摘要:

半定规划(SDP)为最优潮流问题提供了严格的下界。然而,解决大规模SDP问题需要利用稀疏性。在本文中,我们实验几个团分解算法,导致不同的重新制定,我们表明,分辨率是高度敏感的团分解过程。我们的主要贡献是证明,最小化弦扩展中的附加边的数量并不总是合适的,以获得一个良好的团分解。

英文摘要:

Semidefinite Programming (SDP) provides tight lower bounds for Optimal Power Flow problems. However, solving large-scale SDP problems requires exploiting sparsity. In this paper, we experiment several clique decomposition algorithms that lead to different reformulations and we show that the resolution is highly sensitive to the clique decomposition procedure. Our main contribution is to demonstrate that minimizing the number of additional edges in the chordal extension is not always appropriate to get a good clique decomposition.
