Urban Distribution Network Planning Considering Block Loads

Urban distribution network planning is an important distribution network planning problem which needs to consider the street layout and block loads. Traditionally, the load within a block area is taken as a single load point. In this paper, a new urban distribution network planning model is proposed. The location and sizing of substations, and the routing and capacity of distribution power lines are simultaneously optimized. The load in a block is distributed to the surrounding segments, and then distributed to the adjacent junctions of the segments. The model belongs to a mixed integer linear programming problem and it can be solved by state-of-art commercial solver. The validity and effectiveness of the proposed model are illustrated by case studies.
