摘 要:基于支路可观概念,提出了一种在保证系统完全可观测的情况下,以布置信息采集点最少为目标的信息采集点优化布置算法。介绍了支路可观基本原理,建立了基于支路完全可观的有源配电网信息采集点优化布置模型,对建立的整数规划模型采用分枝定界法进行求解,并分析了有源配电网中DG接入位置不同对优化布置方案的影响。在14节点和37节点有源配电网系统中进行算例分析,验证了所提算法的正确性。

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
