Load-Flow Conditions for HVDC Transmission in Synchronous Networks

摘要

The basic purpose for HVDC (high-voltage direct current) transmission is to transmit a determined value of electrical power from one electrical node to another. If there is an AC system in parallel to an HVDC trans- mission, the load flow via this parallel AC system can be controlled directly. Since HVDC systems offer pos- sibilities to perform fast load-flow control, they can also be used for improving stability.
