Description

本発明は、単一の系統用蓄電池を複数目的の用途に活用することを可能とする複数目的制御装置に関する。   The present invention relates to a multi-purpose control device that enables a single system storage battery to be used for a multi-purpose application.

近年、太陽光発電（以下、「ＰＶ」と記す）や風力発電などの再生可能エネルギー導入が各国で積極的に進められている。ＰＶは時間、季節、天候に応じて発電出力が変動するため、太陽光発電設備を大量導入するためには需給調整が必要となる。この需給調整を実現する手段として蓄電池の活用が期待されている。蓄電池は、負荷平準化や、系統安定化制御、災害時等の非常電源など多様な用途に活用が可能であるが、高コストであることが課題となっている。   In recent years, the introduction of renewable energy such as solar power generation (hereinafter referred to as “PV”) and wind power generation has been actively promoted in each country. Since PV power generation output fluctuates according to time, season, and weather, supply and demand adjustment is required to introduce a large amount of solar power generation equipment. Utilization of storage batteries is expected as a means for realizing this supply and demand adjustment. The storage battery can be used for various purposes such as load leveling, system stabilization control, and emergency power supply in the event of a disaster, but the problem is high cost.

蓄電池を有効活用するための方法として、蓄電池寿命を考慮したピークシフト制御方法（例えば、特許文献１参照）や必要な電池容量が小さい変動抑制制御方法（例えば、特許文献２参照）が提案されている。また、ＰＶの発電量予測に基づいて前日の蓄電量を決定する制御方法（例えば、特許文献３参照）や、複数の蓄電池を一つの蓄電池と見立てて制御する方法（例えば、特許文献４参照）に関する提案もなされている。   As a method for effectively utilizing the storage battery, a peak shift control method (for example, refer to Patent Document 1) in consideration of the life of the storage battery and a fluctuation suppression control method (for example, refer to Patent Document 2) with a small required battery capacity have been proposed. Yes. Moreover, the control method (for example, refer patent document 3) which determines the electrical storage amount of the previous day based on the electric power generation amount prediction of PV, or the method (for example, refer patent document 4) which controls a some storage battery as one storage battery. Proposals have also been made.

これらの方法は、いずれも特定の効果を得るために必要な蓄電池のスペックを低減することを目的とした方法である。一方で、蓄電池を有効活用するためのアプローチとしては、一定のスペックの蓄電池から得られる効果を最大化することが考えられる。例えば、一つの電池を複数の目的に用いて得られる効果を最大化する方法である。   These methods are methods aimed at reducing the specifications of a storage battery necessary for obtaining a specific effect. On the other hand, as an approach for effectively using the storage battery, it is conceivable to maximize the effect obtained from the storage battery of a certain specification. For example, a method of maximizing the effect obtained by using one battery for a plurality of purposes.

単一の限られた容量を有する蓄電池を複数の目的に用いる方法として、ピークシフト制御と変動抑制制御を同時に行うことが考えられる。ピークシフト制御で重要となるのは蓄電容量（Ｗｈ）であり、変動抑制制御では出力容量（Ｗ）である。よって、それぞれの制御指令値の合算値を蓄電池の出力指令値とすることにより、２つの制御を同時に行うことが可能であると考えられる。   As a method of using a storage battery having a single limited capacity for a plurality of purposes, it is conceivable to simultaneously perform peak shift control and fluctuation suppression control. What is important in the peak shift control is the storage capacity (Wh), and in the fluctuation suppression control, is the output capacity (W). Therefore, it is considered that two controls can be simultaneously performed by using the sum of the control command values as the output command value of the storage battery.

しかし、この方法では合算した制御指令値を出力するために、より出力定格の大きい蓄電池用パワーコンディショナー（以下、「ＰＣＳ」と記す）が必要になってしまう。また、ピークシフトに必要な蓄電量を満たすための制御指令値に変動抑制制御の制御指令値が合算されるため、計画した蓄電量を満たせない可能性が生じ得る。   However, this method requires a storage battery power conditioner (hereinafter referred to as “PCS”) having a higher output rating in order to output the combined control command value. Further, since the control command value for fluctuation suppression control is added to the control command value for satisfying the power storage amount necessary for the peak shift, there is a possibility that the planned power storage amount cannot be satisfied.

