【発明の属する技術分野】 BACKGROUND OF THE INVENTION
本発明は、複数の分散電源システムを有するエネルギーコミュニティーシステムに関し、特に、発電装置とエネルギー蓄積装置を有する複数の分散電源システムが接続された電力系統である分散型エネルギーコミュニティーシステムおよびその制御方法に関する。 The present invention relates to an energy community system having a plurality of distributed power systems, in particular, it relates to distributed energy community system and a control method thereof plurality of distributed power supply system is connected to an electric power system having a power generator and an energy storage device.

【従来の技術】 BACKGROUND OF THE INVENTION
分散電源システムにおいて発電装置の稼動率を上げるためには、またエネルギー蓄積装置の容量を小さくするためには、電力系統への逆潮流を行う必要がある。 To increase the operating rate of the generator in a distributed power supply system, and to reduce the capacity of the energy storage device, it is necessary to reverse power flow to the power grid. したがって、分散電源システム間の電力授受をコミュニティー内において行うエネルギーシステムは、発電装置の稼動率を上げるために効果的である。 Therefore, the energy system for the transfer of power between the distributed power supply system in the community, is effective for increasing the operating rate of the generator. この場合、エネルギー蓄積装置としてバッテリーを用いる場合、余剰電力はバッテリーに充電されるが過充電になる前に系統に送電させることになる。 In this case, when using a battery as an energy storage device, excess power will be transmitting to the system before it is charged to the battery to become overcharged. また、不足電力はバッテリーからの放電により補うが、過放電になる前に系統から受電することになる。 Although insufficient power compensated by the discharge from the battery, will be powered from the system before the over-discharge. すなわち、コミュニティー系統内で余剰電力が生じた場合には放電量を抑制し、不足電力が生じた場合は商用系統から買電することになる。 That is, when the surplus electric power within the community system occurs suppresses discharge amount, if the power shortage has occurred will purchase electricity from the grid.
【0003】 [0003]
ところが、このように各分散電源システムが無計画に電力系統に対する受送電を行うとコミュニティー全体でも一時的に余剰電力あるいは不足電力が生じてしまう場合があり、電力系統の電圧が大きく変動する。 However, this way may each distributed power system will be haphazardly Doing receiving and supplying electric even entire community temporarily cause excess power or insufficient power to the power system, the voltage of the power system greatly fluctuates.

【発明が解決しようとする課題】 [Problems that the Invention is to Solve
上述した従来のエネルギーシステムは、同じような電力需要の負荷特性を有する分散電源システム間での電力授受では、コミュニティー内で電力を融通し合う割合が少なくなるためメリットがあまり出ない。 Conventional energy system described above, in the power exchange between distributed power supply system having load characteristics of similar power demand, does not appear very advantageous since the proportion of mutual interchange power decreases in the community. したがって、電力需要の日負荷特性が異なる分散電源システムをコミュニティー内に包括する必要があるが、この場合ある程度大規模なコミュニティーとなるため、送電等による損失や系統電圧の電圧降下等を考慮した運用計画が必要となるという問題がある。 Therefore, it is necessary to embrace distributed power supply system load characteristics different days of the power demand in the community, in this case for a somewhat large community, considering the voltage drop or the like of the loss and the system voltage by the power transmission or the like operation plan there is a problem that is required.

