- Abstract
When faults such as blocking and commutation failure occur in a high-voltage direct current (HVDC) transmission system, they can cause transient voltage fluctuations near the sending-side converter station and lead to the disconnection with power grid. Firstly, the operating principles, response characteristics, and key parameter influences of the grid-forming energy storage open-loop control strategy are analyzed. Then, the reactive response characteristics of the synchronous condenser are analyzed, and a comparison is made between the grid-forming energy storage reactive power control model and the excitation regulation control model. Finally, a semi-physical simulation system is established, including EHVDC, photovoltaics, synchronous condenser, and grid-forming energy storage, to conduct comparative experiments on the effect of suppressing AC transient overvoltage under DC commutation failure. The results indicate that grid-forming energy storage and distributed synchronous condenser with the same capacity can achieve similar effects in terms of reactive transient response speed and the ability to suppress AC transient overvoltage.
