Description

【０００１】
【発明の属する技術分野】
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。
【０００２】
【従来の技術】
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。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。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。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。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。
【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。
【０００４】
【発明が解決しようとする課題】
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。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。
【０００５】
本発明の目的は、コミュニティー内における電力損失を最小にすることによって、エネルギーを有効に利用でき、さらに安定した系統電圧を維持できるシステムを提供することにある。
【０００６】
【課題を解決するための手段】
本発明の分散型エネルギーコミュニティーシステムは、各々が発電装置とエネルギー蓄積装置を有し、電力需要の日負荷特性が異なる複数の分散電源システムが相互に接続された分散型エネルギーコミュニティーシステムにおいて、各分散電源システムについて、当該分散電源システムへの送電損失が当該分散電源システムのエネルギー蓄積装置の充放電損失よりも小さくなるエリアを予め求め、各分散電源システムから、発電装置の発電量を示すデータと、エネルギー蓄積装置のエネルギー貯蔵量を示すデータと、負荷の電力消費量を示すデータを受信し、これらをもとに、各分散電源システムが前記エリア内の送電損失が小さい分散電源システムから優先的に電力の供給を受けるようにしながら、前記複数の分散電源システムの間で電力を融通し合うために必要な発電量および受送電量の予定値を分散電源システムごとに計算し、該予定値を当該分散電源システムに送信するセンタを有することを特徴とする。
【０００７】
また、本発明の分散型エネルギーコミュニティーシステムは、各々が発電装置とエネルギー蓄積装置を有し、電力需要の日負荷特性が異なる複数の分散電源システムが相互に接続された分散型エネルギーコミュニティーシステムにおいて、各分散電源システムの発電量と、エネルギー貯蔵量と、負荷の電力消費量を含むデータから得られた、前記複数の分散電源システムの間で電力を融通し合うために必要な発電量および受送電量の予定値に基づいて、複数の分散電源システム間で電力を融通する制御と、該制御にもかかわらず、発電量が不足しエネルギー貯蔵量にも余裕がない分散電源システムが存在し、発電量が不足しておらずエネルギー貯蔵量にも余裕がある分散電源システムから、前記発電量が不足しエネルギー貯蔵量にも余裕がない分散電源システムへ送電する場合に、送電損失が小さい分散電源システムから優先的に発電量および送電量を増加させ、送電する制御とを行なうセンタを有することを特徴とする。
【０００８】
前記センタは、発電装置とエネルギー蓄積装置を備え、前記センタからも前記複数の分散電源システムに電力を融通するようにしてもよい。
【００１４】
【発明の実施の形態】
図１に本発明の分散型エネルギーコミュニティーシステムの一実施形態の概略構成を示す。図１に示すように、コミュニティー内には一戸建住宅１、集合住宅２、オフィス３、学校４等様々な特性の電力負荷を有する複数の分散電源システムが存在する。本実施形態の分散電源システムは、一戸建住宅１に例示したように、発電装置として燃料電池５を、エネルギー蓄積装置としてバッテリー６を用いていて、負荷７に給電する。また、各分散電源システムは制御装置８を有しており、送電するための電力線９およびデータ通信するための通信線１０によりセンタ１１と接続される。センタ１１における制御監視装置１２はデータベース（不図示）を備え、各分散電源システムのデータを収集してデータベースに蓄積し、このデータベースを基に各分散電源システムの運用管理を、通信線１０を利用して行う。また、センタ１１において商用電源１３と連系されており、コミュニティー内での分散電源システムだけでは必要な電力を供給できない場合においては、必要に応じて商用電源１３より買電する。また、センタ１１に燃料電池１４とバッテリー１５を備えて、ここから各分散電源システムへ電力を供給することとしてもよい。
【００１５】
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。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。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。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。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。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。
【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。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。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。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。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。
【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。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）。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）。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）。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）。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）。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。
【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。
【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。
【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）。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。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）。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）。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。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）。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）。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）。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。
【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。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。
【００２２】
【発明の効果】
以上説明したように本発明によれば、分散型エネルギーコミュニティーにおいて、電力需要の日負荷特性が異なる分散電源システム間においての電力補完が制御されるため、エネルギー蓄積装置の容量を大きくすることなく発電装置の稼動率の高いシステムとすることができる。
【００２３】
また、充放電損失および送電損失を最小にできる状態で運用制御することにより、コミュニティー内のエネルギーを有効に利用することができる。
【００２４】
さらに、発電電力および受送電電力の予定値を算出しておくことにより、エネルギー有効利用の効果を十分に発揮することができる。
【００２５】
また、受送電電力の予定値に応じて系統電圧を制御することにより、コミュニティー内の系統電圧の変動を比較的簡単に抑制できるという効果もある。

BACKGROUND OF THE INVENTION
The present invention relates to an energy community system having a plurality of distributed power supply systems, and more particularly to a distributed energy community system that is a power system to which a plurality of distributed power supply systems having a power generation device and an energy storage device are connected, and a control method thereof.
