Description

本発明は、電力関連設備が配置される電力管理領域と外部領域との間における電力伝送状態を制御する電力制御装置および電力制御方法に関する。 The present invention relates to a power control device and a power control method for controlling a power transmission state between a power management area in which power-related equipment is arranged and an external area.

電力関連設備が配置される電力管理領域と外部領域との間における電力伝送状態を制御する電力制御装置および電力制御方法が知られている。なお、電力関連設備としては、例えば、電力を消費する電力負荷設備と、発電を行う発電設備と、電力の蓄電および放電を行う蓄電設備と、が挙げられる。 A power control device and a power control method for controlling a power transmission state between a power management area in which power-related equipment is arranged and an external area are known. Examples of electric power-related equipment include electric power load equipment that consumes electric power, power generation equipment that generates electric power, and electric power storage equipment that stores and discharges electric power.

電力制御装置は、電力管理領域と外部領域との間における電力伝送状態の制御に加えて、電力関連設備における電力需要および電力供給を制御する。
電力制御装置は、電力管理領域での消費電力の削減要請を外部領域から受信すると、その削減要請に対応するために、電力管理領域での消費電力を低減するように、電力関連設備における電力需要および電力供給を制御する（特許文献１）。例えば、発電設備での発電電力に余裕がある場合には、その発電電力の余裕分を外部領域に供給（逆潮流電力、外部供給電力）することで、削減要請に対応することができる。 The power control device controls the power demand and power supply in the power-related equipment, in addition to controlling the power transmission state between the power management area and the external area.
When the power control device receives a power consumption reduction request in the power management area from an external area, the power demand in the power-related equipment is reduced so as to reduce the power consumption in the power management area in order to respond to the reduction request. And control the power supply (Patent Document 1). For example, when there is a margin in the power generated by the power generation facility, it is possible to respond to the reduction request by supplying the surplus power of the generated power to the external region (reverse power flow power, external power supply).

特開２０１２−２４９４７６号公報Japanese Unexamined Patent Publication No. 2012-249476

しかし、上記従来の構成においては、外部領域からの削減要請を受信した際に、発電電力に余裕がない場合には、外部領域に供給する逆潮流電力や外部供給電力を確保できないという問題がある。 However, in the above-mentioned conventional configuration, there is a problem that the reverse power flow power or the external power supply to be supplied to the external region cannot be secured if the generated power is insufficient when the reduction request from the external region is received. ..

つまり、発電設備での発電電力の供給先としては、まず、電力負荷設備が設定され、次に蓄電設備が設定され、最後に外部領域（逆潮流電力、外部供給電力）が設定される。このように、発電電力が電力負荷設備での消費電力や蓄電設備での充電電力に利用される構成においては、発電電力のうち逆潮流電力や外部供給電力として利用可能な電力が少なくなり、外部領域からの削減要請に対応できない可能性がある。 That is, as the supply destination of the generated power in the power generation equipment, the power load equipment is first set, then the power storage equipment is set, and finally the external region (reverse power flow power, external power supply power) is set. In this way, in a configuration in which the generated power is used for power consumption in the power load facility and charging power in the power storage facility, the power that can be used as reverse power flow power or external power supply among the generated power is reduced, and the power is external. It may not be possible to respond to reduction requests from the area.

そこで、本発明は、外部領域からの削減要請に対応できる可能性を高めることができる電力制御装置および電力制御方法を提供することを目的とする。 Therefore, an object of the present invention is to provide a power control device and a power control method capable of increasing the possibility of responding to a reduction request from an external region.

本発明の一態様は、電力関連設備が配置される電力管理領域と外部領域との間における電力伝送状態を制御する電力制御装置であって、電力需給制御部を備える。電力関連設備は、電力を消費する電力負荷設備と、発電を行う発電設備と、電力の蓄電および放電を行う蓄電設備と、を備えている。 One aspect of the present invention is a power control device that controls a power transmission state between a power management area in which power-related equipment is arranged and an external area, and includes a power supply / demand control unit. The electric power-related equipment includes a power load equipment that consumes electric power, a power generation equipment that generates electric power, and a power storage equipment that stores and discharges electric power.

電力需給制御部は、電力関連設備における電力需要および電力供給を制御するにあたり、電力管理領域での電力需要の削減要請を外部領域から受信すると、発電設備での発電電力の供給先として外部領域への供給電力である外部供給電力を最優先供給先に設定する。 When the power supply and demand control unit controls the power demand and power supply in the power-related equipment, when it receives a request for reduction of the power demand in the power management area from the external area, it goes to the external area as the supply destination of the generated power in the power generation facility. The external power supply, which is the power supply of, is set as the highest priority supply destination.

