摘要:

构建抗灾型骨干网架并对其进行差异化加固,可以保障极端灾害下电网安全运行和重要负荷供电。在此背景下,提出一种计及多阶段抗灾性能的骨干网架多目标优化模型。该模型定量评估了电网中节点和线路的拓扑和运行重要度,并提出基于核主元分析的综合评估方法。在满足投资限制的基础上,以最大化网架生存性、抗毁性和系统可恢复性为目标对抗灾型骨干网架进行优化。然后,采用嵌入图论修复策略和档案学习策略的改进全面学习粒子群优化算法求解优化模型,以扩大可行解空间。最后,某区域电网仿真算例验证了该模型的有效性。

Abstract:

Constructing and differentially strengthening anti-disaster backbone power grids can guarantee the power grid security operation and power supply for important loads in extreme disasters. This paper proposes a multi-objective optimization model of backbone power grid considering multi-stage disaster resilience. In this model, the topology and operation importance of nodes and lines in power grids are evaluated quantitatively, and a comprehensive evaluation method based on kernel principal component analysis (KPCA) is proposed. The anti-disaster backbone power grid is optimized for maximizing the survivability, invulnerability and restorability of the power grids within investment constraints. Then, the graph repair strategy and the files learning strategy are embedded in the improved comprehensive learning particle swarm optimization (ICLPSO) algorithm to solve the optimization model, which expands the feasible solution space. Finally, the effectiveness of the proposed model is verified by the simulation results of a regional power grid.
