•The interconnection of AC and DC microgrids results in a hybrid AC/DC microgrid.•The control of bidirectional interlink power converters has taken a lot of research attention.•Different interconnection methods and control challenges of AC/DC microgrids are reviewed.•Various control strategies of BILPCs presented in literature are also overviewed. The interconnection of AC and DC microgrids results in a hybrid AC/DC microgrid (HMG). In light of HMGs, the future smart grid implementation will be facilitated. One important aspect in HMGs is the interconnection of AC and DC microgrids and control of bidirectional interlink power converters (BILPCs), which has taken a lot of research attention in the last decade. The BILPCs are the most prevalent method for interconnection of HMGs. Thus, the current study first reviews different interconnection methods and control challenges of AC and DC microgrids in HMGs and then overviews various control strategies of BILPCs presented in literature, all carried out in a comprehensive manner.
