Description

本発明は、配電線路の電圧を管理する電力管理システム、および電力管理システムに用いる通知装置、制御装置、監視装置に関する。   The present invention relates to a power management system that manages the voltage of a distribution line, and a notification device, a control device, and a monitoring device that are used in the power management system.

近年、太陽光発電設備のように配電線路（電力系統）への電力の逆潮流が可能な分散型電源の普及が進んでいる。分散型電源が発電した電力は、需要家に設けられた電気負荷で消費されるほか、配電線路に逆潮流される。   In recent years, a distributed power source capable of reverse power flow to a distribution line (power system) such as a photovoltaic power generation facility has been spreading. The electric power generated by the distributed power source is consumed by the electric load provided at the consumer, and is reversely flowed to the distribution line.

太陽光、風力、水力、地熱などの自然エネルギーを電力に変換する分散型電源は、生成される電力を人為的に調節することが困難である。この種の発電設備は、電力変換装置（パワーコンディショナ）を備えており、電力変換装置による変換効率を低減させることにより出力を抑制することは可能である。   A distributed power source that converts natural energy such as sunlight, wind power, hydropower, and geothermal heat into electric power is difficult to artificially adjust the generated electric power. This type of power generation equipment includes a power conversion device (power conditioner), and it is possible to suppress the output by reducing the conversion efficiency of the power conversion device.

ところで、分散型電源の密度が高まると、配電線路に供給される電力量が配電線路から消費される電力量に対して過剰になり、結果的に、配電線路の電圧が上昇する可能性がある。たとえば、単相３線式２００／１００Ｖの低圧配電線路であれば、電気事業法によって、配電線路の電圧（電圧線と中性線の線間電圧）を１０１±６Ｖ（９５〜１０７Ｖ）の範囲に制御することが求められる。   By the way, when the density of the distributed power source increases, the amount of power supplied to the distribution line becomes excessive with respect to the amount of power consumed from the distribution line, and as a result, the voltage of the distribution line may increase. . For example, in the case of a single-phase three-wire 200 / 100V low-voltage distribution line, the voltage of the distribution line (voltage between the voltage line and the neutral line) is within a range of 101 ± 6V (95 to 107V) according to the Electricity Business Act. To be controlled.

配電線路の電圧が上限値である１０７Ｖを超える可能性がある場合、配電線路において対策を講じることが考えられるが、この種の対策は、電気事業者のみが大きな投資コストを負担することになるから、現状では採用が困難である。そのため、現状では、需要家において、配電線路への逆潮流を行う電力を低減させる対策が広く採用されている。   If there is a possibility that the voltage of the distribution line exceeds the upper limit of 107V, it is conceivable to take measures in the distribution line, but this kind of countermeasure only bears a large investment cost. Therefore, it is difficult to adopt at present. Therefore, at present, measures for reducing the electric power for reverse power flow to the distribution line are widely adopted by consumers.

しかしながら、この技術は、分散型電源が発電した電力の一部を無駄に捨てていることになるから、需要家にとっては分散型電源を導入したことによる費用対効果が損なわれることになる。また、分散型電源を導入することによる費用対効果が低いと、新たに分散型電源を導入しようとする意欲が損なわれる。   However, since this technology wastes a part of the power generated by the distributed power source, the cost effectiveness of the customer due to the introduction of the distributed power source is impaired. Also, if the cost effectiveness of introducing a distributed power source is low, the willingness to introduce a new distributed power source is impaired.

一方、大容量の蓄電池を搭載した電動車両の普及に鑑みて、電動車両に搭載された蓄電池を配電線路に電気的に接続し、蓄電池の充電および放電を制御することによって、配電線路の電圧を制限範囲に維持する技術が提案されている（たとえば、特許文献１参照）。特許文献１には、配電線路の電圧が第１の閾値を超えると、電動車両に搭載された蓄電池の充電を行い、配電線路の電圧が第２の閾値を下回ると、電動車両に搭載された蓄電池からの放電を行う技術が記載されている。   On the other hand, in view of the widespread use of electric vehicles equipped with large-capacity storage batteries, the storage battery mounted on the electric vehicle is electrically connected to the distribution line, and the charging and discharging of the storage battery is controlled, thereby controlling the voltage of the distribution line. A technique for maintaining the limit range has been proposed (see, for example, Patent Document 1). In Patent Document 1, when the voltage of the distribution line exceeds the first threshold, the storage battery mounted on the electric vehicle is charged, and when the voltage of the distribution line falls below the second threshold, the battery is mounted on the electric vehicle. A technique for discharging from a storage battery is described.

