Description

本発明は、電力系統から受電する自家発電受電部に、電力系統に連系して発電する自家発電装置が設置され、前記自家発電装置を集中管理する自家発電装置集中管理システムに関する。 The present invention relates to self-generation power receiving section for receiving from the electric power system, private power generation device is installed to generate power interconnection to the power grid, to a self-generating apparatus centralized management system for centralized management of the private power generation equipment.

電力市場の部分自由化により、特定規模電気事業者は、自由化対象の大口の需要家（特定規模需要家：原則使用規模２，０００ＫＷ以上で２０ＫＶ特別高圧送電線から受電する需要家）に小売託送することが可能となった。   Due to the partial liberalization of the electric power market, specific-scale electric utilities will be retailed to large-scale customers to be liberalized (specific-scale customers: customers who receive power from 20 KV special high-voltage transmission lines with a usage scale of 2,000 KW or more). It became possible to send them by consignment.

よって、需要家における電力調達形態としては、従来からある一般電気事業者（以下、「電力会社」と呼ぶ。）及び新規参入した特定規模電気事業者の何れか一方から電力を調達する形態を採用することが可能である。   Therefore, as a form of power procurement in the consumer, a form in which power is procured from either a conventional general electric utility (hereinafter referred to as “electric power company”) or a newly entered specific-scale electric utility is adopted. Is possible.

また、前述の電気事業者による電力事業において、上記のような需要家である受電部に、主に受電部の需要電力を補うように構成されたコジェネレーションシステム等の自家発電装置が設置される場合がある。そして、このように受電部に自家発電装置が設置される場合には、電気事業者は、自家発電装置集中管理システムにおいて、自社で管理する自社管理発電装置に対する発電計画以外に、受電部に設置された自家発電装置の発電出力を制御することで、全体的な経済性及び省エネルギ性を最適とするような電気事業を実現することができると考えられる。   Moreover, in the electric power business by the above-mentioned electric power company, a self-power generation device such as a cogeneration system configured mainly to supplement the power demand of the power receiving unit is installed in the power receiving unit as a consumer as described above. There is a case. And when a private power generation device is installed in the power receiving unit in this way, the electric utility installs in the power receiving unit in addition to the power generation plan for the self-managed power generation device managed in-house in the private power generation device centralized management system It is considered that by controlling the power generation output of the generated private power generator, it is possible to realize an electric business that optimizes the overall economy and energy saving.

即ち、このような自家発電装置は、発電出力を、所定の定格発電出力以下の範囲内で、自家発電装置が設置された自家発電受電部における電力又は熱の需要状態等のエネルギ需要状態に基づいて決定された設定発電出力又は定格発電出力を基準に一定に設定された設定発電出力に制御する制御手段を備え、この制御手段は、その設定発電出力を上昇させる発電出力上昇制御を実行可能に構成される。   That is, such a private power generation device is based on an energy demand state such as a power or heat demand state in a private power generation receiving unit in which the private power generation device is installed within a range of a predetermined rated power generation output or less. Control means for controlling the set power output to be set to a constant value based on the set power output or the rated power output determined in this way, and this control means can execute power generation output increase control for increasing the set power output. Composed.

そして、電気事業者等により運用されるコンピュータシステム等として構成され、給電部から電力系統を介して受電部へ電力を託送する電気事業において自家発電装置集中管理システムは、自家発電受電部に設置され系統連系して発電する１以上の自家発電装置の発電出力を制御可能な発電出力上昇指令手段を備え、その発電出力上昇指令手段により、自家発電装置に対して発電出力上昇制御を実行させる発電出力上昇指令を実行することにより、その自家発電受電部の受電電力が上記自家発電装置の設定上昇電力分低下することにより、見かけ上、電力系統において設定上昇電力に相当する電力を調達したことになり、その調達電力を他の受電部等に託送したり、自社管理発電装置の発電出力をその調達電力分低下させることができる。   And in an electric business that is configured as a computer system or the like operated by an electric power company, etc., and entrusts power from the power feeding unit to the power receiving unit via the power system, the private power generator centralized management system is installed in the private power receiving unit. Power generation output increase command means capable of controlling the power generation output of one or more private power generation devices that generate power through grid connection, and the power generation output increase command means causes the private power generation apparatus to execute power generation output increase control. By executing the output increase command, the received power of the private power generation / reception unit is reduced by the set increase power of the private power generation device, and apparently the power corresponding to the set increase power is procured in the power system. Thus, the procured power can be entrusted to another power receiving unit or the like, or the power generation output of the self-managed power generation device can be reduced by the procured power.

しかしながら、上記自家発電受電部に設けられる発電装置は、通常、設定発電出力が定格発電出力以下に制限されているので、例えば、定格発電出力又はそれに近い発電出力で運転を行っている際には、上記発電出力上昇制御を実行して発電出力を上昇させることができない場合がある。よって、自家発電装置集中管理システムの発電出力上昇指令手段により発電出力上昇指令を実行しても、実際には自家発電装置の発電出力が上昇しない場合があり、結果、電力系統における電力不足が発生して、例えば、電力系統を管理する電力会社に対して上記電力不足の発生によるペナルティを支払わなければならない場合がある。   However, since the set power generation output of the power generation device provided in the private power reception unit is normally limited to the rated power output or less, for example, when operating at the rated power output or a power output close to it, In some cases, the power generation output cannot be increased by executing the power generation output increase control. Therefore, even if the power generation output increase command is executed by the power generation output increase command means of the private power generation device centralized management system, the power generation output of the private power generation device may not actually increase, resulting in power shortage in the power system. Thus, for example, there may be a case where a penalty due to the occurrence of the power shortage must be paid to an electric power company that manages the electric power system.

また、自家発電装置集中管理システムの発電出力上昇指令手段により発電出力上昇指令を実行した際に、確実に自家発電装置の発電出力を上昇させるために、自家発電装置の発電出力を常時監視しておき、発電出力に余裕がある特定の自家発電装置に対してのみ、発電出力上昇指令を実行することが考えられるが、上記自家発電装置の発電出力を常時監視するための装置が煩雑となり、更に、発電出力に余裕の無い自家発電装置に対しては発電出力上昇指令を実行しないので、発電出力上昇指令を実行することにより電力系統において調達できる電力が小さくなり、経済性及び省エネルギ性を十分に向上させることができない場合がある。   In addition, when the power generation output increase command is executed by the power generation output increase command means of the private power generation apparatus centralized management system, the power generation output of the private power generation apparatus is constantly monitored in order to reliably increase the power generation output of the private power generation apparatus. In addition, it is conceivable to execute a power generation output increase command only for a specific private power generation apparatus having a sufficient power generation output, but the apparatus for constantly monitoring the power generation output of the private power generation apparatus becomes complicated, and Because the power generation output increase command is not executed for private power generators that have insufficient power generation output, the power that can be procured in the power system is reduced by executing the power generation output increase command, which is economical and energy efficient. May not be improved.

