Power　system　scheduling　of　renewable　energy　sources　has　been　studied　extensively　due　to　the　severe　increase　in　pollution　caused　by　conventional　energy　sources.　In　this　study,　a　multi-objective　scheduling　model　of　a　hybrid　microgrid　is　proposed　to　minimize　the　cost　of　hybrid　microgrids　and　maximize　the　power　supply　reliability.　The　main　power　generation　units　such　as　the　wind　turbines,　photovoltaic　(PV)　cells,　and　battery　banks　are　used　in　this　hybrid　microgrid.　In　this　study,　the　optimal　sizing　of　PV　panels　and　battery　banks　are　obtained　using　multi-objective　particle　swarm　optimization　(MOPSO)　for　the　proposed　multi-objective　scheduling　model.　The　lifetime　of　battery　banks　is　considered　in　the　energy　storage　system　(ESS)　model.　Finally,　the　practicality　of　the　scheduling　model　proposed　in　this　study　is　verified　by　four　examples.
