An Evaluation Method of Distribution Network Scheduling Mode Based on Comprehensive Weight TOPSIS Model

The complexity, perception difficulty and scheduling management difficulty of distribution network are far beyond those of main grid and along with the large amount grid-connection of new energy the selection of dispatching and management mode of distribution network is such a work in a need for research urgently. In allusion to the problem of selecting distribution network dispatching and management mode, a dispatching and management mode evaluation method based on the model of technique for order preference by similarity to ideal solution (abbr. TOPSIS) was proposed to implement the evaluation and analysis on dispatching and management modes. Firstly, the current dispatching management modes and the being planned future intensification mode were summarized, and taking the grid-connected capacity of new energy into account and comprehensively considering high efficiency, coordination, economy and sociality an evaluation index system for distribution network dispatching and management was constructed. Secondly, by use of analytic hierarchy process (abbr. AHP) algorithm and entropy weight method, the subjective and objective weights were obtained and the weighted comprehensive weight was obtained, furthermore, a TOPSIS-based evaluation model was established. Finally, taking a certain actual distribution network located in North China for example, the feasibility of the proposed method was verified.
