Abstract

Abstract: Ultra high voltage direct current (UHVDC) is characterized by fast and flexible control, thus has been widely adopted to implement effective power control in power systems. It is of great significance to investigate the capability of UHVDC in power system risk defense. The potential risk of power system operation under the condition of weak AC and strong DC is analyzed, which is a typical engineering problem in China. Based on the analysis, the control strategies are proposed that involve UHVDC in the three-defense-line control at the receiving end of power systems, so as to counter the risk of DC blocking. The proposed control strategies include:pre-control of active power of UHVDC, coordinated control of UHVDC and load shedding, coordinated control of UHVDC and under-frequency load shedding in the occurrence of the breaking of weak AC connection. The validity of the proposed methods is verified by simulation.

Key words: strong DC and weak AC, DC blocking, three defense line, pre-control measures of active power of HVDC, emergency modulation of HVDC, coordinated control
