随着能源系统的去中心化程度不断加深，分解协调式算法开始广泛应用于求解能源领域的优化问题。但是，分解协调式算法需要子优化问题向协调层算法上传协调变量，存在隐私泄露的风险，并且协调层自身还存在着信任问题。为了解决这些问题，引入Paillier加密和区块链共识机制，对分解协调式算法进行改进。在分解协调式算法的每次迭代中，各个发电商的出力通过Paillier加密后以密文的形式广播给其他发电商，某个发电商作为领导节点负责根据密文计算出所有发电商的总出力，并将所有密文和总出力打包生成区块后广播给所有发电商。所有发电商都会对区块内容的正确性进行检查，检查通过后将区块加入到账本中，完成分解协调式算法的本次迭代。算例结果证明了该算法中Paillier加密能够保护各个发电商的隐私，共识机制能够防止领导节点恶意篡改区块内容，在发电商间构建信任。

具有极强随机性和不确定性的分布式能源、可控负荷、电动汽车等的发展，既给电力系统的灵活性问题带来挑战，又可以作为灵活性资源（flexible resources,FRs）给电网带来机遇。虚拟电厂（virtual power plant,VPP）作为FRs集成聚合的主要形式，实现对海量灵活性闲散资源终端的聚能、储能、供能与用能。该研究聚焦于VPP内部的资源管理，首先从能量、空间、时间三个尺度指出VPP实施资源集群及协同调控过程中面临的技术挑战；然后阐述云管边端架构下VPP的层级结构与基本功能，并对资源建模、资源集群、协同调控涉及的关键技术及相关通信方法进行综述；最后对未来VPP需要探索的研究方向进行了展望。

随着燃气机组的广泛应用和电转气技术的快速发展，电力系统与天然气系统之间的互动日益密切，电力-天然气耦合系统是在该背景下形成的用于描述两个能源系统紧密耦合的系统形式。该耦合系统除了具有两个能源系统分别的运行特性和安全约束外，还因系统间的耦合互动产生了新的特点和约束，亟需新的分析和控制方法，近年来已经获得了国内外众多专家学者的关注和深入研究。文章从电力-天然气耦合系统的建模仿真、优化规划、运行分析（优化调度、安全评估）的角度对当前的主要研究成果进行了综述，同时总结了目前国内外学者对耦合市场的探索，最终对当前研究的不足和未来的研究方向进行了探讨。

Ensuring consistency and validity in flight training assessment proves challenging due to the traditional reliance on instructors' subjective evaluations and the imprecise quantitative criteria for competencies. A novel mathematical model based on the VENN model was introduced to evaluate behavioral indicators displayed during flight training across three dimensions: quantity, frequency, and the outcomes of threat and error management. Transforming the examination of subjects in flight training into a quantitative evaluation of abilities, and combining historical inspection work sheet data, an optimization method for competency evaluation standards was proposed. Finally, the effectiveness of the proposed method was validated using an actual manual flight control skill evaluation as an example. The results demonstrate a significant correlation between the final assessment criteria derived from the algorithm and the ratings provided by instructors, with 83. 3% of the samples exhibiting rating consistency and the remaining samples deviating by no more than one level. This suggests that the proposed method adeptly transforms historical checklist information into assessment criteria for competency, offering theoretical support and a new data-driven approach for formulating competency assessment criteria.

Objective To observe the effectiveness of flexible bronchoscope local cryotherapy combined with absolute ethanol injection in the treatment of scarring stenosis bronchial tuberculosis-related airway occlusion. Methods Ninety cases of bronchial tuberculosis with scarring stenosis were selected. All patients received bronchoscopy interventional therapy on the basis of routine anti-tuberculosis therapy. According to the different interventional therapy, they were divided into cryotherapy group (30 cases), injection group (30 cases) and combination group (30 cases), Patients in the cryotherapy group received local cryotherapy under bronchoscopy, the injection group received local absolute ethanol injection under bronchoscopy, and the combination group received local cryotherapy combined with absolute ethanol injection under bronchoscopy. The clinical effectiveness of the three groups was assessed three months after treatment, and the overall effective rate was calculated. The arterial blood gas analysis indexes (arterial partial pressure of carbon dioxide (PaO2), and arterial partial pressure of oxygen (PaO2), and pulmonary function indexes (tracheal diameter, FEV1, 6-min walking distance) were observed and compared between the three groups before and after treatment. The patients were followed up for 3 months, and the occurrence of complications in the three groups was recorded. Results The total effective rate of the combination group was higher than those of the freezing group and the injection group (both P<0. 05), After treatment, the tracheal diameter, FEV1, and 6-minute walking distance increased in these three groups (all P<0. 05), Compared with the cryotherapy group and the injection group, the tracheal diameter, FEV1, and 6-minute walking distance increased in the combination group (all P<0. 05), After treatment, the PaO2 levels increased and the PaO2 levels decreased in these three groups (all P<0. 05), Compared with the cryotherapy group and the injection group, the PaO2 level increased and the PaO2 level decreased in the combination group (all P<0. 05), No serious complications such as pneumothorax and massive hemoptysis occurred in the three groups, and the incidence of complications was low, and there was no significant difference in the incidence of complications among these three groups (all P<0. 05), Conclusions The local cryotherapy combined with absolute ethanol injection therapy under bronchoscopy is effective in treating airway occlusion of scarring stenosis bronchial tuberculosis. It can effectively improve pulmonary function and the status of arterial blood gas without increasing complications. [ABSTRACT FROM AUTHOR]