本発明は、出力定格の大きなＰＣＳが不要で、計画した蓄電量を満たしつつ、単一の系統用蓄電池を複数目的の用途に活用することを可能とする複数目的制御装置を提供することを目的とする。   It is an object of the present invention to provide a multi-purpose control device that does not require a PCS having a large output rating and can use a single system storage battery for a multi-purpose application while satisfying a planned power storage amount. And

上述の目的を達成するため、本発明は、単一の系統用蓄電池を複数目的に活用するための制御装置であって、系統状態の情報と、複数目的の優先度情報を含む制御パラメータ情報とを取得する入力部と、取得した前記系統状態の情報及び前記制御パラメータ情報に基づいて、前記蓄電池の複数の目的を達成するために目的毎に必要な制御指令値を算出する指令値算出部と、前記指令値算出部によって算出された複数の制御指令値に対して、前記入力部で取得した前記優先度情報を考慮して前記蓄電池への出力指令値を算出する出力指令値算出部と、を備えることを特徴とする。   In order to achieve the above-mentioned object, the present invention is a control device for utilizing a single system storage battery for a plurality of purposes, and includes control state information including system state information and priority information for a plurality of purposes. And a command value calculation unit for calculating a control command value necessary for each purpose in order to achieve a plurality of purposes of the storage battery based on the obtained system state information and the control parameter information. An output command value calculation unit that calculates an output command value to the storage battery in consideration of the priority information acquired by the input unit for a plurality of control command values calculated by the command value calculation unit; It is characterized by providing.

（システムの構成）
図１は、本発明の一実施形態に係る複数目的制御装置を用いたシステムの全体構成を示すブロック図である。 (System configuration)
FIG. 1 is a block diagram showing the overall configuration of a system using a multipurpose control apparatus according to an embodiment of the present invention.

This input device 5 may be a computer assuming that an operator or the like sets information, or may be an upper energy management device.

（複数目的制御装置１の処理動作）
図２は、図１の複数目的制御装置１の処理動作を説明するためのフローチャートである。以下、図２に従って処理動作を説明する。 (Processing operation of multi-purpose control device 1)
FIG. 2 is a flowchart for explaining the processing operation of the multipurpose control apparatus 1 of FIG. The processing operation will be described below with reference to FIG.

（ステップＳ１：ピークシフト計画及び、変動抑制制御とピークシフト制御との案分係数の設定）
まず、複数目的制御装置１における入力部１０１は、計測装置４から系統状態の情報を取得し、入力装置５から作業員等により入力された制御パラメータ情報を取得し、データ保持部１０２に保存する。ここで、系統状態の情報とは、蓄電池３が電力を充放電する接続先の系統状態に関する情報であり、具体的には、図３に示すような太陽光発電装置の発電電力や図４に示すような需要家の消費電力が挙げられる。 (Step S1: Peak shift plan and setting of proportional coefficients for fluctuation suppression control and peak shift control)
First, the input unit 101 in the multi-purpose control device 1 acquires system state information from the measurement device 4, acquires control parameter information input by a worker or the like from the input device 5, and stores it in the data holding unit 102. . Here, the system state information is information related to the system state of the connection destination where the storage battery 3 charges and discharges power. Specifically, the generated power of the photovoltaic power generation apparatus as shown in FIG. The power consumption of the consumer as shown.

