灵活的需求侧能源和备用采购有可能改善电网的整体运行。然而，正如以前的研究所指出的那样，这种灵活性可能会导致配电网的拥塞。本文改进了传统的配电地点边际电价（DLMP）方法，同时将无拥堵能源和配电网中建筑物的备用供应结合起来。首先，强大的dayahead（DA）DLMP计算占未建模的动态柔性负载。其次，使用对偶分解，聚合器和配电系统运营商（DSO）之间的数据共享要求最小化。第三，提出了一种基于灵敏度的实时（RT）调整方法，以消除DA鲁棒DLMP的保守性。案例研究是在一个基准分布系统上进行的。数值结果表明，该方法有效地处理负载的不确定性和数据共享的要求，提高了传统的DMLP方法的实用性。
Flexible demand side energy and reserve procurement has the potential to improve the overall operation of the grid. However, as argued in previous studies, this flexibility might cause congestion in distribution grids. In this paper, we improve the conventional distribution locational marginal price (DLMP) method, while integrating congestion free energy and reserve provision from buildings in distribution grids. First, robust dayahead (DA) DLMPs are calculated to account for unmodelled dynamics of flexible loads. Second, using dual decomposition, the data sharing requirements between the aggregator and the distribution system operator (DSO) are minimized. Third, a sensitivity-based real-time (RT) adjustment method is presented to remove conservatism of DA robust DLMPs. Case studies are performed on a benchmark distribution system. The numerical results show that the proposed technique efficiently handles load uncertainties and data sharing requirements, improving the practicality of the conventional DMLP method.
