Abstract
Description
本発明は、発電量に応じて電力需要を制御する技術に関する。 The present invention relates to a technique for controlling electric power demand according to the amount of power generation.
昨今、電力自由化に向けての動きが活発化している。これまでは、「発電」と「送配電」を地域の大手電力会社が担ってきたが、電力自由化後は、図８に示すように、送電・配電を行う送配電部門を独立させる「発送電分離」という考えに基づいて電力が供給される。したがって、従来のように発電側が需要に合わせて発電計画を作るのではなく、送配電側から発電側に対し、需要に合わせて給電指示が出されることになる。 In recent years, the movement toward liberalization of electricity has become active. Until now, major regional electric power companies have been responsible for "power generation" and "transmission and distribution", but after the deregulation of electric power, as shown in Fig. 8, "shipping" will make the transmission and distribution departments that transmit and distribute electricity independent. Power is supplied based on the idea of "electric power separation". Therefore, the power generation side does not make a power generation plan according to the demand as in the conventional case, but the power transmission and distribution side issues a power supply instruction to the power generation side according to the demand.
一方、従来から、原子力発電所の稼働停止以来、電力削減を目的とする装置や、電力会社のピーク時の発電能力に合わせて、需要者に節電を促すことが数多く提案されている。 On the other hand, since the shutdown of nuclear power plants, many proposals have been made to encourage consumers to save electricity according to the equipment for power reduction and the peak power generation capacity of electric power companies.
例えば、特許文献１には、デマンドレスポンス（各需要家への消費電力の削減要求に応じて、電力需要を削減する仕組み）における電力削減目標量を満たすように、制御ルールを適用して演算した場合の制御結果を、あらかじめ提示することができる電力管理支援装置が開示されている。この発明によれば、建物のフロア内における備品の配置を示すフロアレイアウトと、電力消費機器の位置を示す機器レイアウトとを結び付けた機器マッピング情報を生成し、機器マッピング情報に基づいて、各フロアを複数に区切ったエリアに属する電力消費機器を決定し、電力消費機器の制御優先度を算出する制御ルール及びパラメータに基づいて、制御結果を求め、電力消費機器のスペック、制御区分、演算ルール、電力削減目標量、フロア内の状況を示すセンシング情報に基づいて、制御結果をシミュレートし、出力することが開示されている。 For example, in Patent Document 1, a control rule is applied and calculated so as to satisfy a power reduction target amount in a demand response (a mechanism for reducing power demand in response to a power consumption reduction request to each consumer). A power management support device capable of presenting the control result of the case in advance is disclosed. According to the present invention, device mapping information is generated by linking a floor layout indicating the arrangement of equipment on the floor of a building and a device layout indicating the position of a power consuming device, and each floor is set based on the device mapping information. Determine the power consumption equipment that belongs to the area divided into multiple areas, obtain the control result based on the control rules and parameters that calculate the control priority of the power consumption equipment, and obtain the specifications, control classification, calculation rule, and power of the power consumption equipment. It is disclosed that the control result is simulated and output based on the reduction target amount and the sensing information indicating the situation in the floor.
また、特許文献２には、全体の電力状況に応じた節電の具体的な案内を提供して、人々の連帯による効果的な節電を実現する節電情報提供装置が開示されている。この発明によれば、電力使用率等の電力状況値の範囲に応じ、電気製品ごとの節電必要度をいくつかのレベルで表す等したデータとして用意し、それを用い、電力会社からの電力使用状況データ等として提供される地域や社会全体の電力状況に応じた節電の具体的な案内として、電力状況値に応じた節電必要度を電気製品のアイコン表示態様で具体的に表示する。これにより、ユーザは、多種類の電器製品を用いていても容易に節電が実行できるとしている。 Further, Patent Document 2 discloses a power saving information providing device that provides specific guidance for power saving according to the overall power situation and realizes effective power saving by solidarity of people. According to the present invention, according to the range of power status values such as the power usage rate, data is prepared as data representing the necessity of power saving for each electric product at several levels, and the data is used to use power from a power company. As specific guidance for power saving according to the power status of the region or society as a whole provided as status data, the necessity of power saving according to the power status value is concretely displayed in the icon display mode of the electric product. As a result, the user can easily save power even when using various types of electric appliances.
また、本出願の発明者らも、特許文献３において、節電行動を促すために、ユーザのクレジットカード等の利用履歴からユーザの行動履歴を記録し、カード会社のサーバがユーザの家庭の節電量とユーザの取ったカードでの購入行動とを評価し、当該評価に応じてユーザに付与するインセンティブを決定する節電行動誘発システムを提案している。 Further, in Patent Document 3, the inventors of the present application also record the user's behavior history from the usage history of the user's credit card or the like in order to promote the power saving behavior, and the server of the card company saves power in the user's home. We are proposing a power saving behavior induction system that evaluates the purchase behavior of the card taken by the user and determines the incentive to be given to the user according to the evaluation.
