Title:
POWER STORAGE DEVICE AND POWER SYSTEM STABILIZATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/102025
Kind Code:
A1
Abstract:
A power storage device (13) of one embodiment is provided with: a power storage bank (ESB) comprising a plurality of power storage elements (30) connected to one another; and one or more first cells (BSM). The power storage bank (ESB) and the one or more first cells (BSM) are connected in series to one another. Each of the first cells comprises an input/output node pair (24p, 24n), a bridge circuit (25) comprising at least two semiconductor switching elements (21p, 21n), and a power storage element (22) connected to the input/output node pair (24p, 24n) via the bridge circuit (25). The power storage capacity of the power storage element (22) of each of the first cells (BSM) is smaller than the power storage capacity of the power storage bank (ESB).
