高可靠性供电和大规模分布式电源友好接入推动了有源配电网采取合环运行方式。为满足合环运行的安全性和经济性要求,实现满额消纳清洁能源,提出了基于背靠背柔性直流的配电网安全合环和潮流优化控制方法。分析了背靠背柔性直流的注入功率模型和控制方式,考虑配电网与主网最优运行的差异,建立了以售电企业综合供电成本最低为目标,以网络潮流、分布式能源出力和柔性直流功率平衡等为约束的配电网合环最优运行模型。基于修改的IEEE 33节点系统,多种运行方式下的仿真算例验证了背靠背柔性直流实现配电网安全合环、环网潮流经济分布和规模化分布式电源满额消纳等目标的可行性和有效性。

Micro-extrusion compression molding and surface modification were proposed for the mass fabrication of a superhydrophobic thermoplastic polyurethane sensor (TCGS).Inspired by scorpions, TCGS features Archimedean spiral crack arrays and micropores, achieving 218.13 sensitivity at 2% strain, a 4300% increase, and over 5000 usage cycles of *** robust superhydrophobicity of TCGS improves sensitivity and stability for detecting small-scale liquid leakage, allowing precise monitoring across various sizes and compositions while providing early warnings in various scenarios. Liquid leakage of pipeline networks not only results in considerable resource wastage but also leads to environmental pollution and ecological imbalance. In response to this global issue, a bioinspired superhydrophobic thermoplastic polyurethane/carbon nanotubes/graphene nanosheets flexible strain sensor (TCGS) has been developed using a combination of micro-extrusion compression molding and surface modification for real-time wireless detection of liquid leakage. The TCGS utilizes the synergistic effects of Archimedean spiral crack arrays and micropores, which are inspired by the remarkable sensory capabilities of scorpions. This design achieves a sensitivity of 218.13 at a strain of 2%, which is an increase of 4300%. Additionally, it demonstrates exceptional durability by withstanding over 5000 usage cycles. The robust superhydrophobicity of the TCGS significantly enhances sensitivity and stability in detecting small-scale liquid leakage, enabling precise monitoring of liquid leakage across a wide range of sizes, velocities, and compositions while issuing prompt alerts. This provides critical early warnings for both industrial pipelines and potential liquid leakage scenarios in everyday life. The development and utilization of bioinspired ultrasensitive flexible strain sensors offer an innovative and effective solution for the early wireless detection of liquid leakage.
