Abstract

High voltage direct current (HVDC) links are increasingly applied for system interconnections. This is mainly due to the asynchronous system operation and fast controllability of power flow in a DC link. While HVDC links are primarily used for point-to-point transmission of power, multi-terminal operation will increase the flexibility and scope of their application. Special problems arise in the operation of DC links when the AC system in which DC link is embedded is weak. One such major operational problem is voltage instability at the converter bus. A general formulation for voltage stability calculation applicable for multi-terminal systems is presented. The proposed technique is applied for the evaluation of controllers at the voltage setting terminal utilizing the example of a four terminal system
