摘要
提出了一种基于二阶网络模型的最优潮流(Optimal Power Flow,OPF)模型;基于二阶网络模型的OPF不仅可以克服直流OPF的缺点,即准确地描述出线路上的有功损耗,且可以转化成非线性的凸规划,从而保证快速收敛到全局最优解。基于二阶网络模型的OPF问题,采用鲁棒性好、收敛速度快的预测校正内点法求解。为了显示模型的合理性和相应算法的有效性,采用IEEE30节点、IEEE118节点和IEEE300节点3个测试系统进行数值仿真。
This paper presents a second-order network model for solving the optimal power flow(OPF) problem,the OPF problem with the second-order network model not only can achieve an accurate representation of the line losses which is the main obstacle of OPF,but also can be transformed into the nonlinear convex programming so that the fast convergence to the global optimal can be guaranteed.Due to the robustness and fast convergence performance,the predictor-corrector interior point method is applied to solve the convex programming based OPF problem.The numerical results on IEEE 30 bus,IEEE 118 bus,and IEEE 300 bus cases indicate that the mathematical model is reasonable and the algorithm is efficient.
