Abstract

If a notification that relates to demand response and that originates from a server (11) outside of the home indicates an advance warning, this control device (2) switches the control mode from a normal mode to a demand response mode and sets the time period corresponding to the demand response as a specific time period. If the control mode is the demand response mode, then, in a time period prior to the specified time period, the control device (2) controls the charging of a storage battery (7) such that the remaining power in the storage battery (7) reaches a predetermined required power amount. Then, during the specified time period, the control device (2) controls the multiple apparatuses (5) on the basis of a reduction level set in advance by the user, and, once the specified time period has elapsed, switches the control mode from the demand response mode to the normal mode.

Description

制御装置、機器制御システム、機器制御方法及びプログラムControl device, device control system, device control method and program
　本発明は、制御装置、機器制御システム、機器制御方法及びプログラムに関する。 The present invention relates to a control device, a device control system, a device control method, and a program.
　近年、電力の安定供給を図る観点から、デマンドレスポンス（ＤＲ：Demand Response）の事業化が進展している。このデマンドレスポンスとは、電力需要バランスを維持するために需要家に対して需要抑制や需要シフトを促すインセンティブ制度である。 In recent years, commercialization of demand response (DR) has been progressing from the viewpoint of stable power supply. This demand response is an incentive system that encourages consumers to suppress demand or shift demand in order to maintain a power demand balance.
　デマンドレスポンスはおおまかに、電気料金ベースのものとインセンティブベースのものとに分けられる。電気料金ベースのデマンドレスポンスは、電気料金メニュー（時間帯別料金、クリティカルピーク料金、リアルタイム料金など）を通じて需要家のピークシフトを促すものである。また、インセンティブベースのデマンドレスポンスは、需要家に需要抑制の対価を支払うことによってピークシフトやピークカットを促すものである。 Demand response can be roughly divided into those based on electricity charges and those based on incentives. Demand response based on electricity charges encourages consumers to shift their peaks through electricity price menus (hourly charges, critical peak charges, real-time charges, etc.). Incentive-based demand response encourages peak shifts and peak cuts by paying the demand for demand suppression to consumers.
　このようなデマンドレスポンスに関連した先行技術として、例えば、特許文献１には、需要家の好みに合わせた機器制御を行うことを目的としたＤＲ対応策提案装置が開示されている。このＤＲ対応策提案装置は、複数の機器に関連する複数の機器制御ルールを格納するルールデータベースと、機器制御ルールの順位に関する情報を記憶するルール順位履歴データベースとを備え、ＤＲサーバからの消費電力削減要求を受信すると、順位の高い機器制御ルールを優先的に選択し、選択した機器制御ルールを実行することで、対応する機器の動作を制御する。 As a prior art related to such demand response, for example, Patent Literature 1 discloses a DR countermeasure proposal device for the purpose of performing device control in accordance with consumer preferences. The DR countermeasure proposal device includes a rule database that stores a plurality of device control rules related to a plurality of devices, and a rule order history database that stores information on the order of the device control rules, and includes power consumption from the DR server. When the reduction request is received, the device control rule with the highest priority is preferentially selected, and the operation of the corresponding device is controlled by executing the selected device control rule.

　前記充放電制御部は、前記特定時間帯より前の時間帯において、前記蓄電池の残量が予め定めた必要電力量に達するように前記蓄電池の充電を制御し、
　前記機器制御部は、前記特定時間帯の間、予めユーザにより設定された抑制レベルに基づいて前記複数の機器を制御し、
　前記モード切替部は、前記特定時間帯が過ぎると前記制御モードを前記デマンドレスポンスモードから前記通常モードに切り替える。 In order to achieve the above object, a control device according to the present invention provides:
A demand response receiving unit that receives a notification about a demand response from a server outside the house;
A charge / discharge control unit for controlling charge / discharge of the storage battery;
A device control unit for controlling a plurality of devices;

And the data used at the time of execution of these programs are memorized.
　抑制レベル設定データ２２０は、ユーザにより予め設定された抑制レベルを示すデータである。抑制レベルとは、ＤＲ（Demand Response：デマンドレスポンス）に対応する時間帯において、商用電源８から供給される電力量、即ち、電力会社等から購入する電力量（買電力量）を抑制する強度（抑制強度）を示す指標である。図３に示すように、本実施形態では、抑制レベルは、０～４の数値で示され、この数値が大きい程、抑制強度は大きくなる。ユーザは、所望の抑制強度に対応する抑制レベルを操作端末３を操作して制御装置２に設定することができる。 The suppression level setting data 220 is data indicating the suppression level preset by the user.

It is an index indicating (inhibition strength). As shown in FIG. 3, in the present embodiment, the suppression level is indicated by a numerical value of 0 to 4, and the higher the numerical value, the higher the suppression strength. The user can set the suppression level corresponding to the desired suppression strength in the control device 2 by operating the operation terminal 3.
　制御部２３は、ＣＰＵ（Central Processing Unit）、ＲＯＭ（Read Only Memory）、ＲＡＭ（Random Access Memory）等（何れも図示せず）を含んで構成され、制御装置２を統括制御する。図４に示すように、制御部２３は、本発明特有の機能として、ユーザインタフェース処理部２３０と、ＤＲ受付部２３１と、モード切替部２３２と、特定時間帯設定部２３３と、充放電制御部２３４と、機器制御部２３５と、を備える。これらの構成部の機能は、ＣＰＵ等が、データ記憶部２２に記憶されているプログラムを実行することで実現される。 The control unit 23 includes a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), and the like (all not shown) and controls the control device 2 in an integrated manner.

