Abstract
Description
本発明は、施設内の充放電制御システムに関するものである。 The present invention relates to an in-facility charge / discharge control system.
特許文献１に開示の電力マネジメント装置においては、複数の産業車両の運行管理情報を取得するとともに運行管理情報を用いて少なくとも１台の産業車両の二次電池の充電状態に基づく給電情報を作成し、給電情報は、電力ネットワークへの給電の可否、電力ネットワークへ給電可能な時間帯、及び電力ネットワークへ給電可能な電力量の少なくとも１つを含む。 In the electric power management device disclosed in Patent Document 1, the operation management information of a plurality of industrial vehicles is acquired, and the power supply information based on the charge state of the secondary battery of at least one industrial vehicle is created by using the operation management information. , The power supply information includes at least one of the availability of power supply to the power network, the time zone in which power can be supplied to the power network, and the amount of power that can be supplied to the power network.
ところで、施設内の発電装置において、工場や複合施設等では太陽光発電を使って消費電力のピークを抑制しているが、電力が必要な夕方１８時〜２０時は太陽光発電が落ちてしまうため、目標のピークを超えてしまうことがある。通常は定置式蓄電池を使用して電力ピークの低いときに充電し、太陽光発電が落ちる夕方に放電することによって系統電力のピークを低減させることが行われている。ところが、高価な蓄電池を用意しなければならず電力設備コストの増大につながり、設置場所も確保しなければならない。また、定置式蓄電池の代用として、電動車両（業務用車、従業員車両など）を活用することも考えられるがこの種の電動車両は不定期に使用されるため安定した蓄電を行うことができない。 By the way, in the power generation equipment in the facility, the peak of power consumption is suppressed by using solar power generation in factories and complex facilities, but the solar power generation drops from 18:00 to 20:00 in the evening when power is required. Therefore, the peak of the target may be exceeded. Normally, a stationary storage battery is used to charge the battery when the power peak is low, and then discharge the battery in the evening when the photovoltaic power generation falls to reduce the peak of the system power. However, it is necessary to prepare an expensive storage battery, which leads to an increase in the cost of electric power equipment, and it is also necessary to secure an installation place. It is also conceivable to use electric vehicles (commercial vehicles, employee vehicles, etc.) as a substitute for stationary storage batteries, but this type of electric vehicle is used irregularly and cannot store stable electricity. ..
本発明の目的は、定置型蓄電池を不要にできるとともに太陽光発電装置を積極利用し、ピークカットすることができる施設内の充放電制御システムを提供することにある。 An object of the present invention is to provide an in-facility charge / discharge control system capable of eliminating the need for a stationary storage battery and actively utilizing a photovoltaic power generation device to cut peaks.
上記課題を解決するための施設内の充放電制御システムは、電動車両の電池を充放電する充放電装置と、前記充放電装置を制御する充放電制御装置と、太陽光により発電する太陽光発電装置と、施設の電力需要計画、太陽光発電計画、前記電動車両の稼働計画を記憶する記憶装置と、を備え、前記充放電制御装置は、前記記憶装置に記憶された施設の電力需要計画、太陽光発電計画から、施設の契約電力に対して電力が余剰となる時刻及び不足する時刻を算出し、前記記憶装置に記憶された電動車両の稼働計画から、充放電指令を前記充放電装置に出力することを要旨とする。 The charge / discharge control system in the facility for solving the above problems includes a charge / discharge device for charging / discharging the battery of the electric vehicle, a charge / discharge control device for controlling the charge / discharge device, and solar power generation generated by sunlight. The charge / discharge control device includes a device, a storage device for storing a facility power demand plan, a solar power generation plan, and an operation plan of the electric vehicle, and the charge / discharge control device is a facility power demand plan stored in the storage device. From the solar power generation plan, the time when the power becomes surplus and the time when the power is insufficient with respect to the contracted power of the facility is calculated, and the charge / discharge command is sent to the charge / discharge device from the operation plan of the electric vehicle stored in the storage device. The gist is to output.
