual power generation amount of each reverse power flow prohibition power supply Gb is prohibited is sent to the first planning system 11.
Then, in each reverse power flow prohibition power supply Gb that has received the change width, the planned individual power generation amount until the end of the currently specified period is changed by the received change width (step # 26).

上記変更禁止通知を受信した第一計画システム11は、その変更禁止通知を受信することにより、現在進行中の規定期間における過不足量が解消されないことを認識し、当該過不足量が解消されるように、夫々の前記逆潮流許容電源装置Gaの規定期間終了までの計画個別発電量を再計画する再計画処理(ステップ#27)を実行する。
そして、この再計画処理(ステップ#27)で計画された夫々の計画個別発電量が、夫々の逆潮流許容電源装置Gaに送信され、夫々の逆潮流許容電源装置Gaでは、現在進行中の規定期間終了までの計画個別発電量が後に受信したものに変更される(ステップ#28)。
The first planning system 11 that has received the change prohibition notice recognizes that the excess / deficiency amount in the specified period currently in progress is not eliminated by receiving the change prohibition notice, and the excess / deficiency quantity is eliminated. As described above, the re-planning process (step # 27) for re-planning the planned individual power generation amount until the end of the specified period of each of the reverse flow allowable power supply devices Ga is executed.
Then, each planned individual power generation amount planned in this re-planning process (step # 27) is transmitted to each reverse flow allowable power supply device Ga. The planned individual power generation amount until the end of the period is changed to the one received later (step # 28).