上記の特許文献に記載の方法は、いずれも節電を促すもので、電力需要を抑制方向に制御する技術であるが、この電力需要の制御においては、電力需要予測が必要である。図７は、電力需要予測のイメージを表したものである。例えば、夏場においては、図７（ａ）に示すように、日の出５時頃から人々の活動の開始とともに電力の使用が増え、気温の上昇とともに１４〜１５時頃に冷房等の電力使用のピークを迎える。一方、冬場においては、図７（ｂ）に示すように、日の出６時頃から人々の活動の開始とともに電力の使用が増え、日の入り・気温の低下とともに照明や暖房等の電気の使用が増えてくる。特に、冬場は、夏場に比べて日の入りが早いので、帰宅時間帯と家庭での使用が重なる１７〜１９時頃に電力使用のピークを迎えることが多い。冬場は夏場に比べて、昼と夜で電力使用の差が小さいため、電力需要は、１日を通じて比較的フラットなカーブとなる。 All of the methods described in the above patent documents promote power saving and are techniques for controlling power demand in a restraining direction, but power demand forecasting is necessary for controlling power demand. FIG. 7 shows an image of the power demand forecast. For example, in the summer, as shown in Fig. 7 (a), the use of electric power increases with the start of people's activities from around 5 o'clock at sunrise, and the peak of electric power use such as air conditioning around 14:00 to 15:00 as the temperature rises. Welcome to. On the other hand, in winter, as shown in Fig. 7 (b), the use of electricity increases as people start their activities around 6 o'clock at sunrise, and the use of electricity such as lighting and heating increases as the sun sets and the temperature drops. come. In particular, in winter, the sunset is earlier than in summer, so the peak of electricity usage is often reached around 17:00 to 19:00, when the time of returning home and the use at home overlap. In winter, the difference in electricity usage between day and night is smaller than in summer, so electricity demand has a relatively flat curve throughout the day.
このように、電力需要の制御においては、季節や時間帯ごとの電力需要予測に合わせた供給と需要の調整が必要となる。しかし、電力需要の予測に合わせて発電量（給電量）を指示するとしても、実際の需要と乖離することがある。図７では、例えば１４時の時点で、予定した給電指示量（一点鎖線で示す）と最新需要予測(点線で占めす）とを比較すると、夏場・冬場ともハッチングで示す領域が需要不足となり、逆に、夏場で黒塗りの領域が給電不足となることを示している。したがって、給電指示量（発電指示量）と需要予測とのギャップをできるかぎり小さくすることが必要となる。 In this way, in controlling the power demand, it is necessary to adjust the supply and demand according to the power demand forecast for each season and time zone. However, even if the amount of power generation (power supply amount) is instructed according to the forecast of electric power demand, it may deviate from the actual demand. In FIG. 7, for example, at 14:00, when the planned power supply instruction amount (indicated by the alternate long and short dash line) and the latest demand forecast (occupied by the dotted line) are compared, the area indicated by hatching becomes insufficient in both summer and winter. On the contrary, it shows that the black-painted area becomes insufficient in power supply in the summer. Therefore, it is necessary to make the gap between the power supply instruction amount (power generation instruction amount) and the demand forecast as small as possible.
このギャップを極小化する仕組みとして「実同時同量」の考え方に基づいて、各電力事業者に対応義務を課してきた。実同時同量の考え方は、実際に供給（発電）した量と自社の顧客が実際に消費した量の一致を求めるものである。各電力事業者は事前の需要予測に基づいて発電計画を立てているが、時々刻々の実需要の変化に合わせて、発電側の運転を調整することで実同時同量を達成する努力を行ってきた。すなわち、発電と小売が一体となって同時同量を達成してきた。 As a mechanism to minimize this gap, each electric power company has been obliged to respond based on the concept of "actual simultaneous equal amount". The idea of the same amount at the same time is to find the match between the amount actually supplied (generated) and the amount actually consumed by the company's customers. Each electric power company makes a power generation plan based on the demand forecast in advance, but makes efforts to achieve the same amount at the same time by adjusting the operation on the power generation side according to the change of actual demand from moment to moment. I came. That is, power generation and retail have been integrated to achieve the same amount at the same time.
一方、電力自由化に関する制度改革の中で、需給制御の考え方が「実同時同量」から「計画値同時同量」に改められることとなった。計画値同時同量では、発電側と小売側のそれぞれが、送配電事業者に提出する事前に計画した量と実際の量の一致が求められることとなる。つまり、発電側の同時同量は「事前に計画した発電量どおりに発電できたか」を問われ、小売側の同時同量は「事前に計画した需要量どおりの需要であったか」が問われる。なお、実際の量と計画値とのギャップについては、送配電事業者が責任を持って調整することとなる。計画値同時同量では、発電側と小売側は別々に同時同量義務を負うことから、小売事業者は予測値と実際の量とのギャップを発電機の運転で調整することはできず、需要のみによって調整することが求められる。すなわち、小売事業者は「精度の高い需要予測を行うこと」と「予測どおりに顧客に電力を消費させること」が求められることとなる。 On the other hand, in the system reform related to electricity liberalization, the concept of supply and demand control has been changed from "actual simultaneous equal amount" to "planned simultaneous equal amount". With the same planned value at the same time, the power generation side and the retail side are required to match the pre-planned amount submitted to the power transmission and distribution operator with the actual amount. In other words, the simultaneous equal amount on the power generation side is asked "whether the power generation was possible according to the pre-planned power generation amount", and the simultaneous equal amount on the retail side is asked "whether the demand was according to the pre-planned demand amount". The power transmission and distribution operator will be responsible for adjusting the gap between the actual amount and the planned value. With the planned simultaneous equal amount, the power generation side and the retail side are obliged to have the same amount separately, so the retailer cannot adjust the gap between the predicted value and the actual amount by operating the generator. It is required to adjust only by demand. In other words, retailers are required to "make highly accurate demand forecasts" and "make customers consume electricity as predicted."
