Description

本発明は、電力貯蔵システム、ルート発生装置及びルート発生方法に関し、特に商用電力供給源からの電力を蓄電する電力貯蔵システム、並びにこのシステムに利用されるルート発生装置及びルート発生方法に関する。   The present invention relates to a power storage system, a route generation device, and a route generation method, and more particularly to a power storage system that stores power from a commercial power supply source, and a route generation device and a route generation method used in this system.

商用電力供給源からの電力を蓄電する電力貯蔵システムとして、本願の出願人による特許文献１に記載のものがある。ここに開示された電力貯蔵システムは、蓄電池への充電時はコンバータとして、放電時はインバータとして機能する双方向電力変換器と、商用電力供給源と双方向電力変換器と負荷との間に設けられて電力の選択を行う電力選択手段と、電力選択手段が行う電力選択を制御する制御手段を備える。そして、このシステムでは、夜間運転モード、放電運転モード、系統補充運転モードが実行される。夜間運転モードは、夜間料金適用時間帯は商用電力供給源から蓄電池に充電を行うとともに負荷に電力を供給するモードである。放電運転モードはデイタイムに負荷の消費電力に応じて蓄電池からのみの負荷への電力供給を行うモードである。系統補充運転モードは商用電力供給源と蓄電池からの負荷への電力供給を並列して行うモードである。このようなシステム、特に系統補充運転モードにより、負荷からの出力容量以上の電力要求があった場合でも、夜間電力の有効利用と、デイタイム電力の使用を抑制可能としている。   There exists a thing of patent document 1 by the applicant of this application as an electric power storage system which stores the electric power from a commercial power supply source. The power storage system disclosed herein is provided between a bidirectional power converter that functions as a converter when charging a storage battery and as an inverter when discharged, and between a commercial power supply source, the bidirectional power converter, and a load. Power selection means for selecting power and control means for controlling power selection performed by the power selection means. In this system, the night operation mode, the discharge operation mode, and the system supplement operation mode are executed. The night operation mode is a mode in which the storage battery is charged from the commercial power supply source and power is supplied to the load during the night charge application time zone. The discharge operation mode is a mode in which power is supplied only to the load from the storage battery according to the power consumption of the load on a daytime basis. The system replenishment operation mode is a mode in which power supply from a commercial power supply source and a storage battery to a load is performed in parallel. With such a system, particularly the system replenishment operation mode, it is possible to suppress the effective use of nighttime power and the use of daytime power even when there is a power demand exceeding the output capacity from the load.

特開２００４−２２２４５６号公報JP 2004-222456 A

また、本願の出願人は、特願２００４−３３３６８６号において、上記システムの改良技術を提案している。この改良点は、以下のとおりである。放電運転モードが、夜間料金適用時間帯以外の時間帯においては、負荷の消費電力が所定の値未満のときは蓄電手段からのみの負荷への電力供給を行うとともに、太陽光発電手段からの余剰電力を商用電力側に逆潮流させるモードになっている。また、系統補充運転モードが、負荷の消費電力が前記所定の値以上のときは、前記所定の値までの消費電力については蓄電手段から電力供給を行い、前記所定の値以上の消費電力については商用電力及び太陽光発電手段から電力供給するモードになっている。   Moreover, the applicant of this application has proposed the improvement technique of the said system in Japanese Patent Application No. 2004-333686. The improvements are as follows. When the discharge operation mode is in a time zone other than the nighttime charge application time zone, when the power consumption of the load is less than a predetermined value, power is supplied only to the load from the power storage means and surplus from the solar power generation means It is in a mode to reverse power flow to the commercial power side. In addition, when the power consumption of the load is greater than or equal to the predetermined value in the system supplement operation mode, power is supplied from the storage means for power consumption up to the predetermined value, and for power consumption greater than or equal to the predetermined value. It is in a mode for supplying power from commercial power and solar power generation means.