このように構成された電力制御装置は、外部領域からの削減要請を受信した場合には発電電力の最優先供給先に外部供給電力を設定することで、発電電力のうち外部領域に伝送可能な電力量をより多く確保できる。これにより、電力制御装置は、削減要請に対応できる可能性を高めることができる。 When the power control device configured in this way receives a reduction request from the external area, it can transmit the generated power to the external area by setting the external power supply as the highest priority supply destination of the generated power. More power can be secured. As a result, the power control device can increase the possibility of responding to the reduction request.

次に、上述の電力制御装置においては、電力需給制御部は、削減要請で要請された削減要請電力が発電電力よりも小さい場合には、発電電力のうち削減要請電力を差し引いた余裕電力の供給先として少なくとも電力負荷設備を設定してもよい。 Next, in the above-mentioned power control device, when the reduction request power requested by the reduction request is smaller than the generated power, the power supply and demand control unit supplies the surplus power obtained by subtracting the reduction request power from the generated power. At least the power load equipment may be set as a destination.

これにより、発電電力のうち余裕電力を電力負荷設備に供給することができ、外部領域から電力負荷設備に供給する電力を低減できるとともに、電力負荷設備に供給する電力の少なくとも一部を余裕電力で補うことができる。 As a result, the surplus power of the generated power can be supplied to the power load facility, the power supplied to the power load facility from the external region can be reduced, and at least a part of the power supplied to the power load facility can be supplied by the surplus power. Can be supplemented.

次に、上述の電力制御装置においては、電力需給制御部は、電力負荷設備での消費電力が余裕電力以上である場合には、蓄電設備の充電を停止してもよい。
これにより、蓄電設備の充電に要する電力を確保する必要が無くなり、電力管理領域における電力需要を低減できるため、電力管理領域での電力需給の安定化を図り易くなる。 Next, in the above-mentioned power control device, the power supply / demand control unit may stop charging the power storage equipment when the power consumption in the power load equipment is equal to or more than the marginal power.
As a result, it is not necessary to secure the electric power required for charging the power storage equipment, and the electric power demand in the electric power management area can be reduced, so that it becomes easy to stabilize the electric power supply and demand in the electric power management area.

次に、上述の電力制御装置においては、電力需給制御部は、電力負荷設備での消費電力が余裕電力よりも大きい場合には、蓄電設備からの放電を行い、蓄電設備からの放電電力の供給先として少なくとも電力負荷設備を設定してもよい。 Next, in the above-mentioned power control device, when the power consumption in the power load equipment is larger than the marginal power, the power supply / demand control unit discharges the power storage equipment and supplies the discharged power from the power storage equipment. At least the power load equipment may be set as a destination.

これにより、発電電力（詳細には余裕電力）に加えて蓄電設備からの放電電力を電力負荷設備に供給することができ、電力負荷設備の稼働に必要な消費電力を確保し易くなる。
次に、上述の電力制御装置においては、電力需給制御部は、電力負荷設備での消費電力が余裕電力よりも小さい場合には、余裕電力の供給先として少なくとも蓄電設備の充電電力を設定してもよい。 As a result, in addition to the generated power (specifically, the surplus power), the discharge power from the power storage equipment can be supplied to the power load equipment, and it becomes easy to secure the power consumption required for the operation of the power load equipment.
Next, in the above-mentioned power control device, when the power consumption of the power load equipment is smaller than the margin power, the power supply / demand control unit sets at least the charging power of the power storage equipment as the supply destination of the margin power. May be good.

これにより、余裕電力を蓄電設備に蓄えることができ、電力不足時には蓄電設備から放電することで、電力不足を解消できる。
次に、上述の電力制御装置においては、電力需給制御部は、削減要請で要請された削減要請電力が発電電力以上である場合には、蓄電設備の充電を停止するとともに蓄電設備からの放電を行い、蓄電設備からの放電電力の供給先として、電力負荷設備での消費電力および外部供給電力のうち少なくとも一方を設定してもよい。 As a result, the surplus power can be stored in the power storage equipment, and when the power is insufficient, the power storage equipment is discharged to solve the power shortage.
Next, in the above-mentioned power control device, when the reduction request power requested by the reduction request is equal to or more than the generated power, the power supply / demand control unit stops charging the power storage equipment and discharges from the power storage equipment. Then, at least one of the power consumption in the power load facility and the external power supply may be set as the supply destination of the discharge power from the power storage facility.

これにより、発電電力では削減要請電力を確保できない場合であっても、削減要請電力から発電電力を差し引いた不足分の少なくとも一部を蓄電設備の放電電力で補うことができるため、削減要請に対応できる可能性を高めることができる。 As a result, even if the reduced power cannot be secured with the generated power, at least a part of the shortage obtained by subtracting the generated power from the reduced requested power can be supplemented by the discharge power of the power storage facility, so that the reduction request can be met. You can increase the possibility of being able to do it.

