Description

本発明は、電力需要家内に設置され、商用電力からの供給電力を計測し、供給電力に応じて課金を行う受電システムに関わるものである。   The present invention relates to a power receiving system that is installed in a power consumer, measures the power supplied from commercial power, and charges according to the power supplied.

従来の受電システムの構成を図３に示す。従来の受電システムは、電気事業者、電力再販業者１１が提供する商用電源１０と需要家２１に設置される電力計２０からなる。従来の受電システムの動作は以下である。   A configuration of a conventional power receiving system is shown in FIG. The conventional power receiving system includes a commercial power source 10 provided by an electric power company and a power reseller 11 and a wattmeter 20 installed in a consumer 21. The operation of the conventional power receiving system is as follows.

商用電源１０からは需要家２１の負荷に必要な電力を需要家２１に供給する。電力計２０は需要家２１への供給電力量を計測する。電力計２０が計測した供給電力量そのもの、もしくは、供給電力量に基づいた課金データＳ２２は、例えば担当員の目視による計測や、通信手段を用いて自動的に電気事業者、電力再販業者１１に送られ、需要家２１に対して課金される。   The commercial power supply 10 supplies the customer 21 with power necessary for the load of the customer 21. The wattmeter 20 measures the amount of power supplied to the consumer 21. The power supply amount itself measured by the wattmeter 20 or the billing data S22 based on the power supply amount is automatically measured by a person in charge, for example, automatically by the electric power company or the power reseller 11 using communication means. Sent to the customer 21 and charged.

従来の受電システムにより、商用電源から需要家への供給電力量に応じた課金が可能である。しかしながら、受電システムには以下のような問題点がある。   With a conventional power receiving system, it is possible to charge according to the amount of power supplied from a commercial power source to a consumer. However, the power receiving system has the following problems.

第一に従来の受電システムでは、電力の需給状態によらず常に一定の価格にて課金される構成であるため、例えば深夜など電力の供給に余裕があり、低価格にて電力を供給できる場合にも需要家は通常料金にて電力を購入することを余儀なくされ、結果的に需要家の電力購入コストが上昇するという問題がある。   First, the conventional power receiving system is configured to always charge at a fixed price regardless of the supply and demand status of power. For example, when there is a margin for power supply such as late at night and power can be supplied at a low price In addition, there is a problem that the consumer is forced to purchase the electric power at a normal charge, and as a result, the electric power purchase cost of the consumer increases.

第二に、電気事業者は電力需要量と供給量を同時に同量にする責務を負っているが、従来の受電システムでは例えば夏場の日中など需要家への供給量が一時的に非常に大きくなった場合に備えて調整用の電源を準備する必要があり、発電施設の建設コストや高価格な調整電力の購入などが必要で、結果的に電力価格の高騰を招くという問題がある。   Secondly, the electric utility is responsible for making the power demand and supply the same amount at the same time, but in the conventional power receiving system, for example, during the summer day, the supply to the customer is temporarily very low. There is a problem that it is necessary to prepare a power supply for adjustment in preparation for an increase in size, and it is necessary to construct a power generation facility, purchase expensive adjustment power, and the like, resulting in an increase in power price.

第三に、商用電源の内、水力、風力発電など自然エネルギー起源の発電や、場合によっては原子力発電などは、ＣＯ2の排出原単位が少なく、環境性の高い電源といえるが、従来の受電システムを用いた場合には、電気事業者の発電状態に関わらず、需要家の電力需要が発生するため、ＣＯ2の排出原単位の高い火力の調整電源の稼動が多くなり、結果的にＣＯ2の排出量が多くなり、環境に悪影響を及ぼすという問題もある。 Third, among the commercial power source, hydroelectric power generation and natural energy sources such as wind power, in some cases, such as nuclear power generation, less emission intensity of CO 2, but it can be said that high environmental resistance power, conventional power receiving When the system is used, regardless of the power generation state of the electric utility, the demand for power from the customer is generated, so that the operation of the thermal power adjustment power source with a high CO 2 emission intensity increases. There is also a problem that the amount of emissions of 2 increases, which has an adverse effect on the environment.

