摘要

本文提出了一种提高架空配电网可靠性和降低成本的优化方法，重点是尽量减少雷击造成的停电。该研究分析了不同的保护策略，如安装避雷器，使用屏蔽电缆，改善接地系统，考虑到土壤条件的变化。跨多个场景的模拟有助于确定具有成本效益的解决方案，以增强网络性能。关键的可靠性指标，如SAIDI和SAIFI，进行评估，以衡量这些改进的影响。该优化模型可确保保护系统的投资在不超出预算的情况下达到可靠性目标。结果表明，综合保护措施显著提高了网络可靠性，优化配置可降低SAIDI和SAIFI。此外，研究结果强调了根据特定网络条件调整保护策略的重要性，以确保投资和性能改进之间的有效平衡。

Multi-objective optimization of reliability and cost efficiency in lightning protection for overhead distribution systems

This paper presents an optimization approach to improve reliability and reduce costs in overhead power distribution networks, with a focus on minimizing outages caused by lightning strikes. The study analyzes different protection strategies, such as installing surge arresters, using shielded cables, and improving grounding systems, considering variations in soil conditions. Simulations across multiple scenarios help identify cost-effective solutions to enhance network performance. Key reliability indicators, such as SAIDI and SAIFI, are evaluated to measure the impact of these improvements. The optimization model ensures that investments in protection systems achieve reliability targets while staying within budget. The results demonstrate that integrated protection measures significantly improve network reliability, with optimized configurations leading to reductions in SAIDI and SAIFI. Additionally, the findings highlight the importance of adapting protection strategies to specific network conditions, ensuring an effective balance between investment and performance improvements.
