Description

電力制御装置、電力制御装置の制御方法及びプログラムPower control apparatus, control method and program for power control apparatus
　本発明は、電力制御装置、電力制御装置の制御方法及びプログラムに関する。 The present invention relates to a power control apparatus, a control method for the power control apparatus, and a program.
　近年、太陽光発電機や風力発電機のような分散型発電機が普及している。 In recent years, distributed generators such as solar power generators and wind power generators have become widespread.
　これらの分散型発電機は、電力需要とは関係なく気象条件などによって発電量が増減するため、余剰電力が生じた場合には電力系統への逆潮流が生じ、電力系統の電圧や周波数に影響を与えるおそれがある。 These distributed generators increase or decrease the amount of power generation depending on weather conditions, etc. regardless of power demand, so when surplus power is generated, reverse power flow to the power system occurs, affecting the voltage and frequency of the power system. There is a risk of giving.
　そのため、電力系統上の各所に電圧調整装置を設置して電力系統を安定化させる技術や、分散型発電機により生じた余剰電力のエネルギーをバッテリや電気温水器等の各種電力負荷装置に蓄えるようにすることにより電力系統を安定化させる技術等が開発されている（例えば特許文献１を参照）。 For this reason, voltage regulators are installed in various places on the power system to stabilize the power system, and excess power generated by the distributed generator is stored in various power load devices such as batteries and electric water heaters. In order to stabilize the electric power system, etc. have been developed (see, for example, Patent Document 1).

And the maintenance cost of this control system will be large.
　例えば、分散型発電機やバッテリ等の新設や撤去等が行われる都度、電力系統上の各所に設けられている分散型発電機等と中央の制御装置との間を結ぶデータ通信網の再構築や、制御装置に設定されている各種の設定データやプログラムの変更等を行うことが必要になる。 For example, whenever a new installation or removal of a distributed generator or battery, etc. is performed, the data communication network that connects the distributed generator installed at various locations on the power system and the central control unit is rebuilt. It is also necessary to change various setting data and programs set in the control device.

　このような観点から、電力系統の全体を統括して制御するような装置を用いることなく、電力系統の全体を最適に制御可能とする技術が求められている。 From such a point of view, there is a need for a technology that can optimally control the entire power system without using a device that controls the entire power system.

　本明細書および添付図面の記載により、少なくとも以下の事項が明らかとなる。以下、本発明をその一実施形態に即して添付図面を参照しつつ説明する。 At least the following matters will become clear from the description of this specification and the accompanying drawings. Hereinafter, the present invention will be described in accordance with an embodiment thereof with reference to the accompanying drawings.
　本発明の実施形態に係る電力システム１０００を図１に示す。電力システム１０００は、商用の電力系統を構成する配電線１０１０に、変圧器１０３０を介して連系する複数のエージェント２００を有して構成されている。 FIG. 1 shows a power system 1000 according to an embodiment of the present invention. The power system 1000 includes a plurality of agents 200 that are interconnected via a transformer 1030 to a distribution line 1010 that constitutes a commercial power system.
　エージェント２００は、発電装置３００、電力負荷装置４００及び制御装置１００を有して構成される。またエージェント２００内の発電装置３００、電力負荷装置４００及び制御装置１００は、エージェント内配電線１０４０を介して接続される。 The agent 200 includes a power generation device 300, a power load device 400, and a control device 100. In addition, the power generation device 300, the power load device 400, and the control device 100 in the agent 200 are connected via an in-agent distribution line 1040.
　エージェント２００は、各家庭や各工場等の需要家を単位として構成することもできるし、複数の需要家を含む所定の地域を単位として構成することもできる。 The agent 200 can be configured with a consumer such as each household or factory as a unit, or can be configured with a predetermined area including a plurality of consumers as a unit.
　発電装置３００は、例えば、燃料電池やマイクロガスタービン、あるいは、自然エネルギーを利用する風力発電機や太陽光発電機等の分散型発電機である。 The power generator 300 is, for example, a distributed generator such as a fuel cell, a micro gas turbine, or a wind power generator or a solar power generator that uses natural energy.
　電力負荷装置４００は、例えば需要家負荷４１０やバッテリ４２０、蓄熱装置４３０などであり、発電装置３００や商用の電力系統から供給される電力を消費する装置である。 The power load device 400 is, for example, a consumer load 410, a battery 420, a heat storage device 430, or the like, and is a device that consumes power supplied from the power generation device 300 or a commercial power system.
　需要家負荷４１０は、家庭内における各種電気機器や、工場などで稼動する各種動力装置等である。バッテリ４２０は、電気エネルギーを貯蔵する装置である。蓄熱装置４３０は、電気エネルギーを熱エネルギーの形で貯蔵する装置である。 The customer load 410 is various electric devices in the home, various power devices operating in a factory, and the like. The battery 420 is a device that stores electrical energy. The heat storage device 430 is a device that stores electrical energy in the form of heat energy.
