Abstract

This paper first discusses the ranking of electric power system dynamic behavior in a dynamic security assessment system. This ranking is calculated by combining seven performance indices based on fuzzy logic. These security indices are applied to monitor the security level of the power system. Secondly, the paper focuses on the application of voltage source converter based high voltage direct current (VSC HVDC) transmission for improving this ranking. Due to the advantages that VSC HVDC has, such as fast and decoupled active and reactive power control, the power system stability can receive many benefits after a disturbance such as damping the oscillation of the load angle of the generators as well as voltage support. The validity of the technique is tested on an exemplary 11-bus system using PSS^®NETOMAC software simulation. This procedure can be applied to both off-line as well as on-line applications.
