  This paper reviews Voltage-Source Converters (VSCs) EMT and Phasor models
currently used to simulate converter-interfaced generation (CIG) and renewable
energy resources integration to power systems. Several modelling guidelines and
suitability analyses were provided based on a comprehensive comparative study
among the models. Various studies were performed in a small system and a large
system, modelled in Simulink. We address a gap related to the suitability of
CIGs phasor models in studies where the boundary between electromagnetic and
electromechanical transients overlap. An insightful analysis of the adequate
simulation time step for each model and study is also provided, along with
several simulation guidelines.
