Description

本発明は、夜間の系統の電力変動を火力発電機の出力で調整する際の火力発電機の運転計画を立案する火力発電機の運転計画立案装置に関する。   The present invention relates to a thermal power generator operation plan planning device for planning a thermal power generator operation plan when adjusting a power fluctuation of a system at night with an output of a thermal power generator.

電力系統に連系されている火力発電機は、夜間の電力需要の微小変動にリルタイムで追随できるように一定の調整能力を確保している。この必要な調整能力は、夜間の電力需要の数％である。   Thermal power generators linked to the electric power system have a certain adjustment capability so that they can follow the minute fluctuations in nighttime power demand in a relaxed manner. This necessary adjustment capacity is a few percent of the nighttime power demand.

夜間の電力需要の微小変動に対する追随は、火力発電機のうち特に最新式コンバインドサイクル発電ＡＣＣの出力調整（出力の急速可変）で対応するようにしている。火力発電機の１台あたりの出力調整量には制限がある。そこで、電力系統全体の出力調整量に対応できるように、複数の火力発電機を出力調整用の火力発電機として運転し、例えば、火力発電機の最低出力から定格出力の範囲の半分程度の中間出力で運転し、一定の必要調整能力を確保している。   Follow-up to minute fluctuations in power demand at night is handled by adjusting the output (rapidly variable output) of the latest combined cycle power generation ACC among thermal power generators. There is a limit to the amount of output adjustment per thermal power generator. Therefore, multiple thermal power generators are operated as thermal power generators for output adjustment so that they can correspond to the output adjustment amount of the entire power system, for example, between the lowest output of the thermal power generator and half of the rated output range. It operates with output and secures the necessary adjustment capability.

ここで、深夜の需要が最小となるときの深夜下げ代と昼間の需要が最大となるときの火力予備力とが最適なものとなるように、昼間の電力供給に必要な揚水発電所の発電電力量（揚発容量）を確保し、揚発容量が設備容量限界（揚発容量限界）を超えないように、しかも火力発電機の燃料費用が最も小さくなる条件を満たすように、深夜下げ代と火力予備力とを算出するようにしたものがある。   Here, the power generation of the pumped storage power plant necessary for daytime power supply is optimized so that the midnight reduction allowance when midnight demand is minimum and the thermal power reserve when daytime demand is maximum are optimal. The midnight reduction fee is set so that the amount of electric power (lifting capacity) is secured, the pumping capacity does not exceed the capacity limit (lifting capacity limit), and so that the fuel cost of the thermal power generator is minimized. And firepower reserve are calculated.

しかし、電力需要の昼夜格差は大きく深夜の電力需要は低いため、夜間の出力調整用の火力発電機の運転必要台数は本来少ないはずであるが、一定の調整能力を確保するために複数の火力発電機を必要としている。また、出力調整用の火力発電機は、出力増減のいずれにも対応できるように中間出力で運転しているので運転効率が悪く、環境の面からもCO2排出量が増えるので好ましくない。従って、出力調整用の火力発電機の運転台数は少ないほどよいが、出力調整用の火力発電機の運転台数が少なすぎると、夜間の電力需要の微小変動に対応することとができなくなる。また、多めに火力発電機を立ち上げた場合には、無駄な起動停止が増加することになり発電原価増やCO2排出量の増加の要因ともなる。 However, because the power demand gap is large and the power demand at night is low, the number of thermal power generators required for nighttime output adjustment should be small, but there are multiple thermal power plants to ensure a certain adjustment capacity. I need a generator. Further, the thermal power generator for adjusting the output is not preferable because it is operated at an intermediate output so as to be able to cope with any increase or decrease in output, so that the operation efficiency is poor and the CO 2 emission increases from the environmental viewpoint. Accordingly, the smaller the number of operating thermal power generators for output adjustment, the better. However, if the number of operating thermal power generators for output adjustment is too small, it will not be possible to cope with minute fluctuations in power demand at night. In addition, when a large number of thermal power generators are started up, useless start-up and stoppages increase, which causes an increase in power generation costs and an increase in CO 2 emissions.

本発明の目的は、一定の調整能力を確保しながら夜間の出力調整用の火力発電機の運転台数を適正化し、環境負荷を最小限にすることができる火力発電機の運転計画立案装置を提供することである。   An object of the present invention is to provide a thermal power generator operation planning device capable of optimizing the number of operating thermal power generators for nighttime output adjustment while minimizing environmental burden while ensuring a certain adjustment capability. It is to be.