[0002]
[Prior art]
In order to increase the operating rate of the power generation device in the distributed power supply system and to reduce the capacity of the energy storage device, it is necessary to perform reverse power flow to the power system. Therefore, an energy system that transfers power between distributed power supply systems within a community is effective for increasing the operating rate of the power generation apparatus. In this case, when a battery is used as the energy storage device, surplus power is charged in the battery, but is transmitted to the system before being overcharged. Insufficient power is compensated by discharge from the battery, but power is received from the system before overdischarge occurs. That is, when surplus power is generated in the community system, the amount of discharge is suppressed, and when insufficient power is generated, power is purchased from the commercial system.
[0003]
However, if each distributed power supply system performs power transmission / reception to / from the power system unplanned in this way, surplus power or insufficient power may temporarily occur even in the entire community, and the voltage of the power system fluctuates greatly.
[0004]
[Problems to be solved by the invention]
In the conventional energy system described above, there is not much merit in power exchange between distributed power supply systems having similar power demand load characteristics because the ratio of power interchange within the community is reduced. Therefore, it is necessary to include distributed power supply systems with different daily load characteristics of power demand in the community. In this case, however, the community will be large to some extent, so operation that takes into account losses due to power transmission, voltage drops in the system voltage, etc. There is a problem that planning is necessary.
[0005]
An object of the present invention is to provide a system capable of effectively using energy and maintaining a stable system voltage by minimizing power loss in a community.
[0006]
[Means for Solving the Problems]
Distributed energy community system of the present invention, each have a power generator and an energy storage device, in a distributed energy community system daily load characteristics of the power demand different distributed power system is interconnected, each distributed About the power supply system, an area in which the transmission loss to the distributed power supply system is smaller than the charge / discharge loss of the energy storage device of the distributed power supply system is obtained in advance, and from each distributed power supply system, data indicating the power generation amount of the power generator, and data indicating the energy storage amount of the energy storage device receives data indicating the power consumption of the load, based on these, preferentially each distributed power system from the distributed power system transmission loss is small in the area Power is supplied between the plurality of distributed power systems while receiving power supply. The predetermined value of the power generation amount and receiving and supplying electricity amount necessary for mutual flexibility calculated for each distributed power supply system, and having a center to send該予value to the distributed power supply system.
[0007]
Further, the distributed energy community system of the present invention is a distributed energy community system in which a plurality of distributed power supply systems each having a power generation device and an energy storage device and having different daily load characteristics of power demand are connected to each other. The amount of power generated and received / transmitted to exchange power among the plurality of distributed power systems obtained from data including the amount of power generated by each distributed power system, the amount of energy stored, and the power consumption of the load. based on the expected values of the amount, the control for interchange power between the plurality of distributed power system, despite the control, the power generation amount is insufficient is present distributed power systems can not afford to energy storage, power from the amount you can afford to energy storage not missing distributed power supply system, it can afford to energy storage the power generation amount is insufficient When power to the distributed power system, transmission losses increase preferentially generation amount and the amount of transmitted power from a small distributed power system, characterized by having a center that performs the control of power transmission.
[0008]
The center may include a power generation device and an energy storage device, and power may be exchanged from the center to the plurality of distributed power supply systems.
[0014]
DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 shows a schematic configuration of an embodiment of a distributed energy community system of the present invention. As shown in FIG. 1, there are a plurality of distributed power supply systems having power loads with various characteristics such as a detached house 1, an apartment house 2, an office 3, and a school 4 in a community. As illustrated in the detached house 1, the distributed power supply system of the present embodiment uses the fuel cell 5 as the power generation device and the battery 6 as the energy storage device, and supplies power to the load 7. Each distributed power supply system has a control device 8 and is connected to the center 11 by a power line 9 for power transmission and a communication line 10 for data communication. The control monitoring device 12 in the center 11 includes a database (not shown), collects data of each distributed power supply system and accumulates it in the database, and uses the communication line 10 for operation management of each distributed power supply system based on this database. And do it. Further, when the center 11 is connected to the commercial power supply 13 and necessary power cannot be supplied only by the distributed power supply system in the community, the commercial power supply 13 is purchased as necessary. Alternatively, the center 11 may be provided with a fuel cell 14 and a battery 15 to supply power to each distributed power system.
