Abstract: In order to achieve goals of the carbon peaking and carbon neutrality, the percentages of distributed PVs and EVs are increasing in city distribution networks. The hydrogen storage techniques are integrated in source, network and load sides. The city networks are faced with the changes of both network framework and operation modes, which brings great challenges for planning. In order to accommodate the PV and EV safely and economically, this paper summarizes and compares the existing distribution network planning works from characteristic analysis, collaborative strategies, model construction and uncertainty treatments of PV-EV-hydrogen. Three key problems are summarized including the flexibility evaluation of PV-EV-hydrogen, multi-dimension multi-timescale uncertainty treatment, long period huge scale joint planning model construction and resolution. Finally, the prospect for future city distribution network is given, which illustrates the game between power system and users, the risk constrained network planning and planning under high penetration of PV-EV-hydrogen.