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、オーバーヒートや摺動部の焼付き等の問題の発生を抑制しながら、発電出力上昇制御により確実に発電出力を設定上昇電力分上昇させることができる発電装置を実現し、更には、その発電装置からなる自家発電装置に対して発電出力上昇指令を実行することにより、電力系統において大きな電力を確実に調達可能な自家発電装置集中管理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 to reliably increase the power generation output by the power generation output increase control while suppressing the occurrence of problems such as overheating and seizure of the sliding portion. In-house power generation that realizes a power generation device that can increase the amount of power, and that can reliably procure large amounts of power in the power system by executing a power generation output increase command for the power generation device that consists of the power generation device The point is to realize a centralized management system.

上記目的を達成するための本発明に係る自家発電装置集中管理システムは、電力系統から受電する自家発電受電部に、電力系統に連系して発電する自家発電装置が設置され、前記自家発電装置を集中管理する自家発電装置集中管理システムであって、前記自家発電受電部が複数あると共に、複数の前記自家発電装置からなる自家発電装置群を集中管理するように構成され、前記自家発電装置は、発電出力を所定の定格発電出力以下の設定発電出力に制御する制御手段を備え、前記制御手段が、前記設定発電出力を上昇させる発電出力上昇制御を実行可能であり、前記発電出力上昇制御において、前記設定発電出力を前記定格発電出力よりも大きい定格超発電出力以下の範囲内で上昇させることを許容すると共に、前記設定発電出力が継続して前記定格発電出力を超える定格超運転時間を設定定格超運転時間以下に制限するように構成され、前記自家発電装置の夫々が備える前記制御手段に対して、前記設定発電出力を設定上昇期間において設定上昇電力分上昇させる形態で、前記発電出力上昇制御を実行させる発電出力上昇指令を実行可能な発電出力上昇指令手段と、前記自家発電装置の夫々についての前記設定定格超運転時間に関する定格超運転情報を格納する定格超運転情報データベースを備え、前記発電出力上昇指令手段が、前記発電出力上昇指令において、前記設定上昇期間を、前記定格超運転情報データベースに格納されている前記設定定格超運転時間以下に決定し、及び、前記発電出力上昇指令において、前記自家発電装置群の総発電出力を総設定期間に総設定電力分上昇させる形態で、前記発電出力上昇指令の実行対象とする前記自家発電装置である発電出力上昇指令対象を決定するように構成されている点にある。 In order to achieve the above object, a private power generation apparatus centralized management system according to the present invention includes a private power generation section that receives power from a power system, and a self-power generation apparatus that generates power linked to the power system. A self-power generation apparatus centralized management system for centrally managing a plurality of the self-power generation receiving units, and configured to centrally manage a self-power generation apparatus group including a plurality of the self-power generation apparatuses, , a control means for controlling the power output to a predetermined set electric power output rated power output below the control means is capable of executing a power output increase control for increasing the setting power output, in the power output increase control , thereby allowing the increase in atmospheric heard nominal ultrasonic power output in the range than the rated power output of the set power output, the setting power output is continuously Is configured to limit the serial rated super operating time exceeding the rated power output below the set rated ultra operation time setting, to the control means for each of said self-generating device comprises, in the setting up period the set power output Power generation output increase command means capable of executing a power generation output increase command for executing the power generation output increase control in a form of increasing the amount of increased power, and rated super operation information related to the set rated super operation time for each of the private power generators In the power generation output increase command, the power generation output increase command means stores the set increase period within the set rated super operation time stored in the rated super operation information database. And in the power generation output increase command, the total power output of the private power generation device group is divided into the total set power for the total set period. In the form of raising the, in that it is configured to determine the power output increase Directive autologous power generator to be run against the power output increase command.

即ち、本発明に係る自家発電装置集中管理システムにおいて、上記制御手段が、エネルギ需要状態に基づいて決定された設定発電出力又は一定の定格発電出力に決定された設定発電出力を上昇させる上記発電出力上昇制御において、設定発電出力を定格発電出力よりも大きい定格超発電出力以下の範囲内で上昇させることを許容されていることで、設定発電出力を確実に上昇させることができる。
更に、上記自家発電装置において、上記制御手段が、上記発電出力上昇制御において、設定発電出力が継続して定格発電出力を超える定格超運転時間が設定定格超運転時間以下に制限されていることで、上記定格超運転時間が過剰に継続されて、オーバーヒートや摺動部における焼付き等の問題の発生を抑制することができる。 That is, in the private power generator centralized management system according to the present invention, the control means increases the set power output determined based on the energy demand state or the set power output determined to be a constant rated power output. in increase control, that is allowed to be increased within the range of the large hearing rated super power output than the rated power output setting power output can be increased securely set power output.
Further, in the private power generation apparatus , the control means is configured such that in the power generation output increase control, a rated super-operation time in which the set power generation output continuously exceeds the rated power output is limited to a set rated super-operation time or less. The rated super-operation time is continued excessively, and the occurrence of problems such as overheating and seizure in the sliding portion can be suppressed.

加えて、自家発電装置との間で通信を行って該自家発電装置を集中管理するように構成されたコンピュータからなる自家発電装置集中管理システムにおいて、上記発電出力上昇指令手段が、上記発電出力上昇指令において、上記設定上昇期間を、上記定格超運転情報データベースに予め格納している上記設定定格超運転時間以下に決定することで、上記自家発電装置の制御手段に対して発電出力上昇制御を実行させて、オーバーヒートや摺動部における焼付き等の問題の発生を抑制可能な設定定格超運転時間以下の上記設定上昇期間に、設定発電出力を、定格超発電出力以下の範囲内での上記設定上昇電力分上昇させて、電力系統において、設定定格超運転時間以下に決定された上記設定上昇期間に上記設定上昇電力分の電力を調達することができる。  In addition, in the private power generation apparatus centralized management system comprising a computer configured to communicate with the private power generation apparatus to centrally manage the private power generation apparatus, the power generation output increase command means includes the power generation output increase In the command, the set increase period is determined to be equal to or less than the set rated super operation time stored in advance in the rated super operation information database, thereby executing the power generation output increase control for the control means of the private power generator. The set power output is set within the range below the rated super power output during the above set rise time, which is less than the set rated super power operating time, which can suppress the occurrence of problems such as overheating and seizure in the sliding part. Raise the amount of electric power to be raised, and procure the electric power for the set electric power increase in the electric power system during the above-mentioned set electric power increase period determined to be less than the set rated super-operation time. It can be.