　制御装置１００は、発電装置３００の発電量及び電力負荷装置４００の電力消費量を制御可能な装置である。例えば、制御装置１００は、所定のタイミングで、例えば３０分ごとに、自己の制御装置１００が所属するエージェント２００（以下、自エージェント２００とも記す）内の発電装置３００の発電量及び電力負荷装置４００の電力消費量をそれぞれ取得し、自エージェント２００内における電力の過不足量を求め、変圧器１０３０を制御することで商用の電力系統と自エージェント２００との間の電力の出入りを制御する。また制御装置１００は、自エージェント２００内における電力の過不足量に応じて、発電装置３００による余剰電力をバッテリ４２０や蓄熱装置４３０へ蓄えるように制御したり、バッテリ４２０に蓄えられている電力を需要家負荷４１０が利用できるように制御する。 The control device 100 is a device that can control the power generation amount of the power generation device 300 and the power consumption amount of the power load device 400. For example, the control device 100 generates the power generation amount and the power load device 400 of the power generation device 300 in the agent 200 to which the control device 100 belongs (hereinafter also referred to as the self agent 200) at a predetermined timing, for example, every 30 minutes. Each power consumption amount is acquired, an excess or deficiency amount of power in the own agent 200 is obtained, and by controlling the transformer 1030, the power input / output between the commercial power system and the own agent 200 is controlled. Further, the control device 100 controls the power generation device 300 so that the surplus power generated by the power generation device 300 is stored in the battery 420 or the heat storage device 430 according to the excess or deficiency of power in the own agent 200, or the power stored in the battery 420 is stored. Control is performed so that the customer load 410 can be used.
　また制御装置１００は、電力系統上で自エージェント２００に隣接するエージェント（以下、隣接エージェントとも記す）２００内の制御装置１００と、通信ネットワーク１０２０を介して通信可能に接続されており、自エージェント２００における電力の過不足量と、隣接エージェント２００における電力の過不足量と、に応じて、自エージェント２００における電力の過不足量の目標値を算出する。そして制御装置１００は、自エージェント２００における電力の過不足量が、この目標値に近づくように、自エージェント２００内の発電装置３００の発電量及び電力負荷装置４００の電力消費量を制御する。制御装置１００は、この目標値を、所定時間毎例えば３０分毎に更新する。 Further, the control device 100 is communicably connected to the control device 100 in an agent 200 (hereinafter also referred to as an adjacent agent) 200 adjacent to the own agent 200 on the power system via the communication network 1020. The target value of the power excess / deficiency amount in the self agent 200 is calculated according to the power excess / deficiency amount in FIG. Then, the control device 100 controls the power generation amount of the power generation device 300 and the power consumption amount of the power load device 400 in the own agent 200 so that the excess and deficiency amount of power in the own agent 200 approaches this target value. The control device 100 updates the target value every predetermined time, for example, every 30 minutes.
　なお制御装置１００は、電力システム１０００内において隣接する制御装置１００同士が通信ネットワーク１０２０を介して互いに接続された際に本実施形態で説明する各種機能を実現する装置であり、電力制御装置１１００とも記す。 The control device 100 is a device that realizes various functions described in the present embodiment when adjacent control devices 100 in the power system 1000 are connected to each other via the communication network 1020. I write.
　電力システム１０００を構成する各エージェント２００内の制御装置１００が、通信ネットワーク１０２０で接続されている様子を図２に示す。 FIG. 2 shows a state in which the control devices 100 in each agent 200 constituting the power system 1000 are connected by a communication network 1020.
　図２に示すように、各エージェント２００には識別情報（id）が付与されている。図２に示す例では、電力システム１０００は、id=0からid=7までの８つのエージェント２００を有して構成されている。 As shown in FIG. 2, each agent 200 is assigned identification information (id). In the example illustrated in FIG. 2, the power system 1000 includes eight agents 200 having id = 0 to id = 7.
　また各エージェント２００内の制御装置１００が、それぞれ算出した自エージェント２００における電力の過不足量が図２に示されている。 Also, FIG. 2 shows the excess and deficiency of power in the own agent 200 calculated by the control device 100 in each agent 200.
　例えばid=0のエージェント２００においては、5だけ電力が過剰であることを示す（”+”は、発電量の方が電力消費量よりも多く、エージェント２００内で電力が過剰であることを示す）。電力の余剰分は電力系統に供給される。またid=1のエージェント２００においては、3だけ電力が不足していることを示す（”-”は、発電量よりも電力消費量の方が多く、エージェント２００内で電力が不足していることを示す）。電力の不足分は、電力系統から補われる。 For example, in the agent 200 with id = 0, the power is excessive by 5 (“+” indicates that the amount of power generation is larger than the power consumption, and the power is excessive in the agent 200. ). The surplus power is supplied to the power system. In addition, the agent 200 with id = 1 indicates that power is insufficient by 3 ("-" indicates that the power consumption is greater than the power generation amount, and the power is insufficient in the agent 200. Showing). The shortage of power is compensated by the power system.
　また図２には、id=0からid=7までの８つのエージェント２００の電力のそれぞれの過不足量を合計すると、全体として9だけ電力が過剰であることが示されている。この場合、この過剰な電力が電力系統に逆潮流として供給されるため、電力系統の電圧や周波数が変動することになる。 FIG. 2 also shows that the total excess and deficiency of the power of the eight agents 200 from id = 0 to id = 7 is an excess of 9 as a whole. In this case, since this excessive power is supplied to the power system as a reverse power flow, the voltage and frequency of the power system fluctuate.
