Research on a Grid-based Optimal Planning Method for Urban Distribution System
-
Abstract
A rational planning scheme is critical for reliability of system and efficiency of utility. The ideas of planning based on short-term demand are considered to be the main reason of chaos network structure, difficult operation and low maintaining efficiency. In this paper, a grid-based planning method is proposed. Based on the established hierarchical model and division method of grids, the classification standards and constructions demand evaluation indexes are proposed. Therefore, planning, construction, operation, maintenance and marketing can be performed based on girds and the closed-loop optimization of multi-links can be achieved. A engineering practices of distribution system planning in the LH district indicated the correctness of the method proposed in this paper.