このような改良の理由の一つとして国内の売買契約の中では蓄電した夜間・深夜電力を商用電力側に逆潮流することが許可されていないことがあるが、特願２００４−３３３６８６号においては、太陽光発電手段と商用電力供給源との関係、太陽光発電手段と蓄電手段との関係、商用電力供給源と蓄電手段との関係は、基本構成として独立した関係としており、商用電力供給源との関係のための第１の太陽光発電手段と蓄電手段との関係の第２の太陽光発電手段との複数の太陽光発電手段を準備していた。   One of the reasons for such improvement is that in domestic sales contracts, it is not allowed to reverse the stored night / midnight power to the commercial power side, but in Japanese Patent Application No. 2004-333686 The relationship between the solar power generation means and the commercial power supply source, the relationship between the solar power generation means and the power storage means, and the relationship between the commercial power supply source and the power storage means are independent as basic configurations. A plurality of solar power generation means including a first solar power generation means for the relationship with the second solar power generation means for the relationship with the power storage means has been prepared.

しかしながら、上記のように負荷での消費電力への供給ルートに着目してきたが、商用電力供給源、太陽光発電手段、蓄電手段の三者の関係について全体的なシステムとしての改良が不十分な点がある。例えば、上記のように複数の太陽光発電手段を準備する必要があり、また商用電力側への逆潮流を認める単一の太陽光発電手段を準備させた場合に停電などの異常状態が発生した場合には安全性の面から太陽光発電手段と商用電力供給源との電気的接続及び蓄電手段と商用電力供給源とのの電気的接続を遮断する必要があるが、その場合に上記のような関係としていた結果、太陽光発電手段と蓄電手段との電気的接続も遮断する構成となっていた。そのため、その状況では太陽光発電手段が生じる電力は蓄電手段に蓄えられることはなく、太陽光発電手段が生じる電力を利用できていないことが起こっている。   However, although attention has been paid to the supply route to the power consumption at the load as described above, the overall system improvement is insufficient regarding the relationship between the commercial power supply source, the solar power generation means, and the power storage means. There is a point. For example, it is necessary to prepare a plurality of solar power generation means as described above, and an abnormal state such as a power failure occurs when a single solar power generation means that allows reverse power flow to the commercial power side is prepared. In this case, it is necessary to cut off the electrical connection between the photovoltaic power generation means and the commercial power supply source and the electrical connection between the power storage means and the commercial power supply source from the viewpoint of safety. As a result, the electrical connection between the photovoltaic power generation means and the power storage means was also cut off. Therefore, in that situation, the power generated by the solar power generation means is not stored in the power storage means, and the power generated by the solar power generation means cannot be used.

ゆえに、本発明は、停電のような異常状態において、商用電力供給源とは異なる単一の太陽光発電手段のような発電源のみでシンプルな構成であって、この発電源と商用電力供給源との電気的接続及び蓄電手段と商用電力供給源との電気的接続が遮断されて上記発電源と蓄電手段との電気的接続も遮断される場合であっても、発電手段が発生する電力を有効利用可能とする電力貯蔵システム、並びにこのシステムに利用されるルート発生装置及びルート発生方法を提供することを目的とする。   Therefore, the present invention has a simple configuration with only a power generation source such as a single solar power generation means different from the commercial power supply source in an abnormal state such as a power failure, and the power generation source and the commercial power supply source Even when the electrical connection between the power generation means and the commercial power supply source is interrupted and the electrical connection between the power generation source and the power storage means is also interrupted, the electric power generated by the power generation means is reduced. An object of the present invention is to provide a power storage system that can be used effectively, and a route generation device and a route generation method used in this system.

次に、本発明の実施の形態に係る電力貯蔵システム１の動作について説明する。   Next, the operation of the power storage system 1 according to the embodiment of the present invention will be described.