The functions of these components are realized by a CPU or the like executing a program stored in the data storage unit 22.
　ユーザインタフェース処理部２３０は、操作端末３を介したユーザインタフェース処理を行う。即ち、ユーザインタフェース処理部２３０は、ユーザからの操作を操作端末３及び無線通信部２１を介して受け付け、受け付けた操作の内容に応じた処理を行う。また、ユーザインタフェース処理部２３０は、ユーザに提示するための情報（例えば、監視画面データや各種の操作画面データ）を無線通信部２１を介して操作端末３に送信し、かかる情報を操作端末３に表示させる処理を行う。 The user interface processing unit 230 performs user interface processing via the operation terminal 3.

Process to be displayed on.
　ＤＲ（Demand Response）受付部２３１は、広域通信部２０を介してサーバ１１と通信を行い、サーバ１１からデマンドレスポンスに関する通知（ＤＲ通知）を受け付ける。サーバ１１は、電力会社や電力会社に委託された機関等で管理されるサーバ・コンピュータである。電力会社等は、ＤＲ通知により、ＣＰＰ（Critical Peak Pricing）やＰＴＲ（Peak Time Rebate）等の情報を需要家（ここでは、家屋Ｈの居住者であるユーザ）に通知することができる。 A DR (Demand Response) receiving unit 231 communicates with the server 11 via the wide area communication unit 20 and receives a notification (DR notification) regarding a demand response from the server 11. The server 11 is a server computer managed by an electric power company or an organization entrusted to the electric power company. An electric power company or the like can notify consumers (here, a user who is a resident of the house H) of information such as CPP (Critical Peak Pricing) and PTR (Peak Time Rebate) by DR notification.
　ＣＰＰとは、ＤＲに対応する時間帯（ピーク時間帯や指定する時間帯）の電気料金単価が高騰することを示す。ピーク時間帯とは、１日のうちで電力需要が最も多くなる時間帯をいう。また、ＰＴＲとは、ＤＲに対応する時間帯に消費電力量を削減すると、その削減量に応じて払い戻しを行うことを示す。 CPP indicates that the unit price of electricity charges in the time zone corresponding to DR (peak time zone or specified time zone) soars. The peak time zone refers to a time zone during which power demand is highest during a day. In addition, PTR indicates that when the amount of power consumption is reduced in a time zone corresponding to DR, a refund is performed according to the reduction amount.
　ＤＲ通知には、ＤＲの種別（ＣＰＰやＰＴＲ等）を示す情報（ＤＲ種別）と、通知の種別を示す情報（通知種別）とが含まれる。本実施形態では、通知種別として、「予告通知」、「決定通知」及び「取消通知」の３つがある。「予告通知」とは、ＤＲ種別で示されるＤＲの実施を予告するための通知である。「決定通知」とは、予告したＤＲが確実に実施されることの通知である。この「決定通知」は、予告したＤＲに対応する時間帯の開始時刻から１時間程度前にサーバ１１から送信される。「取消通知」は、予告したＤＲの実施を取り消した（キャンセルした）ことの通知であり、当該ＤＲに対応する時間帯より前に通知される。また、ＤＲ通知には、必要に応じて当該ＤＲに対応する時間を指定する情報も含まれる。 The DR notification includes information (DR type) indicating the type of DR (CPP, PTR, etc.) and information (notification type) indicating the type of notification. In this embodiment, there are three types of notification: “notice notification”, “decision notification”, and “cancellation notification”. The “notice notice” is a notice for notifying the implementation of the DR indicated by the DR type. The “determination notification” is a notification that the predicted DR is surely performed. This “determination notification” is transmitted from the server 11 about one hour before the start time of the time zone corresponding to the notified DR. The “cancellation notification” is a notification that the implementation of the predicted DR has been canceled (cancelled), and is notified before the time zone corresponding to the DR. The DR notification also includes information for designating a time corresponding to the DR as necessary.
　ＤＲ受付部２３１は、サーバ１１からのＤＲ通知を広域通信部２０を介して受信すると、受信したＤＲ通知をＲＡＭ又はデータ記憶部２２に保存する。 When the DR reception unit 231 receives the DR notification from the server 11 via the wide area communication unit 20, the DR reception unit 231 stores the received DR notification in the RAM or the data storage unit 22.
　モード切替部２３２は、ＤＲ受付部２３１が受け付けたＤＲ通知が予告通知である場合、制御モードを通常モードからＤＲモードに切り替える。また、モード切替部２３２は、ＤＲ受付部２３１が受け付けたＤＲ通知が取消通知である場合、制御モードをＤＲモードから通常モードに切り替える。さらに、モード切替部２３２は、ＤＲモード時において、ＤＲに対応する時間帯の開始時刻から予め定めた時間前（本実施形態では、１０分前）になってもサーバ１１から決定通知が来ない場合、制御モードをＤＲモードから通常モードに切り替える。 The mode switching unit 232 switches the control mode from the normal mode to the DR mode when the DR notification received by the DR receiving unit 231 is a notice notification. In addition, when the DR notification received by the DR reception unit 231 is a cancellation notification, the mode switching unit 232 switches the control mode from the DR mode to the normal mode. Furthermore, in the DR mode, the mode switching unit 232 does not receive a determination notification from the server 11 even if it is a predetermined time before the start time of the time zone corresponding to the DR (in this embodiment, 10 minutes before). In this case, the control mode is switched from the DR mode to the normal mode.