特開２０１２−５１３１号公報JP2012-5131A

しかしながら、引用文献１に記載された技術は、個々の需要家において電動車両の蓄電池への充電および放電を行っているから、電動車両の蓄電池に充電する期間に、電動車両が充電可能であるか否かは保証されない。そのため、配電線路の電圧が上昇している期間に、電動車両の蓄電池を利用することができない可能性がある。   However, since the technique described in the cited document 1 charges and discharges the storage battery of the electric vehicle in each consumer, can the electric vehicle be charged during the period of charging the storage battery of the electric vehicle? No, it is not guaranteed. Therefore, there is a possibility that the storage battery of the electric vehicle cannot be used during the period when the voltage of the distribution line is rising.

本発明は、配電線路の電圧が上昇しているときに、電動車両に搭載された蓄電池が充電されやすい状況を作り出すようにした電力管理システムを提供することを目的とする。   An object of this invention is to provide the electric power management system which produced the condition where the storage battery mounted in the electric vehicle is easy to be charged when the voltage of a distribution line is rising.

本発明に係る電力管理装置は、各所に設置され配電線路から受電し電動車両に搭載された走行用の蓄電池を充電する機能を有した電力調整装置と、前記配電線路の線間電圧が制限範囲の上限値以下に設定された基準値を超えたときに、当該配電線路から受電する前記電力調整装置が設置された場所を提示装置に通知する通知装置と、前記配電線路の線間電圧が前記制限範囲の上限値以下に維持されるように、前記蓄電池の充電が可能である前記電力調整装置の動作を制御する制御装置とを備えることを特徴とする。   The power management device according to the present invention includes a power adjusting device having a function of charging a running storage battery installed in an electric vehicle that is installed at various places and receives power from the distribution line, and the line voltage of the distribution line is within a limited range. When the reference value set below the upper limit value of is exceeded, a notification device that notifies the presentation device where the power adjustment device that receives power from the distribution line is installed, and the line voltage of the distribution line is the And a control device for controlling the operation of the power adjustment device capable of charging the storage battery so as to be maintained below the upper limit value of the limit range.

この電力管理装置において、前記配電線路は高圧配電線路であって、当該配電線路の電圧を監視する監視装置をさらに備え、前記監視装置は、前記配電線路から受電する前記電力調整装置が設置された場所を管理し、前記通知装置は、前記監視装置に付設されていることが好ましい。   In this power management apparatus, the distribution line is a high-voltage distribution line, and further includes a monitoring device that monitors the voltage of the distribution line, and the monitoring device is provided with the power adjustment device that receives power from the distribution line. The location is managed, and the notification device is preferably attached to the monitoring device.

この電力管理装置において、前記制御装置は、前記配電線路の電圧が前記基準値を超えることが予測される期間を計画期間として求める予測部と、前記計画期間に前記電力調整装置を利用するための予約を受け付ける受付部とを備えることが好ましい。   In this power management device, the control device uses a prediction unit that obtains a period during which the voltage of the distribution line is predicted to exceed the reference value as a planning period, and uses the power adjustment device during the planning period. It is preferable to include a reception unit that receives a reservation.

この電力管理装置において、前記電力調整装置は、前記蓄電池の充電および放電を行う機能を有し、前記配電線路から受電する電力の対価が第１の設定値よりも低い期間に前記蓄電池の充電を行い、前記配電線路から受電する電力の対価が第２の設定値よりも高い期間に前記蓄電池の放電を行うことが好ましい。   In this power management device, the power adjustment device has a function of charging and discharging the storage battery, and charges the storage battery during a period when the consideration of power received from the distribution line is lower than a first set value. Preferably, the storage battery is discharged during a period in which the value of power received from the distribution line is higher than the second set value.

本発明に係る通知装置、制御装置、監視装置は、それぞれ上述した電力管理システムに用いられる。   The notification device, the control device, and the monitoring device according to the present invention are each used in the above-described power management system.