　本実施形態に係る電力システム１０００においては、電力系統内の各エージェント２００の電力の過不足量の合計値が０に近付くように、各エージェント２００内の制御装置１００が、それぞれエージェント２００内の電力の過不足値の目標値を算出し、各エージェント２００内の発電装置３００の発電量及び電力負荷装置４００の電力消費量を制御する。 In the power system 1000 according to the present embodiment, the control device 100 in each agent 200 causes the power in the agent 200 so that the total value of the excess and deficiency of the power in each agent 200 in the power system approaches zero. The target value of the excess / deficiency value is calculated, and the power generation amount of the power generation device 300 and the power consumption amount of the power load device 400 in each agent 200 are controlled.
　以下に詳しく述べるように、本実施形態に係る各エージェント２００内の制御装置１００は、それぞれが、自エージェント２００における電力の過不足量と、隣接エージェント２００における電力の過不足量と、に基づいて、自エージェント２００における電力の過不足量の目標値を算出する。そして制御装置１００は、自エージェント２００内における電力の過不足量が目標値に近づくように、自エージェント２００内の発電装置３００の発電量及び電力負荷装置４００の電力消費量を制御する。 As will be described in detail below, the control device 100 in each agent 200 according to the present embodiment is based on the power excess / shortage amount of the own agent 200 and the power excess / shortage amount of the adjacent agent 200. Then, the target value of the excess / deficiency amount of power in the own agent 200 is calculated. Then, the control device 100 controls the power generation amount of the power generation device 300 in the own agent 200 and the power consumption amount of the power load device 400 so that the excess or deficiency amount of power in the own agent 200 approaches the target value.
　このような態様により、電力系統の全体を統括して制御するような装置を用いることなく、電力系統の全体を最適に制御可能とすることが可能となる。 In this manner, the entire power system can be optimally controlled without using a device that controls the entire power system.
　本実施形態に係る制御装置１００のハードウェア構成の一例を図３に示す。制御装置１００は、ＣＰＵ１１０、メモリ１２０、通信装置１３０及び記憶装置１４０を有して構成される情報処理装置である。 FIG. 3 shows an example of the hardware configuration of the control device 100 according to the present embodiment. The control device 100 is an information processing device including a CPU 110, a memory 120, a communication device 130, and a storage device 140.
　ＣＰＵ１１０は制御装置１００の全体の制御を司るもので、記憶装置１４０に記憶される本実施形態に係る各種の動作を行うためのコードから構成される制御プログラム６００（詳細は後述する）をメモリ１２０に読み出して実行することにより、制御装置１００としての各種機能を実現する。 The CPU 110 governs overall control of the control device 100, and a control program 600 (details will be described later) configured by codes for performing various operations according to the present embodiment stored in the storage device 140 is stored in the memory 120. The various functions as the control device 100 are realized by reading and executing the above.
　例えば、詳細は後述するが、ＣＰＵ１１０により制御プログラム６００が実行され、メモリ１２０や通信装置１３０、記憶装置１４０等のハードウェア機器と協働することにより、通信部、電力計測部、電力受信部、目標算出部、電力制御部、が実現される。 For example, although details will be described later, the control program 600 is executed by the CPU 110, and by cooperating with hardware devices such as the memory 120, the communication device 130, and the storage device 140, a communication unit, a power measurement unit, a power reception unit, A target calculation unit and a power control unit are realized.
　メモリ１２０は例えば半導体記憶装置により構成することができる。 The memory 120 can be constituted by a semiconductor memory device, for example.
　記憶装置１４０は、例えばハードディスク装置や半導体記憶装置等により構成することができる。記憶装置１４０は、各種プログラムやデータ、テーブル等を記憶するための物理的な記憶領域を提供する装置である。記憶装置１４０は、制御装置１００に内蔵されている形態とすることもできるし、外付されている形態とすることもできる。記憶装置１４０に、本実施形態に係る制御プログラム６００や制御テーブル７００が記憶されている様子を図４に示す。 The storage device 140 can be constituted by, for example, a hard disk device or a semiconductor storage device. The storage device 140 is a device that provides a physical storage area for storing various programs, data, tables, and the like. The storage device 140 may be built in the control device 100 or may be externally attached. FIG. 4 shows how the control program 600 and the control table 700 according to the present embodiment are stored in the storage device 140.
　なお、制御プログラム６００や制御テーブル７００は、図示しない記録媒体（各種の光ディスクや磁気ディスク、半導体メモリ等）から記憶装置１４０に読み出すことで、制御装置１００に格納されるようにすることもできるし、通信装置１３０を介して通信可能に接続される他のコンピュータから取得することで、制御装置１００に格納されるようにすることもできる。なお後者の場合には、制御装置１００は記憶装置１４０を備えない構成とすることも可能である。 The control program 600 and the control table 700 can be stored in the control device 100 by reading them from a recording medium (not shown) (various optical disks, magnetic disks, semiconductor memories, etc.) to the storage device 140. It can also be stored in the control device 100 by obtaining from another computer that is communicably connected via the communication device 130. In the latter case, the control device 100 may be configured not to include the storage device 140.
　制御プログラム６００及び制御テーブル７００は、本実施形態に示す制御装置１００の各種機能や方法を実現するためのプログラム及びテーブルである。 The control program 600 and the control table 700 are a program and a table for realizing various functions and methods of the control device 100 shown in the present embodiment.
　制御テーブル７００の一例を図５に示す。なお図５に示す例は、id=1で特定されるエージェント２００内の制御装置１００が記憶している制御テーブル７００である。 An example of the control table 700 is shown in FIG. Note that the example shown in FIG. 5 is a control table 700 stored in the control device 100 in the agent 200 identified by id = 1.