これによれば、施設の電力需要計画、太陽光発電計画から、施設の契約電力に対して電力が余剰となる時刻及び不足する時刻に基づいて、電動車両の稼働計画から、充放電指令を出力することにより、電動車両の電池を施設内の電力バッファとして使用して、定置型蓄電池を不要にできる。また、太陽光発電装置を積極利用し、太陽光発電電力でピークカットすることができる。 According to this, a charge / discharge command is output from the operation plan of the electric vehicle based on the time when the power becomes surplus and the time when the power becomes insufficient with respect to the contracted power of the facility from the power demand plan and the solar power generation plan of the facility. By doing so, the battery of the electric vehicle can be used as a power buffer in the facility, and the stationary storage battery can be eliminated. In addition, it is possible to actively use the photovoltaic power generation device and cut the peak with the photovoltaic power generation.
また、施設内の充放電制御システムにおいて、前記太陽光発電計画は、過去の発電履歴と当日の天気予報から算出されるとよい。
また、施設内の充放電制御システムにおいて、前記電動車両は、産業車両または社用車であるとよい。
Further, in the charge / discharge control system in the facility, the photovoltaic power generation plan may be calculated from the past power generation history and the weather forecast of the day.
Further, in the charge / discharge control system in the facility, the electric vehicle may be an industrial vehicle or a company vehicle.
本発明によれば、定置型蓄電池を不要にできるとともに太陽光発電装置を積極利用し、ピークカットすることができる。 According to the present invention, it is possible to eliminate the need for a stationary storage battery and to actively utilize a photovoltaic power generation device to cut peaks.

次に、作用について説明する。
概略の動作として、例えば図４（ａ）、図４（ｂ）は、晴れの日の電力需要計画、バッテリフォークリフトの充放電計画であり、図４（ａ）における１２時〜１４時のように太陽光発電電力でピークカットすることができ、ピーク目標（契約電力）に対し余剰電力が生じるので、ピーク目標（契約電力）に対し太陽光発電により余裕がある１２時〜１４時において、系統電力でバッテリフォークリフト１００の電池の充電を行う。つまり、図４（ｂ）における１２時〜１４時のように系統電源の余剰電力でバッテリフォークリフト１００の電池を充電する。一方、例えば図４（ａ）における１８時〜２０時のように太陽光発電電力が低下した時（例えば夕方になり工場で大きな電力が必要となった時）には１８時〜２０時にバッテリフォークリフト１００，１０２の電池の放電を行う。つまり、図４（ｂ）における１８時〜２０時のようにバッテリフォークリフト１００，１０２の電池から放電して契約電力を超えないようにする。
Next, the action will be described.
As a schematic operation, for example, FIGS. 4 (a) and 4 (b) are a power demand plan and a battery forklift charge / discharge plan on a sunny day, as in 12:00 to 14:00 in FIG. 4 (a). The peak can be cut by the solar power generation, and surplus power is generated for the peak target (contract power). Therefore, the grid power is available from 12:00 to 14:00 when the solar power generation has a margin for the peak target (contract power). Charges the battery of the battery forklift 100. That is, the battery of the battery forklift 100 is charged with the surplus power of the system power supply as shown in FIG. 4B from 12:00 to 14:00. On the other hand, when the photovoltaic power generation is low (for example, when a large amount of power is required at the factory in the evening) as in FIG. 4A from 18:00 to 20:00, the battery forklift is lifted from 18:00 to 20:00. The batteries of 100 and 102 are discharged. That is, as in the case of 18:00 to 20:00 in FIG. 4B, the batteries of the battery forklifts 100 and 102 are discharged so as not to exceed the contract power.
図２に示すように、施設内の充放電制御システム１０の動作フローとして、上位制御装置５０において、工場内エネルギー監視システム（ＦＥＭＳ）６０から電力需要設定または履歴を得る。上位制御装置５０において、電力需要設定または履歴と、工場生産計画及び工場稼働時間とから、電力需要計画（予測）が作られる。 As shown in FIG. 2, as an operation flow of the charge / discharge control system 10 in the facility, the power demand setting or history is obtained from the energy monitoring system (FEMS) 60 in the factory in the upper control device 50. In the upper control device 50, a power demand plan (forecast) is created from the power demand setting or history, the factory production plan, and the factory operating time.
上位制御装置５０において、太陽光発電履歴と、外部機器から得た天気予報から、太陽光発電計画（予測）が作られる。つまり、太陽光発電計画は、図２に示すように、過去の発電履歴と当日の天気予報から算出される。 In the upper control device 50, a photovoltaic power generation plan (forecast) is created from the photovoltaic power generation history and the weather forecast obtained from an external device. That is, as shown in FIG. 2, the photovoltaic power generation plan is calculated from the past power generation history and the weather forecast for the day.
