Description

電力需要施設における電力貯蔵装置及びシステムに係り、特に施設外へ移動して利用することが可能な電力貯蔵装置及びこの電力貯蔵装置を含んだ電力貯蔵システムに関する。   The present invention relates to a power storage device and system in a power demand facility, and more particularly to a power storage device that can be used by moving outside the facility and a power storage system including the power storage device.

住宅等の電力需要施設において、停電時のバックアップ、電力負荷平準化、電力ピークカットや、太陽光・風力等の自然エネルギー発電電力の貯蔵等を目的として、蓄電池等を用いた蓄電システムが開発されている（例えば、特許文献１）。   In power demand facilities such as houses, power storage systems using storage batteries have been developed for the purpose of backup during power outages, power load leveling, power peak cut, and storage of natural energy generated power such as solar and wind power. (For example, Patent Document 1).

しかし、これらの蓄電システムは、電力線や通信線、或いは制御線を住宅等の配電盤及び各種計量器との間に予め配線された据置型設備であるので、住宅等の据付け場所以外に移動させることができない。すなわち、用途が据付け場所でのものに限定されてしまい、総合的に勘案した場合の蓄電池のコストが高くつくことから、こうしたシステムの普及の妨げとなっている。
特開２００５−１３０６０６号公報 However, since these power storage systems are stationary equipment in which power lines, communication lines, or control lines are wired in advance between a distribution board such as a house and various measuring instruments, they can be moved to places other than the installation place such as a house. I can't. That is, the usage is limited to the installation place, and the cost of the storage battery is high when comprehensively taken into consideration, which hinders the spread of such a system.

次に、電力消費施設２について説明する。
配電盤４０は、電力消費施設２の電力の分配を制御する装置であって、開閉機器類（不図示）、自家発電電力検出手段４２、電気機器電力検出手段４３、配電盤制御手段４６等を有する。 Next, the power consumption facility 2 will be described.
The switchboard 40 is a device that controls the distribution of power in the power consuming facility 2, and includes switchgear (not shown), private power generation detection means 42, electrical equipment power detection means 43, switchboard control means 46, and the like.

自家発電装置５２は、太陽光発電や太陽熱発電、風力発電等の電力消費施設２に備えられている発電装置である。自家発電電力検出手段４２は、自家発電装置５２で発電された電力量ＰＧを検出する手段である。
電気機器５３は、テレビ、冷蔵庫、照明器具、電気給湯器、空調機器、ＩＨクッキングヒータ等の電力消費機器である。電気機器電力検出手段４３は、電気機器５３で消費されている電力量ＰＬを検出する手段である。 The private power generation device 52 is a power generation device provided in the power consuming facility 2 such as solar power generation, solar thermal power generation, and wind power generation.

Electrical equipment power detecting means 43 is a means for detecting an amount of power P L that is consumed by the electric device 53.

商用電源５１は、電気事業者等によって外部から供給される電源である。商用電源５１から供給された電力を随時使用（買電）できるのみならず、余剰電力を商用電源５１へ随時供給（売電）することができる。   The commercial power source 51 is a power source supplied from the outside by an electric power company or the like. Not only can the power supplied from the commercial power supply 51 be used (power purchase) at any time, but also surplus power can be supplied (power sold) to the commercial power supply 51 at any time.

配電盤通信手段４５は、自家発電電力検出手段４２で検出した電力発電量ＰＧ、電気機器電力検出手段４３で検出した電力消費量ＰＬを電力貯蔵装置１へ送信するとともに、電力貯蔵装置１から蓄電池制御手段３０により制御されている蓄電池１０の充電の電力量ＰＢ又は放電の電力量（−ＰＢ）を受信する。 Switchboard communication means 45 transmits power generation amount detected by the self-generated power detecting means 42 P G, the power consumption P L detected by the electrical equipment power detection unit 43 to the power storage device 1, the power storage device 1 The power amount P B for charging or the power amount (−P B ) for discharging the storage battery 10 controlled by the storage battery control means 30 is received.