　制御テーブル７００は、「日時」欄、「自エージェントid」欄、「隣接エージェントid」欄、「目標値」欄を有する。 The control table 700 has a “date and time” column, an “own agent id” column, an “adjacent agent id” column, and a “target value” column.
　「日時」欄は、日時情報が記録される。制御装置１００は、以下に述べる目標値の更新タイミングが到来すると、制御装置１００が有する図示しない計時手段から日時情報を取得して「日時」欄に記録する。 The date / time information is recorded in the “date / time” column. When the update timing of the target value described below arrives, the control device 100 acquires date / time information from a time measuring unit (not shown) included in the control device 100 and records it in the “date / time” column.
　「自エージェントid」欄は、自エージェント２００のidが記載されると共に、各日時における自エージェント２００内の電力の過不足量が記録される。図５には、2013年6月10日の13時の時点においては、自エージェント２００の電力の過不足量が-3であることが記載されている。上述したように、自エージェント２００内の電力の過不足量は、自エージェント２００内の発電装置３００の発電量及び電力負荷装置４００の電力消費量に基づいて算出される。例えば、発電装置３００の発電量から電力負荷装置４００の電力消費量を減算した値が過不足量として算出される。また制御装置１００は、この自エージェント２００内の電力の過不足量を、隣接エージェント２００に送信する。制御装置１００は、以下に述べる「隣接エージェントid」欄を参照することにより隣接エージェント２００を特定することができる。 In the “own agent id” column, the id of the own agent 200 is described, and the amount of power in and out of the own agent 200 at each date and time is recorded. FIG. 5 shows that at 13:00 on June 10, 2013, the excess and deficiency of the power of the own agent 200 is -3. As described above, the excess / deficiency amount of power in the own agent 200 is calculated based on the power generation amount of the power generation device 300 and the power consumption amount of the power load device 400 in the own agent 200. For example, a value obtained by subtracting the power consumption amount of the power load device 400 from the power generation amount of the power generation device 300 is calculated as the excess / deficiency amount. In addition, the control device 100 transmits the excess / deficiency amount of power in the own agent 200 to the adjacent agent 200. The control device 100 can identify the neighboring agent 200 by referring to the “neighboring agent id” column described below.
　「隣接エージェントid」欄は、隣接エージェントのidが記載されると共に、各日時における隣接エージェント２００内の電力の過不足量が記録される。図５に示す例（図２及び図６も同様）では、id=1で特定されるエージェント２００の隣接エージェント２００は、id=0、id=5、id=2で特定される３つである。そして、2013年6月10日の13時の時点においては、各隣接エージェント２００の電力の過不足量は、+5、+5、-2であることが記載されている。自エージェント２００の制御装置１００は、id=0、id=5、id=2で特定される３つの隣接エージェント２００の制御装置１００から、それぞれ電力の過不足量を受信し、図５に示す制御テーブルに記録する。 In the “neighboring agent id” column, the id of the neighboring agent is described, and the excess / shortage amount of power in the neighboring agent 200 at each date and time is recorded. In the example shown in FIG. 5 (the same applies to FIGS. 2 and 6), there are three neighboring agents 200 identified by id = 1, id = 0, id = 5, and id = 2. . Then, at 13:00 on June 10, 2013, it is described that the excess and deficiency of power of each adjacent agent 200 is +5, +5, and -2. The control device 100 of the own agent 200 receives the power excess / deficiency amounts from the control devices 100 of the three adjacent agents 200 identified by id = 0, id = 5, and id = 2, and performs the control shown in FIG. Record on the table.
　「目標値」欄は、「自エージェントid」欄に記載されている自エージェント２００における電力の過不足量と、「隣接エージェントid」欄に記載されている隣接エージェント２００における電力の過不足量と、に基づいて、自エージェント２００の制御装置１００が算出した、自エージェント２００における電力の過不足量の目標値が記録される。 The “target value” column includes the power excess / deficiency amount in the own agent 200 described in the “own agent id” column, and the power excess / deficiency amount in the adjacent agent 200 described in the “adjacent agent id” column. , The target value of the excess / deficiency amount of power in the own agent 200 calculated by the control device 100 of the own agent 200 is recorded.
　本実施形態においては、制御装置１００は、自エージェント２００における電力の過不足量と、隣接エージェント２００における電力の過不足量と、の平均値を、自エージェント２００における電力の過不足量から減算した値を、自エージェント２００における電力の過不足量の目標値として算出する。図５に示す例では、2013年6月10日の13時の時点においては、自エージェント２００における電力の過不足量の目標値は、-4.25と算出されている。 In the present embodiment, the control device 100 subtracts the average value of the power excess / deficiency amount in the own agent 200 and the power excess / deficiency amount in the adjacent agent 200 from the power excess / deficiency amount in the own agent 200. The value is calculated as a target value of the excess / deficiency amount of power in the own agent 200. In the example shown in FIG. 5, at 13:00 on June 10, 2013, the target value of the excess and deficiency of power in the own agent 200 is calculated as −4.25.
　そして自エージェント２００の制御装置１００は、自エージェント２００内における電力の過不足量が目標値に近づくように、自エージェント２００内の発電装置３００の発電量及び電力負荷装置４００の電力消費量を制御する。 Then, the control device 100 of the own agent 200 controls the power generation amount of the power generation device 300 and the power consumption amount of the power load device 400 in the own agent 200 so that the excess and deficiency amount of power in the own agent 200 approaches the target value. To do.