また、制御パラメータ情報とは、蓄電池３の複数の利用目的についての優先度情報や蓄電池３の利用目的に応じた制御情報である。本実施形態では、太陽光発電装置の発電出力の変動を抑制する目的の変動抑制制御と、電力の需要を平準化する目的のピークシフト制御の２つを行うこととしている。このため、蓄電池３の複数の利用目的についての優先度情報とは、変動抑制制御とピークシフト制御における優先度を案分係数比で示したものとする。さらに、蓄電池３の利用目的に応じた制御情報としては、例えば、ピークシフト制御に必要な充放電の計画情報が挙げられる。   Further, the control parameter information is priority information for a plurality of usage purposes of the storage battery 3 or control information according to the usage purpose of the storage battery 3. In the present embodiment, two types of fluctuation suppression control for the purpose of suppressing fluctuations in the power generation output of the photovoltaic power generation apparatus and peak shift control for the purpose of leveling the demand for power are performed. For this reason, it is assumed that the priority information for a plurality of usage purposes of the storage battery 3 indicates the priorities in the variation suppression control and the peak shift control by the proportional coefficient ratio. Furthermore, as control information according to the utilization purpose of the storage battery 3, the plan information of charging / discharging required for peak shift control is mentioned, for example.

（ステップＳ２：ピークシフト制御及び変動抑制制御に必要な指令値の算出）
次に、ピークシフト指令値算出部１０３及び変動抑制指令値算出部１０４は、それぞれ、各制御に必要な指令値を算出する。ここで、本実施形態におけるピークシフトは、需要負荷に対してＰＶが大量導入された系統を評価対象とし、ＰＶ発電による昼間の余剰電力を蓄電池３に充電し夜間に放電するものとする。 (Step S2: Calculation of command value required for peak shift control and fluctuation suppression control)
Next, the peak shift command value calculation unit 103 and the fluctuation suppression command value calculation unit 104 each calculate a command value necessary for each control. Here, in the peak shift in this embodiment, a system in which a large amount of PV is introduced with respect to a demand load is an evaluation target, and surplus power in the daytime due to PV power generation is charged in the storage battery 3 and discharged at night.

図５は、本実施形態のピークシフト制御手法を説明するグラフである。
ピークシフト指令値は、データ保持部１０２に保存されたピークシフトの充放電計画Ｓｐ（ｔ）を、実際の計測したＰＶ出力Ｓ（ｔ）と比較し、数１の式に基づいて蓄電池出力ＰＢＰを決定することによって算出する。すなわち、Ｓ（ｔ）＜Ｓｐ（ｔ）となる時刻に発生した充電計画に対する充電不足分を、Ｓ（ｔ）＞Ｓｐ（ｔ）となる時に充電計画値よりも多めに充電することによって蓄電池３の充電量を随時補正する。ここで係数ｍは、補正量を調整するための係数である。

Figure 0006189092
FIG. 5 is a graph for explaining the peak shift control method of the present embodiment.
The peak shift command value is obtained by comparing the peak shift charge / discharge plan Sp (t) stored in the data holding unit 102 with the actually measured PV output S (t), and based on the equation (1). It is calculated by determining BP . That is, the storage battery 3 is charged by charging the insufficient charging amount for the charging plan generated at the time when S (t) <Sp (t) is larger than the charging plan value when S (t)> Sp (t). Correct the amount of charge at any time. Here, the coefficient m is a coefficient for adjusting the correction amount.
Figure 0006189092

図６は、本実施形態の変動抑制制御手法を示すブロック図である。
変動抑制の指令値は、図６に基づき、制御目標をＰＶ出力の過去の一定時間の平均値（移動平均）により算出する。この制御目標と実際のＰＶ出力差分を蓄電池の出力電力指令として与え、変動分を補償する。 FIG. 6 is a block diagram showing the fluctuation suppression control method of this embodiment.
Based on FIG. 6, the command value for fluctuation suppression is calculated based on the average value (moving average) of the PV output for a fixed time in the past. This control target and the actual PV output difference are given as the output power command of the storage battery to compensate for the fluctuation.

