Abstract：In China，the ascendancy of new energy sources such as photovoltaic and wind power，alongside the proliferation of DC loads within the power system，has propelled hybrid AC/DC distribution networks to the

forefront of power distribution system evolution. However，the extant assessment framework for distribution

network configurations is inadequate for hybrid AC/DC systems，and prevailing planning strategies overlook the

interconnectedness of multi-stage network evolution. Consequently，an evolutionary planning methodology for AC/

DC hybrid distribution networks with an emphasis on economic considerations was extensively studied. Initially，

addressing the incongruity of the conventional distribution network assessment system with hybrid setups，an

enhanced grey clustering- criteria importance through intercriteria correlation（CRITIC）amalgamation technique

was advocated. Subsequently，leveraging this framework，a multi-stage evolution model anchored in the sequential second-order cone programming（SSOCP）paradigm was developed to refine the multi-stage evolutionary trajectory of hybrid distribution networks. Ultimately，through illustrative examples，the efficacy and primacy of this approach were substantiated.
