In order to adapt to the development needs of new load access to rural power grids, solve the problem of low utilization efficiency of related equipment, and take into account economy and power supply reliability, this paper proposes a distributed optimization planning method for rural transformers considering new load and low-voltage side interconnection. First, this paper establishs a load forecasting model that considers new types of loads such as electric heating; secondly, it builds a distributed distribution transformer network planning model with the goal of minimizing overall costs, and applys the Voronoi method to plan distribution transformers; finally, it combines the location of the distribution transformer and its power supply Scope, using the minimum spanning tree theory of graph theory to generate low-voltage line layout schemes. This paper is based on Matlab R2014a simulation platform to plan the distribution of typical power supply areas. The results of calculation examples verify the feasibility of this method, which can improve the economy and reliability of power supply by reducing losses.