以下、蓄電池制御手段３０及び配電盤制御手段４６における制御の内容について説明する。
図２は、電力需要者の電力料金をなるべく安くするために、蓄電池制御手段３０及び配電盤制御手段４６が実行する処理を示したフロー図である。なお、ここでの電力需要者は、多くの電気事業者が導入している深夜時間帯等における割引電気料金制度に基づく契約を行っていることを前提とする。また、電力需要者は、自然エネルギー等（太陽光、太陽熱、風力等）による自家発電を行い、自家消費分を上回る電力を発電した場合等、余剰電力が発生したときは、その余剰電力（−Ｐｓ）を電力事業者に販売する売電を行う。 Hereinafter, the contents of control in the storage battery control means 30 and the switchboard control means 46 will be described.
FIG. 2 is a flowchart showing the processing executed by the storage battery control means 30 and the switchboard control means 46 in order to reduce the power charge of the power consumer as much as possible. Here, it is assumed that the power consumer has a contract based on a discounted electricity rate system in the late-night time period that is introduced by many electric utilities. In addition, when a surplus power is generated, such as when the power consumer generates self-generated electricity using natural energy (sunlight, solar heat, wind power, etc.) and generates more power than the self-consumed portion, the surplus power (− carry out the sale of electricity to sell the P s) to the power company.

まず、蓄電池制御手段３０は、時計機能部３２が指し示す日付及び時刻に基づいて現時点が電気料金割引時間帯であるか否かを判定する（Ｓ２０２）。現時点が電気料金割引時間帯であれば（Ｓ２０２：ＹＥＳ）、蓄電池制御手段３０は、蓄電池１０の充電状態を判定する（Ｓ２０４）。その結果、蓄電池１０が完全充電状態でなければ（Ｓ２０４：ＮＯ）、蓄電池制御手段３０は蓄電池１０に充電量ＰＢで充電させるが、配電盤制御手段４６は電気機器５３の電力消費量ＰＬ及び蓄電池１０の充電量ＰＢの和が自家発電装置５２の発電量ＰＧを上回っているかどうかを判定する（Ｓ２０６）。電気機器５３の電力消費量ＰＬ及び蓄電池１０の充電量ＰＢの和が自家発電装置５２の発電量ＰＧを上回る場合（Ｓ２０６：ＹＥＳ）、蓄電池制御手段３０は蓄電池１０が完全充電状態になるまで充電させ、配電盤制御手段４６は不足する電力量Ｐｓ＝（電力消費量ＰＬ＋充電量ＰＢ−発電量ＰＧ）を商用電源５１から買電する（Ｓ２０８）。一方、電気機器５３の電力消費量ＰＬ及び蓄電池１０の充電量ＰＢの和が自家発電装置５２の発電量ＰＧを下回る場合（Ｓ２０６：ＮＯ）、蓄電池制御手段３０は蓄電池１０が完全充電状態になるまで充電させ、配電盤制御手段４６は余剰電力量（−Ｐｓ）＝（発電量ＰＧ−電力消費量ＰＬ−充電量ＰＢ）を商用電源５１へ売電する（Ｓ２１０）。 First, the storage battery control means 30 determines whether or not the current time is an electricity rate discount time zone based on the date and time indicated by the clock function unit 32 (S202). If the current time is the electricity rate discount time zone (S202: YES), the storage battery control means 30 determines the state of charge of the storage battery 10 (S204). As a result, if the battery 10 is fully charged state (S204: NO), the storage battery control unit 30 is to be charged at the charging amount P B to the battery 10, the switchboard control means 46 power consumption of electrical equipment 53 P L and determining whether the sum of the charge amount P B of the battery 10 is above the power generation amount P G of private power generation apparatus 52 (S206).