請求項１の発明によれば、運用日の対象時間帯毎に利用可能な蓄電池の容量を予め記憶しておき、運用日の対象時間帯毎の電力需要の微少変動に対する必要調整能力と利用可能な蓄電池の容量との差分を修正必要調整能力として算定し、系統に連系される火力発電機が修正必要調整能力を満たすように火力発電機の運転計画を算定するので、利用可能な蓄電池の容量分だけ電力需要の微少変動に対する必要調整能力が軽減される。従って、必要な調整能力を確保しながら火力発電機の運転台数を適正化し、かつ環境負荷も最小限にすることができ、全体として運転効率を向上できる。   According to invention of Claim 1, the capacity | capacitance of the storage battery which can be utilized for every object time zone of an operation day is memorize | stored beforehand, and it can be used with the necessary adjustment capability with respect to the slight fluctuation | variation of the power demand for every object time zone of an operation day The difference between the capacity and the capacity of the storage battery is calculated as the required adjustment capacity, and the operation plan of the thermal power generator is calculated so that the thermal power generator connected to the grid satisfies the required adjustment capacity.

以下、本発明の実施形態を説明する。図１は本発明の実施形態に係る火力発電機の運転計画立案装置の構成図である。運転計画立案装置は、夜間の系統の電力変動を火力発電機の出力で調整する際の火力発電機の運転計画を立案するものであり、例えば、直近の１週間の火力発電機の運転計画を立案するには、入力装置１１から直近の１週間の運用日の日付ｘ及び夜間の対象時間帯ｙを演算制御装置１２に入力する。夜間の対象時間帯ｙは、例えば、電力需要が減少する２１時から翌朝の午前６時までの１時間おきの時間帯である。   Embodiments of the present invention will be described below. FIG. 1 is a configuration diagram of a thermal power generator operation plan planning apparatus according to an embodiment of the present invention. The operation planning device is a device that prepares an operation plan for a thermal power generator when adjusting the power fluctuation of the system at night with the output of the thermal power generator. For example, the operation plan for the most recent one week In order to make a plan, the input device 11 inputs the date x of the most recent operation day of the week and the night time zone y to the arithmetic and control unit 12. The night target time zone y is, for example, a time zone every other hour from 21:00 when power demand decreases to 6 am the next morning.

演算制御装置１２の想定電力需要量算定手段１３は、１週間の運用日の日付ｘ及び夜間の対象時間帯ｙが入力されると、記憶装置１４の電力需要量データベース１５に予め記憶されている電力需要量データＡを読み込み、その電力需要量データＡに基づいて、直近の１週間の各運用日における夜間の対象時間帯ｙの想定電力需要量ａを算定する。電力需要量データベース１５に予め格納されている電力需要量データＡは、例えば、過去数年間の電力需要量実績データを基に予め算出されたデータである。   The assumed power demand amount calculation means 13 of the arithmetic control device 12 is stored in advance in the power demand amount database 15 of the storage device 14 when the date x of the operation day of one week and the target time zone y at night are input. The power demand amount data A is read, and based on the power demand amount data A, the estimated power demand amount a in the target time zone y at night on each operation day of the most recent week is calculated. The power demand amount data A stored in advance in the power demand amount database 15 is data calculated in advance based on actual power demand amount data for the past several years, for example.

すなわち、季節や曜日によって夜間の対象時間帯の電力需要量が異なるので、想定電力需要量算定手段１３は、過去数年間の電力需要量実績データを基に予め算出された電力需要量データＡに基づき、直近の１週間の各運用日における夜間の対象時間帯の想定電力需要量ａを算定することになる。想定電力需要量算定手段１３で算定された想定電力需要量ａは調整能力算定手段１６に入力される。   That is, since the power demand in the target time zone at night varies depending on the season and day of the week, the assumed power demand calculation means 13 uses the power demand data A calculated in advance based on the power demand data in the past several years. Based on this, the assumed power demand amount a in the target time zone at night on each operation day of the most recent week is calculated. The assumed power demand a calculated by the assumed power demand calculating means 13 is input to the adjustment capacity calculating means 16.