本発明の構成によれば、配電線路の電圧が制限範囲の上限値を超える可能性がある場合に、蓄電池の充電が可能な電力調整装置の場所を提示装置に通知するから、電動車両に搭載された蓄電池が充電されやすい状況を作り出すことができる。その結果、電動車両に搭載された蓄電池を利用して、配電線路の電圧が引き下げられる可能性が高くなる。   According to the configuration of the present invention, when there is a possibility that the voltage of the distribution line may exceed the upper limit value of the limit range, the location of the power adjustment device capable of charging the storage battery is notified to the presentation device. It is possible to create a situation where the stored storage battery is easily charged. As a result, the possibility that the voltage of the distribution line is lowered using the storage battery mounted on the electric vehicle increases.

電力調整装置１０は、蓄電池６１の充電および放電を行う機能を有することが望ましい。この場合、電力調整装置１０は、配電線路５０から受電する電力の対価が第１の設定値よりも低い期間に蓄電池６１の充電を行い、配電線路５０から受電する電力の対価が第２の設定値よりも高い期間に蓄電池６１の放電を行うことが望ましい。   The power adjustment device 10 desirably has a function of charging and discharging the storage battery 61. In this case, the power adjustment device 10 charges the storage battery 61 in a period in which the consideration for the power received from the distribution line 50 is lower than the first set value, and the consideration for the power received from the distribution line 50 is the second setting. It is desirable to discharge the storage battery 61 during a period higher than the value.

以下、本実施形態を詳述する。以下の実施形態における配電線路５０は、６０００／３０００Ｖの高圧配電線路を想定し、配電線路５０の線間電圧を監視する監視装置７０を備える例を示す。ただし、配電線路５０が、２００／１００Ｖの低圧配電線路であることを妨げず、また、以下に説明する実施形態の技術思想は、監視装置７０を用いない構成であっても適用可能である。   Hereinafter, this embodiment will be described in detail. The distribution line 50 in the following embodiment is an example including a monitoring device 70 that monitors a line voltage of the distribution line 50 assuming a 6000 / 3000V high-voltage distribution line. However, the distribution line 50 is not prevented from being a 200 / 100V low-voltage distribution line, and the technical idea of the embodiment described below can be applied even if the monitoring device 70 is not used.

図２に示すように、配電線路５０から複数の需要家２が受電し、需要家２のうちの少なくとも一部の需要家２は、配電線路（電力系統）５０に電力を逆潮流させることが可能な分散型電源３を備える。分散型電源３は、ここでは太陽光発電設備を想定する。ただし、分散型電源３は、自然エネルギーを利用して発電する構成であれば、風力、水力、地熱などにより発電する構成であってもよい。また、需要家２は、戸建て住宅に限らず、集合住宅、商業施設、工場などであってもよい。分散型電源３は、配電線路５０に接続され、配電線路との系統連系が可能になっている。つまり、需要家２では、配電線路５０から受電した電力と、分散型電源３が発電した電力とが、電気負荷（図示せず）に供給可能であって、分散型電源３が発電した電力は、配電線路５０への逆潮流も可能になっている。   As shown in FIG. 2, a plurality of consumers 2 receive power from the distribution line 50, and at least some of the consumers 2 among the consumers 2 can cause power to flow backward in the distribution line (power system) 50. A possible distributed power supply 3 is provided. Here, the distributed power source 3 is assumed to be a solar power generation facility. However, as long as the distributed power source 3 is configured to generate power using natural energy, it may be configured to generate power using wind power, hydraulic power, geothermal heat, or the like. Further, the consumer 2 is not limited to a detached house, but may be an apartment house, a commercial facility, a factory, or the like. The distributed power source 3 is connected to the distribution line 50 and can be connected to the distribution line. That is, in the customer 2, the power received from the distribution line 50 and the power generated by the distributed power source 3 can be supplied to an electric load (not shown), and the power generated by the distributed power source 3 is The reverse power flow to the distribution line 50 is also possible.

分散型電源３が接続されている配電線路５０には、１ないし複数台の電力調整装置１０が接続される。電力調整装置１０は、電動車両６０に搭載された蓄電池６１の充電を行う機能を有している。さらに、電力調整装置１０は、蓄電池６１が放電する電力を配電線路５０に逆潮流させる機能を有していてもよい。ここでは、電力調整装置１０が、蓄電池６１の充電および放電を行う機能を有していると仮定して説明する。   One to a plurality of power conditioners 10 are connected to the distribution line 50 to which the distributed power source 3 is connected. The power adjustment device 10 has a function of charging the storage battery 61 mounted on the electric vehicle 60. Further, the power adjustment device 10 may have a function of causing the power discharged from the storage battery 61 to flow backward through the distribution line 50. Here, description will be made on the assumption that the power adjustment device 10 has a function of charging and discharging the storage battery 61.