更に加えて、本発明に係る自家発電装置集中管理システムにおいて、上記自家発電受電部が複数設けられている場合において、上記発電出力上昇指令手段が、上記自家発電装置群の総発電出力を総設定期間に総設定電力分上昇させる形態、即ち、その総設定期間における総設定電力を各自家発電装置について決定される設定上昇期間における設定上昇電力に割り当てる形態で、上記発電出力上昇指令対象を決定することができる。そして、その発電出力上昇指令対象に対して発電出力上昇指令を実行することで、電力系統において、総設定期間において比較的大きな総設定電力を調達することができ、例えば、その総設定期間において調達した総設定電力分の電力を、自家発電受電部以外の受電部における受電電力、給電部における給電電力を低下分等に、割り当てることができる。  In addition, in the private power generation apparatus centralized management system according to the present invention, when a plurality of private power generation receiving units are provided, the power generation output increase command means sets the total power generation output of the private power generation apparatus group as a total setting. The power generation output increase command target is determined in a form in which the total set power is increased during the period, that is, the total set power in the total set period is assigned to the set increase power in the set increase period determined for each private power generator. be able to. Then, by executing the power generation output increase command for the power generation output increase command target, it is possible to procure a relatively large total set power in the total setting period in the power system, for example, in the total setting period The power for the total set power can be allocated to the received power in the power receiving unit other than the self-powered power receiving unit, the power supplied to the power feeding unit, etc.

本発明に係る自家発電装置集中管理システムの第２特徴構成は、前記制御手段が、前記発電出力上昇制御を終了してから設定定格超運転間隔が経過するまでの間には、前記発電出力上昇制御の実行を禁止するように構成されている点にある。 According to a second characteristic configuration of the private power generation apparatus centralized management system according to the present invention, the control means increases the power generation output until the set rated super-operation interval elapses after the power generation output increase control is finished. The point is that the execution of the control is prohibited.

即ち、本発明に係る自家発電装置集中管理システムにおいて、上記制御手段が、上記発電出力上昇制御を終了してから、予め設定された上記設定定格超運転間隔が経過するまでの間には、上記発電出力上昇制御の実行を禁止するように構成されていることで、上記発電出力上昇制御により例えば設定発電出力が定格発電出力を超えることで比較的多くの発熱があったとしても、その発熱を十分に放熱した後に、次の発電出力上昇制御の実行が許可されることになり、オーバーヒートや摺動部における焼付き等の問題の発生を一層抑制することができる。 That is, in the private power generator centralized management system according to the present invention, the control means ends the power generation output increase control until the preset rated rated superoperation interval elapses. By being configured to prohibit the execution of the power generation output increase control, even if there is a relatively large amount of heat generated, for example, when the set power generation output exceeds the rated power generation output by the power generation output increase control, the heat generation is suppressed. After sufficiently radiating heat, execution of the next power generation output increase control is permitted, and problems such as overheating and seizure at the sliding portion can be further suppressed.

本発明に係る自家発電装置集中管理システムの第３特徴構成は、前記制御手段が、前記定格超運転時間を積算した積算時間が設定定格超運転積算時間を超えた時点以降には、前記発電出力上昇制御の実行を禁止するように構成されている点にある。 According to a third characteristic configuration of the private power generation apparatus centralized management system according to the present invention, after the time when the integrated time obtained by integrating the rated super-operating time exceeds the set rated super-operating integrated time, the control means outputs the power generation output. The point is that the execution of the ascent control is prohibited.

即ち、本発明に係る自家発電装置集中管理システムにおいて、上記制御手段が、上記定格超運転積算時間が、予め設定された上記設定定格超運転積算時間を超えた時点以降については、上記発電出力上昇制御の実行を禁止するように構成されていることで、上記定格超運転積算時間が上記設定定格超運転積算時間を超えることでオーバーヒートや摺動部の焼付き等の問題が発生する確率が高くなることを抑制することができる。更には、上記定格超運転積算時間が上記設定定格超運転積算時間に到達した際に、その旨を通知するように構成することで、その通知を認識した際に、適切なメンテナンス等を実施して、上記定格超運転積算時間をリセットし、再度発電出力上昇制御の実行を許可することができる。 That is, in the private power generator centralized management system according to the present invention, the control means increases the power generation output after the time when the rated super-operating integrated time exceeds the preset rated super-operating integrated time. By being configured to prohibit the execution of control, there is a high probability that problems such as overheating and seizure of sliding parts will occur when the rated super-operating cumulative time exceeds the set rated super-operating cumulative time. It can be suppressed. Furthermore, when the rated super-operating accumulated time reaches the set rated super-operated accumulated time, it is configured to notify that fact, and when the notice is recognized, appropriate maintenance etc. is performed. Thus, it is possible to reset the rated super-operation accumulated time and permit the execution of the power generation output increase control again.

本発明に係る自家発電装置集中管理システムの第４特徴構成は、前記定格超運転情報データベースが、前記定格超運転情報として、前記定格超発電出力と前記定格発電出力との差として設定される設定定格超電力に関する情報を格納するように構成され、
前記発電出力上昇指令手段が、前記発電出力上昇指令において、前記設定上昇電力を、前記定格超運転情報データベースに格納されている前記設定定格超電力以下に決定するように構成されている点にある。 A fourth characteristic configuration of the private power generator centralized management system according to the present invention is a setting in which the rated super operation information database is set as a difference between the rated super power output and the rated power output as the rated super operation information. Configured to store information about rated superpower,
The power output increase command means, in the power output increase command, there the setting increased electric power, in that the is configured to determine the set rated electromotive force below which is stored in the nominal ultrasonic operation information database .

即ち、本発明に係る自家発電装置集中管理システムにおいて、上記発電出力上昇指令手段が、上記発電出力上昇指令において、上記設定上昇電力を、上記定格超運転情報データベースに予め格納している上記設定定格超電力以下に決定することで、自家発電装置の設定発電出力を確実にその設定上昇電力分上昇させることができ、電力系統において、設定定格超運転時間以下に決定された上記設定上昇期間に、設定定格超電力以下に決定された上記設定上昇電力分の電力を、確実に調達することができる。   That is, in the private power generator centralized management system according to the present invention, the power generation output increase command means stores the set power increase in advance in the rated superoperation information database in the power generation output increase command. By determining the super power or less, the set power output of the private power generator can be reliably increased by the set power increase, and in the power system, during the above set power increase period determined below the set rated super operation time, It is possible to reliably procure power for the above set increase power determined to be equal to or lower than the set rated super power.