　特定時間帯設定部２３３は、予め定めたタイミングで、ＤＲに対応する時間帯を特定時間帯として設定する。本実施形態では、制御モードが通常モードからＤＲモードに切り替わった際に特定時間帯設定部２３３は、ＤＲに対応する時間帯（ピーク時間帯や、あるいは、ＤＲ通知により指定された時間帯）を特定時間帯として設定する。 The specific time zone setting unit 233 sets the time zone corresponding to the DR as the specific time zone at a predetermined timing. In the present embodiment, when the control mode is switched from the normal mode to the DR mode, the specific time zone setting unit 233 sets the time zone corresponding to the DR (the peak time zone or the time zone specified by the DR notification). Set as a specific time zone.
　充放電制御部２３４は、無線通信部２１及びＰＣＳ６を介して蓄電池７の充電及び放電を制御する。制御モードがＤＲモードである場合、充放電制御部２３４は、特定時間帯設定部２３３により設定された特定時間帯より前の時間帯（準備時間帯）において、蓄電池７の残量が予め定めた必要電力量に達するように蓄電池７の充電を制御する。この場合、 充放電制御部２３４は、準備時間帯の中で電気料金単価が最も安くなる時間帯（あるいは、電気代が最も安くなる時間帯）に蓄電池７が充電されるようにＰＣＳ６を制御する。必要電力量は、例えば３ｋＷｈに初期設定されている。ユーザは、操作端末３を操作して必要電力量の設定値を変更することができる。 The charge / discharge control unit 234 controls charging and discharging of the storage battery 7 via the wireless communication unit 21 and the PCS 6. When the control mode is the DR mode, the charge / discharge control unit 234 determines the remaining amount of the storage battery 7 in a time zone (preparation time zone) before the specific time zone set by the specific time zone setting unit 233. The charging of the storage battery 7 is controlled so as to reach the required power amount. In this case, the battery charging / discharging control unit 234 controls the PCS 6 so that the storage battery 7 is charged in a time zone in which the unit price of electricity is the cheapest in the preparation time zone (or in a time zone in which the electricity bill is cheapest). . The required power amount is initially set to 3 kWh, for example. The user can change the setting value of the required power amount by operating the operation terminal 3.
　電気料金単価（電気料金の時間帯別単価）や時間帯別の電気代に関するデータ（料金データ）は、ユーザにより操作端末３を介して制御装置２に設定され、データ記憶部２２に保存されているものとする。あるいは、制御装置２が、インターネット等の広域ネットワークに接続される場合では、制御装置２は、電力会社や電力会社に委託された機関等で管理されるサーバからデータ通信により料金データを取得してもよい。 The unit price of electricity charges (unit price of electricity charges by time zone) and the data (charge data) related to electricity charges by time zone are set in the control device 2 by the user via the operation terminal 3 and stored in the data storage unit 22. It shall be. Alternatively, when the control device 2 is connected to a wide area network such as the Internet, the control device 2 acquires charge data by data communication from a server managed by an electric power company or an organization entrusted to the electric power company. Also good.
　また、充放電制御部２３４は、制御モードがＤＲモードである場合、特定時間帯に入ると蓄電池７に放電を開始させる。 Further, when the control mode is the DR mode, the charge / discharge control unit 234 causes the storage battery 7 to start discharging when the specific time zone is entered.
　機器制御部２３５は、無線通信部２１を介して各機器５の動作を制御する。制御モードがＤＲモードである場合、機器制御部２３５は、特定時間帯の間、抑制レベル設定データ２２０に設定された抑制レベルに基づいて各機器５を制御する。この場合、より詳細には、機器制御部２３５は、抑制レベルに基づいて各機器５の消費電力を低下させるための制御（抑制制御）の内容（抑制制御内容）を判別する。本実施形態では、抑制制御内容は、抑制レベルが示す値に応じて予め機器５毎に定められている。図５に、各機器５の抑制制御内容の一例を示す。なお、抑制レベルが０の場合、機器制御部２３５は、抑制制御を行わない。 The device control unit 235 controls the operation of each device 5 via the wireless communication unit 21. When the control mode is the DR mode, the device control unit 235 controls each device 5 based on the suppression level set in the suppression level setting data 220 during the specific time period. In this case, more specifically, the device control unit 235 determines the content (suppression control content) of control (suppression control) for reducing the power consumption of each device 5 based on the suppression level. In the present embodiment, the suppression control content is predetermined for each device 5 according to the value indicated by the suppression level. In FIG. 5, an example of the suppression control content of each apparatus 5 is shown. If the suppression level is 0, the device control unit 235 does not perform suppression control.
　図５において、“ＸＸ％低下”とは、消費電力を現状のＸＸ％まで低下させることを意味する。“冷房時：＋１℃”とは、冷房運転時の設定温度（目標温度）を１℃上げることを意味する。また、“暖房時：－１℃”とは、暖房運転時の設定温度（目標温度）を１℃下げることを意味する。 In FIG. 5, “XX% reduction” means to reduce the power consumption to the current XX%. “Cooling: + 1 ° C.” means that the set temperature (target temperature) during cooling operation is increased by 1 ° C. “Heating: −1 ° C.” means that the set temperature (target temperature) during heating operation is lowered by 1 ° C.
　機器制御部２３５は、機器５毎に判別した抑制制御内容を示す制御コマンドを生成し、生成した制御コマンドを無線通信部２１を介して各機器５に送信する。かかる制御コマンドを受信した機器５は、受信した制御コマンドに応じた動作を行う。 The device control unit 235 generates a control command indicating the suppression control content determined for each device 5, and transmits the generated control command to each device 5 via the wireless communication unit 21. The device 5 that has received such a control command performs an operation according to the received control command.