調整能力算定手段１６は、想定電力需要量算定手段１３で算定された想定電力需要量ａを入力すると、記憶装置１４の電力変動率データベース１７に予め記憶されている電力変動率データＢを読み込む。電力変動率データベース１７に予め格納されている電力変動率データＢは、例えば、過去数年間の電力変動率実績データを基に予め算出されたデータであり、季節や曜日によって異なる夜間の対象時間帯の電力変動率である。   When the estimated power demand amount a calculated by the assumed power demand amount calculating means 13 is input, the adjustment capacity calculating means 16 reads the power fluctuation rate data B stored in advance in the power fluctuation rate database 17 of the storage device 14. The power fluctuation rate data B stored in advance in the power fluctuation rate database 17 is, for example, data calculated in advance based on the power fluctuation rate actual data for the past several years, and the target time zone at night that varies depending on the season and day of the week. Is the power fluctuation rate.

調整能力算定手段１６は、該当する日付ｘの対象時間帯ｙにおける電力変動率ｂを取り出し、想定電力需要量ａにその電力変動率ｂを乗算して各運用日の夜間の対象時間帯ｙにおける電力の微少変動Ｃを算定する。そして、その電力の微少変動Ｃを火力発電機の必要調整能力ｃとして修正調整能力算定手段１８に出力する。   The adjustment capability calculation means 16 takes out the power fluctuation rate b in the target time zone y of the corresponding date x, multiplies the assumed power demand amount a by the power fluctuation rate b, and in the target time zone y at night of each operation day. Calculate slight fluctuation C of electric power. Then, the slight fluctuation C of the electric power is output to the correction adjustment capacity calculation means 18 as the necessary adjustment capacity c of the thermal power generator.

次に、修正調整能力算定手段１８は、調整能力算定手段１６で算定された必要調整能力ｃを入力すると、記憶装置１４の利用可能蓄電池データベース１９に予め記憶されている利用可能蓄電池データＤを読み込み、該当する日付ｘの対象時間帯ｙにおける利用可能な蓄電池の容量ｄを取り出す。そして、火力発電機の必要調整能力ｃから利用可能な蓄電池の容量ｄを減算し、各運用日の夜間の対象時間帯ｙ毎の修正必要調整能力ｅを算定する。   Next, when the necessary adjustment capacity c calculated by the adjustment capacity calculation means 16 is input, the correction adjustment capacity calculation means 18 reads the available storage battery data D stored in advance in the available storage battery database 19 of the storage device 14. Then, the available capacity d of the storage battery in the target time zone y of the corresponding date x is taken out. And the capacity | capacitance d of the storage battery which can be utilized is subtracted from the necessary adjustment capability c of a thermal power generator, and the correction required adjustment capability e for every night time zone y of each operation day is calculated.

利用可能蓄電池データベース１９に予め記憶されている利用可能蓄電池データＤは、夜間において電力系統運用者が自由に充放電制御できる蓄電池の情報であり、例えば、蓄電池を有した需要家との契約により、電力系統運用者が利用できる蓄電池の容量が予め記憶されている。   The available storage battery data D stored in advance in the available storage battery database 19 is information on a storage battery that can be freely charged and discharged by a power system operator at night. For example, by a contract with a consumer who has a storage battery, The capacity of the storage battery that can be used by the power system operator is stored in advance.

修正調整能力算定手段１８で算定された修正必要調整能力ｅは、運転計画算定手段２０に入力される。運転計画算定手段２０は、系統に連系される火力発電機が各運用日の夜間の対象時間帯ｙ毎の修正必要調整能力ｅを満たすように、火力発電機の運転計画を算定する。運転計画算定手段２０で算定された運転計画は出力装置２１に出力される。   The correction necessary adjustment capability e calculated by the correction adjustment capability calculation means 18 is input to the operation plan calculation means 20. The operation plan calculation means 20 calculates the operation plan of the thermal power generator so that the thermal power generator linked to the system satisfies the correction necessary adjustment capability e for each target time zone y at night of each operation day. The operation plan calculated by the operation plan calculation means 20 is output to the output device 21.

この算定された運転計画は、利用可能な蓄電池の容量分だけ電力需要の微少変動に対する必要調整能力が軽減された運転計画である。従って、火力発電機の運転台数を軽減することができ、全体として電力系統の火力発電機の運転効率を向上できる。   This calculated operation plan is an operation plan in which the necessary adjustment capability for slight fluctuations in power demand is reduced by the capacity of the available storage battery. Therefore, the number of operating thermal power generators can be reduced, and the operating efficiency of the thermal power generators in the power system can be improved as a whole.