　このような処理をid=0からid=7までの８つのエージェント２００内の制御装置１００がそれぞれ実行する。 The control device 100 in each of the eight agents 200 from id = 0 to id = 7 executes such processing.
　その後３０分が経過し、2013年6月10日の13時30分になると、id=1の自エージェント２００の電力の過不足量は目標値に応じて-4.25になっており、またid=0、id=5、id=2の３つの隣接エージェント２００の電力の過不足量も、それぞれ目標値に応じて+3.67、+5.5、0になっていることが記録されている。 After 30 minutes, when the time reached 13:30 on June 10, 2013, the excess and deficiency of the power of the self-agent 200 with id = 1 was −4.25 according to the target value, and id = It is recorded that the excess and deficiency of the power of the three adjacent agents 200 with 0, id = 5, and id = 2 are also +3.67, +5.5, and 0 according to the target values, respectively.
　そのときの電力システム１０００内の各エージェント２００における電力の過不足量を図６に示す。 FIG. 6 shows the excess and deficiency of power in each agent 200 in the power system 1000 at that time.
　図６に示すように、2013年6月10日の13時30分の時点では、id=0からid=7までの８つのエージェント２００の電力のそれぞれの過不足量を合計して求めた全体としての電力の過剰量は、+1.75になっており、2013年6月10日の13時の時点の過剰量である+9から大きく改善していることが分かる。 As shown in FIG. 6, at 13:30 on June 10, 2013, the total amount obtained by summing the excess and deficiency of the power of each of the eight agents 200 from id = 0 to id = 7. The excess amount of power is +1.75, which is a significant improvement from +9, which is the excess amount at 13:00 on June 10, 2013.
　制御装置１００は、上記の処理を所定時間毎（本実施形態では３０分毎）に繰り返し行う。これにより、電力系統全体としての電力の過剰量を0に近付けていくことができる。 The control device 100 repeats the above processing every predetermined time (in this embodiment, every 30 minutes). As a result, the excess amount of power in the entire power system can approach 0.
　このように、本実施形態に係る制御装置１００を用いることにより、電力系統の全体を統括して制御するような装置を用いることなく、電力系統の全体を最適に制御可能とすることが可能となる。 Thus, by using the control device 100 according to the present embodiment, it is possible to optimally control the entire power system without using a device that controls the entire power system. Become.
　特に、自エージェント２００における電力の過不足量と、隣接エージェント２００における電力の過不足量と、の平均値を、自エージェント２００における電力の過不足量から減算した値を、自エージェント２００における電力の過不足量の目標値として算出するような簡単なアルゴリズムを実行するだけで、各制御装置１００は、電力系統の全体を統括して制御することなく、隣接エージェント２００の制御装置１００との間でデータの授受を行うだけで、電力系統の全体を最適に制御できるようになる。 In particular, a value obtained by subtracting the average value of the power excess / deficiency amount in the own agent 200 and the power excess / deficiency amount in the adjacent agent 200 from the power excess / deficiency amount in the own agent 200 is calculated. Only by executing a simple algorithm that is calculated as the target value of the excess / deficiency amount, each control device 100 does not control the entire power system and controls it with the control device 100 of the adjacent agent 200. By simply exchanging data, the entire power system can be optimally controlled.
　次に、本実施形態に係る制御装置１００が実行する処理の流れを、図７に示すフローチャートを参照しながら説明する。 Next, the flow of processing executed by the control device 100 according to the present embodiment will be described with reference to the flowchart shown in FIG.
　まず制御装置１００は、所定時刻が到来すると（例えば30分ごとの所定時刻。上記に例示した2013年6月10日の13時など）、S1000を"YES"に進む。 First, when a predetermined time arrives (for example, a predetermined time every 30 minutes; 13:00 on June 10, 2013 illustrated above), the control device 100 proceeds to SYES at “YES”.
　そして制御装置１００は、自エージェント２００における電力の過不足値を計測する(S1010)。具体的には、制御装置１００は、自エージェント２００内の発電装置３００の発電量及び電力負荷装置４００の電力消費量に基づいて自エージェント２００内の電力の過不足量を算出する。例えば制御装置１００は、発電装置３００の発電量から電力負荷装置４００の電力消費量を減算した値を過不足量として算出する。 Then, the control device 100 measures the excess / deficiency value of power in the own agent 200 (S1010). Specifically, the control device 100 calculates the excess / deficiency amount of power in the own agent 200 based on the power generation amount of the power generation device 300 in the own agent 200 and the power consumption amount of the power load device 400. For example, the control device 100 calculates a value obtained by subtracting the power consumption amount of the power load device 400 from the power generation amount of the power generation device 300 as the excess / deficiency amount.
　次に制御装置１００は、自エージェント２００における電力の過不足値を制御テーブル７００の「自エージェント」欄に記録する(S1020)。 Next, the control device 100 records the power excess / deficiency value in the own agent 200 in the “own agent” column of the control table 700 (S1020).
