Research on single-dual power supply scheme based on Prim greedy algorithm planning and reliability analysis

Distribution security and stability are very important for customers' daily electricity consumption. In this paper, the method of planning the main supply line of 10kV distribution network with 100 customer transformers and 2 power substations by using one-dimensional linear regression is presented for single-supply and dual-supply scenarios, and the method of planning the branch lines of distribution network with 50 customer transformers by using P rim’s greedy algorithm is introduced. The main power supply line of two power sources is connected with a liaison line for a given total investment or a given lower reliability limit, and the main power supply line structure in the form of a double-loop network can significantly improve the reliability of customer transformers.