図２は、夜間のある対象時間帯ｙにおける電力需要の微少変動の一例を示すグラフである。ある対象時間帯ｙにおける電力需要は、想定電力需要量ａに対し、斜線部で示した微少変動を有している。想定電力需要量ａにその電力変動率ｂを乗算して求められる電力の微少変動Ｃは、当該対象時間帯の最大電力幅であり、この電力の微少変動Ｃが火力発電機の必要調整能力ｃとなる。   FIG. 2 is a graph showing an example of slight fluctuations in power demand in a certain target time zone y at night. The power demand in a certain target time zone y has a slight fluctuation indicated by the hatched portion with respect to the assumed power demand amount a. A slight power fluctuation C obtained by multiplying the assumed power demand a by the power fluctuation rate b is the maximum power width in the target time zone, and this small power fluctuation C is the necessary adjustment capacity c of the thermal power generator. It becomes.

調整能力算定手段１６は、該当対象時間帯ｙの想定電力需要量ａに、その電力変動率ｂを乗算して該当対象時間帯における電力の微少変動Ｃを算定する。想定電力需要量ａや電力変動率ｂは、例えば、過去の実績データであり安全を見込んだ値であるので、調整能力算定手段１６により算定される電力の微少変動Ｃは、実際の電力微少変動よりも安全側である大きめの値となる。   The adjustment capacity calculation means 16 multiplies the estimated power demand a in the target time zone y by the power fluctuation rate b to calculate a slight power fluctuation C in the target time zone. Since the assumed power demand a and the power fluctuation rate b are, for example, past performance data and values that allow for safety, the slight power fluctuation C calculated by the adjustment capability calculating means 16 is the actual small power fluctuation. It is a larger value that is safer than.

図３は、電力系統運用者が夜間に利用できる蓄電池の充電深度の一例を示すグラフである。図３では、電力需要が減少する２１時から翌朝の午前６時までの時間帯で蓄電池の充放電制御を行った場合を示している。   FIG. 3 is a graph showing an example of a charging depth of a storage battery that can be used by a power system operator at night. FIG. 3 shows a case where charge / discharge control of the storage battery is performed in a time zone from 21:00 when power demand decreases to 6 am the next morning.

通常、電力系統運用者が夜間に利用できる需要家の蓄電池は、夜間に充電し昼間に放電するように運用されている。このことから、２１時においては、蓄電池の充電深度は低となっており、翌朝の６時には充電深度は高となるように、全体として夜間に充電する特性で充放電制御が行われる。   Usually, a storage battery of a consumer that can be used at night by a power system operator is operated so as to be charged at night and discharged in the daytime. Thus, at 21:00, the charge depth of the storage battery is low, and charge / discharge control is performed with the characteristic of charging at night as a whole so that the charge depth becomes high at 6:00 the next morning.

すなわち、２１時から翌朝の６時の間において、蓄電池は電力需要量の微少変動Ｃの一部を吸収しつつ充放電を繰り返しながら全体として充電する特性で充放電制御される。   That is, from 21:00 to 6 o'clock the next morning, the storage battery is charged / discharged with the characteristic of charging as a whole while repeating charging / discharging while absorbing a part of the slight fluctuation C of the power demand.

電力需要量の微少変動Ｃの一部を吸収できる蓄電池の容量は、記憶装置１４の利用可能蓄電池データベース１９に予め利用可能な蓄電池の容量として記憶しているので、修正調整能力算定手段１８は、その利用可能な蓄電池の容量分だけ電力需要の微少変動に対する必要調整能力が軽減した修正必要調整能力を算出することになる。   Since the capacity of the storage battery that can absorb a part of the slight fluctuation C in the power demand is stored in advance in the available storage battery database 19 of the storage device 14 as the capacity of the storage battery that can be used, The corrected necessary adjustment capability is calculated by reducing the necessary adjustment capability for slight fluctuations in power demand by the capacity of the usable storage battery.

ここで、記憶装置１４の利用可能蓄電池データベース１９に予め記憶する利用可能な蓄電池の容量は、運転計画の立案の度に更新するようにすると、最新の利用可能な蓄電池の容量を使用できるので、より精度のよい運転計画を立案できる。   Here, since the capacity of the usable storage battery stored in advance in the usable storage battery database 19 of the storage device 14 is updated every time the operation plan is made, the latest available storage battery capacity can be used. A more accurate operation plan can be made.