本発明に係る自家発電装置集中管理システムの第５特徴構成は、前記自家発電装置が停止する期間である停止期間と前記停止期間において前記自家発電装置が停止することで発電できなくなった分の設定発電出力に相当する停止電力とを、前記総設定期間と前記総設定電力として受け付けて、前記発電出力上昇指令手段に前記発電出力上昇指令を実行させる自家発電電力補給機能を有する点にある。 A fifth characteristic configuration of the private power generation apparatus centralized management system according to the present invention is a setting of a stop period, which is a period during which the private power generation apparatus stops, and an amount that cannot be generated by stopping the private power generation apparatus in the stop period. It has a self-generated power supply function that accepts stop power corresponding to the power generation output as the total set period and the total set power and causes the power generation output increase command means to execute the power generation output increase command.

即ち、本発明に係る自家発電装置集中管理システムにおいて、上記自家発電電力補給機能を有することで、例えば、ある自家発電装置が故障等により不意に停止した場合やメンテナンスにより計画的に停止した場合において、上記停止期間と上記停止電力とを総設定期間と総設定電力として受け付けて、上記発電出力上昇指令手段により発電出力上昇指令を実行させることができ、自家発電装置群の総発電出力を総設定期間に総設定電力分上昇させて、上記停止期間において自家発電装置が停止することで発電できなくなった分の設定発電出力に相当する停止電力を調達することができる。そして、例えば自家発電装置が停止する場合でも、別の給電部から電力を調達する必要が無くなり、電力会社等に対して自家発電装置の停止時に備えて電力を供給するための電力補給契約等を締結する必要が無くなる。 That is, in the private power generation apparatus centralized management system according to the present invention, by having the above-mentioned private power generation power supply function, for example, when a certain private power generation apparatus is unexpectedly stopped due to a failure or when it is intentionally stopped due to maintenance. , The stop period and the stop power can be received as a total set period and total set power, and the power generation output increase command can be executed by the power generation output increase command means, and the total power output of the private power generator group can be set as a total By increasing the total set power during the period, it is possible to procure stop power corresponding to the set power generation output for which power generation can no longer be performed by stopping the private power generator during the stop period. For example, even if the private power generation device stops, there is no need to procure power from another power supply unit, and a power supply contract for supplying power to the power company etc. in preparation for the stop of the private power generation device, etc. There is no need for fastening.

本発明に係る自家発電装置集中管理システムの第６特徴構成は、前記複数の自家発電受電部の受電電力を削減させる期間である削減期間と前記削減期間における前記総受電電力の削減量である削減電力とを、前記総設定期間と前記総設定電力として受け付けて、前記発電出力上昇指令手段に前記発電出力上昇指令を実行させる受電電力削減機能を有する点にある。 A sixth characteristic configuration of the private power generation apparatus centralized management system according to the present invention is a reduction period that is a period for reducing the received power of the plurality of private power reception units, and a reduction that is a reduction amount of the total received power in the reduction period It has a received power reduction function that accepts power as the total set period and the total set power, and causes the power generation output increase command means to execute the power generation output increase command.

即ち、本発明に係る自家発電装置集中管理システムにおいて、上記受電電力削減機能を有することで、例えば、上記受電電力があるピーク電力を超える可能性がある場合や電力系統に給電する給電部の給電電力を低減させたい場合などにおいて、上記削減期間と上記削減電力とを総設定期間と総設定電力として受け付けて、上記発電出力上昇指令手段により発電出力上昇指令を実行させることができ、自家発電装置群の総発電出力を上記削減期間に上記削減電力分上昇させて、上記受電電力を上記削減期間において上記削減電力分削減させることができる。 That is, in the private power generation apparatus centralized management system according to the present invention, by having the received power reduction function, for example, when there is a possibility that the received power may exceed a certain peak power, or feeding of a power feeding unit that feeds the power system In the case where it is desired to reduce the power, the power generation output increase command can be executed by the power generation output increase command means by receiving the reduction period and the power reduction as the total setting period and the total setting power. The total power generation output of the group can be increased by the reduced power during the reduction period, and the received power can be reduced by the reduced power during the reduction period.

本発明に係る自家発電装置集中管理システムの第７特徴構成は、前記電力系統から受電する受電部の受電電力が所定の計画受電電力を超過する期間である超過期間と前記超過期間における受電電力の超過量である超過電力とを、前記総設定期間と前記総設定電力として受け付けて、前記発電出力上昇指令手段に前記発電出力上昇指令を実行させる受電電力調整機能を有する点にある。 The seventh characteristic configuration of the private power generation apparatus centralized management system according to the present invention is an excess period in which the received power of the power receiving unit that receives power from the power system exceeds a predetermined planned received power, and the received power in the excess period. An excess power that is an excess amount is received as the total set period and the total set power, and has a received power adjustment function that causes the generated output increase command means to execute the generated output increase command.

即ち、本発明に係る自家発電装置集中管理システムにおいて、上記受電電力調整機能を有することで、例えば、自家発電受電部やその他の受電部の１つ又は複数における上記受電電力が過去の受電電力等から導出された又は一定の計画受電電力を超える場合において、上記超過期間と上記超過電力とを総設定期間と総設定電力として受け付けて、上記発電出力上昇指令手段により発電出力上昇指令を実行させることができ、自家発電装置群の総発電出力を上記超過期間に上記超過電力分上昇させて、上記受電電力が計画受電電力を超えることを抑制することができ、例えば、上記受電電力が上記計画受電電力を超える場合における電力系統への給電電力の増加や他の電力事業者からの電力調達を回避することができる。 That is, in the private power generation apparatus centralized management system according to the present invention, by having the received power adjustment function, for example, the received power in one or more of the private power generation receiving unit and other power receiving units is the past received power, etc. In the case where the power consumption exceeds a certain planned received power derived from the above, the excess period and the excess power are received as the total set period and the total set power, and the generated power output increase command means executes the generated power output increase command. It is possible to increase the total power output of the private power generator group by the excess power during the excess period and to prevent the received power from exceeding the planned received power. For example, the received power is the planned received power It is possible to avoid an increase in the power supplied to the power system and the procurement of power from other power companies when the power exceeds the power.

It is explanatory drawing which showed the mode of the electric power retail consignment business which consigns using the electric power grid | system 5 which is the power transmission line which an electric power company manages and manages.

上記電力小売託送事業において、受電部１の一部である複数の自家発電受電部１ａには、図２に示すように、ガス供給管３０から供給されたガスを消費して運転されて発電するコジェネレーションシステム等の自家発電装置２０（発電装置）が設置されている。
また、この自家発電装置２０で発電した電力の内、その自家発電受電部１ａの電力消費部２８で消費される電力以外の余剰電力は、電力系統５に逆潮流されて他の受電部１側に託送可能とされている。
尚、上記自家発電装置２０は、上記コジェネレーションシステム以外の、例えばガス以外の燃料を消費して発電する発電装置として構成しても構わない。 In the electric power retail consignment business, as shown in FIG. 2, the plurality of private power generation / reception units 1a, which are part of the power reception unit 1, are operated by consuming the gas supplied from the gas supply pipe 30 to generate power. A private power generation device 20 (power generation device) such as a cogeneration system is installed.
In addition, surplus power other than the power consumed by the power consuming unit 28 of the private power receiving unit 1a out of the power generated by the private power generation device 20 is reversely flowed to the power system 5 and is on the other power receiving unit 1 side. Can be consigned to.
The private power generation device 20 may be configured as a power generation device that generates power by consuming fuel other than gas, for example, other than the cogeneration system.

