In　order　to　solve　the　problem　of　excess　power　consuming　of　the　regional　PV　system,　a　novel　environmental　adaptive　PV　system　control　strategy　is　proposed　in　this　paper.　The　PV　array　uses　a　distributed　connection　structure　with　distributed　pre-optimizers.　Based　on　the　construction　structure　and　a　proposed　environmental　adaptive　algorithm,　the　global　maximum　power　point　tracking　of　the　PV　array　under　different　environment　conditions　can　be　realized.　By　utilizing　a　group　management　based　PV　control　strategy,　the　PV　arrays　in　the　PV　system　can　be　divided　into　several　groups　according　to　different　light　intensity,　and　the　output　power　of　the　PV　system　can　be　control　and　managed　by　group.　The　theoretical　and　simulation　analysis　proves　that　the　control　strategy　proposed　in　this　paper　can　not　only　realize　the　GMPPT　of　the　PV　array　with　or　without　shading,　but　also　can　manage　the　regional　PV　system　in　groups　according　to　the　light　intensity.　By　implementing　the　proposed　strategy,　the　output　power　of　the　PV　system　can　quickly　follow　the　power　demand　of　the　distribution　network,　and　achieve　the　flexible　consuming　of　regional　excess　power　output　of　the　PV　system.　©　2019　IEEE.
