The penetration of multi-carrier energy systems in distribution system gains more and more *** this paper,a bi-level transactive energy trading framework is proposed to improve the energy scheduling and operation efficiency for multi-carrier energy systems which are modeled as energy hubs(EHs).In the upper level,each EH in the distribution system not only makes energy scheduling decisions considering supplies and demands of local energy,but also trades energy with each other to further maximize their social *** associated trading payment among EHs is made in a fair manner by applying Nash bargaining *** solve the bargaining problem by decomposing it into two subproblems:operation cost minimization problem and payment bargaining ***,based on the trading decision,the nodal equivalent loads of EHs are sent to the distribution system operator(DSO)without publishing trading *** applying the second-order cone programming(SOCP),DSO reconfigures the network to reduce the transmission loss of the system in the lower *** network reconfiguration and the trading behavior of EHs interact and iterate until the *** studies on modified IEEE 33-bus distribution system demonstrate the effectiveness of the proposed framework.

目的:探究前段可弯负压吸引鞘(tip-flexible negative pressure ureteral access sheath,tNPUAS)联合一次性输尿管软镜一期治疗2.5~3.0 cm非鹿角状肾结石术后发生全身炎症反应综合征(systemic inflammatory response syndrome,SIRS)的相关危险因素。方法:回顾性分析2022年1月—2023年9月在郑州大学第二附属医院泌尿外科行tNPUAS联合一次性输尿管软镜一期治疗2.5~3.0 cm非鹿角状肾结石患者的临床资料,采用单因素和多因素logistic回归分析筛选与tNPUAS联合一次性输尿管软镜一期治疗2.5~3.0 cm非鹿角状肾结石术后发生SIRS的危险因素,并绘制ROC曲线,评估预测效能。结果:纳入的205例患者中,19例(9.27%)术后发生SIRS。多因素logistic回归分析显示,术前NLR>2.50(OR=2.953,95%CI:1.006~8.669,P=0.049)、AGR95.7 min(OR=1.036,95%CI:1.012~1.060,P=0.003)是术后发生SIRS的独立危险因素。结论:NLR较高、AGR较低、结石平均CT值较小和手术时间较长是tNPUAS联合一次性输尿管软镜一期治疗2.5~3.0 cm非鹿角状肾结石术后SIRS的独立危险因素。术前NLR、ARG及结石平均CT值在预测术后SIRS的发生中具有一定的价值,同时,应严格控制手术时长以降低术后SIRS的发生。