　図６及び図７は、制御装置２の制御部２３によって実行されるＤＲ対応処理の手順を示すフローチャートである。このＤＲ対応処理は、予め定めた周期で（例えば、１０分毎に）繰り返し実行される。 6 and 7 are flowcharts showing the procedure of the DR handling process executed by the control unit 23 of the control device 2. This DR handling process is repeatedly executed at a predetermined cycle (for example, every 10 minutes).
　制御部２３は、サーバ１１からのＤＲ通知を広域通信部２０を介して受信すると（ステップＳ１０１；ＹＥＳ）、受信したＤＲ通知をＲＡＭ又はデータ記憶部２２に保存するとともに、受信したＤＲ通知が予告通知であるか否かを判別する（ステップＳ１０２）。ＤＲ通知を受信しなかった場合（ステップＳ１０１；ＮＯ）、制御部２３はステップ１１２の処理に進む。 When receiving the DR notification from the server 11 via the wide area communication unit 20 (step S101; YES), the control unit 23 stores the received DR notification in the RAM or the data storage unit 22, and the received DR notification is notified in advance. It is determined whether it is a notification (step S102). When the DR notification is not received (step S101; NO), the control unit 23 proceeds to the process of step 112.
　受信したＤＲ通知が予告通知でない場合（ステップＳ１０２；ＮＯ）、制御部２３はステップＳ１０８の処理に進む。一方、受信したＤＲ通知が予告通知である場合（ステップＳ１０２；ＹＥＳ）、制御部２３は、ユーザからＤＲへの参加が承諾されている否かを判別する（ステップＳ１０３）。ユーザによるＤＲへの参加の承諾有無を示すデータ（承諾有無設定データ）は、データ記憶部２２に記憶されている。ユーザは、操作端末３を操作して、ＤＲへの参加の承諾有無を承諾有無設定データに予め設定することができる。なお、初期状態では、承諾有無設定データは「承諾有り」に設定されている。 When the received DR notification is not the advance notification (step S102; NO), the control unit 23 proceeds to the process of step S108. On the other hand, when the received DR notification is the advance notification (step S102; YES), the control unit 23 determines whether or not the user is permitted to participate in the DR (step S103). Data indicating whether or not the user is permitted to participate in DR (acceptance setting data) is stored in the data storage unit 22. The user can operate the operation terminal 3 to set in advance the approval / disapproval setting data in the approval / disapproval setting data. In the initial state, the consent presence / absence setting data is set to “with consent”.
　ユーザからＤＲへの参加が承諾されていない場合（ステップＳ１０３；ＮＯ）、制御部２３はステップＳ１１２の処理に進む。一方、ユーザからＤＲへの参加が承諾されている場合（ステップＳ１０３；ＹＥＳ）、制御部２３は、制御モードを通常モードからＤＲモードに切り替え（ステップＳ１０４）、決定フラグをオフにする（ステップＳ１０５）。決定フラグとは、予告通知の受信後に決定通知を受けたか否かを示すフラグである。 If the user has not been accepted to participate in DR (step S103; NO), the control unit 23 proceeds to the process of step S112. On the other hand, when the user is permitted to participate in DR (step S103; YES), the control unit 23 switches the control mode from the normal mode to the DR mode (step S104), and turns off the determination flag (step S105). ). The decision flag is a flag indicating whether or not a decision notification has been received after the notification of the advance notice is received.
　また、制御部２３は、ＤＲに対応する時間帯を特定時間帯として設定する（ステップＳ１０６）。そして、制御部２３は、上述した準備時間帯において、蓄電池７の残量が必要電力量に達するように蓄電池７の充電を制御する処理（充電制御処理）を開始し（ステップＳ１０７）、ステップＳ１１２の処理に進む。なお、制御部２３は、制御モードをＤＲモードに切り替えると、必ずしも直ちに蓄電池７の充電をＰＣＳ６に指示するのではなく、上述したように、電気料金の時間帯別単価が最も安くなる時間帯（あるいは、電気代が最も安くなる時間帯）に蓄電池７が充電されるようにＰＣＳ６を制御する。 Further, the control unit 23 sets a time zone corresponding to DR as a specific time zone (step S106). And the control part 23 starts the process (charge control process) which controls charge of the storage battery 7 so that the residual amount of the storage battery 7 reaches required electric energy in the preparation time slot | zone mentioned above (step S107), and step S112 Proceed to the process. Note that when the control unit 23 switches the control mode to the DR mode, the control unit 23 does not always immediately instruct the PCS 6 to charge the storage battery 7 but, as described above, the time period in which the unit price of the electricity price is the lowest ( Alternatively, the PCS 6 is controlled so that the storage battery 7 is charged in the time zone when the electricity bill is the cheapest.
　受信したＤＲ通知が取消通知である場合（ステップＳ１０８；ＹＥＳ）、制御部２３は、制御モードをＤＲモードから通常モードに切り替える（ステップＳ１０９）。また、制御部２３は、ステップＳ１０７で開始した蓄電池７の充電制御処理を中止し（ステップＳ１１０）、ステップＳ１１２の処理に進む。 When the received DR notification is a cancellation notification (step S108; YES), the control unit 23 switches the control mode from the DR mode to the normal mode (step S109). Moreover, the control part 23 stops the charge control process of the storage battery 7 started by step S107 (step S110), and progresses to the process of step S112.