本発明の他の態様は、電力関連設備が配置される電力管理領域と外部領域との間における電力伝送状態を制御する電力制御方法であって、電力関連設備における電力需要および電力供給を制御するにあたり、電力管理領域での電力需要の削減要請を外部領域から受信すると、発電設備での発電電力の供給先として外部領域への供給電力である外部供給電力を最優先供給先に設定する。電力関連設備は、電力を消費する電力負荷設備と、発電を行う発電設備と、電力の蓄電および放電を行う蓄電設備と、を備えている。 Another aspect of the present invention is a power control method for controlling a power transmission state between a power management area in which power-related equipment is arranged and an external area, and controls power demand and power supply in the power-related equipment. When a request for reduction of power demand in the power management area is received from the external area, the external power supply, which is the power supplied to the external area, is set as the highest priority supply destination as the power generation destination in the power generation facility. The electric power-related equipment includes a power load equipment that consumes electric power, a power generation equipment that generates electric power, and a power storage equipment that stores and discharges electric power.

この電力制御方法は、上述の電力制御装置と同様に、発電電力のうち外部領域に伝送可能な電力量をより多く確保できるため、削減要請に対応できる可能性を高めることができる。 Similar to the above-mentioned power control device, this power control method can secure a larger amount of generated power that can be transmitted to the external region, and thus can increase the possibility of responding to a reduction request.

Further, the power generation facility 33 is configured so that the amount of power generation can be adjusted depending on the power generation form thereof (for example, a power generation facility using biomass or geothermal heat, a power generation facility using a small generator as a power source, etc.). , The amount of power generation can be adjusted based on a command from the power control device 20 or the like.

ＤＲ指令を受信した電力制御装置２０は、未来の需給管理期間のうちＤＲ指令により定められた制限指令期間に対して、ＤＲ制御を行うためのＤＲ設定を行う。ＤＲ設定した期間（制限指令期間）が到来すると、電力制御装置２０は、ＤＲ指令により定められた電力削減量に応じた電力需要を削減するように、電力関連設備（負荷設備３１、蓄電設備３２、発電設備３３のそれぞれ）の動作状態を制御する。 The power control device 20 that has received the DR command sets the DR for performing the DR control for the limit command period specified by the DR command in the future supply and demand management period. When the DR set period (limit command period) arrives, the power control device 20 reduces the power demand according to the power reduction amount specified by the DR command, and the power-related equipment (load equipment 31, power storage equipment 32). , Each of the power generation equipment 33) is controlled.

また、電力制御装置２０は、ＣＥＭＳ１０や電力会社側装置との間で各種情報の送受信を行う。例えば、電力制御装置２０は、上述のように、ＣＥＭＳ１０からＤＲ指令などを受信している。また、電力制御装置２０は、発電所に関する各種情報（発電量など）を、電力会社側装置から受信している。 Further, the power control device 20 transmits and receives various information to and from the CEMS 10 and the device on the power company side. For example, the power control device 20 receives a DR command or the like from the CEMS 10 as described above. Further, the electric power control device 20 receives various information (such as the amount of power generation) about the power plant from the electric power company side device.

なお、電力制御装置２０は、発電所に関する各種情報（発電量など）を、ＣＥＭＳ１０を介して受信してもよい。つまり、ＣＥＭＳ１０が、発電所に関する各種情報（発電量など）を、電力会社側装置から受信して記憶している場合には、電力制御装置２０は、発電所に関する各種情報（発電量など）を、ＣＥＭＳ１０を介して受信することが可能である。 The power control device 20 may receive various information (such as the amount of power generation) about the power plant via the CEMS 10. That is, when the CEMS 10 receives and stores various information about the power plant (power generation amount, etc.) from the electric power company side device, the power control device 20 receives various information about the power plant (power generation amount, etc.). , Can be received via CEMS 10.

さらに、電力制御装置２０は、図示しない通信経路を介して、他の電力管理領域３０における電力制御装置２０との間で各種情報の送受信を行う。例えば、電力制御装置２０は、他の電力管理領域３０に備えられる電力関連設備（負荷設備３１、蓄電設備３２、発電設備３３のそれぞれ）に関する各種情報（発電量など）を、他の電力管理領域３０における電力制御装置２０から受信している。 Further, the power control device 20 transmits and receives various information to and from the power control device 20 in another power management area 30 via a communication path (not shown). For example, the power control device 20 provides various information (power generation amount, etc.) regarding power-related equipment (load equipment 31, power storage equipment 32, and power generation equipment 33) provided in the other power management area 30 to the other power management area. It is received from the power control device 20 in 30.