電動車両６０は、ここでは走行用の電力を供給する蓄電池６１を搭載し、かつ直流電力を授受する電気自動車、電動二輪車などを想定している。したがって、電力調整装置１０は、配電線路５０の交流と蓄電池６１の直流との間で電力を双方向に変換する機能を有している。また、電力調整装置１０は、蓄電池６１の充電および放電の際の電流を調節する機能も備える。なお、電動車両６０が、プラグインハイブリッド車のように配電線路５０との間で交流電力を授受する構成である場合、電力調整装置１０は、充電と放電との切替のみを行うようにしてもよい。以下では、電動車両６０が電気自動車であって、電力調整装置１０による電力の変換を行う構成例について説明する。   Here, the electric vehicle 60 is assumed to be an electric vehicle, an electric two-wheeled vehicle, or the like that is equipped with a storage battery 61 that supplies electric power for traveling, and that receives DC power. Therefore, the power adjustment device 10 has a function of bidirectionally converting power between the AC of the distribution line 50 and the DC of the storage battery 61. The power adjustment device 10 also has a function of adjusting the current when the storage battery 61 is charged and discharged. When electric vehicle 60 is configured to exchange AC power with distribution line 50 as in a plug-in hybrid vehicle, power adjustment device 10 may perform only switching between charging and discharging. Good. Below, the electric vehicle 60 is an electric vehicle, and the structural example which performs the conversion of the electric power by the electric power adjustment apparatus 10 is demonstrated.

ところで、電力調整装置１０は、需要家２に設置されていてもよいが、時間貸しの駐車場、商業施設などの駐車場のように、不特定多数が利用できる駐車場４（図２参照）に設置されていることが望ましい。また、電動車両６０が、タクシー、バスなどである場合には、これらの電動車両６０が、専用に駐車する場所に電力調整装置１０が設けられていてもよい。あるいは、工場の駐車場、電動車両６０のレンタルを行う事業者の駐車場に電力調整装置１０が設けられていてもよい。   By the way, although the electric power adjustment apparatus 10 may be installed in the consumer 2, the parking lot 4 which an unspecified number can use like a parking lot of a time rental parking lot, a commercial facility, etc. (refer FIG. 2) It is desirable to be installed in. Moreover, when the electric vehicle 60 is a taxi, a bus, or the like, the power adjustment device 10 may be provided in a place where the electric vehicle 60 is parked exclusively. Or the electric power adjustment apparatus 10 may be provided in the parking lot of the factory which rents the electric vehicle 60, and the parking lot of a factory.

いずれの場所も、比較的多くの台数の電動車両６０を駐車させることが可能であり、電動車両６０が駐車している期間に、蓄電池６１の充電あるいは放電が可能になるという共通点を有している。図示例において、電力調整装置１０と蓄電池６１とは、ケーブルを用いて電力を授受する構成を想定しているが、電力調整装置１０と蓄電池６１との間で非接触で電力を授受する構成を採用することが望ましい。非接触で電力を授受すれば、電動車両６０の利用者が蓄電池６１への充電を行う意思がなく、ケーブルが接続されていない場合でも、必要に応じて蓄電池６１に充電することが可能になる。   In any place, a relatively large number of electric vehicles 60 can be parked, and the storage battery 61 can be charged or discharged while the electric vehicle 60 is parked. ing. In the illustrated example, the power adjustment device 10 and the storage battery 61 are assumed to have a configuration in which power is exchanged using a cable, but a configuration in which power is exchanged between the power adjustment device 10 and the storage battery 61 in a contactless manner. It is desirable to adopt. If power is exchanged in a contactless manner, the user of the electric vehicle 60 is not willing to charge the storage battery 61, and even when no cable is connected, the storage battery 61 can be charged as necessary. .

