论文摘要
随着分布式生成到分销网络的增殖，考虑调度问题中的故障电流的需求变得越来越相关。本文介绍了一种将故障电流限制添加到最佳功率流中的方法，以减少故障电流，同时最大程度地减少发电成本。最佳功率流问题被提出为单个优化问题，子网络代表感兴趣的故障。有一个单一的优化问题可以使决策变量在最佳功率流和故障电流研究中耦合，而无需迭代可能的解决方案。所提出的方法适用于不平衡的分销网络，包括那些带有引入相移的变压器的方法。
With the proliferation of distributed generation into distribution networks, the need to consider fault currents in the dispatch problem becomes increasingly relevant. This paper introduces a method for adding fault current constraints into optimal power flow in order to reduce fault currents while minimizing generation cost. The optimal power flow problem is formulated as a single optimization problem with sub-networks representing the faults of interest. Having a single optimization problem allows the decision variables to be coupled across the optimal power flow and the fault current studies without having to iterate over possible solutions. The proposed method is applicable to unbalanced distribution networks, including those with transformers that introduce phase-shifts.
