To increase the scientificity of distribution network planning, an innovative problem-oriented automatic distribution grid planning method is proposed. Firstly, the power flow and feeder connection mode identification results are used to identify the typical network problems in the distribution grid to be planned. Then, strategies to automatically generate the solutions to the above problems are designed by quantifying both technical limitations such as line and transformer capacities limits, and practical engineering constraints such as feeder-connected transformer capacity limits, power supply path length limits, etc. Taking a mid-voltage line-overloading problem and two different types of the feeder reconstruction problems as examples, the proposed method is finally verified and explained in detail.