まず、夜間電力の有効利用のために夜間料金適用時間帯を利用して商用電力供給源４００から蓄電池３０６に電力を充電する。同時に商用電力供給源４００から家庭内負荷１０４に電力の供給を行う。そして、電力会社４の受電電力量計４０４により、商用電力供給源４００から供給された電力量が計測される。   First, in order to effectively use nighttime power, power is charged from the commercial power supply source 400 to the storage battery 306 by using the nighttime charge application time zone. At the same time, power is supplied from the commercial power supply source 400 to the household load 104. Then, the amount of power supplied from the commercial power supply source 400 is measured by the received power meter 404 of the power company 4.

商用電力供給源４００から蓄電池３０６に電力を充電する場合は、商用電力供給源４００から経路ＲＴ６００を通り、接続点ＣＰ５００、経路ＲＴ６０２、接続点ＣＰ５０２、経路ＲＴ６０６、接続点ＣＰ５０４を経由して蓄電池３０６に電力が供給され、蓄電池３０６に電力が充電される。   When charging power from the commercial power supply source 400 to the storage battery 306, the storage battery 306 passes through the route RT600 from the commercial power supply source 400 and passes through the connection point CP500, the route RT602, the connection point CP502, the route RT606, and the connection point CP504. The power is supplied to the storage battery 306 and the power is charged.

同時に商用電力供給源４００から家庭内負荷１０４に電力を供給する場合は、商用電力供給源４００から経路ＲＴ６００を通り、接続点ＣＰ５００、経路ＲＴ６０２、接続点ＣＰ５０２、経路ＲＴ６０４、分電盤ＥＬＣＢ１１０、ブレーカー１０８、経路ＲＴ６１８を経由して、家庭内負荷１０４に電力が供給される。   At the same time, when power is supplied from the commercial power supply source 400 to the household load 104, the commercial power supply source 400 passes through the route RT600 and is connected to the connection point CP500, the route RT602, the connection point CP502, the route RT604, the distribution board ELCB110, and the breaker. 108, electric power is supplied to the household load 104 via the route RT618.

上記蓄電池３０６に充電された電力を利用して昼間の家庭内負荷１０４への電力の供給を行う。家庭内負荷１０４が３ｋＷ以下の場合は、蓄電池３０６からのみ家庭内負荷１０４への電力の供給が行われ、家庭内負荷１０４が３ｋＷ以上の場合は、不足分を太陽光発電パネル２００から補う。そして、太陽光発電パネル２００から補充された電力のうち家庭内負荷１０４への供給を超えた余剰分の電力は電力会社へ売電される。この売電電力量は、電力会社４の売電電力量計４０２により計測される。   The power supplied to the storage battery 306 is used to supply power to the home load 104 in the daytime. When the domestic load 104 is 3 kW or less, power is supplied only from the storage battery 306 to the domestic load 104, and when the domestic load 104 is 3 kW or more, the shortage is compensated from the photovoltaic power generation panel 200. Then, surplus power exceeding the supply to the household load 104 among the power supplemented from the solar power generation panel 200 is sold to the power company. The amount of power sold is measured by a power sales meter 402 of the power company 4.

なお、上記実施の形態では太陽光発電パネル２００から家庭内負荷１０４へ電力を補うか否かの判断を、家庭内負荷１０４が３ｋＷ以上か否かで判断しているが、この３ｋＷという数値は任意に設定または変更が可能である。   In the above embodiment, whether or not the solar power generation panel 200 supplements power to the home load 104 is determined based on whether or not the home load 104 is 3 kW or more. It can be set or changed arbitrarily.

蓄電池３０６から家庭内負荷１０４に電力を供給する場合は、蓄電池３０６から接続点ＣＰ５０４を通り、経路ＲＴ６０６、接続点ＣＰ５０２、経路ＲＴ６０４、分電盤ＥＬＣＢ１１０、ブレーカー１０８、経路ＲＴ６１８を経由して、家庭内負荷１０４に電力が供給される。   When power is supplied from the storage battery 306 to the household load 104, the storage battery 306 passes through the connection point CP504, passes through the route RT606, the connection point CP502, the route RT604, the distribution board ELCB110, the breaker 108, and the route RT618. Electric power is supplied to the internal load 104.

