Abstract
This paper investigates the influence of a high voltage direct current (HVDC) overlay grid on the transient voltage and rotor angle stability with respect to HVDC converter fault ride-through behavior. For this purpose, the studied meshed hybrid AC/DC transmission grid is established in MATLAB/Simulink with user defined dynamic models of voltage-source converters (VSC) considering fault ride-through requirements of the German Technical Connection Rules for extra high-voltage (VDE-AR-N 4130). The voltage profile during three-phase short-circuit faults as well as bus voltage relative entropy after fault-clearing as stability indices are analyzed. The influence of k-factor and power system stabilisers on transient stability is also investigated.