従って、ＰＰＳは、受電部１の需要電力の全部又はその一部である給電対象需要電力を、自社管理発電装置１１で発電した電力と、自家発電受電部１ａの自家発電装置２０で発電した電力とにより満足させるように、電力託送を実施する。   Therefore, the PPS generates power that is generated by the self-managed power generation device 11 and the power generated by the private power generation device 20 of the private power generation / reception unit 1a for the power supply target power that is all or part of the demand power of the power reception unit 1. We will carry out power consignment so that we can be more satisfied.

尚、上記給電対象需要電力が、受電部１の需要電力の一部である場合には、その他のインバランス電力を、電力会社や他の電力取引市場等からの買電により満足させることができる。   When the power supply target power is a part of the power demand of the power receiving unit 1, other imbalanced power can be satisfied by purchasing power from an electric power company or another power trading market. .

また、自家発電受電部１ａに設けられている自家発電装置２０の運転制御を行うための制御部２１（制御手段）は、インターネットやプライベートネットワーク等の公知の通信ネットワーク６に接続されたコンピュータで構成されて、ＰＰＳが運営管理する自家発電装置集中管理システム（以下、「本システム」と略称する。）５０との間で所定の情報についての通信可能に構成されている。   Moreover, the control part 21 (control means) for performing operation control of the private power generation device 20 provided in the private power generation / reception part 1a is configured by a computer connected to a known communication network 6 such as the Internet or a private network. Thus, it is configured to be able to communicate predetermined information with a private power generation apparatus centralized management system (hereinafter abbreviated as “this system”) 50 operated and managed by the PPS.

そして、自家発電装置２０の制御部２１は、自家発電装置２０に関する情報の他、電力メータ２３で計測された電力系統５とその間の送受電電力、ブレーカ等の保安設備２４の状態情報、ガスメータ３１で計測された自家発電装置２０及びその他のガス消費部２９でのガス消費量等の各種情報を収集して、通信ネットワーク６を介して本システム５０に送信可能に構成されている。   And the control part 21 of the private power generation device 20 is the information regarding the private power generation device 20, the power system 5 measured by the power meter 23, the transmission / reception power between them, the state information of the safety equipment 24 such as the breaker, the gas meter 31, and the like. Various types of information such as gas consumption in the private power generation apparatus 20 and other gas consumption units 29 measured in step 1 are collected and transmitted to the system 50 via the communication network 6.

更に、自家発電装置２０の制御部２１は、自家発電装置２０の発電出力を、自家発電受電部１ａにおける電力又は熱の需要状態等のエネルギ需要状態に基づいて決定された設定発電出力や定格発電出力を基準に一定に設定された設定発電出力等の、所定の定格発電出力以下の設定発電出力に制御するように構成されていると共に、例えば上記本システム５０から通信ネットワーク６を介して受信した発電出力上昇指令に基づいて、自家発電装置２０の設定発電出力を上昇させる発電出力上昇制御を実行可能に構成されている。   Further, the control unit 21 of the private power generation device 20 sets the power generation output of the private power generation device 20 to the set power generation output or rated power generation determined based on the energy demand state such as the power or heat demand state in the private power reception unit 1a. The power generation is configured to be controlled to a set power generation output that is lower than a predetermined rated power generation output, such as a set power generation output that is set to be constant with respect to the output, and received from the system 50 via the communication network 6, for example. Based on the power generation output increase command, the power generation output increase control for increasing the set power generation output of the private power generator 20 can be executed.

このように、自家発電装置２０の制御部２１が、発電出力上昇制御を実行することにより、その自家発電装置２０が設置された自家発電受電部１ａの受電電力が上記自家発電装置２０の設定上昇電力分低下することになる。即ち、電力系統５において設定上昇電力に相当する電力が調達されたことになり、ＰＰＳは、その調達電力を他の受電部１等に託送したり、自社管理発電装置１１の発電出力をその調達電力分低下させるなどに利用することができる。   Thus, when the control unit 21 of the private power generation device 20 executes the power generation output increase control, the received power of the private power reception unit 1a in which the private power generation device 20 is installed increases the setting of the private power generation device 20. The power will be reduced. That is, the power corresponding to the set increase power is procured in the power system 5, and the PPS entrusts the procured power to another power receiving unit 1 or the like, or procures the power generation output of the self-managed power generator 11 It can be used to reduce power.

更に、自家発電装置２０の制御部２１は、発電出力上昇制御において、自家発電装置２０の設定発電出力が定格発電出力よりも設定定格超電力分大きい定格超発電出力以下の範囲内で上昇させることを許容するように構成されており、例えば自家発電装置２０の設定発電出力が定格発電出力付近に設定されている場合でも、上記設定定格超電力以下の設定上昇電力分であれば、設定発電出力を、上記定格発電出力を超えて確実に上昇させることができる。   Further, the control unit 21 of the private power generator 20 increases the set power output of the private power generator 20 within the range of the rated super power output that is larger than the rated power output by the set super power output or less in the power generation output increase control. For example, even if the set power generation output of the private power generator 20 is set near the rated power output, if the set power increase is equal to or less than the set rated super power, the set power output Can be reliably increased beyond the rated power output.

更に、自家発電装置２０の制御部２１は、発電出力上昇制御において、設定発電出力が継続して定格発電出力を超える定格超運転時間を設定定格超運転時間以下に制限するように構成されており、例えば、上記定格超運転時間が過剰に継続されて、オーバーヒートや摺動部の焼付き等の問題が発生することが抑制されている。   Further, the control unit 21 of the private power generator 20 is configured to limit the rated super-operation time in which the set power generation output continuously exceeds the rated power generation output to the set rated super-operation time or less in the power generation output increase control. For example, it is suppressed that problems such as overheating and seizure of the sliding portion occur due to excessive continued operation of the rated super-operation time.

尚、その自家発電装置２０において、上記定格発電出力は、継続運転を行ってもオーバーヒートや摺動部の焼付き等の問題が発生しない発電出力の最大値として設定されており、一方、その定格発電出力を超える上記定格超発電出力は、一定の設定定格超時間を超えないかぎり上記のような問題が発生しない発電出力の最大値として設定されている。そして、上記設定定格超電力とは、上記定格超発電出力と上記定格発電出力との差として設定されている。   In the private power generator 20, the rated power output is set as the maximum value of the power output that does not cause problems such as overheating and seizure of the sliding portion even if continuous operation is performed. The rated super power output exceeding the power generation output is set as the maximum value of the power generation output that does not cause the above-described problem unless a certain set rated power super time is exceeded. The set rated super power is set as a difference between the rated super power output and the rated power output.