したがって、本発明では、上記のような課題に鑑み、従来の電力の予測需要量に合わせて需要を抑制的に調整することに加えて、予測需要量に合わせて需要を促進する仕組みも提供し、抑制と促進のダブルで電力需要を制御する、ダブルデマンドレスポンスの制御を可能とすることを目的とする。 Therefore, in view of the above problems, the present invention provides a mechanism for promoting demand according to the predicted demand amount in addition to restrainingly adjusting the demand according to the conventional predicted demand amount of electric power. The purpose is to enable control of double demand response, which controls power demand by double suppression and promotion.

図１は、本発明の実施形態に係る電力需要制御システムの機能構成を示す図である。図示するように、電力需要制御システム１００（以下、本システムと呼ぶ）は、新電力会社又は送配電事業者のシステムであって、需要家のシステム又は制御機器(以下、需要家２００と呼ぶ）と接続され、以下の機能部を備えている。すなわち、本システムは、機能部として、需要予測手段１０１と、実測値計測手段１０２と、変動検知手段１０３と、非即時需要要請手段１０４と、需要家応答受信手段１０５と、需要家評価手段１０６とを備え、また、その機能を実現するために必要なデータベース（ＤＢ）として、実測値ＤＢ１０と、需要予測ＤＢ１１１と、需要家情報ＤＢ１１２とを備える。
(Functional configuration)
FIG. 1 is a diagram showing a functional configuration of a power demand control system according to an embodiment of the present invention. As shown in the figure, the electric power demand control system 100 (hereinafter referred to as this system) is a system of a new electric power company or a power transmission and distribution business operator, and is a consumer system or control device (hereinafter referred to as a consumer 200). It is connected to and has the following functional parts. That is, as a functional unit, this system includes a demand forecasting means 101, an actually measured value measuring means 102, a fluctuation detecting means 103, a non-immediate demand requesting means 104, a consumer response receiving means 105, and a consumer evaluation means 106. As a database (DB) necessary for realizing the function, the actual measurement value DB 10, the demand forecast DB 111, and the consumer information DB 112 are provided.
本システムは、需要家の需要を「即時電力需要」と「非即時電力需要」に分けて管理し、送配電事業者は、管轄する電力需要が計画需要量に満たない場合に、管内の需要家に対して電力消費を要請し（消費を促し）、要請を受けた需要家に電力消費要請に対して、準備していた「非即時電力需要」を基にその要請に応えてもらい、要請に応えてくれた需要家にはインセンティブを与えるものである。「非即時電力需要」（「非即時需要」ともいう）とは、即時に電力は必要としないが、いずれ、例えば３０分から数時間以内といった近々の時間に、電力が必要となることが分かっている電力需要、又は電力が節約できることが期待できる電力需要のことである。非即時需要要請には、電力需要が給電量を下回ると予測される場合に電力消費を促す要請と、電力需要が給電量を上回ると予測される場合に電力消費を抑制する要請とがある。 This system manages the demand of consumers by dividing it into "immediate power demand" and "non-immediate power demand", and the power transmission and distribution company manages the demand within the jurisdiction when the power demand under its jurisdiction is less than the planned demand. Request power consumption from the house (promote consumption), and ask the requested consumer to respond to the power consumption request based on the prepared "non-immediate power demand". It gives incentives to consumers who respond to the demand. "Non-immediate power demand" (also referred to as "non-immediate demand") does not require immediate power, but it has been found that power will be needed in the near future, for example, within 30 minutes to several hours. It is the power demand that exists, or the power demand that can be expected to save power. Non-immediate demand requests include a request for encouraging power consumption when the power demand is predicted to be lower than the power supply amount, and a request for suppressing power consumption when the power demand is predicted to exceed the power supply amount.
非即時電力需要には、例えば、一般家庭では、食洗機や洗濯機の運転、お風呂の湯沸し等の他、今後普及する家庭用蓄電池への蓄電等も考えられる。大口需要家の非即時電力需要には、例えば、セントラル暖房・冷房のための蓄電、データセンタにおける保留ジョブの実行の制御、広告事業者における照明設備（プロジェクションマッピングによる広告投影等）、工場の稼働率の制御（工場での在庫用部品の製造等）が考えられる。 Non-immediate power demand may include, for example, in general households, operation of dishwashers and washing machines, boiling water in baths, and storage in household storage batteries that will become widespread in the future. Non-immediate power demand of large consumers includes, for example, electricity storage for central heating and cooling, control of execution of pending jobs in data centers, lighting equipment in advertising companies (advertising projection by projection mapping, etc.), factory operation. Control of the rate (manufacturing of parts for inventory at the factory, etc.) can be considered.