電力調整装置１０の動作は、制御装置４０に制御される。制御装置４０は、電力調整装置１０と通信する機能を有し、電力調整装置１０の動作状態の監視および制御を行う。電力調整装置１０は、制御装置４０と通信するために不図示の通信インターフェイス部（以下、通信インターフェイス部を「通信Ｉ／Ｆ部」という）と、蓄電池６１との電力の授受が可能な状態か否かを判断する判断部（図示せず）とを備える。さらに、電力調整装置１０は、蓄電池６１の蓄電量（残容量）および電動車両６０の識別情報を電動車両６０から取得する取得部（図示せず）を備えていることが望ましい。   The operation of the power adjustment device 10 is controlled by the control device 40. The control device 40 has a function of communicating with the power adjustment device 10 and monitors and controls the operation state of the power adjustment device 10. Whether the power adjustment device 10 is in a state in which power can be exchanged between the storage battery 61 and a communication interface unit (not shown) (hereinafter referred to as “communication I / F unit”) to communicate with the control device 40. A determination unit (not shown) for determining whether or not. Furthermore, it is desirable that the power adjustment device 10 includes an acquisition unit (not shown) that acquires the storage amount (remaining capacity) of the storage battery 61 and the identification information of the electric vehicle 60 from the electric vehicle 60.

制御装置４０は、電力調整装置１０と通信する通信Ｉ／Ｆ部（図示せず）を備える。さらに、制御装置４０は、監視装置７０（あるいは通知装置３０）との間でも通信Ｉ／Ｆ部を通して通信する。通信Ｉ／Ｆ部は、電波を伝送媒体とする無線通信、あるいはインターネットのような電気通信回線を用いる通信が可能であるように構成される。図示例では、電力調整装置１０と通知装置３０と制御装置４０が個別に設けられているが、通知装置３０と制御装置４０との一方あるいは両方が、電力調整装置１０の筐体に収納されていてもよい。   The control device 40 includes a communication I / F unit (not shown) that communicates with the power adjustment device 10. Further, the control device 40 communicates with the monitoring device 70 (or the notification device 30) through the communication I / F unit. The communication I / F unit is configured to be capable of wireless communication using radio waves as a transmission medium or communication using an electric communication line such as the Internet. In the illustrated example, the power adjustment device 10, the notification device 30, and the control device 40 are individually provided, but one or both of the notification device 30 and the control device 40 are accommodated in the casing of the power adjustment device 10. May be.

ところで、監視装置７０は、配電線路５０の電圧を監視する機能を有し、また、同じ配電線路５０に接続されている電力調整装置１０が設置されている場所を記憶している。監視装置７０は、配電線路５０の電圧が基準値を超えると、通知装置３０を通して電力調整装置１０の場所を提示装置１に通知し、さらに、提示装置１に対して蓄電池６１の充電を促す告知を行う。   By the way, the monitoring device 70 has a function of monitoring the voltage of the distribution line 50, and stores a place where the power adjustment device 10 connected to the same distribution line 50 is installed. When the voltage of the distribution line 50 exceeds the reference value, the monitoring device 70 notifies the presentation device 1 of the location of the power adjustment device 10 through the notification device 30 and further notifies the presentation device 1 to charge the storage battery 61. I do.

基準値は、配電線路５０の電圧について規定された制限範囲の上限値よりも低い値に設定される。たとえば、需要家２の内部配線である電力線において、電圧線と中性線との間の線間電圧は、９５〜１０７Ｖが制限範囲になるから、基準値は、たとえば１０５Ｖなどに設定される。   The reference value is set to a value lower than the upper limit value of the limit range defined for the voltage of the distribution line 50. For example, in the power line that is the internal wiring of the customer 2, the line voltage between the voltage line and the neutral line is in a limited range of 95 to 107V, so the reference value is set to 105V, for example.

通知装置３０が提示装置１に通知を行う際に、提示装置１を利用する利用者に、提示された電力調整装置１０を用いて電動車両６０に充電を行うと特典が得られることを告知すれば、利用者に対して充電を動機付けることができる。この種の特典としては、配電線路５０の電圧上昇を回避するという補助（アンシラリー）を行うことに対して、通常よりも電気料金を引き下げること、あるいは電力調整装置１０が設置されている施設で利用可能なクーポンの発行などが考えられる。   When the notification device 30 notifies the presentation device 1, the user who uses the presentation device 1 is notified that the benefit can be obtained by charging the electric vehicle 60 using the presented power adjustment device 10. If so, charging can be motivated for the user. As a privilege of this kind, for subsidies (ancillary) to avoid the voltage increase of the distribution line 50, it is possible to lower the electricity bill than usual, or use it at the facility where the power adjustment device 10 is installed. Possible issuance of possible coupons.

