The article presents a comparative analysis of phasor RMS and EMT models for grid-forming converters. The specific aspects related to modelling and implementation in Simscape Electrical of MATLAB/Simulink are discussed in detail for both time-domains. The comparison between the implementations is performed taking into examination three representative and widely studied grid-forming schemes: the virtual synchronous machine, the power-synchronization control and the feedforward angle control. For the analysis, different power system dynamics are emulated, and different types of transient phenomena are applied in the simulation models. The considered events include frequency transients, phase jumps and short-circuit faults. The comparative analysis suggests specific indications regarding limitations and suitability of phasor RMS and EMT models for grid-forming converters, contributing to the definition of possible guidelines for a proper selection of the modelling domain

Abstract
The article presents a comparative analysis of phasor RMS and EMT models for grid-forming converters. The specific aspects related to modelling and implementation in Simscape Electrical of MATLAB/Simulink are discussed in detail for both time-domains. The comparison between the implementations is performed taking into examination three representative and widely studied grid-forming schemes: the virtual synchronous machine, the power-synchronization control and the feedforward angle control. For the analysis, different power system dynamics are emulated, and different types of transient phenomena are applied in the simulation models. The considered events include frequency transients, phase jumps and short-circuit faults. The comparative analysis suggests specific indications regarding limitations and suitability of phasor RMS and EMT models for grid-forming converters, contributing to the definition of possible guidelines for a proper selection of the modelling domainFile | Dimensione | Formato | |