更に、自家発電装置２０の制御部２１は、上記のような発電出力上昇制御を実行した場合において、その発電出力上昇制御を終了してからの経過時間を計測し、その経過時間が所定の設定定格超運転間隔が経過するまでの間には、上記発電出力上昇制御の実行を禁止して、前の発電出力上昇制御を実行したことにより発生した発熱を十分に放熱し、上記経過時間が所定の設定定格超運転間隔が経過した後に、上記発電出力上昇制御の実行を許可するように構成されている。   Furthermore, the control part 21 of the private power generation device 20 measures the elapsed time after ending the power generation output increase control when the power generation output increase control as described above is executed, and the elapsed time is set to a predetermined value. Until the rated super-operation interval elapses, execution of the power generation output increase control is prohibited, heat generated by executing the previous power generation output increase control is sufficiently dissipated, and the elapsed time is predetermined. After the set rated super-operation interval elapses, execution of the power generation output increase control is permitted.

更に、自家発電装置２０の制御部２１は、上記発電出力上昇運転を行った定格超運転時間を積算した積算時間を計測し、その積算時間が所定の設定定格超運転積算時間を超えた時点以降には、オーバーヒートや摺動部の焼付き等の問題が発生する確率が高いとして、上記積算時間についてのリセット指令が入力されるまでは、発電出力上昇制御の実行を禁止するように構成されており、更に、このように積算時間が上記設定定格超運転積算時間を超えた時点に、その旨を、表示部（図示せず）に表示したり、通信ネットワーク６等を介して外部のメンテナンス事業者に送信することで、適切なメンテナンスを実施することを促すように構成されている。   Further, the control unit 21 of the private power generator 20 measures an integrated time obtained by integrating the rated super-operation time in which the power generation output increasing operation is performed, and after the time when the integrated time exceeds a predetermined set rated super-operation integrated time. Is configured to prohibit the execution of power generation output increase control until a reset command for the accumulated time is input, assuming that there is a high probability of occurrence of problems such as overheating and sliding part seizure. In addition, when the accumulated time exceeds the set rated super-operated accumulated time as described above, a message to that effect is displayed on a display unit (not shown), or an external maintenance business is performed via the communication network 6 or the like. It is configured to prompt the user to perform appropriate maintenance by transmitting to the user.

更に、制御部２１は、上記の発電出力上昇制御において設定される設定定格超時間、及び、定格超発電出力又は設定定格超電力等に関する定格超運転情報、更には、設定定格超運転間隔や設定定格超運転積算時間等に関する情報を、通信ネットワーク６を介して本システム５０に送信可能に構成されている。   Furthermore, the control unit 21 sets the rated rated super time set in the above power generation output increase control, the rated super power output related to the rated super power output or the set rated super power, and the set rated super power operation interval and setting. Information relating to the rated super-operating accumulated time and the like can be transmitted to the system 50 via the communication network 6.

上記のような制御部２１を備えた自家発電装置２０を設置していない無発電受電部１ｏにおいても、図３に示すように、通信ネットワーク６に接続されたコンピュータで構成された通信部３５が設けられ、その通信部３５は、少なくとも電力メータ２３で計測された受電量の情報を収集し、通信ネットワーク６を介して本システム５０に送信可能に構成されている。   Even in the non-power generation / reception unit 1o in which the private power generation device 20 including the control unit 21 as described above is not installed, as illustrated in FIG. 3, the communication unit 35 configured by a computer connected to the communication network 6 is provided. The communication unit 35 is configured to collect at least information on the amount of received power measured by the power meter 23 and transmit the information to the system 50 via the communication network 6.

ＰＰＳが運営管理する本システム５０は、上記のような電力小売託送を行う場合に、自社管理発電装置１１の制御部１２、自家発電受電部１ａに設けられた自家発電装置２０の制御部２１、及び、無発電受電部１ｏに設けられた通信部３５との間で、通信ネットワーク６を介して通信を行って、後述する自家発電装置２０に対する発電出力上昇指令の他、自社管理発電装置１１及び自家発電装置２０の発電計画等の演算処理及び情報通信処理可能なコンピュータで構成されている。   The system 50 operated and managed by the PPS includes the control unit 12 of the self-managed power generation device 11 and the control unit 21 of the private power generation device 20 provided in the private power generation / reception unit 1a when performing the power retail consignment as described above.

本システム５０は、図１に示すように、通信ネットワーク６を介して上記制御部１２，２１及び通信部３５等との間で通信可能な通信部５２と、各種データを格納した不揮発性の記憶部６０とを備えたコンピュータで構成されている。また、本システム５０は、所定のプログラムを実行することにより、後述する、発電計画部５４、自社管理発電装置管理部５６、自家発電装置群管理部５８として機能するように構成されている。   As shown in FIG. 1, the system 50 includes a communication unit 52 that can communicate with the control units 12, 21 and the communication unit 35 via the communication network 6, and a non-volatile memory that stores various data. It is comprised with the computer provided with the part 60. FIG. In addition, the system 50 is configured to function as a power generation planning unit 54, a self-managed power generation device management unit 56, and a private power generation device group management unit 58, which will be described later, by executing a predetermined program.

上記記憶部６０には、上述したように自家発電装置２０の発電出力上昇制御において設定される設定定格超時間、及び、定格超発電出力又は設定定格超電力等に関する定格超運転情報、更には、設定定格超運転間隔や設定定格超運転積算時間等に関する情報を、各自家発電装置２０を識別可能な状態で格納する定格超運転情報データベース６１が割り当てられている。   In the storage unit 60, as described above, the set rated super-time set in the power generation output increase control of the private power generator 20, the rated super-power output related to the rated super-power output or the set rated super-power, and the like, A rated super-operation information database 61 for storing information related to the set rated super-operating interval, the set rated super-operating accumulated time, etc. in a state where each private power generator 20 can be identified is assigned.

更に、記憶部６０には、上記定格超運転情報データベース６１以外に、受電部１の電力需要実績、自家発電装置２０の発電実績、自社発電装置１１の発電実績等の実績データを格納したデータベースや、各受電部１の属性等に関する受電部情報、自家発電装置２０の定格発電出力、発電コスト、及び、後述の応答可否情報等に関する自家発電装置情報、各受電部１とＰＰＳ及び電力会社との間で契約した電力料金等に関する電力契約情報等の基本データを格納したデータベース等が割り当てられている。   Furthermore, in addition to the rated superoperation information database 61, the storage unit 60 includes a database storing actual data such as the power demand record of the power receiving unit 1, the power generation record of the private power generator 20, and the power generation record of the in-house power generator 11. Power receiving unit information related to attributes of each power receiving unit 1, rated power generation output of private power generation device 20, power generation cost, private power generation device information related to response availability information described later, each power receiving unit 1, PPS and power company A database or the like that stores basic data such as power contract information related to power charges contracted between them is allocated.