（ステップＳ３：蓄電池３への出力指令値の算出）
さらに、エネルギー管理装置１の出力指令値算出部１０５において、各制御指令値と案分係数とを用いて蓄電池への出力指令値を算出する。
ピークシフト制御と変動抑制制御を同時に行うためには、各制御指令値の合算値を蓄電池の出力指令値とすればよい。しかし、単純に各制御指令値の合算値を出力指令値とするためには、蓄電池用ＰＣＳの定格出力を大きくする必要がある。そこで、ＰＣＳの定格出力以内で出力指令値を決定するために、変動抑制制御指令値ＰＢｆとピークシフト制御指令値ＰＢＰに案分係数ｒｆ、ｒｐを乗算して案分することで、蓄電池の出力指令値ＰＢを決定する。具体的には、ピークシフト指令値算出部１０３と変動抑制指令値算出部１０４で算出した各指令値を、数２の式を基づき蓄電池の定格出力の範囲内において、入力部１０１で入力した案分係数比で案分して決定する。

Figure 0006189092
(Step S3: Calculation of output command value to storage battery 3)
Further, the output command value calculation unit 105 of the energy management device 1 calculates the output command value to the storage battery using each control command value and the prorated coefficient.
In order to perform peak shift control and fluctuation suppression control at the same time, the sum of the control command values may be used as the output command value of the storage battery. However, in order to simply use the sum of the control command values as the output command value, it is necessary to increase the rated output of the storage battery PCS. Therefore, in order to determine the output command value within the rated output of the PCS, the variation suppression control command value P Bf and the peak shift control command value P BP are multiplied by the proportional coefficients r f and r p and divided. Then, the output command value P B of the storage battery is determined. Specifically, each command value calculated by the peak shift command value calculation unit 103 and the fluctuation suppression command value calculation unit 104 is input by the input unit 101 within the range of the rated output of the storage battery based on the formula (2). It is decided according to the proportion coefficient ratio.
Figure 0006189092

ここで、ステップＳ１で入力したピークシフト制御と変動抑制制御の案分係数比ｒｆ、ｒｐは、任意に入力してもよいが、蓄電池３の容量が一日の太陽光発電電力量より大きい場合には、ｒｆ＋ｒｐ＝１となる条件を満たす値とし、逆に蓄電池３の容量が一日の太陽光発電電力量より小さい場合には、ｒｆ=１かつｒｐ=１としてもよい。このように設定することで、蓄電池３をより効率的に使うことができる。 Here, prorated coefficient ratio r f of peak shift control and fluctuation suppression control input in step S1, r p may be input to the optional, from solar power generation amount of the capacity of the storage battery 3 day When the capacity is larger, the value satisfying the condition of r f + r p = 1 is set. Conversely, when the capacity of the storage battery 3 is smaller than the daily solar power generation amount, r f = 1 and r p = 1. Also good. By setting in this way, the storage battery 3 can be used more efficiently.

（ステップＳ４：出力指令値の蓄電池３への送信）
さらに、エネルギー管理装置１の出力部１０６において、出力指令値算出部１０５で算出した出力指令値を蓄電池３に送信する。 (Step S4: Transmission of output command value to storage battery 3)
Further, in the output unit 106 of the energy management device 1, the output command value calculated by the output command value calculation unit 105 is transmitted to the storage battery 3.

（効果）
本実施形態によれば、限られた容量を有する単一の蓄電池３を、複数の用途に活用することが可能となる。これにより、用途別に蓄電池３を用意する必要がなくなり、設備コストの低減を見込める。 (effect)
According to the present embodiment, a single storage battery 3 having a limited capacity can be used for a plurality of applications. Thereby, it is not necessary to prepare the storage battery 3 for each application, and reduction of equipment cost can be expected.

また、ピークシフト制御と変動抑制制御を同時に行う場合、変動抑制制御の充放電によってピークシフト制御の充電計画に誤差が生じる問題があるが、本実施形態の手法を用いれば、随時誤差を補正することが可能となる。   Further, when peak shift control and fluctuation suppression control are performed simultaneously, there is a problem that an error occurs in the charge plan of peak shift control due to charge / discharge of fluctuation suppression control. However, if the method of this embodiment is used, the error is corrected as needed. It becomes possible.
