New　energy　such　as　photovoltaic,　wind,　fuel　cells　has　many　advantages,　but　the　distributed　power　generation　system　(DPGS)　supplied　by　single　kind　of　new　energy　cannot　provide　sustained,　stable　and　continuous　power　because　of　the　instability　and　non-continuity　of　new　energy.　In　order　to　improve　the　stability　and　flexibility　of　the　power　supply　system　and　realize　the　prior　or　full　use　of　new　energy,　the　multi-energy　DPGS　is　adopted.　The　two-stage　single-input　DC-DC　converter　mode,　two-stage　multi-input　DC-DC　converter　mode,　quasi-single-stage　multi-input　DC-DC　converter　mode　multi-energy　DPGS　are　systematically　presented,　their　circuit　structures,　circuit　topology　examples,　energy　management　control　strategies(EMCSs),　characteristics　and　design　examples　are　given　in　this　paper,　which　will　provide　a　guidance　to　the　research　and　application　of　the　multi-energy　DPGS.