図2に、図1の分散型エネルギーコミュニティーシステムにおける電力需要の日負荷特性と電力補完の例を示す。 Figure 2 shows an example of the daily load characteristics and the power supplement power demand in distributed energy community system of FIG. 図2において、曲線20はオフィス3および学校4等の負荷の値を示し、曲線21は住宅1および2の負荷13の値を示している。 2, curve 20 represents the value of the load, such as an office 3 and schools 4, curve 21 represents the value of the house 1 and 2 of the load 13. このように電力需要の特性が異なる負荷を持つ分散電源システムがコミュニティー内に存在すると、電力を融通し合うことにより、発電電力を有効に利用でき、大きな容量のバッテリー等を設置しなくても発電装置の稼動率を上げることができる。 When distributed power system having such a load characteristic of the power demand is different is present in the community, by mutual interchange power, generated power can be effectively used, without installing a battery or the like of a large capacity generator it is possible to increase the operating rate of the apparatus. 図2で矢印で示すように、朝夕においては、オフィス3および学校4等の人があまりいないビルから、住宅へ電力を供給する。 As shown by the arrows in Figure 2, in the morning and evening, from building human, such as an office 3 and school 4 are not many, and supplies power to the house. 昼間には、住宅で余った電力をオフィスおよび学校等へ供給する。 Daytime supplies the electric power surplus in a residential to offices and schools. ここでは、最も単純な例を示しているが、コミュニティー内には上記のような分散電源システムが多数散在しており、充放電損失や送電損失等を考慮した計画が必要となってくる。 Here, although the simplest example, the in the community are scattered many distributed power systems as described above, plans in consideration of the charging and discharging loss and transmission loss and the like is necessary.
【0016】 [0016]
発電電力および受送電電力の予定値の算出法について説明する。 The calculation method of the expected value of the generated power and the receiving and supplying electric power will be described. まず、各分散電源システムの消費電力の予測値を過去のデータ、気象情報、および曜日や行事予定等から算出する。 First, to calculate the predicted value of the power consumption of each distributed power system from the historical data, weather information, and day and events schedule like. すなわち、状況の類似した過去のデータを検索し、必要に応じて補正をかける。 That is, it searches the historical data similar situation applies a correction if necessary. また各分散電源システムについて、バッテリーの充放電損失よりも送電損失が小さくなるエリアを予め計算しておく。 Also for each distributed power system calculated in advance an area where the transmission loss is smaller than the charge and discharge loss of the battery. 簡単にするためには、電力線の枝分かれ等によるグループをそのエリアとしても良い。 For simplicity, a group by branching or the like of the power line may be the area.
【0017】 [0017]
図3に、本実施形態における発電電力および受送電電力の予定値算出フローを示す。 3 shows a predetermined value calculation flow of generated power and receiving and supplying electric power in the present embodiment. この算出方法は、ある時間帯において第一の分散電源システムの発電量が不足しているとすると(ステップS1)、前述の予め計算したエリア内において発電量と消費電力予測値の関係から余裕のある分散電源システムを送電損失の小さい順に検索する(ステップS2)。 The calculation method is the amount of power generated by the first distributed power system to be insufficient in the time zone (step S1), the margin from the relationship between the power estimation value and the power generation amount in the area which was previously calculated previously described Search for certain distributed power system in ascending order of transmission losses (step S2). このエリア内での補完で足りない場合には(ステップS3)、バッテリーの放電容量および消費電力予測値が発電量を下回る時間帯までを考慮して放電量を算出する(ステップS4)。 If not enough complemented in this area (step S3), and the discharge capacity and power estimation value of the battery to calculate a discharge amount in consideration of the up time zone below the power generation amount (step S4). これでも不足が解消されない場合には(ステップS5)、そのエリア外に送電損失が小さい順に発電に余裕のある分散電源システムを検索していく(ステップS6)。 If insufficient even this persists (step S5), and continue to search for distributed power system having a margin for power generation in order of small transmission losses outside the area (step S6). なおも電力が不足している場合には(ステップS7)、その電力を商用から買電する電力として積算していく(ステップS8)。 Still in the case where power is insufficient (step S7), and by accumulating the power as electric power electricity purchase from a commercial (step S8). この手順を各分散電源システムについて同様に行っていき(ステップS9)、買電する必要がある場合にはその時間帯の買電予定値を算出する(ステップS10)。 Will conduct this procedure in the same manner for each distributed power supply system (step S9), and if there is a need to power purchase calculating a power purchase predetermined value of the time period (step S10). 以上のように各時間帯において同様に行っていき、算出された発電電力および受送電電力を各分散電源システムに指令値として送信する。 It will carried out in the same manner at each time period as described above, and transmits the generated power and receiving and supplying electric power is calculated as a command value to each distributed power system.
