MicrogridOperationModes: Microgridscanoperateinvariousmodes,includingislandedmode,grid-connectedmode,andhybridmode.Islandedmodereferstothecompletedisconnectionofthemicrogridfromtheutilitygrid,relyingsolelyonitsownresourcesandgenerationcapabilities.Grid-connectedmodeallowsthemicrogridtoexchangeelectricitywiththeutilitygridbasedondemandandsupplyconditions.Hybridmodecombinesbothislandedandgrid-connectedmodestoprovidegreaterflexibilityandresilience.Eachoperationmodehasuniqueeconomicimplications,whichwewillexploreinthisanalysis.
