Carrying　out　green　energy　transformation,　implementing　clean　energy　power　replacement　and　supply,　and　developing　a　new　power　system　are　some　primary　driving　forces　needed　to　fulfill　China＇s　carbon-peak　and　carbon-neutral　strategic　goals.　The　construction　of　new　power　systems　in　China＇s　provinces　and　cities　is　developing　rapidly,　and　the　lack　of　a　typical　model　promotes　the　application.　The　new　power　system　path　design　should　be　based　on　the　actual　development　of　the　power　grid　in　different　regions,　energy　use　characteristics,　and　other　actual　needs　to　carry　out　the　differentiated　path　design.　In　this　context,　this　study　analyzes　the　characteristics　of　the　new　domestic　power　system　based　on　the　policy　background　of　the　new　domestic　power　system,　constructs　a　new　model　for　power　system　development　stage　identification,　and　proposes　the　overall　design　of　the　new　power　system　development　path　from　the　power　supply,　transmission　and　distribution,　and　load　sides.　It　also　uses　the　Hebei　South　Network　as　an　example　to　explore　the　development　stage　of　the　Hebei　South　Grid　based　on　actual　development　needs.　Finally,　this　study　designs　a　novel　power　system　development　path　for　the　entire　supply　and　demand　chain　for　the　Hebei　South　Grid　to　propose　ideas　for　constructing　a　new　power　system　in　China　and　to　help　green　energy　transformation.　©　2023
