摘要：

This paper proposes a voltage regulation of synchronous condensers and switching capacitors in the power grids with a ultra-high voltage (UHV) DC/AC system. The control is able to regulate the system voltages in permitted range, reduce the times of switching capacitors, and improve the system dynamic voltage stability. Firstly, the influences of the UHV DC/AC system, switching capacitors, and synchronous condensers on system dynamic voltage stability are estimated. And then, the sensitivity of bus voltages and reactive power is used to select the switching capacitors. A voltage control model with synchronous condensers and switching capacitors is established. Finally, an improved interior point method is applied to solve the voltage control model. An actual power grid with a UHV DC/AC system is used to validate the effectiveness of the proposed scheme.
