Title (EN) POWER STORAGE SYSTEM AND CONTROL DEVICE
(FR) SYSTÈME DE STOCKAGE D'ÉNERGIE ET DISPOSITIF DE COMMANDE
(JA) 蓄電システム、管理装置
Abstract:
(EN) In a power storage system (1), a control unit (50m) calculates the overall State of Power (SOP) of a plurality of power storage blocks (10-30) on the basis of the SOP of each individual power storage block in the plurality of power storage blocks (10-30) connected in parallel, and sets the calculated overall SOP to the upper limit value for power or current for charging and/or discharging of a power conversion unit (60). When at least one of a plurality of switches (S1-S3) is turned off and at least one (30) of the plurality of power storage blocks (10-30) is separated, the control unit (50m) calculates the overall SOP of the remaining power storage blocks (10, 20) on the basis of current variations of each of the remaining power storage blocks (10, 20), and sets the upper limit value for the power or current flowing to the power conversion unit (60).
(FR) Dans un système de stockage d'énergie (1), une unité de commande (50m) calcule l'état de puissance (SOP) global d'une pluralité de blocs de stockage d'énergie (10-30) sur la base du SOP de chaque bloc de stockage d'énergie individuel dans la pluralité de blocs de stockage d'énergie (10-30) connectés en parallèle, et règle le SOP global calculé sur la valeur limite supérieure pour la puissance ou le courant pour la charge et/ou la décharge d'une unité de conversion de puissance (60). Lorsqu'au moins un commutateur d'une pluralité de commutateurs (S1-S3) est éteint et qu'au moins un bloc (30) de la pluralité de blocs de stockage d'énergie (10-30) est séparé, l'unité de commande (50m) calcule le SOP global des blocs de stockage d'énergie (10, 20) restants sur la base des variations de courant de chacun des blocs de stockage d'énergie (10, 20) restants, et définit la valeur limite supérieure pour la puissance ou le courant circulant vers l'unité de conversion de puissance (60).
(JA) 蓄電システム(1)において、管理部(50m)は、並列接続された複数の蓄電ブロック(10-30)の各単体のSOP(State Of Power)に基づいて複数の蓄電ブロック(10-30)全体のSOPを算出し、算出した全体のSOPを電力変換部(60)の充電および放電の少なくとも一方の電力または電流の上限値に設定する。管理部(50m)は、複数のスイッチ(S1-S3)の少なくとも1つがターンオフして複数の蓄電ブロック(10-30)の少なくとも1つ(30)を解列するとき、残りの蓄電ブロック(10、20)全体のSOPを残りの蓄電ブロック(10、20)の各単体の電流バラツキに基づいて算出し、電力変換部(60)に流す電力または電流の上限値を設定する。
