Title:
DC POWER TRANSMISSION SYSTEM AND DC POWER TRANSMISSION METHOD
Document Type and Number:
WIPO Patent Application WO/2024/042595
Kind Code:
A1
Abstract:
The DC power transmission system of an embodiment has one DC transmission line, a transmission-side power converter, a reception-side power converter, an energy consuming device, and a control device. The DC transmission line transmits DC power. The transmission-side power converter converts AC power to DC power, said AC power being supplied by a renewable energy power supply interconnected to the transmission side, and outputs the DC power to the DC transmission line. The reception-side power converter converts the DC power transmitted by the DC transmission line to AC power and supplies the AC power to the reception side. The energy consuming device is connected to a position between an AC power transmission system and the DC transmission line on the transmission side and, when the AC power supplied by the renewable energy power supply results in surplus power in association with power variations that have occurred, consumes the surplus power. The control device controls the operation of the energy consuming device.
