摘要：
With the increasing integration of power electronic devices into the power system, the strength of the power grid is relatively weakened, and the system faces higher risk of small-signal instability. Synchronous condensers can provide voltage support for the power system fed by large-scale power electronic devices, which reduces the risk of the system instability. However, the quantitative research on the effect of synchronous condensers on system stability improvement is not mature, and the siting planning method is inadequate. To this end, the dynamic model of multi-infeed system integrated with synchronous condensers is first established. Then, the mechanism that synchronous condensers improve the strength and the stability margin of the system is theoretically deduced. Finally, the optimal siting method of synchronous condensers is studied from the perspective of improving the stability margin of the system. The effectiveness of the proposed method is verified through simulations on a 2-area 4-machine system and a 39-bus system. © 2022 Automation of Electric Power Systems Press.