本発明は上述した従来の技術が有する問題点に鑑みてなされたものであって、電力の供給を効率よく行い、また、使用状態に応じた課金が行われる受電システムを実現することを目的とする。   The present invention has been made in view of the above-described problems of the prior art, and aims to realize a power receiving system that efficiently supplies power and charges according to the use state.

次に、本発明による実施例について図面を参照して説明する。   Next, embodiments of the present invention will be described with reference to the drawings.

図１は本発明による蓄電機能付き受電システムの一実施例の構成を示すブロック図、図２は図１に示した実施例の動作状態を示す図である。   FIG. 1 is a block diagram showing a configuration of an embodiment of a power receiving system with a storage function according to the present invention, and FIG. 2 is a diagram showing an operation state of the embodiment shown in FIG.

本実施例の蓄電機能付き受電システムは、商用電源の供給元である電気事業者、電力再販業者１０１が提供する商用電源１００と需要家２０１に設置される電力計２００からなる。需要家２０１には、電力計２００、充放電装置３０、蓄電装置４０、監視制御装置５０が設けられる。監視制御装置５０は、充放電制御器５１、課金装置５２、状態監視器５３及び状態表示装置５４からなる。本実施例における蓄電機能付き受電システムの動作は以下である。   The power receiving system with a power storage function according to the present embodiment includes a commercial power source 100 provided by an electric power company and a power reseller 101 as a commercial power source, and a wattmeter 200 installed in a consumer 201. The consumer 201 is provided with a power meter 200, a charge / discharge device 30, a power storage device 40, and a monitoring control device 50. The monitoring control device 50 includes a charge / discharge controller 51, a charging device 52, a state monitor 53, and a state display device 54. The operation of the power receiving system with a power storage function in the present embodiment is as follows.

需要家２０１に対して電力を供給する商用電源１００は、電力の需給の状態が余剰状態で通常より安価に供給できる状態である、電力が不足している状態で、需要家の負荷規制など、需要を減らすことが望ましい状態であるなどの電力の需給状態についての情報を電力供給状態Ｓ３０５として需要家２０１に提供する。   The commercial power supply 100 that supplies power to the customer 201 is in a state where the supply and demand state of power is in a surplus state and can be supplied at a lower cost than usual, in a state where power is insufficient, load regulation of the customer, etc. Information about the supply and demand state of power, such as a state where it is desirable to reduce demand, is provided to the consumer 201 as a power supply state S305.

電力計２００は、商用電源１００、もしくは、蓄電池４０から充放電装置３０を介して需要家内の負荷に供給される供給電力量を計測し、供給電力量Ｓ３０４として監視制御装置５０に出力する。   The wattmeter 200 measures the amount of power supplied from the commercial power source 100 or the storage battery 40 to the load in the consumer via the charging / discharging device 30, and outputs the measured amount of power to the monitoring control device 50 as the amount of power supplied S304.

充放電装置３０は監視制御装置５０からの充放電指令Ｓ３０１に基づき、商用電源１００から蓄電装置４０への充電あるいは蓄電装置４０から需要家２０１の負荷への放電量を任意に調整する。   The charge / discharge device 30 arbitrarily adjusts the amount of charge from the commercial power supply 100 to the power storage device 40 or the discharge from the power storage device 40 to the load of the consumer 201 based on the charge / discharge command S301 from the monitoring control device 50.

