Definitions
- the present invention relates to an operation plan creation method, an operation plan creation program, and an operation plan creation device.
- This operation plan is, for example, a control parameter for appropriately controlling discharge from a storage battery having a limited capacity. For example, when a peak cut method for discharging the storage battery when the power demand exceeds a predetermined power value is used as the storage battery control method, this power value becomes the operation plan.
- a simulation is performed when the storage battery is operated, and power supply and demand is as expected.
- An operation plan for operating the storage battery for a day is created so that the evaluation value, which is the simulation result, becomes the best when the change occurs.
- the prediction after confirming the weather condition on that day is more accurate than the prediction of the weather on the previous day. For this reason, when the prediction on the previous day of the weather change has been missed, the operation status of the storage battery is improved by correcting the operation plan in operation based on the weather status confirmed on that day.
- a predicted deviation pattern in which the predicted value of power supply and demand deviates by a predetermined value or more and its occurrence probability are collected in advance.
- an evaluation value considering the correction of the operation plan at the time of the predicted deviation is obtained by simulation.
- the operation plan is generally corrected by re-estimating at a predetermined time or a predetermined time interval. Therefore, there is a problem that it is not possible to cope with a situation in which it is more effective to correct the operation plan before the predetermined correction time.
- the current prediction accuracy for predicting the output of power generated by natural energy is highly dependent on the accuracy of the weather forecast, and the prediction accuracy cannot be significantly improved by data that can be acquired at short time intervals during operation. For this reason, it is reasonable to revise the operation plan around noon according to the timing when the weather forecast is updated, but in this case, it is not possible to cope with output fluctuations due to sudden changes in weather conditions before noon. Become.
- the timing of weather forecasts should be used so that the remaining capacity of the storage batteries does not run out. It is desirable to correct the operation plan earlier than the combined operation plan correction.
- the present invention has an object of creating a corrected operation plan that can be detected before an influence is exerted in a situation where the effect is affected when the correction time of the operation plan is delayed.
- an operation of a power generation system including a power generation device that generates power according to an external environmental condition, and a storage battery that is charged with power from the power generation device and discharges according to power supply and demand.
- a plan creation method, an operation plan creation program, and an operation plan creation device the amount of discharge from the storage battery for a plurality of supply and demand power scenarios stored in the storage unit and indicating the transition of power supply and demand according to the external environmental conditions
- a first corrected operation plan that obtains the best amount of discharge when the operation plan is corrected at a predetermined periodic correction time, and the initial operation plan of the power storage location is corrected at a countermeasure time that has changed the periodic correction time
- the first modified operation plan is modified to the second modified operation plan at the countermeasure time.
- a scenario requiring countermeasures that need to be corrected to the plan is extracted, and the countermeasures required at the countermeasure time are extracted from the extracted scenario requiring countermeasures based on the initial operation plan and the second modified operation plan corresponding to the scenario requiring countermeasures.
