Description

電力需給を調整するシステム、電力需給を調整するための電気事業者設備、電力需給を調整するための需要家設備および電力需給を調整する方法A system for adjusting power supply and demand, an electric utility facility for adjusting power supply and demand, a customer facility for adjusting power supply and demand, and a method for adjusting power supply and demand
　本発明は、電力需給の調整に関し、特に、電力需給を調整するシステム、電力需給を調整するための電気事業者設備、電力需給を調整するための需要家設備および電力需給を調整する方法に関する。 The present invention relates to power supply and demand adjustment, and more particularly, to a system for adjusting power supply and demand, an electric utility facility for adjusting power supply and demand, a customer facility for adjusting power supply and demand, and a method for adjusting power supply and demand.
　電力の需要は、時間によって変化する。電気事業者は、電力の需要のピークが到来した場合においても電力を安定して供給できるように発電設備、送配電設備等を準備する必要がある。このため、電気事業者により準備される発電設備、送配電設備等を縮小するためには、電力の需要のピークを抑制するピークカットが必要である。ピークカットは、電力の需要のピークが属する時間帯における電力消費の削減を需要家に動機付けることにより行われる場合もあるし、電力の需要のピークが属する時間帯における電力消費を当該時間帯以外の時間帯へ移動することにより行われる場合もある。 Demand for power changes with time.

　電力の需要に無駄な電力消費が含まれる場合にピークカットが行われたときは、電力の需要のピークが属する時間帯における無駄な電力消費が削減され、当該時間帯以外の時間帯に新たな電力の需要のピークを発生させることなく、電力の需要のピークが抑制される。 When a peak cut is performed when wasteful power consumption is included in the power demand, wasteful power consumption in the time zone to which the peak of power demand belongs is reduced, and a new time zone other than the time zone is added. The peak of power demand is suppressed without causing the peak of power demand.
　しかし、電力の需要に無駄な電力消費が含まれない場合にピークカットが行われたときは、電力の需要のピークが属する時間帯における電力消費が削減され電力の需要のピークが抑制されるが、当該時間帯以外の時間帯における電力消費が増加し新たな電力の需要のピークが発生する可能性がある。電力の需要のシフト先の時間帯は、需要家の間で共通する可能性が高いからである。例えば、需要家が一般家庭である場合は、消費電力は生活リズムとなるため、似通よった傾向が現れる。 However, when peak cut is performed when wasteful power consumption is not included in the power demand, power consumption in the time zone to which the power demand peak belongs is reduced and the peak of power demand is suppressed. There is a possibility that power consumption in a time zone other than the time zone will increase and a new demand peak for power will occur. This is because the time zone to which the demand for power is shifted is likely to be common among consumers. For example, when the consumer is a general household, the power consumption becomes a daily rhythm, so a similar tendency appears.

　４　需要家の消費電力の時間変化
　図２，３および４の各々は、需要家の消費電力の時間変化の例を示すグラフである。図５は、需要家の消費電力の時間変化および電気事業者から供給される供給電力の上限の例を示すグラフである。 4. Time Change of Consumer Power Consumption Each of FIGS. 2, 3 and 4 is a graph showing an example of time change of consumer power consumption. FIG. 5 is a graph showing an example of a change in power consumption of a consumer over time and an upper limit of supply power supplied from an electric power company.
　図２，３，４および５の各々は、需要家１２４２，１２４４および１２４６の各々が一般家庭である場合の例を示す。 2, 3, 4 and 5 show examples in which each of the consumers 1242, 1244 and 1246 is a general household.