蓄電装置４０は充放電装置３０により制御され、商用電源１００から送られる電力を蓄積する機能と、蓄積された電力を放電する機能を有するとともに、「蓄電装置４０が満充電でこれ以上電力を充電できない状態である」、「満充電ではなくさらに電力を充電できる状態である」、「蓄電装置４０の内部に電力が蓄えられており、放電により電力供給が可能な状態である」、「蓄電装置４０に全く電力が蓄積されておらず、放電が不可能な状態である」などの充電状態Ｓ３０２を監視制御装置５０に出力する機能を有する。   The power storage device 40 is controlled by the charge / discharge device 30 and has a function of accumulating electric power sent from the commercial power supply 100 and a function of discharging the accumulated electric power. Is in a state incapable of being charged, "is not in full charge, but is in a state in which more power can be charged," "power is stored in the power storage device 40, and power can be supplied by discharging", "power storage device 40 has a function of outputting a charging state S302 such as “no electric power is stored in 40 and discharging is impossible” to the monitoring control device 50.

状態監視器５３は商用電源１００から入力された電力需給状態Ｓ３０５と蓄電装置４０から入力された充電状態Ｓ３０２をとりまとめ、システム状態Ｓ３０３として充放電制御器５１、課金装置５２、状態表示装置５４に出力する。   The state monitor 53 collects the power supply / demand state S305 input from the commercial power supply 100 and the charge state S302 input from the power storage device 40, and outputs them as a system state S303 to the charge / discharge controller 51, the charging device 52, and the state display device 54. To do.

充放電制御器５１及び課金装置５２には、電力計２００及び状態監視器５３から供給電力量Ｓ３０４とシステム状態Ｓ３０３がそれぞれ入力される。これらの入力に応じて、充放電制御器５１は充放電装置３０への充放電指令Ｓ３０１を出力し、課金装置５２は電気事業者、電力販売業者１０１へ課金データＳ３０６を出力する。   The charge / discharge controller 51 and the billing device 52 are supplied with the supplied power amount S304 and the system state S303 from the power meter 200 and the state monitor 53, respectively. In response to these inputs, the charging / discharging controller 51 outputs a charging / discharging command S301 to the charging / discharging device 30, and the charging device 52 outputs charging data S306 to the electric power company and the power seller 101.

充放電制御器５１及び課金装置５２の具体的動作について図３を参照し、以下に説明する。   Specific operations of the charge / discharge controller 51 and the charging device 52 will be described below with reference to FIG.

電力需給状態が、電力供給力に余裕のある余剰状態であり、かつ蓄電装置４０の状態が、満充電でこれ以上充電が不可能な場合（状態Ｎｏ１）には、充放電制御器５１は、充放電装置３０を停止、もしくは、蓄電装置４０の補充電のみを行う旨の充放電指令Ｓ３０１を充放電装置３０へ出力する。   When the power supply / demand state is a surplus state with sufficient power supply capacity and the state of the power storage device 40 is fully charged and cannot be further charged (state No1), the charge / discharge controller 51 The charge / discharge device 30 is output to the charge / discharge device 30 to stop the charge / discharge device 30 or to perform only the auxiliary charge of the power storage device 40.

また、課金装置５２は、供給電力量あたりの電力料金としては、通常より安い割引料金を適用して計算した課金データＳ３０６を電気事業者、電力販売業者１０１へ出力する。   In addition, the billing device 52 outputs billing data S306 calculated by applying a discount fee cheaper than usual as the power bill per supplied power amount to the electric power company and the power seller 101.

電力需給状態が、余剰状態でありかつ蓄電装置４０の状態が、満充電ではなくさらに充電が可能な場合（状態Ｎｏ２）には、充放電制御器５１は、充放電装置３０により蓄電装置４０が最も効率よく充電を行える条件での充電を行う旨の充放電指令Ｓ３０１を充放電装置３０へ出力する。   When the power supply and demand state is a surplus state and the state of the power storage device 40 is not fully charged but can be further charged (state No2), the charge / discharge controller 51 causes the power storage device 40 to be connected by the charge / discharge device 30. A charge / discharge command S301 is output to the charge / discharge device 30 to charge the battery under the most efficient charge condition.