　受信したＤＲ通知が取消通知でない、即ち決定通知である場合（ステップＳ１０８；ＮＯ）、制御部２３は、決定フラグをオンにし（ステップＳ１１１）、ステップＳ１１２の処理に進む。 When the received DR notification is not a cancellation notification, that is, a determination notification (step S108; NO), the control unit 23 turns on the determination flag (step S111), and proceeds to the process of step S112.
　ステップＳ１１２では、制御部２３は、制御モードがＤＲモードであるか否かを判別する。ＤＲモードでない場合（ステップＳ１１２；ＮＯ）、制御部２３は、本周期におけるＤＲ対応処理を終了する。一方、制御モードがＤＲモードである場合（ステップＳ１１２；ＹＥＳ）、制御部２３は、特定時間帯に入っているか否か、即ち、現時刻が特定時間帯に属するか否かを判別する（ステップＳ１１３）。 In step S112, the control unit 23 determines whether or not the control mode is the DR mode. When not in the DR mode (step S112; NO), the control unit 23 ends the DR handling process in this cycle. On the other hand, when the control mode is the DR mode (step S112; YES), the control unit 23 determines whether or not the specific time zone is entered, that is, whether or not the current time belongs to the specific time zone (step S112). S113).
　特定時間帯に入っている場合（ステップＳ１１３；ＹＥＳ）、制御部２３は、上述した抑制制御を実行し（ステップＳ１１４）、本周期におけるＤＲ対応処理を終了する。 When it is in the specific time zone (step S113; YES), the control unit 23 executes the suppression control described above (step S114), and ends the DR handling process in this cycle.
　特定時間帯に入ってはいないが、開始前１０分以内であり、且つ、決定フラグがオフの場合（ステップＳ１１５；ＹＥＳ）、制御部２３は、制御モードをＤＲモードから通常モードに切り替え（ステップＳ１１６）、本周期におけるＤＲ対応処理を終了する。ステップＳ１１５でＮＯと判別した場合、制御部２３は、本周期におけるＤＲ対応処理を終了する。 If it is not within the specific time zone but is within 10 minutes before the start and the determination flag is OFF (step S115; YES), the control unit 23 switches the control mode from the DR mode to the normal mode (step S115). S116), the DR handling process in this cycle is terminated. When it determines with NO by step S115, the control part 23 complete | finishes the DR corresponding | compatible process in this period.
　以上説明したように、本発明の実施形態１に係る機器制御システム１では、制御装置２は、ＤＲ通知を受けた際、ユーザにより予め設定された抑制レベルに基づいて各機器５に対する抑制制御を行う。このため、家屋Ｈの居住者であるユーザの生活シーンに合わせた抑制制御を行うことができる。したがって、ＤＲ通知に対応した特定時間帯における買電力量の抑制をユーザの快適性をなるべく損なわずに実現することが可能となる。 As described above, in the device control system 1 according to the first embodiment of the present invention, when the control device 2 receives the DR notification, the control device 2 performs the suppression control on each device 5 based on the suppression level set in advance by the user. Do. For this reason, the suppression control according to the life scene of the user who is a resident of the house H can be performed. Therefore, it is possible to realize the suppression of the amount of power purchased in a specific time zone corresponding to the DR notification without impairing the user's comfort as much as possible.
　また、制御装置２は、特定時間帯の開始前に蓄電池７が必要電力量を蓄えられるように予め準備時間帯に充電を行っておき、特定時間帯に入ると蓄電池７に放電させるため、特定時間帯における買電力量の抑制をより図れる。さらに、制御装置２は、準備時間帯の中で電気料金単価が最も安くなる時間帯（あるいは、電気代が最も安くなる時間帯）に蓄電池７が充電されるようにＰＣＳ６を制御するため、蓄電池７の充電にかかる料金を抑えることができる。 In addition, the control device 2 charges in the preparation time zone in advance so that the storage battery 7 can store the required amount of power before the start of the specific time zone, and discharges the storage battery 7 when entering the specific time zone. The amount of power purchased in the time zone can be further reduced. Furthermore, since the control device 2 controls the PCS 6 so that the storage battery 7 is charged in a time zone in which the unit price of electricity is the lowest during the preparation time zone (or a time zone in which the electricity bill is the lowest), the storage battery The charge for charging 7 can be reduced.
（実施形態２）
　続いて、本発明の実施形態２について説明する。なお、以下の説明において、実施形態１と共通する構成要素等については、同一の符号を付し、その説明を省略する。 (Embodiment 2)
Subsequently, Embodiment 2 of the present invention will be described. In the following description, components and the like that are common to the first embodiment are denoted by the same reference numerals, and description thereof is omitted.
　本実施形態の制御装置２が備える制御部２３には、図８に示すように、実施形態１の制御部２３と比較し、消費電力量予測部２３６と、必要電力量決定部２３７とが追加されている。 As shown in FIG. 8, the control unit 23 included in the control device 2 of the present embodiment includes a power consumption amount prediction unit 236 and a required power amount determination unit 237 compared to the control unit 23 of the first embodiment. Has been.
