论文摘要
分销网络中的分布式能源（DER）可以作为传输级操作的虚拟发电厂（VPP）汇总。这种协调的一个关键挑战是，在公共耦合点，AC可行的功率传递区域的复杂性。为了克服这一挑战，本文为此类地区开发了一种表征方法。所提出的方法构建了线性约束，以对AC可行的功率传递区域进行陈列。为了确保AC的可行性，这些约束中的参数是通过将Brouwer固定点定理应用于非线性分流方程的二阶Taylor扩展来确定的。基于以我们的方法为特征的功率传输区，通过Big-M线性化制定并求解了带有VPP参与的传输级操作问题。通过IEEE 33-BUS和IEEE 136-BUS测试系统中的数值实验来验证所提出的方法。
Distributed energy resources (DERs) in distribution networks can be aggregated as a virtual power plant (VPP) for transmission-level operations. A critical challenge for such coordination is the complexity of the AC-feasible power transfer region between a VPP and the transmission system at their point of common coupling. To overcome this challenge, this paper develops a characterization method for such regions. The proposed method constructs linear constraints to inner-approximate the AC-feasible power transfer regions. To guarantee AC-feasibility, the parameters in these constraints are determined by applying the Brouwer fixed point theorem to the second-order Taylor expansion of the nonlinear Dist-Flow equations. Based on the power transfer regions characterized with our method, a transmission-level operation problem with VPP participation is formulated and solved through big-M linearization. The proposed methods are verified by numerical experiments in the IEEE 33-bus and IEEE 136-bus test systems.
