Abstract: Based on branch-observed concept, this paper proposed a kind of optimal placement algorithm to minimize information collecting nodes under the conditions making the active distribution network completely observable. Introduction was made to the basic branch-observed principle. This paper established the optimal placement model based on the completely branch-observed active distribution network for information collecting nodes, and the branch and bound method is used to solve the integer programming problem. In addition, the influence of the optimal placement has been discussed when the distributed generation (DG) is accessed to the distribution network in different locations. The proposed algorithm is tested with 14-bus and 37-bus active distribution network. The correctness of the algorithm has been verified.
Key words: active distribution network; information collecting nodes; branch-observation; optimal placement; branch and bound method
