【摘要】：有效评估电网支路和节点的重要度,对于构建电网的核心骨干网架具有重要的指导作用。文中将模糊理论引入风险评估中,采用模糊数描述发电机和负荷的不确定性,提出了一种新的支路重要性评估方法,并进一步结合节点接近度和节点关键度得出节点的重要度。在此基础上,建立了综合考虑支路和节点重要度的核心骨干网架构建模型,并采用离散粒子群算法进行核心骨干网架搜索。仿真算例表明,该方法能有效解决网架中的支路和节点重要性评估问题,搜索得到的核心骨干网架方案在保障重要负荷正常供电的同时,有选择性地保留重要度较大的元件并满足节点数和支路数最少。
[Abstract]:Effective evaluation of the importance of branches and nodes plays an important role in guiding the construction of the core backbone grid. In this paper, fuzzy theory is introduced into risk assessment, fuzzy number is used to describe the uncertainty of generator and load, a new branch importance evaluation method is proposed, and the importance degree of node is obtained by combining node proximity and node criticality. On this basis, the core backbone network structure model considering the branch and node importance is established, and the discrete particle swarm optimization algorithm is used to search the core backbone network. Simulation examples show that this method can effectively solve the problem of importance evaluation of branches and nodes in the grid, and the core backbone network scheme obtained by searching can guarantee the normal power supply of important loads at the same time. Selectively retain the more important components and satisfy the minimum number of nodes and branches.