また、課金装置５２は、供給電力量あたりの電力料金として、通常より安い割引料金を適用して計算した課金データＳ３０６を電気事業者、電力販売業者１０１へ出力する。   In addition, the billing device 52 outputs billing data S306 calculated by applying a discount fee cheaper than usual as the power bill per supplied power amount to the electric power company and the power seller 101.

電力需給状態が、電力供給力に余裕がなく、需要家の消費電力を削減することが望ましい不足状態であるものの、蓄電装置４０の状態が、内部に電力が蓄えられており、放電が可能な場合（状態Ｎｏ３）には、充放電制御器５１は、充放電装置３０により需要家２０１への供給電力と等しい量の電力が充放電装置３０を介して需要家２０１へ供給されるように蓄電装置４０の放電を行う旨の充放電指令Ｓ３０１を充放電装置３０へ出力する。   Although the power supply / demand state is a shortage state where it is desirable to reduce the power consumption of the consumer because the power supply capacity is not sufficient, the power storage device 40 is in a state where electric power is stored and discharge is possible. In the case (state No. 3), the charging / discharging controller 51 stores power so that the charging / discharging device 30 supplies an amount of power equal to the power supplied to the customer 201 to the customer 201 via the charging / discharging device 30. A charge / discharge command S301 for discharging the device 40 is output to the charge / discharge device 30.

また、課金装置５２は、供給電力量あたりの電力料金としては、通常より安い割引料金を適用して計算した課金データＳ３０６を電気事業者、電力販売業者１０１へ出力する。   In addition, the billing device 52 outputs billing data S306 calculated by applying a discount fee cheaper than usual as the power bill per supplied power amount to the electric power company and the power seller 101.

電力需給状態が、状態Ｎｏ３と同様に不足状態であり、かつ蓄電装置４０の状態が、内部に電力が蓄えられておらず、放電が不可能な場合（状態Ｎｏ４）には、充放電制御器５１は、充放電装置３０の動作を停止し、蓄電装置４０の放電を停止する旨の充放電指令Ｓ３０１を充放電装置３０へ出力する。   When the power supply / demand state is insufficient as in the case of state No. 3 and the state of the power storage device 40 does not store electric power and cannot be discharged (state No. 4), the charge / discharge controller 51 stops the operation of the charging / discharging device 30 and outputs a charging / discharging command S301 to stop the discharging of the power storage device 40 to the charging / discharging device 30.

また、課金装置５２は、供給電力量あたりの電力料金としては、通常の料金を適用して計算した課金データＳ３０６を電気事業者、電力販売業者１０１へ出力する。   In addition, the billing device 52 outputs billing data S306 calculated by applying a normal charge to the electric power company and the power seller 101 as the power charge per supplied power amount.

状態表示装置５４は状態監視器５３から入力された電力需給の状態や充電状態を表示することにより、需要家に情報を提供する。   The status display device 54 provides information to the consumer by displaying the power supply / demand status and the charging status input from the status monitor 53.

なお、以上説明した実施例では、監視制御装置５０が需要家２０１側にある場合について説明したが、監視制御装置５０を電気事業者、電力再販業者１０１側に設ける構成としてもよい。このような構成とした場合、監視制御装置５０から充放電装置３０への充放電指令Ｓ３０１や、蓄電装置４０から監視制御装置５０への充電状態Ｓ３０２のやり取りは、有線または無線による通信やインターネットなどのネットワーク接続を用いて行うことができる。   In the above-described embodiment, the case where the monitoring control device 50 is on the consumer 201 side has been described. However, the monitoring control device 50 may be provided on the electric power company / power reseller 101 side. In the case of such a configuration, the charge / discharge command S301 from the monitoring control device 50 to the charging / discharging device 30 and the exchange of the charging state S302 from the power storage device 40 to the monitoring control device 50 are performed via wired or wireless communication, the Internet, etc. This can be done using any network connection.

