论文摘要
AC功率流程方程的线性近似对于大规模最佳功率流（OPF）问题的计算效率具有重要意义。换句话说，获得的解决方案的可行性对于OPF的实际用例至关重要。但是，大多数研究都集中在近似误差上，并且缺乏全面研究功率流的不同线性近似值的AC可行性。本文讨论了OPF问题中主动功率的广泛线性近似值的优点。关于四个标准，讨论了线性化模型的优势和缺点。线性近似，最佳，可行性和计算时间的精度。每种方法都在五个不同的系统上进行测试。
Linear approximations of the AC power flow equations are of great significance for the computational efficiency of large-scale optimal power flow (OPF) problems. Put differently, the feasibility of the obtained solution is essential for practical use cases of OPF. However, most studies focus on approximation error and come short of comprehensively studying the AC feasibility of different linear approximations of power flow. This paper discusses the merits of widely-used linear approximations of active power in OPF problems. The advantages and disadvantages of the linearized models are discussed with respect to four criteria; accuracy of the linear approximation, optimality, feasibility, and computation time. Each method is tested on five different systems.