電力制御装置２０は、上述のとおり、電力管理領域３０における電力関連設備（負荷設備３１、蓄電設備３２、発電設備３３のそれぞれ）の電力需給管理を実行しており、例えば、ＤＲ指令を受信していない場合には、図２に示すような電力需給状態となるように電力関連設備を制御する。図２では、発電設備３３での発電電力ＰＧを、負荷設備３１に供給するための負荷用電力Ｐｇ１と、蓄電設備３２に供給するための蓄電用電力Ｐｇ２と、電力線１７を介して外部（商用電源１６、他の電力管理領域３０、個別負荷３４など、）に供給するための外部供給電力Ｐｇ３と、に分配する電力供給状態を表している（ＰＧ＝Ｐｇ１＋Ｐｇ２＋Ｐｇ３）。 As described above, the power control device 20 executes power supply and demand management of power-related equipment (load equipment 31, power storage equipment 32, and power generation equipment 33, respectively) in the power management area 30, and receives, for example, a DR command. If not, the power-related equipment is controlled so as to be in the power supply / demand state as shown in FIG. In FIG. 2, the load power Pg1 for supplying the power generation power PG of the power generation facility 33 to the load facility 31, the power storage power Pg2 for supplying the power storage facility 32, and the external power (commercial) via the power line 17. It represents the power supply state to be distributed to the external power supply Pg3 for supplying to the power source 16, another power management area 30, the individual load 34, etc. (PG = Pg1 + Pg2 + Pg3).

このとき、電力制御装置２０は、発電電力ＰＧの分配先を決定する際の優先順位としては、負荷用電力Ｐｇ１を第１優先とし、蓄電用電力Ｐｇ２を第２優先とし、外部供給電力Ｐｇ３を第３優先としている。このような優先順位に基づいて自己の電力管理領域３０における電力需給状態を制御することで、まずは負荷設備３１の稼働を確保し、次に蓄電設備３２への蓄電を行い、その上での余裕電力を外部供給電力Ｐｇ３として外部に送電している。 At this time, the power control device 20 prioritizes the load power Pg1 as the first priority, the storage power Pg2 as the second priority, and the external power supply Pg3 as the priority when determining the distribution destination of the generated power PG. The third priority is given. By controlling the power supply and demand state in the own power management area 30 based on such a priority, the operation of the load equipment 31 is first secured, and then the power storage equipment 32 is charged with power, and the margin on that is obtained. The electric power is transmitted to the outside as the externally supplied electric power Pg3.

なお、外部供給電力Ｐｇ３は、例えば、電力管理領域３０から商用電源１６への逆潮流電力や、自己の電力管理領域３０から他の電力管理領域３０への供給する救援電力などとして利用できる。 The externally supplied power Pg3 can be used, for example, as reverse power flow power from the power management area 30 to the commercial power source 16, rescue power supplied from the own power management area 30 to another power management area 30, and the like.

［１−３．ＤＲ対応制御処理］
電力制御装置２０（ＢＥＭＳ２０）は、コンピュータシステムにより実現される機能の１つとして、各種処理を実行する制御部２１を備えている。制御部２１が実行する各種制御処理のうちＤＲ対応制御処理について説明する。 [1-3. DR compatible control processing]
The power control device 20 (BEMS 20) includes a control unit 21 that executes various processes as one of the functions realized by the computer system. Among the various control processes executed by the control unit 21, the DR-compatible control process will be described.

ＤＲ対応制御処理は、電力制御装置２０（制御部２１）が管理装置１０（ＣＥＭＳ１０）からＤＲ指令を受信した際に電力管理領域３０における電力関連設備（負荷設備３１、蓄電設備３２、発電設備３３のそれぞれ）の電力需給状況を制御するための処理である。ＤＲ対応制御処理は、電力制御装置２０が起動されると、予め定められた実行周期（本実施形態では、１分毎）で制御部２１での処理として実行される。 In the DR-compatible control process, when the power control device 20 (control unit 21) receives a DR command from the management device 10 (CEMS10), the power-related equipment (load equipment 31, power storage equipment 32, power generation equipment 33) in the power management area 30 It is a process for controlling the power supply and demand situation of each of). When the power control device 20 is activated, the DR-compatible control process is executed as a process in the control unit 21 at a predetermined execution cycle (every minute in this embodiment).

図３は、ＤＲ対応制御処理の処理内容を表したフローチャートである。
ＤＲ対応制御処理が起動されると、まず、Ｓ１１０（Ｓはステップを表す）では、ＣＥＭＳ１０からＤＲ指令を受信したか否かを判断し、肯定判定するとＳ１２０に移行し、否定判定すると本処理を終了する。 FIG. 3 is a flowchart showing the processing contents of the DR-compatible control process.
When the DR correspondence control process is activated, first, in S110 (S represents a step), it is determined whether or not a DR command has been received from CEMS10, and if affirmative determination is made, the process proceeds to S120, and if a negative determination is made, this process is performed. finish.

