摘要:

建设抗灾型骨干网架对增强极端自然灾害下电力系统的供电能力具有重要意义。为此,提出一种兼顾经济性和可靠性的抗灾型骨干网架规划方法。首先,采用全寿命周期内的加固成本和减损效益来表征规划方案的经济性和可靠性,以骨干网架单位加固成本对原始网架产生的单位减损效益最大为目标函数,并以网络拓扑连通性和系统安全运行为刚性约束,构建抗灾型骨干网架优化模型。其次,通过改进的纵横交叉优化(improved crisscross optimization,ICSO)算法求解该模型,寻求最优规划方案。最后,通过IEEE 30节点系统的仿真分析验证了所提方法的有效性。

关键词: 电网规划, 抗灾型骨干网架, 全寿命周期成本, 纵横交叉优化(CSO)

Abstract:

The construction of anti-disaster backbone grid is of great significance to enhance the power supply capacity of power system under extreme natural disasters. Comprehensively considering economy and reliability, a planning method for anti-disaster backbone grid was proposed. The economy and reliability of the planning scheme were expressed as the strengthened cost and the benefit from loss reduction in life cycle. The objective function was to maximize the unit benefit from loss reduction of the original grid caused by the unit strengthened cost of backbone grid. Taking the network connectivity and safe operation of power system into account, a planning model for anti-disaster backbone grid was established. The model was solved by the improved crisscross optimization (ICSO) algorithm to find the optimal planning scheme. Finally, the effectiveness of the proposed method was verified by the simulation analysis of the IEEE 30-bus system.

Key words: power grid planning, anti-disaster backbone grid, life cycle cost, crisscross optimization (CSO)
