摘要
针对考虑不平衡负荷和发电的最优潮流问题，对单相配电系统的二阶锥松弛和多相配电系统的半定松弛进行了数值比较。为此，IEEE 37总线测试馈线采用四种不同的配电线路模型，用于不同的馈线段，并在选定的节点上安装光伏逆变器。Matlab Software for Disciplined Convex Programming (CVX)生成的结果表明，对于多相算法，使用四种线模型找到的解几乎相同，但使用单相算法的损失可能更大。
Comparison of the distribution optimal power flow relaxations for unbalanced loads and generations
This paper presents a numerical comparison between the second order cone relaxation for single-phase distribution systems and the semidefinite relaxation for the multiphase distribution systems for the optimal power flow problem considering unbalanced load and generation. Towards this end, the IEEE 37-bus test feeder is adapted using four different distribution line models for the various feeder segments and by populating selected nodes with photovoltaic inverters. Results generated by Matlab Software for Disciplined Convex Programming (CVX) suggest that solutions found using the four line models are almost identical for the multiphase algorithm, but losses may be larger using the single-phase algorithm.