　図２，３および４にそれぞれ示される需要家１２４２，１２４４および１２４６の消費電力の時間変化は、互いに類似する。このため、図５に示されるように、需要家１２４２，１２４４および１２４６の消費電力の合計は、２０時から２１時までの時間帯にピークを有し、２０時から２１時までの時間帯において電気事業者から供給される供給電力の上限を超過する。２０時から２１時までの時間帯における需要家１２４２，１２４４および１２４６の消費電力の合計と電気事業者から供給される供給電力の上限との差である超過分は、需要家１２４２，１２４４および１２４６の全部または一部に電力消費を削減することに対する見返りを与えることにより解消される可能性がある。見返りは、例えば、オークション形式により与えられる。しかし、見返りを与えることにより超過分が解消された場合は、需要家１２４２，１２４４および１２４６の消費電力の合計が２０時から２１時までの時間帯以外の時間帯にピークを有するようになる可能性がある。 The temporal changes in power consumption of the consumers 1242, 1244 and 1246 shown in FIGS. 2, 3 and 4 are similar to each other. Therefore, as shown in FIG. 5, the total power consumption of the consumers 1242, 1244 and 1246 has a peak in the time zone from 20:00 to 21:00, and in the time zone from 20:00 to 21:00 Exceeds the upper limit of power supplied from the electric utility. The excess, which is the difference between the total power consumption of the consumers 1242, 1244 and 1246 in the time zone from 20:00 to 21:00 and the upper limit of the supply power supplied from the electric utility, is the customers 1242, 1244 and 1246. May be eliminated by giving a reward for reducing power consumption to all or part of the power consumption. The reward is given, for example, in an auction format. However, if the excess is resolved by giving a reward, the total power consumption of the consumers 1242, 1244 and 1246 may have a peak in a time zone other than the time zone from 20:00 to 21:00. There is sex.
　需要家１２４２，１２４４および１２４６の各々が一般家庭でない場合も、需要家１２４２，１２４４および１２４６の消費電力の合計がピークを有する時間帯が需要家１２４２，１２４４および１２４６の各々が一般家庭である場合のそれとは異なる可能性があるが、同様のことが言える。 Even when each of the consumers 1242, 1244 and 1246 is not a general household, when the total of the power consumption of the consumers 1242, 1244 and 1246 has a peak, each of the consumers 1242, 1244 and 1246 is a general household The same can be said, though it may be different.
　５　蓄電池の充放電の制御
　電力需給を調整するシステム１０００においては、需要家１２４２，１２４４および１２４６の消費電力の合計がピークを迎える時間帯に蓄電池１０６２，１０８２および１１０２から需要家１２４２，１２４４および１２４６に電力が供給され、電力の需要のピークが抑制される。また、蓄電池１０６２，１０８２および１１０２が充電される時間帯が分散され、蓄電池１０６２，１０８２および１１０２の充電が新たな電力の需要のピークを発生させないようにされる。以下では、この点について具体例を参照しながら説明する。 5 Control of Charge / Discharge of Storage Battery In the system 1000 that adjusts the supply and demand of electric power, the consumer 1242, 1244 and 1246 from the storage batteries 1062, 1082 and 1102 during the time when the total power consumption of the consumers 1242, 1244 and 1246 reaches a peak. Electric power is supplied to the power supply, and the peak of power demand is suppressed. In addition, the time periods during which the storage batteries 1062, 1082 and 1102 are charged are dispersed, so that charging of the storage batteries 1062, 1082 and 1102 does not cause a new demand peak for power. Hereinafter, this point will be described with reference to a specific example.
　図６は、需要家の消費電力の時間変化、蓄電池から需要家に供給される供給電力の時間変化および電気事業者から供給される供給電力の上限の目標の例を示すグラフである。図７は、蓄電池の放電電力および充電電力の時間変化ならびに蓄電池の充電が禁止される時間帯の例を示すグラフである。図８は、電気事業者から供給される供給電力の時間変化の例を示すグラフである。 FIG. 6 is a graph showing an example of the target of the time change of the power consumption of the consumer, the time change of the supply power supplied from the storage battery to the consumer, and the upper limit of the supply power supplied from the electric utility. FIG. 7 is a graph showing an example of a time change in the discharge power and charge power of the storage battery and a time zone in which the charge of the storage battery is prohibited. FIG. 8 is a graph showing an example of the change over time of the supplied power supplied from the electric power company.
　図６に示される電気事業者から供給される供給電力の上限の目標は、電気事業者が供給できる供給電力の上限を示す。電気事業者から供給される供給電力の上限の目標を低下させることができた場合は、電気事業者が準備しなければならない発電設備、送配電設備等を縮小することができる。 The target of the upper limit of power supplied from the electric power company shown in FIG. 6 indicates the upper limit of power supplied by the electric power company. When the target of the upper limit of the supply power supplied from the electric power company can be reduced, the power generation facilities, power transmission / distribution facilities, etc. that the electric power company must prepare can be reduced.
