Optimization Study of Distribution Network Conductor Selection Under Large-Scale Rooftop Photovoltaic Access

Aiming at the traditional 10kV distribution line sizing planning guideline which is difficult to adapt to the problem of large-scale distributed PV access, a new type of 10kV distribution line sizing planning model considering the influence of rooftop PV output size, growth rate and continuous load growth is proposed. At the same time, different load growth rate, different PV growth rate, different PV capacity, different planning years and different load nature of the distribution network lines for example simulation analysis, to get a different situation of distributed PV power containing distribution network conductor selection guidelines. The deficiency of the current distribution network conductor configuration scheme is improved, and new ideas and solutions are provided for the economy of distributed PV distribution network operation.