需要予測手段１０１は、所定時間後の電力需要を予測する。すなわち、少なくとも、過去の電力需要の実績を日ごと時間帯ごとに格納した実測値ＤＢ１１０と、外部から取得する温度、湿度等の気象データとから、当日の時間帯ごとの電力需要を予測する。更に必要であれば、カレンダー情報や電力を多量に消費するイベントのデータを加えて、当日の時間帯ごとの電力需要を予測する。予測された結果は、需要予測ＤＢ１１１に格納される。実測値ＤＢ１１０には、実測値計測手段１０２が需要家２００から取得し、計測した実際の電力使用量が常に格納される。 The demand forecasting means 101 predicts the electric power demand after a predetermined time. That is, at least, the electric power demand for each time zone of the day is predicted from the actually measured value DB 110 that stores the actual results of the past electric power demand for each time zone every day and the meteorological data such as temperature and humidity acquired from the outside. Furthermore, if necessary, calendar information and data on events that consume a large amount of power are added to forecast power demand for each time zone of the day. The predicted result is stored in the demand forecast DB 111. In the measured value DB 110, the actual power consumption amount acquired by the measured value measuring means 102 from the consumer 200 and measured is always stored.
変動検知手段１０３は、需要予測手段１０１が予測した予測値と、実測値計測手段１０２が計測した実測値との変動値を検知する。具体的には、実測値ＤＢ１１０に格納された最新の実測値と需要予測ＤＢ１１１の最新の予測値とを常に比較し、予測値と実測値の変動を検知する。変動検知手段１０３は、予測値に対して実測値が下回ると判断したときは、非即時需要要請手段１０４を介して、電力の使用要請（非即時使用要請）を需要家２００（需要家のシステム）に発信する。逆に、予測値に対して需要が上回ると判断したときは、需要家２００に対して節電要請（非即時抑制要請）を発信したり、給電量増加指示を発信したりする。ここで、非即時使用要請と非即時抑制要請を合わせて非即時需要要請と呼ぶが、非即時抑制要請に応えるための節電方法については、既存の技術を利用するものとし、ここでは説明を省略する。 The fluctuation detecting means 103 detects the fluctuation value between the predicted value predicted by the demand forecasting means 101 and the measured value measured by the measured value measuring means 102. Specifically, the latest measured value stored in the measured value DB 110 and the latest predicted value of the demand forecast DB 111 are constantly compared, and the fluctuation between the predicted value and the measured value is detected. When the fluctuation detecting means 103 determines that the measured value is lower than the predicted value, the fluctuation detecting means 103 makes a power use request (non-immediate use request) to the consumer 200 (customer's system) via the non-immediate demand request means 104. ). On the contrary, when it is determined that the demand exceeds the predicted value, a power saving request (non-immediate suppression request) is sent to the consumer 200, or a power supply amount increase instruction is sent. Here, the non-immediate use request and the non-immediate suppression request are collectively referred to as a non-immediate demand request, but the existing technology is used for the power saving method for responding to the non-immediate suppression request, and the description is omitted here. To do.
非即時需要要請手段１０４は、非即時需要要請に応えることが可能な需要家の情報を格納した需要家情報ＤＢ１１２から、需要家のシステムのあて先やその他必要な情報を取得し、使用要請又は抑制要請を送信する。需要家のシステムは、企業等の事業者においては、事業者内の装置の電力制御システムであり、一般家庭においては、ＨＥＭＳ（Home Energy Management System）等の住宅用エネルギー管理機器である。なお、需要家側になんらかの方法で使用要請又は抑制要請を受信する手段を備えていれば、ＨＥＭＳがなくとも需要家が手動で機器を操作してもよい。非即時需要要請処理の詳細については後述する。 The non-immediate demand request means 104 acquires the destination of the customer's system and other necessary information from the customer information DB 112 that stores the information of the customer who can respond to the non-immediate demand request, and requests or suppresses the use. Send the request. The consumer system is a power control system for the equipment in the business operator such as a company, and is a residential energy management device such as HEMS (Home Energy Management System) in a general household. If the consumer side is provided with a means for receiving the usage request or the suppression request by some method, the consumer may manually operate the device without the HEMS. Details of the non-immediate demand request processing will be described later.
需要家応答受信手段１０５は、非即時需要要請に対する需要家２００からの応答を受信し、その応答に含まれる需要の増加量又は減少量を需要予測手段１０１に入力するとともに、その応答（レスポンス）に対する評価を行う需要家評価手段１０６を実行させる。需要予測手段１０１は入力された情報を基に需要予測を更新する。なお、ＨＥＭＳで増減量を取得して通知するなど、需要家の応答は需要の増減結果を通知するだけであってもよい。 The consumer response receiving means 105 receives the response from the consumer 200 to the non-immediate demand request, inputs the increase or decrease amount of the demand included in the response to the demand forecasting means 101, and the response (response). The consumer evaluation means 106 for evaluating the above is executed. The demand forecasting means 101 updates the demand forecast based on the input information. In addition, the response of the consumer may be only to notify the result of increase / decrease in demand, such as acquiring and notifying the amount of increase / decrease in HEMS.