- a change countermeasure scenario for correcting the initial operation plan for the scenario is classified, and an identification condition for identifying the classified change countermeasure scenario is generated and generated for the classified change countermeasure scenario based on the external environmental condition.

Abstract
Description
<運用形態の一例>
図1は、蓄電池の運転計画に基づく運用形態の一例を示す説明図である。図1において、電力系統101は、例えば、住宅やマンション、ビル、店舗、施設などの建造物に設置され、これらの建造物に電力を供給する。電力系統101は、発電装置111と、蓄電池112と、パワーコンデョショナ(Power Conditioning System、以下、「PCS」)113と、電力計114と、が接続されて構成される。電力系統101は、発電装置111からの電力により充電されるとともに電力需給に応じて放電する蓄電池112とを有する発電システムである。
図5は、運転計画作成システム103を構成するコンピュータのハードウェア構成例を示す図である。図5に示すように、コンピュータ500は、各種演算処理を実行するCPU501と、ユーザからデータの入力を受け付ける入力装置502と、モニタ503とを有する。また、コンピュータ500は、記憶媒体からプログラム等を読み取る媒体読み取り装置504と、他の装置とデータの授受を行うネットワークインターフェース装置505とを有する。また、コンピュータ500は、各種情報を一時記憶するRAM(Random Access Memory)506と、ハードディスク装置507とを有する。また、各装置501~507は、バス508に接続される。
つぎに、作成装置の機能について説明する。作成装置は、図1に示した運転計画作成システム103に含まれる、運転計画の作成機能を実現するコンピュータである。具体的には、作成装置は、太陽光発電との併用により、需要のピークカットを狙う蓄電池112の運用に関し、早期対策を実施するための運転計画修正ルールを作成するコンピュータである。例えば、1日のはじめに、最新の気象予報に基づいて作成した蓄電池112の当初運転計画を、気象予報の更新タイミングにあわせて定期修正時刻に修正することを前提に、定期修正時刻以前の各時点の状況に応じて対策を実施するための運転計画修正ルールを作成する。定期修正時刻としては、具体的には、昼頃、例えば、13時が挙げられる。
つぎに、要対策度算出部611による要対策度算出例について説明する。上述したように、要対策度算出部611は、当初運転計画を定期修正時刻より早い時間帯に修正することが必要かどうか評価するために、同一の需給シナリオに対して異なる修正時刻による2種類のシミュレーションを実行する。このシミュレーションは、与えられた需給シナリオと修正時刻において得られる効果(例えばピークカット効果、環境負荷低減効果、コスト削減効果)を見積もるシミュレーションである。ここで、修正時刻とは、早期対策時刻または定期修正時刻である。
つぎに、要対策シナリオ分類部613による要対策シナリオ分類例について説明する。要対策シナリオには、必要とされる対策が大きく異なるシナリオが混在する場合がある。例えば、当初運転計画における放電基準値に対して放電基準値を高くするような対策の場合には放電を抑える意味があり、放電基準値を低くするような対策の場合には放電を起こりやすくする意味がある。この場合、日射量や気温、需要などを用いた識別条件によって要対策シナリオ群が識別できたとしても、上記のように放電を抑える対策と起こりやすくする対策が混在していると、対策を1つに定めることができない。
つぎに、識別条件作成部614による識別条件の作成例について説明する。識別条件作成部614は、要対策シナリオ分類部613により分類された複数の早期対策対象シナリオ群の各々の早期対策対象シナリオ群について、識別条件を作成する。具体的には、識別条件作成部614は、処理対象の早期対策対象シナリオ群に属すべきシナリオか否かを判別するための判別モデルを作成する。
つぎに、出力情報作成部602による修正運転計画の作成例について説明する。出力情報作成部602は、識別条件が明らかになった要対策シナリオ群に対する修正運転計画を作成する。出力情報作成部602は、早期対策対象シナリオ群の各々に対して作成された識別条件を順々に処理対象として選択し、下記の処理を行う。
図16は、作成装置600による処理手順の一例を示すフローチャートである。作成装置600は、早期対策対象シナリオ抽出部601により、早期対策対象シナリオ抽出処理を実行し(ステップS1601)、出力情報作成部602により出力情報作成処理を実行する(ステップS1602)。
つぎに、実施の形態2について説明する。実施の形態1では、図12に示したように、作成装置600は、要対策度が抽出された要対策シナリオの修正後の最適な運転計画が当初運転計画以上であるか否かにより分類した。これに対し、実施の形態2では、作成装置600は、回帰木を構築し、構築した回帰木により要対策シナリオを分類し、回帰木を用いて識別条件を作成する。なお、実施の形態2において、要対策シナリオ分類部613、識別条件作成部614、および出力情報作成部602が実施の形態1と異なるが、それ以外は実施の形態1と同一である。したがって、実施の形態2では、要対策シナリオ分類部613、識別条件作成部614、および出力情報作成部602について説明する。まず、実施の形態2の要対策シナリオ分類部613について説明する。
要対策シナリオ分類部613は、回帰木により、早期対策時刻に利用可能なデータの値が類似し、かつ、対策(各シナリオにとって最適な修正運転計画)の違いが所定の範囲内になるような要対策シナリオのグループを求める。具体的には、例えば、要対策シナリオ分類部613は、対策を目的属性とし、早期対策時刻において利用可能なデータを説明属性とする要対策シナリオ群の回帰木を、回帰木の葉ノードにおける対策の違いが所定のしきい値以下になるように構築する。回帰木の葉ノードにおける対策の違いとしては、例えば、平均2乗誤差の値が用いられる。そして、要対策シナリオ分類部613は、対策の違いが所定の閾値以下に収めることができた葉ノードを、早期対策対象シナリオ群として選択する。そして、選択した早期対策対象シナリオ群(葉ノード)に、それぞれの群を一意に識別する群IDを割り付け、また、各早期対策対象シナリオ群に分類される需給シナリオに対して、00の早期対策項目gciに、対応する群IDを記憶する。
次に、実施の形態2の識別条件作成部614について説明する。識別条件作成部614は、回帰木2200に基づいて識別条件を作成する。具体的には、要対策シナリオ分類部613によって構築された回帰木2200における分割テストは、識別条件の候補となる。すなわち、回帰木2200は、要対策シナリオ群に対応する根ノードN0を、早期対策対象シナリオ群に対応する葉ノードL1~L4に分割するためのルールを表現する。
実施の形態2の出力情報作成部602は、識別条件作成部614によって作成された識別条件および対策の組み合わせのうち、対策不要シナリオチェックで「影響なし」の組み合わせを修正運転計画として設定する。図23の例では、出力情報作成部602は、識別条件作成テーブル2300の1~3行目のレコードを修正運転計画とし、運用システム102に出力する。
つぎに、実施の形態2にかかる作成装置600による処理手順例について説明する。上述したように、実施の形態2は、要対策シナリオ分類部613、識別条件作成部614、および出力情報作成部602が実施の形態1と異なる。したがって、処理手順についても、要対策シナリオ分類部613、識別条件作成部614、および出力情報作成部602による処理のみを説明し、それ以外は、実施の形態1と同一であるため、説明を省略する。まず、要対策シナリオ分類部613による要対策シナリオ分類処理の処理手順例について説明する。
つぎに、実施の形態3について説明する。実施の形態1,2では、あらかじめ用意された需給シナリオ群を用いたが、実施の形態3では、作成装置600が、需給シナリオ群を生成する。なお、実施の形態1,2と同一構成には同一符号を付し、その説明を省略する。
図28は、実施の形態3にかかる作成装置600の機能的構成例を示すブロック図である。図28において、作成装置600は、シナリオDB700、早期対策対象シナリオ抽出部601および出力情報作成部602のほか、記憶部2800と、受付部2801と、需給シナリオ生成部2802と、最適評価値算出部2803と、修正評価値算出部2804と、を有する。記憶部2800は、各種データが記憶されている。また、記憶部2800には、生成されたデータがCPU501により書き込まれる。また、記憶部2800に記憶されたデータは、CPU501により読み出し可能である。記憶部2800は、例えば、ハードディスク装置507により実現される。
図38は、実施の形態3にかかる作成装置600による出力情報作成処理手順の一例を示すフローチャートである。作成装置600は、需給シナリオ生成部2802により、需給シナリオ生成処理を実行する(ステップS3801)。需給シナリオ生成処理(ステップS3801)の詳細については、図39で説明する。