提示装置１は、たとえば、移動体電話機、タブレット端末、カーナビゲーション装置のように、移動体通信が可能であって、かつ提示された内容を表示する機能を有する汎用装置を用いることが望ましい。後述するように、監視装置７０が電圧を監視している配電線路５０に接続された電力調整装置１０を用いて蓄電池６１の充電を行う必要がある。そのため、電力調整装置１０から所定の距離範囲（たとえば、半径５ｋｍ以内など）に存在する提示装置１のみに通知装置３０から上述した通知を行うようにするのが望ましい。このような動作は、提示装置１がＧＰＳ（Global Positioning System）のような測位システムを備えている場合、ＧＰＳとの連動によって実現される。   The presentation device 1 is desirably a general-purpose device capable of mobile communication and having a function of displaying the presented content, such as a mobile phone, a tablet terminal, and a car navigation device. As will be described later, it is necessary to charge the storage battery 61 using the power adjustment device 10 connected to the distribution line 50 whose voltage is monitored by the monitoring device 70. Therefore, it is desirable that the notification described above from the notification device 30 is performed only to the presentation device 1 existing within a predetermined distance range (for example, within a radius of 5 km) from the power adjustment device 10. Such operation | movement is implement | achieved by interlock | cooperating with GPS, when the presentation apparatus 1 is provided with the positioning system like GPS (Global Positioning System).

上述した構成例では、配電線路５０の電圧を監視する監視装置７０を設け、かつ監視装置７０が電力調整装置１０の場所を管理しており、監視装置７０に通知装置３０が設けられている。したがって、監視装置７０が複数の電力調整装置１０を集約して管理することになり、監視装置７０は、いわゆるアグリゲータとして機能する。   In the configuration example described above, the monitoring device 70 that monitors the voltage of the distribution line 50 is provided, the monitoring device 70 manages the location of the power adjustment device 10, and the notification device 30 is provided in the monitoring device 70. Therefore, the monitoring device 70 collects and manages the plurality of power adjustment devices 10, and the monitoring device 70 functions as a so-called aggregator.

これに対して、通知装置３０が電力調整装置１０に設けてもよい。この場合には、個々の電力調整装置１０が、配電線路５０の電圧を監視し、電力調整装置１０が場所も管理することになる。   On the other hand, the notification device 30 may be provided in the power adjustment device 10. In this case, each power conditioner 10 monitors the voltage of the distribution line 50, and the power conditioner 10 also manages the location.

上述した動作例は、配電線路５０の電圧が上昇し、制限範囲の上限値を超える可能性がある場合に、電力調整装置１０から蓄電池６１への充電を促す通知を行うようにしているが、提示装置１への提示から充電が開始されるまでに時間遅れが生じる。このような時間遅れに対応するために、配電線路５０から受電して蓄電池を充電する蓄電設備を付加してもよい。このような蓄電装置を設けておけば、電動車両６０の台数が必要台数に達しない場合でも、蓄電設備を補助に用いることによって、配電線路５０の電圧を制限範囲に維持することが可能になる。   In the above-described operation example, when the voltage of the distribution line 50 is increased and may exceed the upper limit value of the limit range, the notification that prompts the storage battery 61 to be charged from the power adjustment device 10 is performed. There is a time delay from the presentation to the presentation device 1 to the start of charging. In order to cope with such a time delay, a power storage facility that receives power from the distribution line 50 and charges the storage battery may be added. If such a power storage device is provided, even when the number of electric vehicles 60 does not reach the required number, it is possible to maintain the voltage of the distribution line 50 within the limit range by using the power storage equipment as an auxiliary. .

以下に説明する構成例は、配電線路５０の電圧が制限範囲の上限値を超える可能性のある期間を予測し、当該期間に電動車両６０を充電可能な状態に待機させることを目的としている。   The configuration example described below is intended to predict a period in which the voltage of the distribution line 50 may exceed the upper limit value of the limit range, and to wait for the electric vehicle 60 to be charged during the period.

