Abstract

This paper proposes the VSC-HVDC application to enhance and increase long-term voltage stability. A suitable controlling technique for VSC-HVDC is proposed in the paper. The goal is to reach the best possibilities from long-term voltage stability perspective with respect to system configuration and also the VSC-HVDC capability curve. To show the capability of the proposed control methodology, two long-term voltage instability scenarios are considered. For the first scenario, VSC-HVDC can lead to a stable condition with its initial active-reactive power set points. In the second voltage instability scenario which is more severe, the proper power flow change in the system using VSC-HVDC is needed to avoid the voltage collapse. VSC-HVDC is ever to effectively compete with classical HVDC, protective devices must be implemented in the system. Presently classic protection devices are widely in use for protection in HVDC Systems.
