Planning Method of Feeder Automation of Distribution Network in Mountain Area Considering Distributed Generation

摘要

The existing planning method of feeder automation (FA) of distribution network in mountain area doesn't consider the access of distributed generation (DG), and has no differentiated guidance on the actual line situation. Aiming at the status quo, a new planning method of FA of 10 kV distribution network in mountain area considering DG is proposed in this paper, based on the analysis of the main construction mode of FA and the influence of the access of DG. Aiming at the minimum of total annual cost of automatic configuration, the planning model of FA is established. With the cluster results of actual line, the optimal solution of the model in different situations is obtained, including the types of configuration scheme and the numbers of switches. Further, the recommendation table of automation planning is formed, which is Instructive. The example shows the method is superior in economy satisfying the reliability index.
