A　novel　analytical　approach　to　reliability　evaluation　of　voltage-source　converter-based　multi-terminal　direct　current　(VSC-MTDC)　integrated　offshore　wind　plants　is　presented　in　this　study.　To　treat　the　multi-terminal　grid　precisely　and　efficiently,　the　approach　combines　the　state　evaluation　method　and　network　flow　method.　A　DC　line　equivalent　component　is　also　proposed　to　consider　the　operation　modes,　failure　clean　measures　as　well　as　interactions　between　different　DC　lines　of　VSC-MTDC.　Employing　this　approach,　the　authors　can　obtain　both　frequency　and　probability　indexes　of　reliability.　The　usefulness　and　effectiveness　of　the　proposed　method　are　verified　by　case　studies.　The　comparison　between　three　popular　schemes　is　also　carried　out.
