Increasing use of power electronic-based (PE-based) units has intensified the importance of the security scope of power systems. So far, the conventional security assessment approaches are used in the modern PE-based power system. It is not sufficient for the analysis of the system security. In this paper, a new scope of the PE-based power system security is proposed. To do so, the security assessment of PE-based units are involved in the general range of the system security assessment. More specifically, the transient stability and security of the grid-connected voltage source converters (VSCs) are studied in the scope of dynamic security of the PE-based power systems. Obtained results show that the new security scope gives a valuable viewpoint of the system security assessment in comparison with the conventional security schemes.