　そして制御装置１００は、自エージェント２００における電力の過不足値を、隣接エージェント２００に送信する（S1030）。隣接エージェント２００は、制御テーブル７００の「隣接エージェント」欄を参照することにより特定することができる。 Then, the control device 100 transmits the power excess / deficiency value of the own agent 200 to the adjacent agent 200 (S1030). The adjacent agent 200 can be identified by referring to the “adjacent agent” column of the control table 700.
　一方、制御装置１００は、隣接エージェント２００から隣接エージェント２００における電力の過不足値を取得し、制御テーブル７００の「隣接エージェント」欄に記録する(S1040)。 On the other hand, the control device 100 acquires the power excess / deficiency value in the adjacent agent 200 from the adjacent agent 200 and records it in the “adjacent agent” column of the control table 700 (S1040).
　なお、S1030の処理及びS1040の処理は、隣接エージェント２００との通信のタイミングに応じて実行される。 Note that the processing of S1030 and the processing of S1040 are executed according to the timing of communication with the adjacent agent 200.
　次に制御装置１００は、自エージェント２００における電力の過不足値の目標値を算出して、制御テーブル７００の「目標値」欄に記録する(S1050)。例えば制御装置１００は、自エージェント２００における電力の過不足量と、隣接エージェント２００における電力の過不足量と、の平均値を、自エージェント２００における電力の過不足量から減算した値を、自エージェント２００における電力の過不足量の目標値として算出する。 Next, the control device 100 calculates the target value of the power excess / deficiency value in the own agent 200 and records it in the “target value” column of the control table 700 (S1050). For example, the control device 100 subtracts, from the self agent 200, a value obtained by subtracting the average value of the power surplus / shortage amount of the self agent 200 and the power surplus / shortage amount of the adjacent agent 200 from the power surplus / shortage amount of the self agent 200. 200 is calculated as a target value of the excess or deficiency of electric power at 200.
　次に、制御装置１００は、S1000に戻り、"NO"に進む。 Next, the control device 100 returns to S1000 and proceeds to “NO”.
　そして制御装置１００は、自エージェント２００における電力の過不足値がS1050において算出した目標値になるように、発電装置３００の発電量と、電力負荷装置４００の電力消費量と、を制御する(S1060)。 Then, the control device 100 controls the power generation amount of the power generation device 300 and the power consumption amount of the power load device 400 so that the excess / deficiency value of the power in the own agent 200 becomes the target value calculated in S1050 (S1060). ).
　電力系統内の各制御装置１００が以上説明したS1000からS1060の処理を実行することにより、電力系統の全体を統括して制御するような装置を用いることなく、電力系統の全体を最適に制御可能とすることが可能となる。つまり制御装置１００は、電力系統の全体を統括して制御するような装置を用いることなく、電力系統全体としての電力の過剰量を0に近付けていくことができる。 By executing the processes from S1000 to S1060 described above by each control device 100 in the power system, the entire power system can be optimally controlled without using a device that controls the entire power system. It becomes possible. That is, the control device 100 can bring the excess amount of power in the entire power system close to 0 without using a device that controls the entire power system.
　また本実施形態に係る制御装置１００によれば、エージェント２００の追加や削除を行なう場合には、追加や削除されるエージェント２００及びこのエージェント２００に隣接するエージェント２００に関する設定だけを変更すれば良いため、新たな分散型電源の設置等に柔軟に対応でき、作業負担も大幅に軽減することができる。 In addition, according to the control device 100 according to the present embodiment, when adding or deleting the agent 200, only the setting related to the agent 200 to be added or deleted and the agent 200 adjacent to the agent 200 needs to be changed. Therefore, it is possible to flexibly cope with the installation of a new distributed power source and the work load can be greatly reduced.
　例えば図８に示すように、図２に示した電力系統の構成に対して、新たにid=8で特定されるエージェント２００をid=1で特定されるエージェント２００の隣に追加する場合には、id=8で特定されるエージェント２００の設定を新たに行う他は、id=1で特定されるエージェント２００の設定を変更するだけで済む。 For example, as shown in FIG. 8, when the agent 200 identified by id = 8 is newly added next to the agent 200 identified by id = 1 in the configuration of the power system shown in FIG. In addition to newly setting the agent 200 specified by id = 8, it is only necessary to change the setting of the agent 200 specified by id = 1.
　具体的には、図９に示すように、2013年6月10日14時から新たにid=8で特定されるエージェント２００が稼動を開始する場合には、id=1で特定されるエージェント２００では、制御テーブル７００の「隣接エージェント」欄に、新たにid=8の列を追加し、目標値の算出式を変更する。 Specifically, as shown in FIG. 9, when the agent 200 newly specified with id = 8 starts operation from 14:00 on June 10, 2013, the agent 200 specified with id = 1. Then, a column of id = 8 is newly added to the “adjacent agent” field of the control table 700, and the target value calculation formula is changed.
　このように本実施形態に係る制御装置１００によれば、電力システム１０００の構成変更にも柔軟に対応することができるので、メンテナンス負担を軽減することが可能となる。 As described above, according to the control device 100 according to the present embodiment, it is possible to flexibly cope with a configuration change of the power system 1000, so that it is possible to reduce a maintenance burden.
　なお、目標値の算出式は、上述したように、自エージェント２００における電力の過不足量と、隣接エージェント２００における電力の過不足量と、の平均値を、自エージェント２００における電力の過不足量から減算した値を、自エージェント２００における電力の過不足量の目標値として算出する以外にも、様々なものを用いることができる。 As described above, the target value calculation formula uses the average value of the power excess / deficiency amount in the own agent 200 and the power excess / deficiency amount in the adjacent agent 200 as the power excess / deficiency amount in the own agent 200. In addition to calculating the value obtained by subtracting from the target value of the excess or deficiency of power in the own agent 200, various values can be used.