現在が電気料金割引時間帯でなければ（Ｓ２０２：ＮＯ）、蓄電池制御手段３０は、入力受付手段３４により入力された電気自動車の利用予定時刻までの時間を判定する（Ｓ２１８）。もし、電気自動車の利用予定時刻までの時間が所定の時間（蓄電池１０を完全充電状態にするのに必要な時間であって、例えば４時間）未満であれば（Ｓ２１８：ＹＥＳ）、蓄電池制御手段３０は、蓄電池１０の充電状態を判定する（Ｓ２２０）。そして、蓄電池１０が完全充電状態でなければ（Ｓ２２０：ＮＯ）、蓄電池制御手段３０は蓄電池１０に充電量ＰＢで充電させるが、配電盤制御手段４６は電気機器５３の電力消費量ＰＬ及び蓄電池１０の充電量ＰＢの和が自家発電装置５２の発電量ＰＧを上回っているかどうかを判定する（Ｓ２２２）。電気機器５３の電力消費量ＰＬ及び蓄電池１０の充電量ＰＢの和が自家発電装置５２の発電量ＰＧを上回る場合（Ｓ２２２：ＹＥＳ）、蓄電池制御手段３０は蓄電池１０が完全充電状態になるまで充電させ、配電盤制御手段４６は不足する電力量Ｐｓ＝（電力消費量ＰＬ＋充電量ＰＢ−発電量ＰＧ）を商用電源５１から買電する（Ｓ２２４）。一方、電気機器５３の電力消費量ＰＬ及び蓄電池１０の充電量ＰＢの和が自家発電装置５２の発電量ＰＧを下回る場合（Ｓ２２２：ＮＯ）、蓄電池制御手段３０は蓄電池１０が完全充電状態になるまで充電させ、配電盤制御手段４６は余剰電力量（−Ｐｓ）＝（発電量ＰＧ−電力消費量ＰＬ−充電量ＰＢ）を商用電源５１へ売電する（Ｓ２２６）。 If the current time is not the electricity rate discount time zone (S202: NO), the storage battery control means 30 determines the time until the scheduled use time of the electric vehicle input by the input reception means 34 (S218). If the time until the scheduled use time of the electric vehicle is less than a predetermined time (the time required to make the storage battery 10 fully charged, for example, 4 hours) (S218: YES), the storage battery control means 30 determines the charge state of the storage battery 10 (S220). Then, if the fully charged battery 10 (S220: NO), the storage battery control unit 30 is to be charged at the charging amount P B to the battery 10, the switchboard control means 46 power consumption of electrical equipment 53 P L and accumulators the sum of the charge amount P B of 10 determines whether is greater than the power generation amount P G of private power generation apparatus 52 (S222). If the sum of the charge amount P B of the power consumption P L and the battery 10 of the electric device 53 exceeds the power generation amount P G of private power generation apparatus 52 (S222: YES), the storage battery control unit 30 the battery 10 is fully charged state The switchboard control means 46 purchases the insufficient power amount P s = (power consumption amount P L + charge amount P B −power generation amount P G ) from the commercial power source 51 (S224).

Ｓ２２０の時点で蓄電池１０が完全充電状態である場合（Ｓ２２０：ＹＥＳ）又はＳ２２４若しくはＳ２２６において蓄電池１０が完全充電状態となった場合は、配電盤制御手段４６は電気機器５３の電力消費量ＰＬが自家発電装置５２の発電量ＰＧを上回るかどうかを判定する（Ｓ２２８）。電気機器５３の電力消費量ＰＬが自家発電装置５２の発電量ＰＧを上回る場合（Ｓ２２８：ＹＥＳ）、蓄電池制御手段３０は蓄電池１０を充電も放電もさせずに待機させ、配電盤制御手段４６は不足する電力量Ｐｓ＝（電力消費量ＰＬ−発電量ＰＧ）を商用電源５１から買電する（Ｓ２３０）。一方、電気機器５３の電力消費量ＰＬが自家発電装置５２の発電量ＰＧを下回る場合（Ｓ２２８：ＮＯ）、蓄電池制御手段３０は蓄電池１０を充電も放電もさせずに待機させつつ、配電盤制御手段４６は余剰電力量（−Ｐｓ）＝（発電量ＰＧ−電力消費量ＰＬ）を商用電源５１へ売電する（Ｓ２３２）。 If the battery 10 is fully charged at the time of S220 (S220: YES) if the battery 10 becomes fully charged state or in S224 or S226, the switchboard control unit 46 electric power consumption P L of the electrical device 53 determining whether exceeds the power generation amount P G of private power generation apparatus 52 (S228). If the power consumption P L of the electrical device 53 exceeds the power generation amount P G of private power generation apparatus 52 (S228: YES), the storage battery control unit 30 is on standby without charge was also discharged also the accumulator 10, the switchboard control unit 46 Purchases the power amount P s = (power consumption amount P L −power generation amount P G ) from the commercial power source 51 (S230). On the other hand, if the power consumption P L of the electrical device 53 is below a power generation amount P G of private power generation apparatus 52 (S228: NO), the storage battery control means 30 while waiting without charge was also discharged also the accumulator 10, the switchboard The control means 46 sells the surplus power amount (−P s ) = (power generation amount P G −power consumption amount P L ) to the commercial power source 51 (S232).

