| 摘 要： | 利用L1范数把电力系统潮流方程的求解转化为对一个新的非线性规划模型L1LF的求解.在基于原问题的扰动Karush-Kuhn-Tucker(KKT)条件基础上,导出了求解L1LF模型的内点算法公式.仿真结果显示,L1LF模型结构简洁、直观,编程应用方便.新算法计算结果正确,收敛性好.和常规潮流算法相比,新模型和新算法有效解决了病态系统潮流计算发散的问题,为给定条件下的潮流问题是否有解提供了一个新的判断途径.

| Abstract: | Based on L1 norm,this paper presents a novel nonlinear programming module L1LF including of power flow equations.Using the perturbed Karush-Kuhn-Tucker(KKT) conditions of the primary problem,we derive an interior point correct formulation for solving the general load flow problem.Proposed module and algorithm possess simplifying structure,excellent convergence property and can be implement or program easily.The results of experiments are correct,accurate and reliable.At same time,the proposed module and algorithm solve the illconditioned system problem effectively and successfully.It is also a new way to judge whether the general load flow has not feasible solutions. |