　例えば図１０に示すように、制御装置１００は、自エージェント２００における電力の過不足量と、隣接エージェント２００における電力の過不足量の二乗平均値と、に基づいて、自エージェント２００における電力の過不足量の目標値を算出するようにすることもできる。 For example, as illustrated in FIG. 10, the control device 100 determines the excess of power in the own agent 200 based on the excess or deficiency amount of power in the own agent 200 and the mean square value of the excess or deficiency amount of power in the adjacent agent 200. It is also possible to calculate a target value for the shortage.
　このような態様によっても、制御装置１００は、電力系統の全体を統括して制御するような装置を用いることなく、電力系統の全体を最適に制御可能とすることが可能となる。 Also according to such an aspect, the control device 100 can optimally control the entire power system without using a device that controls the entire power system.
　なお図１０に示す例では、制御装置１００は、自エージェント２００における電力の過不足量が正の値である場合は、自エージェント２００における電力の過不足量から、隣接エージェント２００における電力の過不足量の二乗平均値を減算した値を、自エージェント２００における電力の過不足量の目標値として算出し、自エージェント２００における電力の過不足量が負の値である場合は、自エージェント２００における電力の過不足量に、隣接エージェント２００における電力の過不足量の二乗平均値を加算した値を、自エージェント２００における電力の過不足量の目標値として算出する。 In the example illustrated in FIG. 10, when the power excess / deficiency amount in the own agent 200 is a positive value, the control device 100 determines the power excess / deficiency in the adjacent agent 200 from the power excess / deficiency amount in the own agent 200. A value obtained by subtracting the root mean square value of the amount is calculated as a target value of the excess / deficiency amount of power in the own agent 200. If the excess / deficiency amount of power in the own agent 200 is a negative value, the power in the own agent 200 is calculated. A value obtained by adding the mean square value of the excess / deficiency amount of power in the adjacent agent 200 to the excess / deficiency amount of the adjacent agent 200 is calculated as a target value of the excess / deficiency amount of power in the own agent 200.
　これにより、図１０の（Ａ）で示すように、電力系統内の各エージェント２００の電力のそれぞれの過不足量を合計して求めた電力系統全体での電力の過剰量が当初は+9であったとしても、図１０の（Ｂ）で示すように、次のタイミングでは電力系統全体での電力過剰量は+1.27となり、大きく改善していることが分かる。 As a result, as shown in FIG. 10A, the excess amount of power in the entire power system obtained by summing the excess and deficiency amounts of the power of each agent 200 in the power system is initially +9. Even if it exists, as shown in (B) of FIG. 10, at the next timing, the power excess amount in the entire power system becomes +1.27, and it can be seen that it is greatly improved.
　あるいは、図１１や図１２に示すように、制御装置１００は、自エージェント２００における電力の過不足量から隣接エージェント２００における電力の過不足量を減算して得た減算値と、自エージェント２００における電力の過不足量と、に基づいて、自エージェント２００における電力の過不足量の目標値を算出するようにすることもできる。 Alternatively, as illustrated in FIG. 11 and FIG. 12, the control device 100 uses the subtraction value obtained by subtracting the excess / deficiency amount of power in the adjacent agent 200 from the excess / deficiency amount of power in the own agent 200, and Based on the excess and deficiency amount of power, the target value of the excess and deficiency amount of power in the own agent 200 can be calculated.
　このような態様によっても、制御装置１００は、電力系統の全体を統括して制御するような装置を用いることなく、電力系統の全体を最適に制御可能とすることが可能となる。 Also according to such an aspect, the control device 100 can optimally control the entire power system without using a device that controls the entire power system.
　なおこの場合、制御装置１００は、隣接エージェント２００が複数ある場合には、図１１に示すように、隣接エージェント２００毎にそれぞれ上記の減算値を求め、この減算値の中で絶対値が最小の減算値と、自エージェント２００における電力の過不足量と、に基づいて、自エージェント２００における電力の過不足量の目標値を算出するようにすることもできる。 In this case, when there are a plurality of adjacent agents 200, the control device 100 obtains the above subtraction value for each adjacent agent 200 as shown in FIG. 11, and the absolute value is the smallest among the subtraction values. Based on the subtracted value and the excess / deficiency amount of power in the own agent 200, the target value of the excess / deficiency amount of power in the own agent 200 may be calculated.
　さらにこの場合、制御装置１００は、正の値を持つ上記減算値の個数が負の値を持つ減算値の個数よりも多い場合は、自エージェント２００における電力の過不足量から絶対値が最小の減算値を減算することにより、自エージェント２００における電力の過不足量の目標値を算出し、正の値を持つ減算値の個数が負の値を持つ減算値の個数よりも少ない場合は、自エージェント２００における電力の過不足量に絶対値が最小の減算値を加算することにより、自エージェント２００における電力の過不足量の目標値を算出するようにすることができる。 Furthermore, in this case, when the number of the subtraction values having a positive value is larger than the number of subtraction values having a negative value, the control device 100 has the absolute value that is the smallest from the excess / shortage amount of power in the own agent 200. By subtracting the subtraction value, the target value of the excess or deficiency of power in the own agent 200 is calculated, and when the number of subtraction values having a positive value is smaller than the number of subtraction values having a negative value, By adding a subtraction value having a minimum absolute value to the excess or deficiency amount of power in the agent 200, the target value of the excess or deficiency amount of power in the own agent 200 can be calculated.