太陽光発電パネル２００から家庭内負荷１０４に電力を供給する場合は、太陽光発電パネル２００から経路ＲＴ６１６を通り、接続点ＣＰ５０８において「供給」側に接続している切替スイッチ１１６、経路ＲＴ６１４、接続点ＣＰ５００、経路ＲＴ６０２、接続点ＣＰ５０２、経路ＲＴ６０４、分電盤ＥＬＣＢ１１０、ブレーカー１０８、経路ＲＴ６１８を経由して、家庭内負荷１０４に電力が供給される。   When power is supplied from the photovoltaic power generation panel 200 to the household load 104, the selector switch 116, the path RT614, and the connection that are connected to the “supply” side at the connection point CP508 from the photovoltaic power generation panel 200 through the path RT616. Electric power is supplied to the home load 104 via the point CP500, the route RT602, the connection point CP502, the route RT604, the distribution board ELCB110, the breaker 108, and the route RT618.

太陽光発電パネル２００から電力会社４に電力を売電する場合は、接続点ＣＰ５００までは上記太陽光発電パネル２００から家庭内負荷１０４に電力を供給する場合と同様の経路を辿る。そして、接続点ＣＰ５００から経路ＲＴ６００を通り、受電電力量計４０４、売電電力量計４０２を経由して電力が売電される。   When selling power from the photovoltaic power generation panel 200 to the power company 4, the same route as that for supplying power from the photovoltaic power generation panel 200 to the home load 104 is followed up to the connection point CP500. Then, power is sold from the connection point CP 500 through the route RT 600 via the received power meter 404 and the sold power meter 402.

なお、例えば悪天候等により太陽光発電パネル２００による発電が行えない場合、蓄電池３０６からの供給だけでは家庭内負荷１０４に十分な電力を供給できない可能性がある。その場合は、商用電力供給源４００から家庭内負荷１０４へ電力が供給されることも可能となっている。   Note that, for example, when power generation by the solar power generation panel 200 cannot be performed due to bad weather or the like, there is a possibility that sufficient power cannot be supplied to the household load 104 only by supply from the storage battery 306. In that case, power can be supplied from the commercial power supply source 400 to the household load 104.

以上が正常状態での本発明の実施の形態に係る電力貯蔵システム１の動作である。次に災害等が起こって停電した場合の異常状態での電力貯蔵システム１の動作を説明する。   The above is the operation of the power storage system 1 according to the embodiment of the present invention in the normal state. Next, the operation of the power storage system 1 in an abnormal state when a power failure occurs due to a disaster or the like will be described.

災害が起こって停電等の異常状態が発生した場合、安全性の面から太陽光発電パネル２００と電力会社４との電気的接続及び蓄電部４と電力会社４との電気的接続を遮断する必要がある。すなわち、太陽光パワーコンディショナー１０６の太陽光ＰＣ連係スイッチ１１４とコントローラー３０２の蓄電連係スイッチ３１２が「切る」となり電気的接続が遮断される。   When a disaster occurs and an abnormal state such as a power failure occurs, it is necessary to cut off the electrical connection between the photovoltaic power generation panel 200 and the power company 4 and the electrical connection between the power storage unit 4 and the power company 4 from the viewpoint of safety. There is. That is, the solar power PC link switch 114 of the solar power conditioner 106 and the power storage link switch 312 of the controller 302 are “turned off”, and the electrical connection is cut off.