[0015]
FIG. 2 shows an example of daily load characteristics of power demand and power complementation in the distributed energy community system of FIG. In FIG. 2, a curve 20 indicates load values of the office 3 and the school 4, and a curve 21 indicates load 13 values of the houses 1 and 2. If a distributed power supply system with loads with different power demand characteristics exists in the community, the generated power can be used effectively by sharing power, and power can be generated without installing a large capacity battery. The operating rate of the apparatus can be increased. As indicated by arrows in FIG. 2, in the morning and evening, power is supplied to the house from a building with few people such as the office 3 and the school 4. In the daytime, surplus electricity in the house is supplied to offices and schools. Here, the simplest example is shown, but there are many distributed power supply systems as described above in the community, and a plan that considers charge / discharge loss, power transmission loss, and the like is necessary.
[0016]
A method for calculating the planned values of generated power and received / transmitted power will be described. First, a predicted value of power consumption of each distributed power supply system is calculated from past data, weather information, day of the week, schedule of events, and the like. In other words, past data with similar situations is searched, and correction is performed as necessary. For each distributed power supply system, an area in which the power transmission loss is smaller than the charge / discharge loss of the battery is calculated in advance. For simplicity, a group based on branching of power lines or the like may be used as the area.
[0017]
FIG. 3 shows a planned value calculation flow of generated power and received / transmitted power in this embodiment. In this calculation method, assuming that the power generation amount of the first distributed power supply system is insufficient in a certain time zone (step S1), there is a margin based on the relationship between the power generation amount and the predicted power consumption value in the previously calculated area. A certain distributed power supply system is searched in ascending order of transmission loss (step S2). When the supplement in this area is insufficient (step S3), the discharge amount is calculated in consideration of the time period in which the battery discharge capacity and the predicted power consumption are below the power generation amount (step S4). If this does not solve the shortage (step S5), a distributed power supply system having a margin for power generation is searched outside the area in ascending order of power transmission loss (step S6). If the electric power is insufficient (step S7), the electric power is integrated as electric power to be purchased from commercial power (step S8). This procedure is similarly performed for each distributed power supply system (step S9), and when it is necessary to purchase power, a planned power purchase value for that time zone is calculated (step S10). As described above, the same processing is performed in each time zone, and the calculated generated power and received / transmitted power are transmitted as command values to each distributed power supply system.
[0018]
During actual operation, there is no demand for electricity as planned, and some fluctuations are expected, and there may be a significant deviation from the planned value due to changes in weather conditions or failure of the power generator.
[0019]
FIG. 4 shows a control flow for adjusting the power generation amount in the community.
[0020]
In this method of adjusting the power generation amount, first, a distributed power supply system that lacks power is searched (step S11). Here, the shortage indicates a case where there is no room in the amount of electricity stored in the battery despite full power generation. When the target distributed power supply system is found (step S12), the distributed power supply system having a margin in the power generation amount is searched in the order closest to the distributed power supply system (step S13). When a distributed power supply system with a margin is found, a command is issued to increase the power generation amount by a necessary amount (step S15). If the power is still insufficient after full power generation, the search is continued. If the power shortage cannot be compensated for in the community, it is necessary to increase the amount of power purchased from the commercial power source (step S17). If there is no distributed power supply system with insufficient power, a search is made for a distributed power supply system in which power is surplus, that is, the battery is likely to be fully charged (step S18). When a target power supply is found (step S19), if power is being purchased from a commercial power supply (step S20), the power purchase amount is suppressed (step S21), and if not being purchased, the power generation amount of the distributed power supply system is suppressed (step S21). Step S22). In the case of an urgent and large power shortage due to a failure or the like, it is necessary to quickly compensate for the power shortage of the partial system in the community by using battery discharge or the like together.
[0021]
As described above, if the predicted value is calculated in advance, it is possible to control the operation of the energy management in the community in a state that is always close to optimum in terms of minimizing power loss. In addition, because the received and transmitted power to the system is predicted and managed, for example, by remotely controlling the tap switching of the transformer 16 in each distributed power system shown in FIG. It is also possible to maintain it stably.
[0022]
【The invention's effect】
As described above, according to the present invention, in a distributed energy community, power supplementation is controlled between distributed power supply systems having different daily load characteristics of power demand, so that it is possible to generate power without increasing the capacity of an energy storage device. It can be set as the system with the high operation rate of an apparatus.
[0023]
Further, by controlling the operation in a state where charging / discharging loss and power transmission loss can be minimized, the energy in the community can be used effectively.
[0024]
Furthermore, by calculating the planned values of generated power and received / transmitted power, the effect of effective energy use can be sufficiently exhibited.
[0025]
Further, by controlling the system voltage according to the scheduled value of the received / transmitted power, there is an effect that the fluctuation of the system voltage in the community can be suppressed relatively easily.