需要家評価手段１０６は、非即時需要要請に対する応答を、需要家ごとに評価する。この評価は、要請に対する応答時間、貢献量等に基づいて、貢献ポイントを算出することで行われる。算出された貢献ポイントに基づいて、需要家にインセンティブ（例えば、電気料金の割引等）が提供される。評価方法の詳細については後述する。 The consumer evaluation means 106 evaluates the response to the non-immediate demand request for each customer. This evaluation is performed by calculating contribution points based on the response time to the request, the amount of contribution, and the like. Based on the calculated contribution points, incentives (for example, discounts on electricity charges) are provided to consumers. The details of the evaluation method will be described later.
（非即時需要リスト）
図２、図３は、本発明の実施形態に係る非即時需要リストを示す図である。非即時需要リストとは、各需要家の電力を必要とする機器（需要対象の機器）ごとに、その機器や設備を保有しているか否かの情報（省略可）と、非即時使用要請に応えることが可能か否かを示す情報と、要請に応えることが可能な場合はその機器の予想需要量（Ｋｗ／ｈｒ）とを含むテーブルである。非即時需要リストには、一般家庭向けと大口需要家向けとがある。
(Non-immediate demand list)
2 and 3 are diagrams showing a non-immediate demand list according to an embodiment of the present invention. The non-immediate demand list is for each consumer's power-requiring device (demand target device), information on whether or not the device or equipment is owned (optional), and a non-immediate use request. It is a table including information indicating whether or not it is possible to respond, and if it is possible to respond to the request, the expected demand amount (Kw / hr) of the device. The non-immediate demand list includes households and large consumers.
図２は、一般家庭向けの非即時需要リストの一例を示す図である。この図で示すように、例えば、家庭内に蓄電可能な補助電池がある場合は、その蓄電池を要請のあった時間帯に充電することで、非即時使用要請に応えることができる。また、エアコンが省エネモード等で出力を抑制している場合は、その出力を要請の時間帯だけ復帰させることで要請に応えることができる。また、電気自動車（ＥＶ）の充電も非即時使用要請に応えることができる好適な機器である。その他の機器（例えば、給湯設備、食洗機、乾燥機、炊飯器、融雪機）も、時と場合によっては要請に応えることが可能なので、非即時需要リストに加え、ＨＥＭＳ等の制御において利用可能とする。なお、図では省略しているが、可否の情報には、対応可能な時間帯の情報も含まれるものとする。 FIG. 2 is a diagram showing an example of a non-immediate demand list for general households. As shown in this figure, for example, when there is an auxiliary battery that can store electricity in the home, it is possible to respond to the non-immediate use request by charging the storage battery at the requested time zone. Further, when the air conditioner suppresses the output in the energy saving mode or the like, the request can be met by returning the output only during the requested time zone. In addition, charging of an electric vehicle (EV) is also a suitable device capable of responding to a request for non-immediate use. Other equipment (for example, hot water supply equipment, dishwasher, dryer, rice cooker, snowmelter) can also meet the request in some cases, so it is used in the control of HEMS etc. in addition to the non-immediate demand list. Make it possible. Although omitted in the figure, the availability information includes information on available time zones.
図３は、大口需要家向けの非即時需要リストの一例を示す図である。この図では、需要家ごとに、需要対象となる設備を保有しているか否かの情報と、保有している場合は非即時使用要請に応えることが可能か否かの情報と、要請に応えることが可能な場合は、その予測需要量（Ｋｗ／ｈｒ）とがリストに含まれることを示している。要請に対する可否の情報には、対応可能な時間帯の情報も含まれるものは同様である。非即時需要リストは、需要家のシステムはもちろん、本システムの需要家情報ＤＢ１１２にも登録される。 FIG. 3 is a diagram showing an example of a non-immediate demand list for large consumers. In this figure, for each customer, information on whether or not they own the equipment to be demanded, and if so, information on whether or not it is possible to respond to a non-immediate use request, and respond to the request. If possible, it indicates that the projected demand (Kw / hr) is included in the list. The same applies to the information on whether or not a request can be made, including information on available time zones. The non-immediate demand list is registered not only in the customer system but also in the customer information DB 112 of this system.