上記２箇所の連係が切断されると、家庭内負荷１０４への電力供給の経路は蓄電池３０６からの経路しか無く、太陽光発電パネル２００から生じる電力を利用できていなくなってしまう。そこで、本発明の実施の形態に係る電力貯蔵システム１では太陽光発電パネル２００と蓄電池３０６を接続する経路を確立できる構成とした。   If the two links are disconnected, the power supply path to the home load 104 is only the path from the storage battery 306, and the power generated from the solar power generation panel 200 cannot be used. Therefore, the power storage system 1 according to the embodiment of the present invention is configured to establish a path for connecting the photovoltaic power generation panel 200 and the storage battery 306.

異常状態が発生した場合に太陽光発電パネル２００と蓄電池３０６を接続するために、本発明の実施の形態に係る電力貯蔵システム１の構成は、切替スイッチ１１６と、電池ボックス３００に太陽光充電回路３０４を備える構成となっている。   In order to connect the photovoltaic power generation panel 200 and the storage battery 306 when an abnormal state occurs, the configuration of the power storage system 1 according to the embodiment of the present invention includes a changeover switch 116, a battery box 300, and a solar charging circuit. 304 is provided.

上記構成による異常状態が発生した場合の動作を説明する。   The operation in the case where an abnormal state with the above configuration occurs will be described.

まず、太陽光ＰＣ連係スイッチ１１４が「切る」となり、太陽光発電パネル２００から家庭内負荷へ電力を供給できなくなる。そこで、太陽光ＰＣ連係スイッチ１１４が「切る」となった事に連動して、接続点ＣＰ５０８における切替スイッチ１１６が「蓄電」側に自動で接続される。電力は、太陽光発電パネル２００から経路ＲＴ６１６を通り、接続点ＣＰ５０８、経路ＲＴ６１０、接続点ＣＰ５０６、経路ＲＴ６０８、太陽光充電回路３０４、接続点ＣＰ５０４を経由して、蓄電池３０６に充電される。この充電された電力は、蓄電池３０６から家庭内負荷１０４に電力を供給する場合の経路を辿って家庭内負荷１０４に供給される。   First, the solar PC link switch 114 is “turned off”, and power cannot be supplied from the solar power generation panel 200 to the home load. Therefore, the changeover switch 116 at the connection point CP508 is automatically connected to the “storage” side in conjunction with the solar PC link switch 114 being “turned off”. The electric power passes from the solar power generation panel 200 through the route RT616, and is charged to the storage battery 306 via the connection point CP508, the route RT610, the connection point CP506, the route RT608, the solar charging circuit 304, and the connection point CP504. The charged electric power is supplied to the home load 104 along a path when power is supplied from the storage battery 306 to the home load 104.

上記のように、異常状態が発生した場合に、太陽光発電パネル２００と蓄電部３とを電気的に接続する経路を確立することによって、太陽光発電パネル２００と太陽光パワーコンディショナー１０６と蓄電部３とを一体的に捉えることができ、太陽光発電パネル２００で発生した電力を、蓄電部３を介して有効的に活用することができる。   As described above, when an abnormal state occurs, the solar power generation panel 200, the solar power conditioner 106, and the power storage unit are established by establishing a path for electrically connecting the solar power generation panel 200 and the power storage unit 3. 3 can be captured integrally, and the electric power generated by the photovoltaic power generation panel 200 can be effectively utilized via the power storage unit 3.

なお、太陽光パワーコンディショナー１０６が有する非常用端子１１８と蓄電部３とを電気的に接続する経路を確立することで、太陽光発電パネル２００で発生した電力を充電できるようにしてもよい。   In addition, you may enable it to charge the electric power which generate | occur | produced in the photovoltaic power generation panel 200 by establishing the path | route which electrically connects the emergency terminal 118 and the electrical storage part 3 which the solar power conditioner 106 has.

