Document Type and Number:
WIPO Patent Application WO/2020/211307
Kind Code:
A1
Abstract:
Disclosed are a building full-direct-current power supply and electricity storage system and control method. The system comprises a renewable energy power generation device (2), a municipal power grid system (4), a first direct-current/direct-current conversion device (3), an alternating-current/direct-current conversion device (5), a first voltage direct-current bus (1), a first energy storage device (6) and a first charging and discharging conversion device, wherein the first direct-current/direct-current conversion device (3) is used for converting a direct-current voltage generated by the renewable energy power generation device (2) into a voltage of the first voltage direct-current bus; the alternating-current/direct-current conversion device (5) is used for converting an alternating current generated by the municipal power grid system (4) into a direct current; the first charging and discharging conversion device is used for controlling the charging and discharging conversion of the first energy storage device (6); and the first voltage direct-current bus (1) is connected to first electricity utilization equipment (9) and is used for supplying power to the first electricity utilization equipment (9). The building full-direct-current power supply and electricity storage system and control method have the advantages of improving the power supply and power distribution efficiency and fully consuming local renewable energy.
