摘要: 针对传统解列断面算法复杂度高的问题,提出一种基于改进LFM算法的解列断面搜索方式。首先,基于节点间电气联系和能量转移分布熵完成电网加权复杂网络建模;其次,基于主动解列断面约束条件,对LFM算法做适应性改良;最后,通过改进LFM算法得到解列断面,并在IEEE39节点系统中验证了算法有效性。仿真结果表明,改进LFM算法可充分考虑传统解列断面的约束条件,在算法具有较低复杂度的同时对系统运行状态更强的适应性。Abstract: A splitting section search method based on modified LFM algorithm is proposed to solve the complexity of traditional splitting section algorithm. Firstly,weighted complex network is modeled by the electrical connection between nodes and energy transfer distribution entropy;Secondly,LFM algorithm based on the constraint of automatic splitting surface is improved;Finally,the automatic splitting surface is obtained by the modified LFM algorithm,and verifies the effectiveness of the algorithm in the IEEE39-node system.The simulation results show that the improved LFM algorithm can fully consider the constraint conditions of the traditional splitting,and the algorithm has lower complexity and is more adaptable to system operating state.