Ｓ１１０で肯定判定されてＳ１２０に移行すると、Ｓ１２０では、発電電力ＰＧの分配先を決定する際の優先順位として、外部供給電力Ｐｇ３を第１優先として設定する。つまり、発電電力ＰＧの最優先供給先として外部供給電力Ｐｇ３を設定する。 When the affirmative determination is made in S110 and the process shifts to S120, in S120, the external power supply Pg3 is set as the first priority as the priority when determining the distribution destination of the generated power PG. That is, the external power supply Pg3 is set as the highest priority supply destination of the power generation power PG.

次のＳ１３０では、発電電力ＰＧとＤＲ指令に基づく削減要請電力ＰＤＲとを比較するにあたり、発電電力ＰＧが削減要請電力ＰＤＲよりも大きいか否かを判断し、発電電力ＰＧが削減要請電力ＰＤＲよりも大きい場合には肯定判定してＳ１５０に移行し、発電電力ＰＧが削減要請電力ＰＤＲ以下である場合には否定判定してＳ１４０に移行する。 In the next S130, when comparing the generated power PG and the reduction request power PDR based on the DR command, it is determined whether or not the generated power PG is larger than the reduction request power PDR, and the generated power PG is from the reduction request power PDR. If it is large, a positive judgment is made and the transition to S150 is performed, and if the generated power PG is equal to or less than the reduction request power PDR, a negative judgment is made and the transition to S140 is performed.

Ｓ１３０で否定判定されてＳ１４０に移行すると、Ｓ１４０では、蓄電設備３２の充電を停止し、蓄電設備３２の放電を実行する。これにより、蓄電設備３２からの放電電力の供給先として、負荷設備３１での消費電力Ｌおよび外部供給電力Ｐｇ３（削減要請電力ＰＤＲ）のうち少なくとも一方を設定する。このとき、蓄電設備３２が放電する放電電力Ｂｏｕｔは、負荷設備３１の消費電力Ｌと削減要請電力ＰＤＲとの合計値から発電電力ＰＧを差し引いた値となる（Ｂｏｕｔ＝Ｌ＋ＰＤＲ−ＰＧ）。 When a negative determination is made in S130 and the process shifts to S140, charging of the power storage equipment 32 is stopped and discharge of the power storage equipment 32 is executed in S140. As a result, at least one of the power consumption L of the load equipment 31 and the external power supply Pg3 (reduction request power PDR) is set as the supply destination of the discharge power from the power storage equipment 32. At this time, the discharge power Bout discharged by the power storage facility 32 is a value obtained by subtracting the generated power PG from the total value of the power consumption L of the load facility 31 and the reduction request power PDR (Bout = L + PDR-PG).

Ｓ１３０で肯定判定されてＳ１５０に移行すると、Ｓ１５０では、発電電力ＰＧの分配先を決定する際の優先順位として、負荷用電力Ｐｇ１を第２優先として設定する。つまり、発電電力ＰＧの供給先として、外部供給電力Ｐｇ３を第１優先として設定し、負荷用電力Ｐｇ１を第２優先として設定する。換言すれば、発電電力ＰＧから削減要請電力ＰＤＲ（外部供給電力Ｐｇ３）を差し引いた余裕電力Ｐａ１（＝ＰＧ−ＰＤＲ）の最優先供給先として負荷用電力Ｐｇ１を設定する。 When the affirmative determination is made in S130 and the process shifts to S150, in S150, the load power Pg1 is set as the second priority as the priority when determining the distribution destination of the generated power PG. That is, as the supply destination of the generated power PG, the external power supply Pg3 is set as the first priority, and the load power Pg1 is set as the second priority. In other words, the load power Pg1 is set as the highest priority supply destination of the surplus power Pa1 (= PG-PDR) obtained by subtracting the reduction request power PDR (external power supply Pg3) from the generated power PG.

次のＳ１６０では、負荷設備３１の消費電力Ｌが発電電力ＰＧから削減要請電力ＰＤＲ（外部供給電力Ｐｇ３）を差し引いた余裕電力Ｐａ１（＝ＰＧ−ＰＤＲ）以上であるか否かを判断し、肯定判定するとＳ１７０に移行し、否定判定するとＳ２１０に移行する。 In the next S160, it is determined whether or not the power consumption L of the load equipment 31 is equal to or more than the margin power Pa1 (= PG-PDR) obtained by subtracting the reduction request power PDR (external power supply Pg3) from the generated power PG, and affirms it. If it is determined, it shifts to S170, and if it is negative, it shifts to S210.