すなわち、制御装置４０は、配電線路５０の電圧が基準値を超えることが予測される期間を求める予測部４１を備える。予測部４１は、分散型電源３が発電する電力、需要家２ごとに消費する電力、電力調整装置１０から電動車両６０に供給される電力などの情報を用いて、配電線路５０に流入する電力と配電線路５０から流出する電力とを予測する。予測に際しては、過去の実績の情報、天気予報（天候、気温、風速など）の情報などが用いられる。   That is, the control device 40 includes a prediction unit 41 that obtains a period during which the voltage of the distribution line 50 is predicted to exceed the reference value. The prediction unit 41 uses information such as the power generated by the distributed power source 3, the power consumed for each customer 2, the power supplied from the power adjustment device 10 to the electric vehicle 60, and the power flowing into the distribution line 50. And the electric power flowing out from the distribution line 50 are predicted. For the prediction, information on past results, information on weather forecasts (weather, temperature, wind speed, etc.) are used.

予測部４１による予測は、当日の午後、あるいは翌日に関する予測であって、予測によって配電線路５０の電圧が基準値を超える可能性が予測される期間を計画期間に定め、この計画期間において蓄電池６１に充電することを希望する利用者を募集する。つまり、制御装置４０に設けられた受付部４２は、予測部４１が定めた計画期間を提示装置１に通知し、計画期間に電力調整装置１０を利用するための予約を受け付ける。   The prediction by the prediction unit 41 is a prediction regarding the afternoon of the day or the next day, and a period during which the possibility that the voltage of the distribution line 50 exceeds the reference value is predicted by the prediction is set as the planning period. Recruit users who want to charge. That is, the reception unit 42 provided in the control device 40 notifies the presentation device 1 of the plan period determined by the prediction unit 41 and receives a reservation for using the power adjustment device 10 during the plan period.

このように、計画期間において充電を行う電動車両６０を募集するから、配電線路５０の電圧を制限範囲に維持するために必要な台数の電動車両６０を確保しやすくなる。したがって、電動車両６０の充電のみによって、配電線路５０の電圧を制限範囲に維持することが容易になる。   In this way, since the electric vehicles 60 that are charged during the planning period are recruited, it becomes easy to secure the number of electric vehicles 60 necessary for maintaining the voltage of the distribution line 50 in the restricted range. Therefore, it becomes easy to maintain the voltage of the distribution line 50 in the limit range only by charging the electric vehicle 60.

上述した制御装置４０は、プログラムに従って動作するプロセッサを備えたコンピュータを主なハードウェア要素として備える。この種のコンピュータは、メモリをプロセッサと一体に備えるマイコン、プロセッサとメモリとを個別に備える構成などがある。コンピュータを、上述した制御装置４０として機能させるためのプログラムは、コンピュータに搭載されるＲＯＭ（Read Only Memory）により提供されるか、電気通信回線を通して提供されるか、コンピュータで読取可能な記録媒体により提供される。   The control device 40 described above includes a computer including a processor that operates according to a program as a main hardware element. This type of computer includes a microcomputer that includes a memory integrally with a processor, and a configuration that includes a processor and a memory separately. A program for causing a computer to function as the control device 40 described above is provided by a ROM (Read Only Memory) mounted on the computer, provided through an electric communication line, or by a computer-readable recording medium. Provided.

また、上述した構成例は、電力調整装置１０が蓄電池６１を充電する電力を供給する場合について説明したが、電力調整装置１０は蓄電池６１の電力を配電線路５０に供給する機能を有していてもよい。つまり、電力調整装置１０は、蓄電池６１の電力を双方向に授受する構成であってもよい。この場合、電力調整装置１０は、配電線路５０から受電する電力の対価が第１の設定値よりも低い期間に蓄電池６１の充電を行い、配電線路５０から受電する電力の対価が第２の設定値よりも高い期間に蓄電池６１の放電を行うことが望ましい。   Moreover, although the structural example mentioned above demonstrated the case where the power adjustment apparatus 10 supplies the electric power which charges the storage battery 61, the power adjustment apparatus 10 has a function which supplies the electric power of the storage battery 61 to the distribution line 50. Also good. In other words, the power adjustment device 10 may be configured to exchange the power of the storage battery 61 in both directions. In this case, the power adjustment device 10 charges the storage battery 61 in a period in which the consideration for the power received from the distribution line 50 is lower than the first set value, and the consideration for the power received from the distribution line 50 is the second setting. It is desirable to discharge the storage battery 61 during a period higher than the value.