需要対象には、例えば、セントラル暖房・冷房のための蓄電設備、データセンタの制御設備（コンピュータによる計算に多くの電力を消費するデータセンタにおける保留ジョブの実行の制御）、広告のための照明設備（照明に多くの電力を消費する広告事業者におけるプロジェクションマッピングによる広告投影等）、工場の稼働率の制御設備（工場での在庫用部品の製造等の制御）が考えられる。また、水力発電のための揚水設備にも多量の電力を使用するので、水力発電所も広い意味で大口需要家と考えることができる。また、水力発電以外の発電所であってもその他発電用に電力を必要とする設備（例えば、原子力廃棄物の再処理施設、メタンハイドレートの採取設備等）であれば、需要対象に含めることができる。すなわち、発電所やその関連施設も需要家として機能させることができる。なお、原子力発電所も発電量の調整のために揚水発電を用いているが、そのこととは逆である。 Demand targets include, for example, power storage equipment for central heating and cooling, data center control equipment (control of pending job execution in data centers that consume a lot of power for computer calculations), and lighting equipment for advertising. (Advertisement projection by projection mapping in an advertising company that consumes a lot of power for lighting, etc.) and factory operation rate control equipment (control of manufacturing of inventory parts at the factory, etc.) can be considered. In addition, since a large amount of electric power is used for pumping equipment for hydroelectric power generation, hydroelectric power plants can be considered as large consumers in a broad sense. In addition, even if it is a power plant other than hydroelectric power generation, if it is other equipment that requires electric power for power generation (for example, nuclear waste reprocessing facility, methane hydrate extraction facility, etc.), it should be included in the demand target. Can be done. That is, the power plant and its related facilities can also function as consumers. Nuclear power plants also use pumped storage power generation to adjust the amount of power generation, but the opposite is true.
一般家庭では様々な電気機器があり、変動も激しいため、非即時需要リストの個別の機器の情報の需要家情報ＤＢ１１２への登録は省略してもよい。しかし、大口需要家の設備は、貢献量への影響が大きく、対象設備も限られ、あらかじめ電力使用契約で知ることができるため、需要家情報ＤＢ１１２の登録に設備の情報を含めることが好ましい。また、図示は省略するが、節電要請である非即時抑制要請が発せられたときのための「非即時抑制リスト」も作成してもよい。 Since there are various electric devices in a general household and the fluctuations are drastic, the registration of the information of the individual devices in the non-immediate demand list in the consumer information DB 112 may be omitted. However, since the equipment of a large consumer has a large influence on the amount of contribution, the target equipment is limited, and can be known in advance by the power usage contract, it is preferable to include the equipment information in the registration of the customer information DB 112. Further, although not shown, a "non-immediate suppression list" may be created for when a non-immediate suppression request, which is a power saving request, is issued.
（非即時需要要請処理）
図４は、本発明の実施形態に係る非即時需要要請処理のフローを示す図である。この処理は、非即時需要要請手段１０４が行う処理である。以下では、電力需要を促進するための非即時使用要請の場合について説明するが、電力需要を抑制(節電）するための非即時抑制要請の場合も基本的には同様である。
(Non-immediate demand request processing)
FIG. 4 is a diagram showing a flow of non-immediate demand request processing according to the embodiment of the present invention. This process is a process performed by the non-immediate demand request means 104. In the following, the case of the non-immediate use request for promoting the power demand will be described, but the case of the non-immediate suppression request for suppressing the power demand (power saving) is basically the same.
非即時使用要請では、まずステップＳ１０において、所定時間後（例えば３０分後）に需要不足の見込みがあるかどうかを常に判断する。需要不足の見込みが発生した場合は、ステップＳ１１に移り、需要不足量に応じて、現時点で要請に応えてくれそうな需要家を選択する。このとき、需要家情報ＤＢ１１２の非即時需要リストが参照される。必要に応じて、過去の実績からみて応答率が高い需要家を優先して要請を送信するようにしてもよい。また、現時点では要請に応えてくれそうもない需要家であっても予備候補として選択するようにしてもよい。要請を受けられるか否かは実際には刻々と変化するからである。予備候補は、需要家情報の内容によって順位付けされ、要請に応えてくれた需要家だけでは需要が不足する場合に、その順位付けに従って、非即時需要要請が発信される。また、上記の所定時間以上前に調整が必要であることが判明した場合は、需要家に対して「非即時需要」の応答準備要請を通知してもよい。そのようにすることで、必要な時にタイミングよく要請に応じてもらうことが可能となる。 In the non-immediate use request, first, in step S10, it is always determined whether or not there is a possibility of lack of demand after a predetermined time (for example, 30 minutes later). When a demand shortage is expected, the process proceeds to step S11, and a consumer who is likely to meet the request at the present time is selected according to the demand shortage amount. At this time, the non-immediate demand list of the consumer information DB 112 is referred to. If necessary, the request may be sent with priority given to the customer who has a high response rate in view of the past performance. In addition, even consumers who are unlikely to respond to the request at this time may be selected as preliminary candidates. This is because whether or not a request can be received actually changes from moment to moment. The preliminary candidates are ranked according to the content of the customer information, and when the demand is insufficient only by the customers who have responded to the request, a non-immediate demand request is sent according to the ranking. Further, if it is found that the adjustment is necessary before the above-mentioned predetermined time or more, the consumer may be notified of the response preparation request of "non-immediate demand". By doing so, it becomes possible to have the request responded in a timely manner when necessary.