Ｓ１６０で肯定判定されてＳ１７０に移行すると、Ｓ１７０では、蓄電設備３２の充電を停止する。
次のＳ１８０では、負荷設備３１の消費電力Ｌが発電電力ＰＧから削減要請電力ＰＤＲ（外部供給電力Ｐｇ３）を差し引いた余裕電力Ｐａ１（＝ＰＧ−ＰＤＲ）と等しいか否かを判断し、肯定判定するとＳ１９０に移行し、否定判定するとＳ２００に移行する。 When the affirmative determination is made in S160 and the process shifts to S170, charging of the power storage equipment 32 is stopped in S170.
In the next S180, it is determined whether or not the power consumption L of the load equipment 31 is equal to the margin power Pa1 (= PG-PDR) obtained by subtracting the reduction request power PDR (external power supply Pg3) from the generated power PG, and affirmative judgment is made. Then, it shifts to S190, and if it is determined to be negative, it shifts to S200.

Ｓ１８０で肯定判定されてＳ１９０に移行すると、Ｓ１９０では、蓄電設備３２の状態を放電しない状態に設定する。これにより、蓄電設備３２は、充電をせず、かつ放電をしない状態となる。 When an affirmative determination is made in S180 and the transition to S190 occurs, the state of the power storage equipment 32 is set to a non-discharging state in S190. As a result, the power storage equipment 32 is in a state of not being charged and not being discharged.

Ｓ１８０で否定判定されてＳ２００に移行すると、Ｓ２００では、蓄電設備３２の状態を放電状態に設定する。これにより、蓄電設備３２からの放電電力Ｂｏｕｔの供給先として負荷設備３１が設定される。 When a negative determination is made in S180 and the process shifts to S200, the state of the power storage equipment 32 is set to the discharge state in S200. As a result, the load equipment 31 is set as the supply destination of the discharge power Bout from the power storage equipment 32.

このとき、蓄電設備３２が放電する放電電力Ｂｏｕｔは、負荷設備３１の消費電力Ｌと削減要請電力ＰＤＲとの合計値から発電電力ＰＧを差し引いた値となる（Ｂｏｕｔ＝Ｌ＋ＰＤＲ−ＰＧ）。このときの電力需給状態を図４に示す。図４では、発電設備３３での発電電力ＰＧを、負荷用電力Ｐｇ１と外部供給電力Ｐｇ３とに分配するように設定する（ＰＧ＝Ｐｇ１＋Ｐｇ３）とともに、放電電力Ｂｏｕｔを負荷設備３１に供給する負荷用放電電力Ｐｂ１として設定（Ｂｏｕｔ＝Ｐｂ１）した電力供給状態を表している。 At this time, the discharge power Bout discharged by the power storage facility 32 is a value obtained by subtracting the generated power PG from the total value of the power consumption L of the load facility 31 and the reduction request power PDR (Bout = L + PDR-PG). The power supply and demand state at this time is shown in FIG. In FIG. 4, the generated power PG in the power generation facility 33 is set to be distributed to the load power Pg1 and the external power supply Pg3 (PG = Pg1 + Pg3), and the discharge power Bout is supplied to the load facility 31 for the load. It represents the power supply state set as the discharge power Pb1 (Bout = Pb1).

なお、図４では、負荷用電力Ｐｇ１と負荷用放電電力Ｐｂ１との合計値が消費電力Ｌと等しい場合の電力需給状態を表している（Ｌ＝Ｐｇ１＋Ｐｂ１）。また、図４では、蓄電設備３２が放電可能な電力量が負荷設備３１の消費電力Ｌ以上である場合を表している。 Note that FIG. 4 shows a power supply / demand state when the total value of the load power Pg1 and the load discharge power Pb1 is equal to the power consumption L (L = Pg1 + Pb1). Further, FIG. 4 shows a case where the amount of electric power that can be discharged by the power storage equipment 32 is equal to or more than the power consumption L of the load equipment 31.

Ｓ１６０で否定判定されてＳ２１０に移行すると、Ｓ２１０では、発電電力ＰＧのうち余裕電力Ｐａ１（＝ＰＧ−ＰＤＲ）による蓄電設備３２の充電を継続する。つまり、余裕電力Ｐａ１の供給先として蓄電設備３２の充電電力Ｂｉｎを設定する。このとき、蓄電設備３２に充電される充電電力Ｂｉｎは、発電電力ＰＧから負荷設備３１の消費電力Ｌおよび削減要請電力ＰＤＲを差し引いた値となる（Ｂｉｎ＝ＰＧ−ＰＤＬ−Ｌ）。 When a negative determination is made in S160 and the transition to S210 occurs, in S210, charging of the power storage facility 32 by the surplus power Pa1 (= PG-PDR) of the generated power PG is continued. That is, the charging power Bin of the power storage equipment 32 is set as the supply destination of the spare power Pa1. At this time, the charging power Bin charged in the power storage equipment 32 is a value obtained by subtracting the power consumption L of the load equipment 31 and the reduction request power PDR from the generated power PG (Bin = PG-PDL-L).

