论文摘要
在介绍的研究中，提出了针对地区供暖网络的经济拓扑优化的管道惩罚方法，从基于密度的拓扑优化中汲取灵感。对于地区供暖网络，前期投资是推出该技术的关键因素。如今，管道路由通常依靠基础热传输问题的线性化设计。这项研究建议将最佳的管道路由问题作为非线性拓扑优化问题，从基于密度的拓扑优化中汲取灵感。优化问题是围绕非线性热传输模型提出的，并最大程度地减少了加热网络成本的详细净现值表示。通过放松管道放置的组合问题，该方法对于大规模应用仍然可扩展。通过使用中间管道惩罚策略，可以实现离散的网络拓扑和近乎差异的管道设计。对于现实的测试案例，所提出的算法实现了离散的网络拓扑和近乎差异的管道设计，以优于简单的后处理步骤。
In the presented study, a pipe penalization approach for the economic topology optimization of District Heating Networks is proposed, drawing inspiration from density-based topology optimization. For District Heating Networks, the upfront investment is a crucial factor for the rollout of this technology. Today, the pipe routing is usually designed relying on a linearization of the underlying heat transport problem. This study proposes to solve the optimal pipe routing problem as a non-linear topology optimization problem, drawing inspiration from density-based topology optimization. The optimization problem is formulated around a non-linear heat transport model and minimizes a detailed net present value representation of the heating network cost. By relaxing the combinatorial problem of pipe placement, this approach remains scalable for large-scale applications. A discrete network topology and near-discrete pipe design is achieved by using an intermediate pipe penalization strategy. For a realistic test case, the proposed algorithm achieves a discrete network topology and near-discrete pipe design that outperforms simple post-processing steps.