尚、上記記憶部６０は、本システム５０との間で通信線を介して情報通信可能に構成された外部記憶装置で構成しても構わない。   The storage unit 60 may be an external storage device configured to be able to communicate information with the system 50 via a communication line.

また、上記自家発電装置群管理部５８は、上記自家発電受電部が複数あると共に、複数の前記自家発電装置２０からなる自家発電装置群Ａを集中管理するように構成され、各自家発電装置２０から受信した上記定格超運転情報等により上記定格超運転情報データベース６１等を更新したり、上記複数の自家発電装置２０から選択され発電出力上昇指令対象に対して、後述する発電出力上昇指令を実行するように構成されている。   The private power generation device group management unit 58 includes a plurality of private power generation and reception units, and is configured to centrally manage a private power generation device group A including the plurality of private power generation devices 20. The rated super-operation information database 61 and the like are updated with the rated super-operation information received from the above, or a power generation output increase command to be described later is executed for the power generation output increase command target selected from the plurality of private power generation devices 20 Is configured to do.

尚、上記自家発電装置群Ａは、例えば地域毎に分類されたもの、又は、自家発電装置２０の種類、容量、利用形態（パターン運転、調整運転）等により分類されたものとして設定することができる。   In addition, the said private power generation device group A can be set as what was classified, for example for every area, or what was classified by the kind, capacity | capacitance, usage form (pattern driving | operation, adjustment driving | operation), etc. of the private power generation device 20. it can.

本システム５０に構成された自家発電装置群管理部５８は、自家発電装置２０の夫々が備える制御２１に対して、設定発電出力を設定上昇期間において設定上昇電力分上昇させる形態で、上述した発電出力上昇制御を実行させる発電出力上昇指令を実行可能な発電出力上昇指令手段５９として機能するように構成されている。   The private power generation device group management unit 58 configured in the system 50 is configured to increase the set power generation output by the set increase power during the set increase period with respect to the control 21 provided in each of the private power generation devices 20. It is configured to function as a power generation output increase command means 59 capable of executing a power generation output increase command for executing output increase control.

そして、この発電出力上昇指令手段５９は、上記発電出力上昇指令において、上記設定上昇期間、更には上記設定上昇電力を、定格超運転情報データベース６１に格納されている定格超運転情報に基づいて決定するように構成されている。
具体的には、図６に示すように、上記発電出力上昇指令手段５９は、上記発電出力上昇指令の実行対象とする自家発電装置２０である発電出力上昇指令対象についての定格超運転情報を上記定格超運転情報データベース６１から抽出する。そして、上記発電出力上昇制御を実行させる期間である上記設定上昇期間を、その抽出した定格超運転情報である上記設定定格超時間以内に設定する。更には、上記発電出力上昇制御を実行したときの設定発電出力の上昇分の電力である上記設定上昇電力を、設定発電出力が定格超発電出力以下となる範囲内で設定するように構成されている。
よって、このように発電出力上昇指令を実行することにより、発電出力上昇指令対象の自家発電装置２０に対して、オーバーヒートや摺動部における焼付き等の問題の発生を抑制可能な設定定格超運転時間以下の上記設定上昇期間に、設定発電出力を、確実に上昇させることができる上記設定上昇電力分上昇させることができる。 The power generation output increase command means 59 determines the set increase period and further the set increase power based on the rated superoperation information stored in the rated superoperation information database 61 in the power generation output increase command. Is configured to do.
Specifically, as shown in FIG. 6, the power generation output increase command means 59 provides the rated superoperation information about the power generation output increase command target that is the private power generation apparatus 20 to be executed by the power generation output increase command. Extracted from the rated superoperation information database 61. And the said setting raise period which is a period which performs the said electric power generation output raising control is set within the said setting rated overtime which is the extracted rated superoperation information. Further, the set increase power, which is the power of the increase in the set power output when the power generation output increase control is executed, is set within a range where the set power output is less than or equal to the rated super power output. Yes.
Therefore, by executing the power generation output increase command in this way, the set rated super operation capable of suppressing the occurrence of problems such as overheating and seizure in the sliding portion with respect to the private power generation apparatus 20 subject to the power generation output increase command The set power generation output can be increased by the set increase power that can be reliably increased during the set increase period of time or less.

尚、上記設定上昇電力を設定する形態について説明を加えると、上記設定上昇電力を、定格超運転情報として格納されている設定定格超電力以下に設定することで、設定発電出力が定格超発電出力を以下となる範囲内とすることができるが、発電出力上昇制御を実行する前の設定発電出力を認識可能な場合には、上記設定上昇電力を、その設定発電出力と定格超運転情報として格納されている定格超発電出力との差分（以下、余剰電力と呼ぶ。）以下の範囲内に設定することでも、設定発電出力が定格超発電出力以下となる範囲内とすることができる。   In addition, when the form for setting the set increase power is described, the set generation output is set to the rated super power output by setting the set increase power to be equal to or lower than the set rated super power stored as the rated super operation information. However, if the set power output before executing the power generation output increase control can be recognized, the above set power increase is stored as the set power output and rated super operation information. The set power generation output can also be set within the range where the set power generation output is equal to or less than the rated super power generation output by setting it within the range of the difference from the rated super power generation output (hereinafter referred to as surplus power).

例えば、本システム５０が各自家発電装置２０の設定発電出力を常時監視することで、上記発電出力上昇指令手段５９が発電出力上昇制御を実行する前の設定発電出力を認識することができるが、自家発電装置２０の設定発電出力が一定又は予め計画されたものである場合には、その一定又は予め計画された設定発電出力を、発電出力上昇制御を実行する前の設定発電出力として認識することができる。   For example, the present system 50 constantly recognizes the set power generation output of each private power generator 20, so that the power generation output increase command means 59 can recognize the set power generation output before executing the power generation output increase control. When the set power generation output of the private power generation apparatus 20 is constant or pre-planned, the constant or pre-planned set power output is recognized as the set power generation output before the power generation output increase control is executed. Can do.

更に、上記発電出力上昇指令手段５９は、上記発電出力上昇指令において、自家発電装置群Ａの総発電出力を総設定期間に総設定電力分上昇させる形態で、上記発電出力上昇指令対象を決定するように構成されており、このように発電出力上昇指令を実行することで、電力系統５において、その総設定期間において総設定電力分の電力を調達することができる。   Further, the power generation output increase command means 59 determines the power generation output increase command target in the form of increasing the total power generation output of the private power generator group A by the total set power during the total setting period in the power generation output increase command. Thus, by executing the power generation output increase command in this way, it is possible to procure power for the total set power in the total set period in the power system 5.