次に、非即時使用要請のステップＳ１２では、選択した需要家のシステムに使用要請（電力消費要請）を発信し、需要家からのレスポンス（応答）を待つ。需要家のシステムからレスポンスがあった場合は（ステップＳ１３：Ｙ）、ステップＳ１４において、その需要家のレスポンス情報を記録する。レスポンス情報には応答時間、レスポンス回数、使用要請に対する貢献量（Ｋｗ／ｈｒ）の見込みが含まれる。ここでステップＳ１３，Ｓ１４の処理は、ステップＳ１５において、使用要請を発した時間から所定時間が経過するまで（例えばステップＳ１０の所定時間の１０分前まで）続けられる。なお、所定時間内であれば、同じ需要家から何度でもレスポンスを受け取ってもよいし、前回のレスポンスの更新や取り消しも受け付けてもよい。 Next, in step S12 of the non-immediate use request, a use request (power consumption request) is sent to the system of the selected consumer, and a response (response) from the consumer is awaited. When there is a response from the consumer's system (step S13: Y), the response information of the consumer is recorded in step S14. The response information includes the response time, the number of responses, and the estimated contribution amount (Kw / hr) to the usage request. Here, the processes of steps S13 and S14 are continued in step S15 from the time when the request for use is issued until a predetermined time elapses (for example, 10 minutes before the predetermined time in step S10). You may receive the response from the same customer as many times as you like within the predetermined time, and you may also accept the update or cancellation of the previous response.
最後に、非即時使用要請のステップＳ１６では、レスポンスのあった需要家の要請に対する貢献量の合計を算出し、需要予測手段１０１に入力し、需要予測に反映させる。その後は、ステップＳ１０に戻り、以後同様の処理を繰り返す。 Finally, in step S16 of the non-immediate use request, the total amount of contribution to the request of the customer who responded is calculated, input to the demand forecasting means 101, and reflected in the demand forecast. After that, the process returns to step S10, and the same process is repeated thereafter.
（需要家評価）
図５は、本発明の実施形態に係る需要家ランクテーブルの一例を示す図である。需要家ランクテーブルとは、需要家評価手段１０６が行う需要家を評価するためのテーブルであり、月別又は季節ごとに定義される。需要家ランクテーブルには、図示するように、応答時間、応答時間ランク、対応可能時間帯、難易度ランクが含まれる。例えば、要請があってから５分以内に応答があった場合は、応答時間ランクは最も高い１となる。
(Customer evaluation)
FIG. 5 is a diagram showing an example of a consumer rank table according to an embodiment of the present invention. The consumer rank table is a table for evaluating consumers performed by the consumer evaluation means 106, and is defined monthly or seasonally. The consumer rank table includes response time, response time rank, available time zone, and difficulty rank, as shown. For example, if there is a response within 5 minutes after the request is made, the response time rank is 1, which is the highest.
また、難易度ランクは、要請に対応可能な時間が一般的に難しい時間であればあるほど高くなる。例えば、２２時〜６時等の時間帯は、比較的対応がしやすいと考えられるので難易度ランクは低いが、１０〜１８時等の時間帯は、対応が難しいと考えられるので難易度ランクを高く設定する。もちろん、難易度ランクは、時期によって変動するので、需要家ランクテーブルは時期ごとに設定される。すなわち、同じ対応可能時間帯でも時期によって難易度ランクは変動する。図５では、夏場と冬場の例を示している。なお、対応可能時間帯の代わりに、実際に要請に対応した時間帯を使って、難易度ランクを決定してもよい。応答時間、応答時間ランク、対応可能時間帯、難易度ランクを総合的に判断して需要家の貢献ポイントが算出される。 In addition, the difficulty rank becomes higher as the time available for responding to a request is generally difficult. For example, the difficulty rank is low because it is considered that it is relatively easy to respond during the time zone from 22:00 to 6:00, but the difficulty rank is considered to be difficult during the time zone such as 10 to 18:00. Is set high. Of course, the difficulty rank changes depending on the time, so the consumer rank table is set for each time. That is, the difficulty rank changes depending on the time even in the same available time zone. FIG. 5 shows an example of summer and winter. In addition, instead of the available time zone, the difficulty level rank may be determined by using the time zone actually corresponding to the request. The contribution points of consumers are calculated by comprehensively judging the response time, response time rank, available time zone, and difficulty level rank.
図６は、本発明の実施形態に係る需要家評価テーブルの一例を示す図である。需要家評価テーブルは、前述した需要家ランクテーブルに基づいて、需要家評価手段１０６が需要家を評価したテーブルである。需要家評価テーブルは、需要家情報ＤＢ１１２に格納され、需要家ＩＤごとに、需要家応答受信手段１０５が受信した、要請に対する貢献回数（又は応答回数）、実際の貢献量（Ｋｗ／ｈｒ）、平均応答時間（秒）含まれ、これらの値から所定のルールで貢献ポイントが算出される。貢献ポイントは、その値によって高・中・低などで分類してもよい。需要家評価手段１０６によって、一定期間の間で算出された貢献ポイントに基づいて、各需要家に対するインセンティブが決定される。なお、需要家評価テーブルは、図示するように、大口需要家と一般家庭を分けて管理し、別々の評価基準を用いてもよい。 FIG. 6 is a diagram showing an example of a consumer evaluation table according to an embodiment of the present invention. The consumer evaluation table is a table in which the consumer evaluation means 106 evaluates a customer based on the above-mentioned customer rank table. The customer evaluation table is stored in the customer information DB 112, and for each customer ID, the number of contributions (or the number of responses) to the request received by the customer response receiving means 105, the actual contribution amount (Kw / hr), and the actual contribution amount (Kw / hr). The average response time (seconds) is included, and contribution points are calculated from these values according to a predetermined rule. Contribution points may be classified into high, medium, low, etc. according to their values. The consumer valuation means 106 determines incentives for each consumer based on the contribution points calculated over a period of time. As shown in the figure, the consumer evaluation table may be managed separately for large consumers and general households, and different evaluation criteria may be used.
