摘 要:基于支路可觀概念,提出了一種在保證系統(tǒng)完全可觀測(cè)的情況下,以布置信息采集點(diǎn)最少為目標(biāo)的信息采集點(diǎn)優(yōu)化布置算法。介紹了支路可觀基本原理,建立了基于支路完全可觀的有源配電網(wǎng)信息采集點(diǎn)優(yōu)化布置模型,對(duì)建立的整數(shù)規(guī)劃模型采用分枝定界法進(jìn)行求解,并分析了有源配電網(wǎng)中DG接入位置不同對(duì)優(yōu)化布置方案的影響。在14節(jié)點(diǎn)和37節(jié)點(diǎn)有源配電網(wǎng)系統(tǒng)中進(jìn)行算例分析,驗(yàn)證了所提算法的正確性。

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
