Abstract

The computational process of both time-domain and phasor-domain algorithms is evaluated in this work. The following methods are used: circuit-based time-domain (TD), dynamic phasors (DP), three-phase phasor-domain (3pPD), and classic positive sequence phasor-domain (PD). The IEEE-118 benchmark is used to test all solution approaches implemented on the same computational platform. Furthermore, the advantages and differences in modeling methodologies are examined for the IEEE-118 benchmark. The experiments demonstrate important new facts on phasor-domain methods and, more specifically, on dynamic-phasors compared to TD algorithms.
