“…This systematic literature review (SLR) examines articles relevant to HL2, in which the reliability of composite generation and transmission systems is studied. The literature has contributed to reliability studies on composite power systems by proposing new models [22,23], improving computation efficiency [19,[24][25][26], improving accuracy [4,27,28], optimization [15,[29][30][31], and differentiation of alternatives [32,33]. The reliability of composite generation and transmission systems plays a crucial role in system evaluation.…”
