Abstract

The invention relates to a rural transformer distributed optimization planning method. The method comprises the following steps of (1) establishing a load prediction model considering a novel load access power grid; (2) constructing a distributed distribution transformer network planning model by taking minimum comprehensive cost as a target, and planning a distribution transformer power supply area; and (3) generating a low-voltage line layout scheme by combining the position of the distribution transformer and the power supply range of the distribution transformer and adopting the minimum spanning tree theory of the graph theory. According to the method, reliability and economy of rural power grid power supply are improved, and the method is of great significance for promoting novel rural development and rural power grid reconstruction in the future.

Description

Technical field[0001]The invention relates to the technical field of transformer distributed optimization, in particular to a rural transformer distributed optimization planning method considering the interconnection of a new type of load and a low-voltage side.Background technique[0002]In recent years, the new load represented by electric heating, that is, the proportion of electric energy substitute load has been increasing, and the momentum of development has been rapid. The development of new types of loads is not limited to cities. China's vast rural areas have also attracted new types of loads. However, unlike urban power grids, due to the obvious seasonal characteristics of farmland irrigation and electric heating loads, rural power grids are not conducive to improving the utilization of related equipment after grid-connected operation, so the power supply economy will decline. Therefore, using the flexibility of distribution operation, the new load and the agricultural load ...