　消費電力量予測部２３６は、特定時間帯の間、抑制レベルに応じて各機器５を制御した場合の消費電力量を予測する。より詳細には、消費電力量予測部２３６は、準備時間帯において充放電制御部２３４によって蓄電池７の充電を制御する処理が開始される前に、現在設定されてる抑制レベルに応じて抑制制御を行った場合の消費電力量を予測する。その際、消費電力量予測部２３６は、データ記憶部２２に保存されている、過去に実行した抑制制御時における消費電力量の履歴データ、各機器５の性能を示すデータや現在の動作状態等を勘案して予測を行う。 The power consumption prediction unit 236 predicts the power consumption when each device 5 is controlled according to the suppression level during a specific time period. More specifically, the power consumption prediction unit 236 performs suppression control according to the currently set suppression level before the process of controlling the charging of the storage battery 7 by the charge / discharge control unit 234 is started in the preparation time period. Predict the amount of power consumed when you do so. At that time, the power consumption amount prediction unit 236 stores the history data of the power consumption amount during the suppression control executed in the past, the data indicating the performance of each device 5, the current operation state, etc. To make a prediction.
　必要電力量決定部２３７は、消費電力量予測部２３６により予測された消費電力量に基づいて必要電力量を決定する。例えば、予測された消費電力量に予め定めた係数（例えば、１．２）を乗じることで必要電力量を決定してもよい。あるいは、基準電力量（例えば、２ｋＷｈ）に、予測された消費電力量と予め定めた閾値との比較により得られた補正値（正又は負）を加算することで、必要電力量を決定してもよい。例えば、予測された消費電力量が上限閾値を超えている場合には、補正値として＋１ｋＷｈを加算し、予測された消費電力量が下限閾値より少ない場合には、補正値として－１ｋＷｈを加算する。 The required power amount determination unit 237 determines the required power amount based on the power consumption amount predicted by the power consumption amount prediction unit 236. For example, the required power amount may be determined by multiplying the predicted power consumption amount by a predetermined coefficient (for example, 1.2). Alternatively, the required power amount is determined by adding a correction value (positive or negative) obtained by comparing the predicted power consumption and a predetermined threshold to a reference power amount (for example, 2 kWh). Also good. For example, when the predicted power consumption exceeds the upper limit threshold, +1 kWh is added as a correction value, and when the predicted power consumption is less than the lower limit threshold, −1 kWh is added as a correction value. .
　以上説明したように、本実施形態の機器制御システム１によれば、制御装置２は、特定時間帯の開始前に蓄電池７が蓄えておくべき必要電力量を、予測した特定時間帯における消費電力量に基づいて決定する。このため、蓄電池７に特定時間帯で必要となる適切な電力量を効率的に蓄えておくことが可能となる。 As described above, according to the device control system 1 of the present embodiment, the control device 2 determines the power consumption that the storage battery 7 should store before the start of the specific time zone, and the power consumption in the predicted specific time zone. Determine based on quantity. For this reason, it becomes possible to efficiently store an appropriate amount of power required in the specific time zone in the storage battery 7.
　なお、消費電力量予測部２３６は、制御装置２が備えるカレンダー登録機能を用いたユーザの登録内容（カレンダー登録内容）も加味して特定時間帯における消費電力量を予測してもよい。カレンダー登録機能とは、ユーザにより予め登録されたイベントと、そのイベントの開始時刻とに基づいて、対応する機器５の動作を制御することができる機能である。ここで、イベントには、例えば、“外出”、“帰宅”などが含まれる。特定時間帯に含まれる時間帯に何らかのイベントが登録されている場合、対応する機器５は、特定時間帯において、当該イベントの内容に応じた動作（停止も含む）を行う。このように、カレンダー登録内容も加味することで、特定時間帯における消費電力量の予測精度を高めることができる。 Note that the power consumption amount prediction unit 236 may predict the power consumption amount in a specific time period in consideration of user registration contents (calendar registration contents) using a calendar registration function provided in the control device 2. The calendar registration function is a function that can control the operation of the corresponding device 5 based on the event registered in advance by the user and the start time of the event. Here, the event includes, for example, “going out”, “returning home”, and the like. When any event is registered in a time zone included in the specific time zone, the corresponding device 5 performs an operation (including a stop) according to the content of the event in the specific time zone. Thus, the prediction accuracy of the power consumption amount in a specific time zone can be improved by taking into account the contents of calendar registration.
（実施形態３）
　続いて、本発明の実施形態３について説明する。なお、以下の説明において、実施形態１、２と共通する構成要素等については、同一の符号を付し、その説明を省略する。 (Embodiment 3)
Subsequently, Embodiment 3 of the present invention will be described. In the following description, components that are the same as those in the first and second embodiments are denoted by the same reference numerals and description thereof is omitted.
　図９は、本発明の実施形態３に係る機器制御システム１Ａの全体構成を示す図である。機器制御システム１Ａでは、実施形態１及び２の機器制御システム１と比較して、発電システム１２と、日射量センサ１３とが新たに追加されている。 FIG. 9 is a diagram showing an overall configuration of a device control system 1A according to Embodiment 3 of the present invention. In the device control system 1A, compared with the device control system 1 of the first and second embodiments, a power generation system 12 and a solar radiation sensor 13 are newly added.
　発電システム１２は、何れも図示しないが、太陽光発電パネル（ＰＶパネル）と、パワーコンディショナとを備える。発電システム１２は、ＰＶパネルが発電した電気をパワーコンディショナにより直流電力から交流電力に変換し、電力線Ｄ５を介して分電盤９に供給する。 Although not shown, the power generation system 12 includes a photovoltaic power generation panel (PV panel) and a power conditioner. The power generation system 12 converts the electricity generated by the PV panel from DC power to AC power using a power conditioner, and supplies it to the distribution board 9 via the power line D5.