即ち、図５に示すように、上記発電出力上昇指令手段５９は、先ず、上記総設定期間と上記総設定電力との入力を受け付けると共に（ステップ＃１）、定格超運転情報データベース６１から各自家発電装置２０の定格超運転情報を抽出する（ステップ＃２）。
そして、図７も参照して、上記総設定期間を横軸とし総設定電力を縦軸とした総ブロック内を、各自家発電装置２０についての、上記設定定格超時間以内に設定される設定上昇期間を横軸とし、上記設定定格超電力以下又は上記余剰電力以下に設定される上記設定上昇電力を縦軸とした個別ブロックＡ，Ｂ，Ｃ，Ｄ，Ｅ，Ｆ，Ｇを割り当てて、その割り当てられた個別ブロックＡ，Ｂ，Ｃ，Ｄ，Ｅ，Ｆ，Ｇに相当する自家発電装置２０を、発電出力上昇指令対象として決定する（ステップ＃３）。
また、自家発電装置２０の発電コストを考慮して、発電コストが小さい自家発電装置２０を優先して発電出力上昇制御を実行させる形態で、発電出力上昇対象を決定することができる。 That is, as shown in FIG. 5, the power generation output increase command means 59 first receives the input of the total set period and the total set power (step # 1), and each private output from the rated superoperation information database 61. The rated super-operation information of the power generator 20 is extracted (step # 2).
Then, referring also to FIG. 7, the setting increase set within the set rated super time for each private power generator 20 within the total block with the total set period as the horizontal axis and the total set power as the vertical axis Assign the individual blocks A, B, C, D, E, F, G with the period as the horizontal axis and the set increase power set below the set rated super power or below the surplus power as the vertical axis, The private power generator 20 corresponding to the allocated individual blocks A, B, C, D, E, F, and G is determined as a power generation output increase command target (step # 3).
Further, in consideration of the power generation cost of the private power generation apparatus 20, the power generation output increase target can be determined in a form in which the power generation output increase control is executed with priority given to the private power generation apparatus 20 with a low power generation cost.

そして、上記ステップ＃３にて決定した発電出力上昇指令対象の自家発電装置２０の制御部２１に対して、上記のように割り当てられた個別ブロッククＡ，Ｂ，Ｃ，Ｄ，Ｅ，Ｆ，Ｇにおける設定上昇期間と設定上昇電力とに関する発電出力上昇指令情報を送信することで、その発電出力上昇指令情報を受信した制御部２１に、自家発電装置２０の発電出力をその発電出力上昇指令情報から認識される設定上昇期間に設定上昇電力分上昇させる発電出力上昇制御を実行させる発電出力上昇指令を実行する（ステップ＃４）。   Then, the individual block A, B, C, D, E, F, assigned as described above to the control unit 21 of the private power generation apparatus 20 that is the target of the power generation output increase command determined in Step # 3. By transmitting the power generation output increase command information regarding the setting increase period and the set power increase in G, the power generation output of the private power generator 20 is transmitted to the control unit 21 that has received the power generation output increase command information. A power generation output increase command is executed to execute power generation output increase control for increasing the set power increase during the setting increase period recognized from (step # 4).

更に、上記発電出力上昇指令対象の各自家発電装置２０に対して上記発電出力上昇指令を実行した後に、上記発電出力上昇指令対象の各自家発電装置２０の設定発電出力に関する情報を、通信ネットワーク６を介して収集して、上記発電出力上昇指令対象の各自家発電装置２０が発電出力上昇指令情報どおりに発電出力上昇制御を実行したか否かの確認を行う（ステップ＃５）。
そして、もし、上記発電出力上昇指令対象の自家発電装置２０が、発電出力上昇指令情報のどおりの発電出力上昇制御を実行しなかったことにより、上記総設定期間の一部の期間において総設定電力の一部の電力が不足したことを確認した場合には、その期間及び電力を、再度総設定期間及び総設定電力に設定した状態で、上述したステップ＃１以降の処理を繰り返すことで、電力系統５において確実に上記総設定期間において総設定電力分の電力を調達することができる。 Further, after executing the power generation output increase command for each of the private power generation devices 20 targeted for the power generation output increase command, information regarding the set power generation output of each private power generation device 20 targeted for the power generation output increase command is transmitted to the communication network 6. To check whether or not each private power generation apparatus 20 subject to the power generation output increase command has executed the power generation output increase control according to the power generation output increase command information (step # 5).
And, if the private power generation device 20 that is the target of the power generation output increase command does not execute the power generation output increase control according to the power generation output increase command information, the total set power in a part of the total setting period When it is confirmed that a part of the power is insufficient, the processing after step # 1 described above is repeated with the period and power set to the total setting period and the total setting power again. In the system 5, it is possible to reliably procure power for the total set power during the total set period.

上記発電出力上昇指令手段５９は、図４に示すように、上記のよう発電出力上昇指令を実行することにより、後述する自家発電電力補給機能５９Ａ、受電電力削減機能５９Ｂ、及び、受電電力調整機能５９Ｃを有するように構成されている。   As shown in FIG. 4, the power generation output increase command means 59 executes a power generation output increase command as described above, whereby a self-generated power supply function 59A, a received power reduction function 59B, and a received power adjustment function, which will be described later, are performed. 59C.

自家発電電力補給機能５９Ａは、ある自家発電装置２０が停止する停止期間においてその自家発電装置２０が停止することで発電できなくなった分の停止電力分の電力を他の自家発電装置２０の設定発電出力を上昇させることにより補給する機能として構成されており、この場合、発電出力上昇指令における総設定期間及び総設定電力は、上記停止期間及び停止電力として受け付けられる。
尚、上記自家発電装置２０の停止理由が、メンテナンス等による計画的なものである場合において、上記停止期間は実際に停止する期間として設定することができるが、上記停止理由が事故等によるものである場合において、上記停止期間が不明確である場合には、上記停止期間を数時間又は数日等の適当な期間に設定して、上記自家発電装置２０が復帰するまで、その発電出力上昇指令を繰り返し実行するように構成することができる。 The self-generated power replenishment function 59 </ b> A uses the set power generation of the other private power generation devices 20 for the amount of stop power that cannot be generated by stopping the private power generation device 20 during the stop period when a certain private power generation device 20 stops. In this case, the total set period and total set power in the power generation output increase command are accepted as the stop period and stop power.
In addition, when the reason for stopping the private power generation apparatus 20 is systematic due to maintenance or the like, the stop period can be set as a period for actually stopping, but the reason for the stop is due to an accident or the like.
