Abstract

Distributed photovoltaic power systems, typically deployed in complex scenarios like irregular rooftops, present a challenging detailed cable routing problem (DCRP). This involves grouping solar modules and routing cables to connect each group, traditionally addressed through manual design. This paper presents a variable-depth large neighborhood search (VDLNS) algorithm to address the DCRP, which is modeled as a specialized cycle covering problem using arc-flow and partition formulations. A cycle-split heuristic, derived from DCRP’s connection to the traveling salesman problem, is introduced and combined with a series of destroy operators to construct the VDLNS algorithm. Numerical experiments conducted on both synthetic and real-world instances validated the algorithm’s efficacy, achieving an average total cost reduction of 12.87% on house rooftop instances compared to manual design. The results indicate that the method effectively streamlines photovoltaic system design by delivering cost-efficient cable routing schemes within a reasonable timeframe.

分布式光伏系统中电缆布线的可变深度大邻域搜索算法
分布式光伏发电系统通常部署在不规则屋顶等复杂场景中,这就提出了一个具有挑战性的详细电缆布线问题(DCRP)。这涉及到太阳能模块的分组和连接各组的电缆布线,传统上是通过人工设计来解决的。本文提出了一种可变深度大邻域搜索(VDLNS)算法来解决 DCRP 问题,该算法使用弧流和分割公式将 DCRP 建模为一个专门的循环覆盖问题。从 DCRP 与旅行推销员问题的联系中得出的循环分割启发式被引入并与一系列破坏算子相结合,从而构建了 VDLNS 算法。在合成实例和真实世界实例上进行的数值实验验证了该算法的有效性,与人工设计相比,该算法在房屋屋顶实例上平均降低了 12.87% 的总成本。结果表明,该方法能在合理的时间内提供具有成本效益的电缆布线方案,从而有效简化光伏系统设计。