また、電力計２００は、需要家２０１側に設けられるものとして説明したが、電気事業者、電力再販業者１０１側に設ける構成としてもよい。このような構成とした場合、電力計２００から監視制御装置５０への供給電力量Ｓ３０４のやり取りは、有線または無線による通信やインターネットなどのネットワーク接続を用いて行うことができる。   Moreover, although the power meter 200 was demonstrated as what is provided in the consumer 201 side, it is good also as a structure provided in the electric power company and the electric power reseller 101 side. In such a configuration, the exchange of the supplied power amount S304 from the wattmeter 200 to the monitoring control device 50 can be performed using wired or wireless communication or network connection such as the Internet.

また、商用電源１００から蓄電装置４０への充電あるいは蓄電装置４０から需要家２０１の負荷への放電量は、充放電装置３０が監視制御装置５０（充放電制御器５１）からの充放電指令Ｓ３０１に基づいて調整するものとして説明したが、充放電制御器５１が直接制御を行うこととしてもよい。   Further, the charge / discharge device 30 charges / discharges commands S301 from the monitoring control device 50 (charge / discharge controller 51) with respect to the amount of charge from the commercial power source 100 to the power storage device 40 or the amount of discharge from the power storage device 40 to the load of the customer 201. However, the charge / discharge controller 51 may perform direct control.

上記のように構成される本実施例においては、電力の需給状態により、割引価格を適用して課金される構成であるため、例えば深夜など電力の供給に余裕があり、低価格にて電力を供給できる場合は需要家は安く電力を購入することが可能となる。   In the present embodiment configured as described above, since it is configured to be charged by applying a discount price depending on the supply and demand state of power, for example, there is a margin in power supply such as late at night, and power is supplied at a low price. If it can be supplied, the consumer can purchase electricity at a low price.

さらに、割引価格の時間帯に余剰電力を蓄えることができ、蓄電池に電力が蓄えられている限りにおいては需要家は安く電力を購入することが可能で、結果的に需要家の電力購入コストを安くできるという効果がある。   In addition, surplus power can be stored during the discounted price period, and as long as power is stored in the storage battery, consumers can purchase power cheaply, resulting in a reduction in the power purchase cost of consumers. It has the effect of being cheap.

また、本実施例によれば、例えば夏場の日中など需要家への供給量が一時的に非常に大きくなった場合には、蓄電装置に蓄えた電力により、需要家個々に電力を調整することが可能であり、電気事業者としては調整用の電源を準備する必要がなくなるため、発電施設の建設コストや高価格な調整電力の購入などが不要となる。結果的に電力価格全体を安くできるという効果も生じる。   Further, according to this embodiment, for example, when the supply amount to the customer temporarily becomes very large such as during the daytime in summer, the electric power is adjusted individually for each consumer by the electric power stored in the power storage device. This eliminates the need for an electric power company to prepare a power source for adjustment, thus eliminating the need to construct a power generation facility or purchase expensive adjusted power. As a result, there is an effect that the overall power price can be reduced.

さらに、電気事業者の電力需給状態に応じて需要家への電力供給量を調整できるためＣＯ2の排出原単位の高い火力の調整電源の稼動を抑えることができ、結果的にＣＯ2の排出量が削減でき、環境への悪影響を低減できる。 In addition, since the amount of power supplied to consumers can be adjusted according to the electricity supplier's power supply and demand situation, it is possible to suppress the operation of a regulated power source with high CO 2 emission intensity, resulting in CO 2 emissions. The amount can be reduced, and adverse effects on the environment can be reduced.

また、需要家は蓄電装置の充電状態や電力需給の状態を容易に知ることができるため、電力が不足している場合や、蓄電装置の充電量が少ない場合には自主的に電力消費を減らす努力を行うことができ、全体としての電力消費の抑制や電力消費のピークシフトも可能となる。   In addition, since consumers can easily know the state of charge of power storage devices and the state of power supply and demand, they can voluntarily reduce power consumption when power is insufficient or when the amount of charge of power storage devices is low. Efforts can be made, and overall power consumption can be reduced and peak power consumption can be shifted.