　需要家１２４２，１２４４および１２４６の消費電力が図６に示されるものである場合は、７時から８時までの時間帯、１９時から２０時までの時間帯、２０時から２１時までの時間帯および２１時から２２時までの時間帯の各々において、需要家１２４２，１２４４および１２４６の消費電力の合計が電気事業者から供給される供給電力の上限の目標を超過する。 When the power consumption of the customers 1242, 1244 and 1246 is as shown in FIG. 6, the time zone from 7 o'clock to 8 o'clock, the time zone from 19 o'clock to 20 o'clock, the time from 20 o'clock to 21 o'clock In each of the time zone and the time zone from 21:00 to 22:00, the total power consumption of the consumers 1242, 1244 and 1246 exceeds the target of the upper limit of the supplied power supplied from the electric power company.
　しかし、図６に示されるように、７時から８時までの時間帯および１９時から２０時までの時間帯の各々には、蓄電池１１０２から需要家１２４６に電力が供給されるように個別放電制御部１１４６による制御が行われ、超過分が解消される。また、２０時から２１時までの時間帯および２１時から２２時までの時間帯の各々には、蓄電池１０６２から需要家１２４２に電力が供給されるように個別放電制御部１１４２による制御が行われ、蓄電池１０８２から需要家１２４４に電力が供給されるように個別放電制御部１１４４による制御が行われ、超過分が解消される。 However, as shown in FIG. 6, in each of the time zone from 7 o'clock to 8 o'clock and the time zone from 19 o'clock to 20 o'clock, individual discharge is performed so that power is supplied from the storage battery 1102 to the consumer 1246. Control by the control unit 1146 is performed, and the excess is eliminated. In addition, in each of the time zone from 20:00 to 21:00 and the time zone from 21:00 to 22:00, the individual discharge control unit 1142 performs control so that power is supplied from the storage battery 1062 to the consumer 1242. The individual discharge control unit 1144 performs control so that power is supplied from the storage battery 1082 to the consumer 1244, and the excess is eliminated.
　その結果として、図７に示されるように、７時から８時までの時間帯および１９時から２０時までの時間帯の各々に蓄電池１１０２が放電させられ、２０時から２１時までの時間帯および２１時から２２時までの時間帯の各々に蓄電池１０６２および蓄電池１０８２の各々が放電させられる。 As a result, as shown in FIG. 7, the storage battery 1102 is discharged in each of the time zone from 7 o'clock to 8 o'clock and the time zone from 19 o'clock to 20 o'clock, and the time zone from 20 o'clock to 21 o'clock Each of storage battery 1062 and storage battery 1082 is discharged in each of the time zones from 21:00 to 22:00.
　このように放電させられた蓄電池１０６２，１０８２および１１０２は、充電されなければならない。このため、図７に示されるように、１時から２時までの時間帯には、商用電源１２６２により蓄電池１１０２が充電されるように個別充電制御部１１６６による制御が行われる。また、２時から３時までの時間帯には、商用電源１２６２により蓄電池１０８２が充電されるように個別充電制御部１１６４による制御が行われる。また、３時から４時までの時間帯には、商用電源１２６２により蓄電池１０６２が充電されるように個別充電制御部１１６２による制御が行われる。より一般的には、蓄電池１０６２，１０８２および１１０２の各々である各蓄電池が充電される時間帯が蓄電池１０６２，１０８２および１１０２のうちの各蓄電池以外の充電池が充電される時間からずれるように各蓄電池の充電を制御する個別充電制御部により各蓄電池の充電が制御される。これにより、蓄電池１０６２，１０８２および１１０２が充電される時間帯が分散させられる。したがって、図７に示されるように、蓄電池１１０２が充電される１時から２時までの時間帯に蓄電池１０８２が充電されることはない。 The storage batteries 1062, 1082 and 1102 discharged in this way must be charged. Therefore, as shown in FIG. 7, during the time period from 1 o'clock to 2 o'clock, the individual charge control unit 1166 performs control so that the storage battery 1102 is charged by the commercial power source 1262. In the time zone from 2 o'clock to 3 o'clock, control by the individual charge control unit 1164 is performed so that the storage battery 1082 is charged by the commercial power source 1262. In the time zone from 3 o'clock to 4 o'clock, the individual charging control unit 1162 performs control so that the storage battery 1062 is charged by the commercial power source 1262. More generally, each of the storage batteries 1062, 1082 and 1102 is charged so that the time zone in which each storage battery is charged deviates from the time in which the rechargeable batteries other than each of the storage batteries 1062, 1082 and 1102 are charged. Charging of each storage battery is controlled by an individual charge control unit that controls charging of the storage battery. Thereby, the time zone when the storage batteries 1062, 1082 and 1102 are charged is dispersed. Therefore, as shown in FIG. 7, the storage battery 1082 is not charged in the time zone from 1 o'clock to 2 o'clock when the storage battery 1102 is charged.