Ｓ１１０で否定判定されるか、Ｓ１４０、Ｓ１９０、Ｓ２００、Ｓ２１０のいずれかのステップが終了すると、本処理が終了する。
このようなＤＲ対応制御処理を実行する電力制御装置２０（制御部２１）は、ＤＲ指令を受信したか否かを判定し、ＤＲ指令を受信した場合には（Ｓ１１０で肯定判定）、発電電力ＰＧの分配先として、外部供給電力Ｐｇ３を第１優先として設定する（Ｓ１２０）。そして、制御部２１は、発電電力ＰＧと削減要請電力ＰＤＲとの比較結果や、消費電力Ｌと余裕電力Ｐａ１（＝ＰＧ−ＰＤＲ）との比較結果などに基づいて、蓄電設備３２の充電状態・放電状態を制御する。 This process ends when a negative determination is made in S110 or when any of the steps S140, S190, S200, and S210 is completed.
The power control device 20 (control unit 21) that executes such a DR-compatible control process determines whether or not a DR command has been received, and if the DR command is received (affirmative determination in S110), the generated power. The external power supply Pg3 is set as the first priority as the distribution destination of the PG (S120). Then, the control unit 21 determines the charging state of the power storage equipment 32 based on the comparison result between the generated power PG and the reduction request power PDR, the comparison result between the power consumption L and the surplus power Pa1 (= PG-PDR), and the like. Control the discharge state.

［１−４．効果］
以上説明したように、本実施形態の電力制御装置２０（ＢＥＭＳ２０）は、ＤＲ対応制御処理を実行する制御部２１を備えている。 [1-4. effect]
As described above, the power control device 20 (BEMS20) of the present embodiment includes a control unit 21 that executes DR-compatible control processing.

制御部２１は、電力関連設備（負荷設備３１、蓄電設備３２、発電設備３３）における電力需要および電力供給を制御するにあたり、ＤＲ指令をＣＥＭＳ１０から受信すると（Ｓ１１０で肯定判定）、発電設備３３での発電電力ＰＧの供給先として削減要請電力ＰＤＲ（外部供給電力Ｐｇ３）を最優先供給先に設定する（Ｓ１２０）。 When the control unit 21 receives a DR command from the CEMS 10 (affirmative judgment in S110) in controlling the power demand and power supply in the power-related equipment (load equipment 31, power storage equipment 32, power generation equipment 33), the power generation equipment 33 As the supply destination of the generated power PG of the above, the reduction request power PDR (external power supply Pg3) is set as the highest priority supply destination (S120).

この電力制御装置２０は、ＳＥＭＳ１０からのＤＲ指令を受信した場合には発電電力ＰＧの最優先供給先に削減要請電力ＰＤＲ（外部供給電力Ｐｇ３）を設定することで、発電電力ＰＧのうち外部領域（商用電源１６、他の電力管理領域３０、個別負荷３４）に伝送可能な電力量をより多く確保できる。 When the power control device 20 receives the DR command from the SEMS 10, the power control device 20 sets the reduction request power PDR (external power supply Pg3) as the highest priority supply destination of the power generation power PG, thereby setting the external region of the power generation power PG. A larger amount of power that can be transmitted to (commercial power source 16, other power management area 30, individual load 34) can be secured.

よって、電力制御装置２０は、ＣＥＭＳ１０からのＤＲ指令に対応できる可能性を高めることができる。
次に、電力制御装置２０の制御部２１は、ＤＲ指令で要請された削減要請電力ＰＤＲが発電電力ＰＧよりも小さい場合には（Ｓ１３０で肯定判定）、発電電力ＰＧのうち削減要請電力ＰＤＲを差し引いた余裕電力Ｐａ１（＝ＰＧ−ＰＤＲ）の供給先として少なくとも負荷設備３１を設定する（Ｓ１５０）。 Therefore, the power control device 20 can increase the possibility of responding to the DR command from the CEMS 10.
Next, when the reduction request power PDR requested by the DR command is smaller than the generated power PG (affirmative judgment in S130), the control unit 21 of the power control device 20 determines the reduction request power PDR among the generated power PG. At least the load facility 31 is set as the supply destination of the deducted surplus power Pa1 (= PG-PDR) (S150).

これにより、発電電力ＰＧのうち余裕電力Ｐａ１を負荷設備３１に供給することができ、商用電源１６などから負荷設備３１に供給する電力を低減できるとともに、負荷設備３１に供給する電力の少なくとも一部を余裕電力Ｐａ１で補うことができる。 As a result, the surplus power Pa1 of the generated power PG can be supplied to the load equipment 31, the power supplied from the commercial power source 16 or the like to the load equipment 31 can be reduced, and at least a part of the power supplied to the load equipment 31. Can be supplemented with the surplus power Pa1.