【0018】 [0018]
実際の運用時においては、予定値の通りに電力需要があるものではなく、ある程度の変動は予想され、また気象状態の変化や発電装置の故障等の原因で予定値から大きくずれる場合もある。 During actual operation, not that there is power demand as the predetermined value, it is expected some variation, also sometimes deviate significantly from the expected value in the cause of failure of a change in weather conditions and power generator.
【0019】 [0019]
図4に、コミュニティー内の発電量を調整する制御フローを示す。 4 shows a control flow for adjusting the power generation amount in the community.
【0020】 [0020]
この発電量の調整方法は、まず、電力が不足する分散電源システムを検索する(ステップS11)。 Method of adjusting the amount of power generation, first, searches the distributed power supply system power is insufficient (step S11). ここで、不足するというのは、フル発電しているにもかかわらず、バッテリーの蓄電量に余裕がなくなってきた場合を示す。 Here, because insufficient, despite the full-power generation, shows the case that has been lost is room in the storage amount of the battery. 対象とする分散電源システムが見つかると(ステップS12)、その分散電源システムに近い順に発電量に余裕がある分散電源システムを検索していく(ステップS13)。 If it finds distributed power system of interest (step S12), the continue to search for distributed power systems where there is a margin in the power generation amount in the order of closeness to the distributed power supply system (step S13). 余裕のある分散電源システムが見つかると、発電量を必要な分だけ増加するように指令を出す(ステップS15)。 If it finds distributed power systems can afford, it issues a command to increase by the amount required power generation amount (step S15). フル発電してもまだ電力が不足している場合には、さらに検索を継続して行う。 If you still power even when full power is insufficient, carried out continued for a further search. コミュニティー内で電力不足が補えない場合には、商用電源からの買電量を増加させる必要がある(ステップS17)。 If no compensated power shortage in the community, it is necessary to increase the power purchase amount from the commercial power supply (step S17). 電力が不足する分散電源システムが存在しない場合には、電力が余るすなわちバッテリーが満充電になりそうな分散電源システムを検索する(ステップS18)。 If there is no distributed power supply system is insufficient power, the power is left over ie battery Search likely distributed power system becomes fully charged (step S18). 対象とする電源が見つかると(ステップS19)、商用電源から買電中ならば(ステップS20)買電量を抑制し(ステップS21)、買電中でなければ分散電源システムの発電量を抑制する(ステップS22)。 When it finds a source of interest (step S19), if the power purchase in the commercial power supply (step S20) power purchase amount is suppressed (step S21), and suppresses the generation of the distributed power system if not in purchased power ( step S22). なお、故障等のために緊急で大きな電力不足が生じた場合には、バッテリーの放電等も併用してコミュニティー内における部分系統の電力不足を迅速に補う必要はある。 Incidentally, if a large electric power shortage urgent because of the failure or the like occurs is quickly required to compensate for the power shortage of the subsystem in the community in combination also and discharge of the battery.
【0021】 [0021]
以上のように、予め予測値が算出されていれば、コミュニティー内のエネルギー管理を電力損失の最小化という点から常に最適に近い状態で運用制御することができる。 As described above, in advance if the predicted value is only to be calculated, it is possible to operate the control at all times near optimal conditions in terms of minimizing the power loss of energy management within the community. また、系統に対する受送電電力を予測し管理しているため、例えば、図1に示された各分散電源システム内の変圧器16のタップ切り替えを遠隔で制御することにより、コミュニティー系統内の電圧を安定に維持することも可能となる。 Further, since the management predicts the receiving and supplying electric power to the grid, for example, by controlling the tap-changing transformer 16 in each distributed power system shown in Figure 1 remotely, the voltage in the community system it is possible to stably maintain.