　蓄電池１０６２，１０８２および１１０２の各々が充電される時間帯は、充電制御部１１２４により調整され、図７に示されるように、需要家１２４２，１２４４または１２４６が電力を消費していない時間帯から選択される。需要家１２４２，１２４４または１２４６が電力を消費している時間帯においては、蓄電池１０６２，１０８２および１１０２の充電が禁止される。 The time zone during which each of the storage batteries 1062, 1082 and 1102 is charged is adjusted by the charging control unit 1124, and as shown in FIG. 7, the customer 1242, 1244 or 1246 is selected from the time zone when the power is not consumed. Is done. In the time zone in which the consumers 1242, 1244 or 1246 are consuming electric power, charging of the storage batteries 1062, 1082 and 1102 is prohibited.
　需要家１２４２，１２４４または１２４６が電力を消費している時間帯を考慮して蓄電池１０６２，１０８２および１１０２が充電される時間帯を制御することにより、図８に示されるように、電気事業者から供給される供給電力が、低く設定された供給電力の上限より少なくなる。これにより、発電設備、送配電設備等を縮小でき、電力料金が総合的に抑制される。 By controlling the time period in which the storage batteries 1062, 1082 and 1102 are charged in consideration of the time period in which the consumer 1242, 1244 or 1246 is consuming power, as shown in FIG. The supplied power to be supplied is less than the lower limit of the supplied power. Thereby, a power generation facility, a power transmission / distribution facility, etc. can be reduced, and a power charge is comprehensively suppressed.
　６　蓄電池の充電の制御の流れ
　図９は、蓄電池の充電の制御の流れを示すフローチャートである。 6 Flow of Control of Charging of Storage Battery FIG. 9 is a flowchart showing the flow of control of charging of the storage battery.
　図９に示されるステップＳ１０１において充電されなければならない蓄電池、すなわち充電の対象に追加されることが予定された充電予定の蓄電池が発生した場合は、ステップＳ１０２からＳ１０６までにおいて充電予定の蓄電池の充電を直ちに開始できるか否かが調べられる。また、充電予定の蓄電池の充電を直ちに開始できる場合は、ステップＳ１０７において充電予定の蓄電池の充電が直ちに開始され、充電予定の蓄電池の充電を直ちに開始できない場合は、ステップＳ１０８からＳ１１３までにおいて充電予定の蓄電池の充電が予約される。 When a storage battery that must be charged in step S101 shown in FIG. 9, that is, a storage battery that is scheduled to be added to the charging target, is generated, the storage battery that is scheduled to be charged is charged in steps S102 to S106. To see if it can start immediately. If charging of the storage battery scheduled to be charged can be started immediately, charging of the storage battery scheduled to be charged is started immediately in step S107. If charging of the storage battery scheduled to be charged cannot be started immediately, charging is scheduled in steps S108 to S113. Rechargeable battery is reserved.
　ステップＳ１０１に続くステップＳ１０２においては、充電予定の蓄電池の充電のために消費されている消費電力Ａが蓄電池監視部１２０４により取得される。 In step S102 following step S101, the power consumption A consumed for charging the storage battery to be charged is acquired by the storage battery monitoring unit 1204.
　ステップＳ１０２に続くステップＳ１０３においては、蓄電池１０６２，１０８２および１１０２のうちの充電予定の蓄電池以外の蓄電池の充電のために消費されている現在の消費電力Ｂが蓄電池監視部１２０４により取得される。 In step S103 following step S102, the storage battery monitoring unit 1204 acquires the current power consumption B consumed for charging a storage battery other than the storage battery to be charged among the storage batteries 1062, 1082 and 1102.