さらに、上記実施の形態では異常状態発生時の電力会社との遮断箇所を太陽光ＰＣ連係スイッチ１１４と蓄電連係スイッチ３１２としたが、例えば接続点ＣＰ５００とＡＣＬ１１２の間に新たなスイッチを設けて、そこを遮断箇所にすることにより、蓄電部３及び太陽光発電パネル２００の双方からの電力の供給が可能となり、太陽光発電パネル２００で発生した電力を直接家庭内負荷１０４に供給することも可能となる。このように、停電のような異常状態が発生した場合の太陽光発電パネル２００により発生した電力と蓄電池３０６の電力との関係を、太陽光パワーコンディショナー１０６とコントローラー３０２とを一体的な制御部として再構成してもよい。   Furthermore, in the above embodiment, the solar PC link switch 114 and the power storage link switch 312 are used as the shutoff points from the electric power company when an abnormal condition occurs. For example, a new switch is provided between the connection point CP500 and the ACL 112. By making this a blocking location, it is possible to supply power from both the power storage unit 3 and the photovoltaic power generation panel 200, and it is also possible to supply the power generated by the photovoltaic power generation panel 200 directly to the household load 104. It becomes. As described above, the relationship between the power generated by the photovoltaic power generation panel 200 and the power of the storage battery 306 when an abnormal state such as a power failure occurs is obtained by using the solar power conditioner 106 and the controller 302 as an integrated control unit. It may be reconfigured.

さらに、上記実施の形態では太陽光発電パネル２００で発生した電力を電力会社４へ売電可能としたが必ずしも売電される必要はない。例えば日中では売電モードと蓄電モードを選択可能とし、通常状態の時であっても切替スイッチ１１６を操作することにより「蓄電」側への切替を可能とすることにより、家庭内負荷１０４による電力消費の優先順位の一番目を太陽光発電パネル２００からの電力としつつ、蓄電池３０６に電力を充電できるようにしてもよい。   Furthermore, although the electric power generated in the photovoltaic power generation panel 200 can be sold to the electric power company 4 in the above embodiment, it is not necessarily sold. For example, the power sale mode and the power storage mode can be selected during the daytime, and even when in the normal state, the switch to the “power storage” side can be performed by operating the changeover switch 116. You may enable it to charge electric power to the storage battery 306, making electric power from the photovoltaic power generation panel 200 the 1st priority of electric power consumption.

さらに、上記実施の形態では電池ボックス３００内に太陽光充電回路３０４を設置して、異常状態発生時に蓄電池３０６への蓄電を行うこととしたが、太陽光パワーコンディショナー１０６内に、太陽光発電パネル２００からの電力を調整する電力調整器、正常状態時にＡＣ出力を行うためのＤＣ／ＡＣコントローラー及び異常状態発生時に蓄電池３００に電力を蓄電するための充電機能を有するＤＣ／ＤＣコントローラーを設けることで、電池ボックス３００内に太陽光充電回路３０４を設置しなくても、異常状態発生時に蓄電池３０６へ電力が蓄電できるようにしてもよい。   Furthermore, in the above-described embodiment, the solar battery charging circuit 304 is installed in the battery box 300 to store electricity in the storage battery 306 when an abnormal state occurs. However, in the solar power conditioner 106, the solar power generation panel By providing a power regulator for adjusting power from 200, a DC / AC controller for performing AC output in a normal state, and a DC / DC controller having a charging function for storing power in the storage battery 300 when an abnormal state occurs Even if the solar battery charging circuit 304 is not installed in the battery box 300, electric power may be stored in the storage battery 306 when an abnormal state occurs.

さらに、上記実施の形態では商用電力供給源とは異なる発電源を太陽光としたが、太陽光以外に風力等の自然エネルギーを利用した発電源であってもよい。   Furthermore, although the power generation source different from the commercial power supply source is sunlight in the above-described embodiment, it may be a power generation source using natural energy such as wind power in addition to sunlight.

さらに、上記実施の形態では異常状態を災害等による停電としたが、電力会社４内部の機器の故障または接続の遮断等が原因による異常状態であってもよい。   Furthermore, although the abnormal state is a power failure due to a disaster or the like in the above embodiment, it may be an abnormal state due to a failure of a device in the electric power company 4 or a disconnection of a connection.