次に、電力制御装置２０の制御部２１は、負荷設備３１での消費電力Ｌが余裕電力Ｐａ１（＝ＰＧ−ＰＤＲ）以上である場合には（Ｓ１６０で肯定判定）、蓄電設備３２の充電を停止する（Ｓ１７０）。これにより、蓄電設備３２の充電に要する電力を確保する必要が無くなり、電力管理領域３０における電力需要を低減できるため、電力管理領域３０での電力需給の安定化を図り易くなる。 Next, when the power consumption L of the load equipment 31 is equal to or greater than the marginal power Pa1 (= PG-PDR) (positive determination in S160), the control unit 21 of the power control device 20 charges the power storage equipment 32. Stop (S170). As a result, it is not necessary to secure the electric power required for charging the power storage equipment 32, and the electric power demand in the electric power management area 30 can be reduced, so that it becomes easy to stabilize the electric power supply and demand in the electric power management area 30.

次に、電力制御装置２０の制御部２１は、負荷設備３１での消費電力Ｌが余裕電力Ｐａ１（＝ＰＧ−ＰＤＲ）よりも大きい場合には（Ｓ１６０で肯定判定、かつＳ１８０で否定判定）、蓄電設備３２からの放電を行い、蓄電設備３２からの放電電力Ｂｏｕｔの供給先として負荷設備３１を設定する（Ｓ２００）。 Next, when the power consumption L of the load equipment 31 is larger than the marginal power Pa1 (= PG-PDR), the control unit 21 of the power control device 20 determines that the power consumption is positive in S160 and negative in S180). Discharging from the power storage equipment 32 is performed, and the load equipment 31 is set as a supply destination of the discharge power Bout from the power storage equipment 32 (S200).

これにより、発電電力ＰＧ（詳細には余裕電力Ｐａ１（＝負荷用電力Ｐｇ１））に加えて、蓄電設備３２からの放電電力Ｂｏｕｔ（負荷用放電電力Ｐｂ１）を、負荷設備３１に供給することができ、負荷設備３１の稼働に必要な消費電力Ｌを確保し易くなる。 As a result, in addition to the generated power PG (specifically, the margin power Pa1 (= load power Pg1)), the discharge power Bout (load discharge power Pb1) from the power storage facility 32 can be supplied to the load facility 31. This makes it easier to secure the power consumption L required for the operation of the load facility 31.

次に、電力制御装置２０の制御部２１は、負荷設備３１での消費電力Ｌが余裕電力Ｐａ１よりも小さい場合には（Ｓ１６０で否定判定）、余裕電力Ｐａ１の供給先として蓄電設備３２の充電電力Ｂｉｎを設定している（Ｓ２１０）。 Next, when the power consumption L of the load equipment 31 is smaller than the margin power Pa1 (negative determination in S160), the control unit 21 of the power control device 20 charges the power storage equipment 32 as a supply destination of the margin power Pa1. The power bin is set (S210).

これにより、余裕電力Ｐａ１を蓄電設備３２に蓄えることができ、電力不足時には蓄電設備３２から放電することで、電力不足を解消できる。
次に、電力制御装置２０の制御部２１は、ＤＲ指令で要請された削減要請電力ＰＤＲが発電電力ＰＧ以上である場合には（Ｓ１３０で否定判定）、蓄電設備３２の充電を停止するとともに蓄電設備３２からの放電を行い、蓄電設備３２からの放電電力の供給先として、負荷設備３１での消費電力Ｌおよび外部供給電力Ｐｇ３（削減要請電力ＰＤＲ）のうち少なくとも一方を設定する（Ｓ１４０）。 As a result, the surplus power Pa1 can be stored in the power storage facility 32, and when the power is insufficient, the power storage facility 32 can be discharged to solve the power shortage.
Next, when the reduction request power PDR requested by the DR command is equal to or greater than the generated power PG (negative determination in S130), the control unit 21 of the power control device 20 stops charging the power storage facility 32 and stores the power. Discharge from the equipment 32 is performed, and at least one of the power consumption L of the load equipment 31 and the external power supply Pg3 (reduction request power PDR) is set as the supply destination of the discharge power from the power storage equipment 32 (S140).

これにより、発電電力ＰＧでは削減要請電力ＰＤＲを確保できない場合であっても、削減要請電力ＰＤＲから発電電力ＰＧを差し引いた不足分の少なくとも一部を蓄電設備３２の放電電力Ｂｏｕｔで補うことができるため、ＤＲ指令に対応できる可能性を高めることができる。 As a result, even if the power generation power PG cannot secure the reduction request power PDR, at least a part of the shortage obtained by subtracting the power generation power PG from the reduction request power PDR can be supplemented by the discharge power Bout of the power storage facility 32. Therefore, the possibility of responding to the DR command can be increased.