　なおこの場合、正の値を持つ減算値の個数と負の値を持つ減算値の個数とが同数である場合は、制御装置１００は、自エージェント２００における電力の過不足量を、自エージェント２００における電力の過不足量の目標値として算出すると良い。 In this case, when the number of subtraction values having a positive value is the same as the number of subtraction values having a negative value, the control device 100 determines the excess or deficiency of power in the own agent 200 as the own agent 200. It may be calculated as a target value of the excess or deficiency of power in
　このような態様によれば、図１１の（Ａ）で示すように、電力系統内の各エージェント２００の電力のそれぞれの過不足量を合計して求めた電力系統全体での電力の過剰量が当初は+9であったとしても、図１１の（Ｃ）で示すように、次のタイミングでは電力系統全体での電力過剰量は+8となり、さらに次のタイミングでは図１１の（Ｅ）で示すように、電力系統全体での電力過剰量は+5となり、0に近付いていることが分かる。 According to such an aspect, as shown in (A) of FIG. 11, the excess amount of power in the entire power system obtained by summing the excess and deficiency amounts of the power of each agent 200 in the power system is calculated. Even if it was initially +9, as shown in FIG. 11C, the excess power in the entire power system becomes +8 at the next timing, and further at the next timing, As shown, the power surplus in the entire power system is +5, which is close to 0.
　また制御装置１００は、図１２に示すように、隣接エージェント２００が複数ある場合には、隣接エージェント２００毎にそれぞれ上記減算値を求め、各減算値の平均値を、自エージェント２００における電力の過不足量から減算した値を、自エージェント２００における電力の過不足量の目標値を算出するようにすることもできる。 As shown in FIG. 12, when there are a plurality of adjacent agents 200, the control device 100 obtains the subtraction value for each of the adjacent agents 200, and calculates the average value of the subtraction values as the power excess in the own agent 200. It is also possible to calculate the target value of the power excess / deficiency in the own agent 200 by subtracting the value subtracted from the shortage.
　このような態様によっても、制御装置１００は、電力系統の全体を統括して制御するような装置を用いることなく、電力系統の全体を最適に制御可能とすることが可能となる。 Also according to such an aspect, the control device 100 can optimally control the entire power system without using a device that controls the entire power system.
　例えば図１２の（Ａ）で示すように、電力系統内の各エージェント２００の電力のそれぞれの過不足量を合計して求めた電力系統全体での電力の過剰量が当初は+9であったとしても、図１２の（Ｃ）で示すように、次のタイミングでは電力系統全体での電力過剰量は+5.51となり、0に近付いていることが分かる。 For example, as shown in FIG. 12A, the excess amount of power in the entire power system obtained by summing the excess and deficiency amounts of the power of the agents 200 in the power system was initially +9. However, as shown in (C) of FIG. 12, at the next timing, it is understood that the excess power amount in the entire power system is +5.51 and approaches 0.
　以上説明した様に、本実施形態に係る態様によれば、各制御装置１００が制御対象の近傍の情報のみを元に自律制御を行なうことで、電力システム１０００の全体を制御することができる。 As described above, according to the aspect according to the present embodiment, the entire power system 1000 can be controlled by each control device 100 performing autonomous control based only on information in the vicinity of the control target.
　また各制御装置１００が同じ制御プログラム６００を実行し、全体の情報を集めて制御するような装置を使用することなく、全体最適な制御を実現することができる。 Further, it is possible to realize overall optimum control without using each control device 100 by executing the same control program 600 and collecting and controlling the entire information.
　このように、各制御装置１００が制御対象近傍の情報のみを使用して制御を行なうことにより、広域情報網を初期設備として投資する必要がなく、制御が必要な箇所の通信路を随時構築していくだけで全体最適な制御を実現できる。 In this way, each control device 100 performs control using only information in the vicinity of the controlled object, so that it is not necessary to invest as a wide area information network as an initial facility, and a communication path in a place requiring control is constructed at any time. It is possible to achieve the overall optimum control just by going through.
　また新たな制御対象が追加される場合も、既に運用中の制御装置１００の制御プログラム６００や制御テーブル７００の更新も最小限で済むので、追加コストも抑制することができる。 Also, when a new control target is added, the update of the control program 600 and the control table 700 of the control apparatus 100 already in operation can be minimized, so that additional costs can be suppressed.
　このように、本実施形態に係る態様によれば、電力系統の全体を統括して制御するような装置を用いることなく、電力系統の全体を最適に制御可能とすることが可能となる。 Thus, according to the aspect according to the present embodiment, it is possible to optimally control the entire power system without using a device that controls the entire power system.
　なお上述した実施の形態は本発明の理解を容易にするためのものであり、本発明を限定して解釈するためのものではない。本発明はその趣旨を逸脱することなく変更、改良され得るとともに、本発明にはその等価物も含まれる。 The above-described embodiment is for facilitating understanding of the present invention, and is not intended to limit the present invention. The present invention can be changed and improved without departing from the gist thereof, and equivalents thereof are also included in the present invention.