　日射量センサ１３は、家屋Ｈ内の適切な場所、例えば、窓の近傍付近や屋根等に設置され、日射量を計測し、計測した結果を格納したデータ（日射量データ）を予め定めたタイミングで無線通信により制御装置２に送信する。なお、日射量センサ１３と制御装置２とが、通信線により接続される構成であってもよい。 The solar radiation amount sensor 13 is installed at an appropriate place in the house H, for example, in the vicinity of a window, near the roof, etc., measures the amount of solar radiation, and stores the measured results (sunlight amount data) at a predetermined timing. And transmitted to the control device 2 by wireless communication. The solar radiation amount sensor 13 and the control device 2 may be connected by a communication line.
　本実施形態の制御装置２が備える制御部２３は、機能的には、図１０に示すように、ユーザインタフェース処理部２３０と、ＤＲ受付部２３１と、モード切替部２３２と、特定時間帯設定部２３３と、充放電制御部２３４と、機器制御部２３５と、消費電力量予測部２３６と、必要電力量決定部２３７Ａと、日射量取得部２３８と、発電量予測部２３９と、を備える。 The control unit 23 included in the control device 2 of the present embodiment functionally includes a user interface processing unit 230, a DR reception unit 231, a mode switching unit 232, and a specific time zone setting unit as illustrated in FIG. 233, a charge / discharge control unit 234, a device control unit 235, a power consumption amount prediction unit 236, a required power amount determination unit 237A, a solar radiation amount acquisition unit 238, and a power generation amount prediction unit 239.
　日射量取得部２３８は、日射量センサ１３により計測された日射量を取得する。日射量取得部２３８は、予め定めたタイミングで、日射量センサ１３に対して、日射量を要求するためのデータ（日射量要求データ）を無線通信部２１を介して送信する。日射量センサ１３は、この日射量要求データを受信すると、計測した日射量を格納した応答データを制御装置２に無線送信する。日射量取得部２３８は、無線通信部２１を介して日射量センサ１３からの応答データを受信すると、この応答データから日射量を抽出する。日射量取得部２３８は、このようにして取得した日射量をＲＡＭ等に保存する。 The solar radiation amount acquisition unit 238 acquires the solar radiation amount measured by the solar radiation amount sensor 13. The solar radiation amount acquisition unit 238 transmits data (a solar radiation amount request data) for requesting the solar radiation amount to the solar radiation amount sensor 13 via the wireless communication unit 21 at a predetermined timing. When receiving the solar radiation amount request data, the solar radiation amount sensor 13 wirelessly transmits response data storing the measured solar radiation amount to the control device 2. When the solar radiation amount acquisition unit 238 receives response data from the solar radiation amount sensor 13 via the wireless communication unit 21, the solar radiation amount acquisition unit 238 extracts the solar radiation amount from the response data. The solar radiation amount acquisition unit 238 stores the solar radiation amount acquired in this manner in a RAM or the like.
　発電量予測部２３９は、日射量取得部２３８により取得された日射量に基づいて、特定時間帯における発電システム１２による発電量を予測する。必要電力量決定部２３７Ａは、消費電力量予測部２３６により予測された消費電力量と、発電量予測部２３９により予測された発電量とに基づいて必要電力量を決定する。 The power generation amount prediction unit 239 predicts the power generation amount by the power generation system 12 in a specific time zone based on the solar radiation amount acquired by the solar radiation amount acquisition unit 238. The required power amount determination unit 237A determines the required power amount based on the power consumption amount predicted by the power consumption amount prediction unit 236 and the power generation amount predicted by the power generation amount prediction unit 239.
　具体的には、予測された消費電力量が予測された発電量以上の場合、必要電力量決定部２３７Ａは、予測された消費電力量から予測された発電量を差し引くことで、買電のみの消費電力量を予測する。そして、必要電力量決定部２３７Ａは、予測した買電のみの消費電力量から必要電力量を決定する。例えば、予測した買電のみの消費電力量に予め定めた係数を乗じることで必要電力量を決定してもよいし、あるいは、基準電力量（例えば、２ｋＷｈ）に、予測した買電のみの消費電力量と予め定めた閾値との比較により得られた補正値（正又は負）を加算することで、必要電力量を決定してもよい。 Specifically, when the predicted power consumption is equal to or greater than the predicted power generation amount, the required power amount determination unit 237A subtracts the predicted power generation amount from the predicted power consumption amount to Predict power consumption. Then, the required power amount determining unit 237A determines the required power amount from the predicted power consumption amount of only the purchased power. For example, the required power amount may be determined by multiplying the predicted power consumption amount only for the purchased power by a predetermined coefficient, or the predicted power consumption amount is calculated based on the reference power amount (for example, 2 kWh). The required power amount may be determined by adding a correction value (positive or negative) obtained by comparing the power amount with a predetermined threshold value.
　また、予測された消費電力量が予測された発電量より少ない場合、必要電力量決定部２３７Ａは、予め定めた最少電力量を必要電力量として決定する。 If the predicted power consumption is smaller than the predicted power generation amount, the required power amount determination unit 237A determines a predetermined minimum power amount as the required power amount.
　以上説明したように、本実施形態の機器制御システム１Ａによれば、制御装置２は、特定時間帯の開始前に蓄電池７が蓄えておくべき必要電力量を、予測した特定時間帯における消費電力量と、予測した特定時間帯における発電量とに基づいて決定する。このため、蓄電池７の充放電をより効率的に行うことが可能となる。 As described above, according to the device control system 1A of the present embodiment, the control device 2 determines the power consumption that the storage battery 7 should store before the start of the specific time zone, and the power consumption in the predicted specific time zone. It is determined based on the amount and the power generation amount in the predicted specific time zone. For this reason, it becomes possible to charge / discharge the storage battery 7 more efficiently.