電気自動車の利用予定時刻までの時間が所定の時間未満でなければ（Ｓ２１８：ＮＯ）、蓄電池制御手段３０は自家発電装置５２の発電量ＰＧが電気機器５３の電力消費量ＰＬを上回るかどうかを判定する（Ｓ２３４）。自家発電装置５２の発電量ＰＧが電気機器５３の電力消費量ＰＬを上回っている場合（Ｓ２３４：ＹＥＳ）、さらに蓄電池制御手段３０は蓄電池１０の充電状態を判定する（Ｓ２３６）。そして、蓄電池１０が完全充電状態であれば（Ｓ２３６：ＹＥＳ）、蓄電池制御手段３０は蓄電池１０には充電も放電もさせず、また配電盤制御手段４６は余剰電力量（−Ｐｓ）＝（発電量ＰＧ−電力消費量ＰＬ）を商用電源５１へ売電する（Ｓ２３８）。一方、もし蓄電池１０が完全充電状態でなければ（Ｓ２３６：ＮＯ）、蓄電池制御手段３０は蓄電池１０に完全充電状態になるまで充電させつつ、配電盤制御手段４６は余剰電力量（−Ｐｓ）＝（発電量ＰＧ−電力消費量ＰＬ−充電量ＰＢ）を商用電源５１へ売電する（Ｓ２４０）。 If time to use scheduled time of the electric vehicle is not less than the predetermined time (S218: NO), whether the storage battery control means 30 power generation amount P G of private power generation device 52 exceeds the power consumption P L of the electrical device 53 It is determined whether or not (S234). If power generation amount P G of private power generation system 52 exceeds the power consumption P L of the electrical device 53 (S234: YES), further battery control unit 30 determines the state of charge of the battery 10 (S236). If the storage battery 10 is in a fully charged state (S236: YES), the storage battery control means 30 does not charge or discharge the storage battery 10, and the switchboard control means 46 determines the surplus power (−P s ) = (power generation). The amount P G -the power consumption amount P L ) is sold to the commercial power source 51 (S238). On the other hand, if the storage battery 10 is not in a fully charged state (S236: NO), the storage battery control means 30 charges the storage battery 10 until it is in a fully charged state, while the switchboard control means 46 has a surplus power (−P s ) = (Power generation amount P G -Power consumption amount P L -Charge amount P B ) is sold to the commercial power source 51 (S240).

一方、自家発電装置５２の発電量ＰＧが電気機器５３の電力消費量ＰＬを下回っている場合は（Ｓ２３４：ＮＯ）、蓄電池制御手段３０は蓄電池１０に不足する電力量Ｐｓ＝（電力消費量ＰＬ−発電量ＰＧ）を放電させる（Ｓ２４２）。 On the other hand, when the power generation amount P G of private power generation apparatus 52 is below the power consumption P L of the electrical device 53 (S234: NO), the amount of power storage battery control unit 30 is insufficient in battery 10 P s = (power The consumption amount P L -the power generation amount P G ) is discharged (S242).

以上の処理フローを繰り返すことにより、蓄電池制御手段３０及び配電盤制御手段４６は、各時点において蓄電池１０の充放電や商用電源５１との売買電など必要な制御を行う。   By repeating the above processing flow, the storage battery control means 30 and the switchboard control means 46 perform necessary controls such as charging / discharging of the storage battery 10 and buying and selling of electricity with the commercial power source 51 at each time point.

As a premise, it is premised that the storage battery control means 30 is input with information related to a power demand peak such as a peak time of power demand. In addition, when a consumer of power generates surplus power, such as when generating self-generated electricity using natural energy (solar, solar heat, wind power, etc.) and generating power that exceeds the amount consumed by himself / herself, the surplus power is Sell power to be sold to businesses.

まず、蓄電池制御手段３０は、時計機能部３２が指し示す日付及び時刻に基づいて、現時点が電力需要のピーク時間帯であるか否かを判定する（Ｓ３０２）。現時点が電力需要のピーク時間帯でなければ（Ｓ３０２：ＮＯ）、蓄電池１０の充電状態を判定する（Ｓ３０４）。また、現在が電力需要のピーク時間帯であれば（Ｓ３０２：ＹＥＳ）、電気自動車の利用予定時刻までの時間を判定する（Ｓ３１８）。以降、図２で示した処理フローと同じ処理を行う。   First, the storage battery control means 30 determines whether or not the current time is a peak time zone of power demand based on the date and time indicated by the clock function unit 32 (S302). If the current time is not the peak time of power demand (S302: NO), the state of charge of the storage battery 10 is determined (S304). If the current time is the peak time of power demand (S302: YES), the time until the scheduled use time of the electric vehicle is determined (S318). Thereafter, the same processing as the processing flow shown in FIG. 2 is performed.