　ステップＳ１０３に続くステップＳ１０４においては、需要家１２４２，１２４４および１２４６の現在の消費電力Ｃが供給先監視部１２０２により取得される。 In step S104 following step S103, the current power consumption C of the consumers 1242, 1244 and 1246 is acquired by the supply destination monitoring unit 1202.
　ステップＳ１０４に続くステップＳ１０５においては、現在の消費電力の合計Ａ＋Ｂ＋Ｃが算出される。 In step S105 following step S104, the current power consumption total A + B + C is calculated.
　ステップＳ１０５に続くステップＳ１０６においては、算出された現在の消費電力の合計Ａ＋Ｂ＋Ｃと電気事業者から供給される供給電力の上限とが充電予定の蓄電池の充電を制御する個別充電制御部により比較され、合計Ａ＋Ｂ＋Ｃが上限を超過しない場合は、処理がステップＳ１０７に進められ、合計Ａ＋Ｂ＋Ｃが上限を超過する場合は、処理がステップＳ１０８に進められる。 In step S106 following step S105, the calculated total current consumption A + B + C and the upper limit of the supply power supplied from the electric power company are compared by the individual charge control unit that controls the charging of the storage battery to be charged, If the total A + B + C does not exceed the upper limit, the process proceeds to step S107. If the total A + B + C exceeds the upper limit, the process proceeds to step S108.
　ステップＳ１０７においては、充電予定の蓄電池の充電が充電予定の蓄電池の充電を制御する個別充電制御部により開始される。これにより、充電予定の蓄電池の充電が直ちに開始されても需要家１２４２，１２４４および１２４６の消費電力と蓄電池１０６２，１０８２および１１０２の充電のために消費される消費電力との合計が上限を超過しない場合は、充電予定の蓄電池の充電が直ちに開始される。 In step S107, charging of the storage battery scheduled to be charged is started by an individual charge control unit that controls charging of the storage battery scheduled to be charged. Thereby, even if charging of the storage battery scheduled to be charged is started immediately, the total of the power consumption of the consumers 1242, 1244 and 1246 and the power consumption consumed for charging the storage batteries 1062, 1082 and 1102 does not exceed the upper limit. In this case, charging of the storage battery scheduled to be charged is started immediately.
　ステップＳ１０８においては、予定時間帯において蓄電池１０６２，１０８２および１１０２のうちの充電予定の蓄電池以外の蓄電池の充電のために消費される消費電力である予定消費電力Ｄが蓄電池監視部１２２４により取得される。 In step S108, the storage battery monitoring unit 1224 acquires the scheduled power consumption D, which is the power consumed for charging a storage battery other than the storage battery scheduled to be charged among the storage batteries 1062, 1082 and 1102 in the scheduled time zone. .
　ステップＳ１０８に続くステップＳ１０９においては、予定時間帯における需要家１２４２，１２４４および１２４６の蓄電池による電力消費分を削除した消費電力の合計である予定消費電力Ｅが供給先監視部１２２２により取得される。 In step S109 following step S108, the supply destination monitoring unit 1222 acquires the planned power consumption E, which is the sum of the power consumption obtained by deleting the power consumption by the storage batteries of the consumers 1242, 1244 and 1246 in the scheduled time period.
　ステップＳ１０９に続くステップＳ１１０においては、予定消費電力の合計Ａ＋Ｄ＋Ｅが算出される。 In step S110 following step S109, the total planned power consumption A + D + E is calculated.
　ステップＳ１１０に続くステップＳ１１１においては、算出された予定消費電力の合計Ａ＋Ｄ＋Ｅと電気事業者から供給される供給電力の上限とが充電予定の蓄電池の充電を制御する個別充電制御部により比較され、合計Ａ＋Ｄ＋Ｅが上限を超過しない場合は、処理がステップＳ１１２に進められ、合計Ａ＋Ｄ＋Ｅが上限を超過する場合は、処理がステップＳ１１３に進められる。 In step S111 following step S110, the calculated total power consumption A + D + E and the upper limit of the supplied power supplied from the electric power company are compared by the individual charge control unit that controls the charging of the storage battery scheduled to be charged. If A + D + E does not exceed the upper limit, the process proceeds to step S112. If the total A + D + E exceeds the upper limit, the process proceeds to step S113.