　なお、制御装置２は、日射量に関する情報を発電システム１２から取得してもよいし、あるいは、広域ネットワークＮを介した外部の装置との通信により取得してもよい。 Note that the control device 2 may acquire information on the amount of solar radiation from the power generation system 12 or may acquire it by communication with an external device via the wide area network N.
（実施形態４）
　続いて、本発明の実施形態４について説明する。なお、以下の説明において、実施形態１と共通する構成要素等については、同一の符号を付し、その説明を省略する。 (Embodiment 4)
Subsequently, Embodiment 4 of the present invention will be described. In the following description, components and the like that are common to the first embodiment are denoted by the same reference numerals, and description thereof is omitted.
　本実施形態の制御装置２が備える制御部２３には、図１１に示すように、実施形態１の制御部２３と比較し、事前制御決定部２４０が追加されている。事前制御決定部２４０は、特定時間帯より前の時間帯において特定の機器５に指定動作をさせるための事前制御内容を抑制レベル設定データ２２０に設定された抑制レベルに基づいて決定する。 As shown in FIG. 11, a pre-control determining unit 240 is added to the control unit 23 included in the control device 2 of the present embodiment as compared with the control unit 23 of the first embodiment. The prior control determination unit 240 determines the prior control content for causing the specific device 5 to perform the specified operation in the time zone before the specific time zone based on the suppression level set in the suppression level setting data 220.
　事前制御内容には、特定の機器５を識別する情報と、動作内容と、動作時間とが含まれる。特定の機器５として、例えば、エアコン、床暖房システム、給湯機等が該当する。 The pre-control content includes information for identifying a specific device 5, operation content, and operation time. Examples of the specific device 5 include an air conditioner, a floor heating system, and a water heater.
　機器制御部２３５は、ＤＲモードにおいて、事前制御決定部２４０により決定された事前制御内容に基づいて特定の機器５を制御（事前制御）する。例えば、特定時間帯においてエアコンの抑制制御が行われると、空気温度が上昇あるいは下降してユーザの快適性の低下を招くことになる。そこで、事前制御により、準備時間帯にエアコンを指定動作させて室内を予冷又は予暖しておく。これにより、エアコンの抑制制御によるユーザの快適性の低下を抑えることが可能となる。この場合、現時点（準備時間帯）において、エアコンが停止している場合には、通常の設定温度（目標温度）で運転を開始させ、一方、既に運転中の場合は、現在の空調強度を高くする制御を行う。具体的には、冷房運転時ならば設定温度を１～２℃下げ、暖房運転時ならば設定温度を１～２℃上げる制御を行う。あるいは風量を「強」に設定する等してもよい。 The device control unit 235 controls (pre-controls) a specific device 5 based on the pre-control content determined by the pre-control determination unit 240 in the DR mode. For example, if the suppression control of the air conditioner is performed in a specific time zone, the air temperature rises or falls, leading to a decrease in user comfort. Therefore, the pre-control causes the air conditioner to perform a specified operation during the preparation time period to precool or preheat the room. Accordingly, it is possible to suppress a decrease in user comfort due to the suppression control of the air conditioner. In this case, if the air conditioner is stopped at the current time (preparation time zone), the operation is started at the normal set temperature (target temperature). On the other hand, if the air conditioner is already operating, the current air conditioning strength is increased. Control. Specifically, control is performed to lower the set temperature by 1 to 2 ° C. during cooling operation and to raise the set temperature by 1 to 2 ° C. during heating operation. Alternatively, the air volume may be set to “strong”.
　床暖房システムについても、上記同様の事前制御を行うことで、室内を予冷又は予暖することができる。また、給湯機については、事前制御により準備時間帯に予め沸上げを完了しておくことで、特定時間帯の湯切れを防止することができる。 The floor heating system can also be pre-cooled or pre-heated by performing the same pre-control as described above. Moreover, about a hot water supply machine, it can prevent the hot water runout of a specific time slot | zone by completing boiling in advance in a preparation time slot | zone by prior control.
　以上説明したように、本実施形態の機器制御システム１によれば、制御装置２は、準備時間帯にエアコン等の特定の機器５に指定した動作をさせる事前制御を行うことで、室内を予冷又は予暖したり、予め沸上げを完了させておくことができる。このため、特定時間帯において、当該特定の機器５に対して消費電力を低下させるための制御（抑制制御）を行った場合でも、ユーザの快適性の低下を抑えることが可能となる。 As described above, according to the device control system 1 of the present embodiment, the control device 2 pre-cools the room by performing pre-control that causes the specific device 5 such as an air conditioner to perform an operation designated during the preparation time period. Alternatively, preheating can be performed or boiling can be completed in advance. For this reason, even when control (suppression control) for reducing power consumption is performed on the specific device 5 in a specific time zone, it is possible to suppress a decrease in user comfort.
　なお、実施形態２及び３の制御装置２が上記の事前制御に関する機能を備える構成であっても勿論構わない。 Of course, the control device 2 according to the second and third embodiments may be configured to have the above-described functions related to the prior control.

The mode may remain in the DR mode, and charging control or preliminary control in the preparation time zone, or suppression control in the specific time zone may be performed. At this time, the control device 2 may reset the time zone with the highest electricity bill unit price (or the time zone with the highest electricity bill) as the specific time zone.
