论文摘要
这是在二线战略招标或投资模型的较低级别中使用的有关交流最佳功率流的研究的第二部分。作为合适的上层问题的一个例子，我们观察到了储能的战略招标，并提出了基于平滑技术的新型制定。在介绍了我们工作的想法和范围，以及模型本身和伴侣论文中的解决方案算法（第I部分）之后，本文介绍了许多现有的解决方案技术，并基于平滑互补条件而提出的解决方案技术。与不同尺寸和不同OPF模型的多个传输网络相比，所提出的算法和平滑技术的优越性在精度和计算障碍性方面得到了证明。结果表明，所提出的方法在两个指标中的表现都大大优于所有其他选项。这在准确度的指标中尤其明显，而在9个网络网络上总计422个优化中，最大的AC OPF误差为0.023％，在我们的算法的第二次迭代中进一步降低至3.3e-4％。
This is a second part of the research on AC optimal power flow being used in the lower level of the bilevel strategic bidding or investment models. As an example of a suitable upper-level problem, we observe a strategic bidding of energy storage and propose a novel formulation based on the smoothing technique. After presenting the idea and scope of our work, as well as the model itself and the solution algorithm in the companion paper (Part I), this paper presents a number of existing solution techniques and the proposed one based on smoothing the complementary conditions. The superiority of the proposed algorithm and smoothing techniques is demonstrated in terms of accuracy and computational tractability over multiple transmission networks of different sizes and different OPF models. The results indicate that the proposed approach outperforms all other options in both metrics by a significant margin. This is especially noticeable in the metric of accuracy where out of total 422 optimizations over 9 meshed networks the greatest AC OPF error is 0.023% that is further reduced to 3.3e-4% in the second iteration of our algorithm.