　ステップＳ１１２においては、予定消費電力Ｄおよび予定消費電力Ｅの取得に使用された予定時間帯が充電予定の蓄電池が充電される時間帯に設定される。 In step S112, the scheduled time zone used to acquire the planned power consumption D and the planned power consumption E is set to the time zone during which the storage battery scheduled to be charged is charged.
　ステップＳ１１３においては、予定時間帯が変更され、処理が再びステップＳ１０８に進められる。これにより、合計Ａ＋Ｄ＋Ｅが上限を超過しない時間帯が発見されるまでステップＳ１０８からＳ１１１までが繰り返し実行される。 In step S113, the scheduled time zone is changed, and the process proceeds again to step S108. Thus, steps S108 to S111 are repeatedly executed until a time period in which the total A + D + E does not exceed the upper limit is found.
　この蓄電池の充電の制御によれば、需要家１２４２，１２４４および１２４６の消費電力と蓄電池１０６２，１０８２および１１０２の充電のために消費される電力との合計が上限より少なくなるように商用電源１２６２による蓄電池１０６２，１０８２および１１０２の充電が制御される。 According to the control of the charging of the storage battery, the commercial power supply 1262 is used so that the sum of the power consumed by the consumers 1242, 1244 and 1246 and the power consumed for charging the storage batteries 1062, 1082 and 1102 is less than the upper limit. Charging of storage batteries 1062, 1082 and 1102 is controlled.
　７　電力の供給先の変形例
　図１０に示されるように、ひとつの需要家１２４２からなる供給先が需要家集団１２８２からなる供給先に置き換えられてもよく、ひとつの需要家１２４４からなる供給先が需要家集団１２８４からなる供給先に置き換えられてもよく、ひとつの需要家１２４６からなる供給先が需要家集団１２８６からなる供給先に置き換えられてもよい。これにより、需要家集団がひとつの需要家設備に対応し、需要家設備群に備えられる需要家設備の数が減少する。このことは、電気事業者設備１０２４にかかる制御負荷を抑制し放電制御部１１２２および充電制御部１１２４が処理しなければならないデータの量を減らすことに寄与する。したがって、電力需給を調整するシステム１０００に要求される処理能力が低下する。ひとつの需要家からなる供給先と需要家集団からなる供給先とが混在してもよい。 7. Modification of Power Supply Destination As shown in FIG. 10, a supply destination consisting of one consumer 1242 may be replaced with a supply destination consisting of a consumer group 1282, and a supply destination consisting of one consumer 1244. May be replaced with a supply destination consisting of a consumer group 1284, or a supply destination consisting of one consumer 1246 may be replaced with a supply destination consisting of a consumer group 1286. Thereby, a consumer group respond | corresponds to one consumer equipment, and the number of the consumer equipments with which a consumer equipment group is equipped decreases. This contributes to reducing the amount of data that the discharge control unit 1122 and the charge control unit 1124 must process by suppressing the control load on the electric utility facility 1024. Therefore, the processing capacity required for the system 1000 that adjusts the power supply and demand decreases. A supply destination consisting of one consumer and a supply destination consisting of a consumer group may be mixed.
　需要家集団１２８２，１２８４および１２８６の各々である各需要家集団は、同一のコミュニティーに属する。例えば、各需要家集団は、ひとつの区画または地域に属する需要家集団であってもよいし、電気事業者との電力供給の契約形態が同一である需要家集団であってもよいし、事業の職種が同一である需要家集団であってもよい。 Each customer group which is each of the customer groups 1282, 1284 and 1286 belongs to the same community. For example, each consumer group may be a consumer group that belongs to one section or region, may be a consumer group that has the same contract form of power supply with an electric power company, or a business Customer groups with the same occupation may be used.
　８　実施の形態の利点

Is done. In addition, the time periods during which the storage batteries 1062, 1082 and 1102 are charged are dispersed, and the occurrence of a new demand peak for electric power due to the charging of the storage batteries 1062, 1082 and 1102 is suppressed.