このようにすることで、要請に対する貢献回数、貢献量及び平均応答時間に基づいて、貢献ポイントを算出するので、要請に対してより実効性のある応答をした需要家ほどインセンティブが高くなる。また、大口需要家と一般家庭で需要対象となる設備又は機器を登録することで、より有用性、実効性が高くなる。 By doing so, the contribution points are calculated based on the number of contributions to the request, the amount of contribution, and the average response time, so that the customer who responds more effectively to the request has a higher incentive. In addition, by registering the equipment or equipment that is the target of demand for large consumers and general households, the usefulness and effectiveness will be higher.
以上説明した本システムの機能構成やデータ構成は、あくまで一例であり、一つの機能ブロック（データベース及び機能処理部）を分割したり、複数の機能ブロックをまとめて一つの機能ブロックとして構成したりしてもよい。各機能処理部は、サーバ装置等に内蔵されたＣＰＵ（Central Processing Unit）が、ＲＯＭ（Read Only Memory）、フラッシュメモリ、ＳＳＤ(Solid State Drive)、ハードディスク等の記憶装置に格納されたコンピュータ・プログラムを読み出し、ＣＰＵにより実行されたコンピュータ・プログラムによって実現される。すなわち、各機能処理部は、このコンピュータ・プログラムが、記憶装置に格納されたデータベース（ＤＢ;Data Base)やメモリ上の記憶領域からテーブル等の必要なデータを読み書きし、場合によっては、関連するハードウェア（例えば、入出力装置、表示装置、通信インターフェース装置）を制御することによって実現される。また、本発明の実施形態におけるデータベース（ＤＢ）は、商用データベースであってよいが、単なるテーブルやファイルの集合体をも意味し、データベースの内部構造自体は問わないものとする。 The functional configuration and data configuration of this system described above are just examples, and one functional block (database and functional processing unit) may be divided, or multiple functional blocks may be combined into one functional block. You may. In each function processing unit, a CPU (Central Processing Unit) built into a server device or the like is a computer program in which a memory device such as a ROM (Read Only Memory), a flash memory, an SSD (Solid State Drive), or a hard disk is stored. Is read and realized by a computer program executed by the CPU. That is, each function processing unit reads and writes necessary data such as a table from a database (DB; Data Base) stored in a storage device or a storage area in a memory by this computer program, and is related in some cases. It is realized by controlling the hardware (for example, input / output device, display device, communication interface device). Further, the database (DB) in the embodiment of the present invention may be a commercial database, but it also means a mere collection of tables and files, and the internal structure of the database itself does not matter.
（実施形態の効果）
本システムによれば、従来のように、電力の供給量に合わせて需要を抑制的に調整すること(非即時抑制要請）に加えて、供給量に合わせて需要を促進する仕組み（非即時使用要請）を提供することができる。こうすることで、電力需要のダブルデマンドレスポンスの制御が可能となり、同時同量の計画が可能となる。
(Effect of embodiment)
According to this system, in addition to the conventional method of restraining demand adjustment according to the power supply amount (non-immediate suppression request), a mechanism to promote demand according to the supply amount (non-immediate use). Request) can be provided. By doing so, it is possible to control the double demand response of the power demand, and it is possible to plan the same amount at the same time.
また、需要家評価手段を備え、要請に応えてくれた需要家にインセンティブを与えることで、上記の要請の実効性を高めることができる。また、需要家評価手段は、需要家が保有する設備ごとの要請に対する応答の可否と予測需要量を格納する非即時需要リストを備え、要請に対する貢献回数、貢献量及び平均応答時間に基づいて、貢献ポイントを算出するので、要請に対してより実効性のある応答をした需要家ほどインセンティブが高くなる。また、大口需要家と一般家庭で需要対象となる設備又は機器を登録することで、より有用性、実効性が高くなる。また、発電所やその関連施設も、その設備を登録することで、電力を使う側の大口需要家として含めることができる。 In addition, the effectiveness of the above request can be enhanced by providing a consumer evaluation means and giving an incentive to the customer who responded to the request. In addition, the consumer evaluation means includes a non-immediate demand list that stores the availability of response to the request for each facility owned by the customer and the predicted demand amount, and is based on the number of contributions to the request, the contribution amount, and the average response time. Since the contribution points are calculated, the incentive is higher for the consumer who responds more effectively to the request.
