为提高大规模风电并网后电网频率稳定性,降低风储系统调频成本,提出考虑虚拟控制参数调节的优化模型预测控制策略。首先,计及储能系统对电网惯性水平与阻尼能力的作用,引入双曲正切函数自适应调节储能系统虚拟控制参数,满足不同时段的调频需求。然后,基于风储系统状态方程建立预测模型,以频率偏差与调频成本最小为控制目标,设计自适应模型预测控制策略。最后,搭建仿真模型,在阶跃和连续负荷扰动工况下对不同控制策略的效果进行对比分析。结果表明,所提控制策略能够有效改善电网调频效果,优化储能系统和风电机组的出力,具有更优的协同控制性能。

In order to solve the urgent problem of how to manage and sustain highway tunnels with advanced information technology with the background of the rapid development in the modem traffic, and achieve the cost- effectiveness optimal principle objectives under the premise of guaranteeing a smooth flow of traffic; a highway tunnel maintenance and management system framework and the key modules were proposed. First, the determined highway tunnel condition assessment index system was established according to the result of expert consulting forms. Secondly, the tunnel diseases, the corresponding maintenance measurements, and many-to-many relationship between diseases and maintenance measurements were introduced. Then, three kinds of 0-1 integer programming models were built according to different tunnel operators＇ needs in the optimization decision module. Finally, the further development and implementation of the system was prospected. The research results can provide references to tunnel researchers and managers.

腹部动脉、静脉或门静脉系统形态及功能改变与很多腹部疾病有关,因此腹部血流动力学的综合评估对很多临床诊治至关重要,但由于解剖学、正常生理学和各种病理异常的巨大复杂性而面临挑战。四维血流核磁共振(4D flow MRI)非常有效地结合了非侵入性及侵入性检查(如超声,血管造影,CT等)的优点,是一种新型的相位对比MRI技术,能全面无创的可视化和定量的评价腹部不同血管区域和器官中的腹部血流,同时有助于了解病理生理机制,是一种非常有潜力的全面评估腹部循环的技术。本文主要对4D flow技术在腹部中的应用进展进行综述,为临床对疾病的诊断和治疗以及科研提供新的方向和思路。

In this paper, we point out that most results on abelian (complex) W~*-algebras hold in the real case. Of course, there are differences in homeomorphisms of period 2. Moreover, an abelian real Von Neumann algebra not containing any minimal projection on a separable real Hilbert space is * isomorphic to L_r~∞([0,1]) (all real functions in L~∞ ([0, 1])), or L~∞([0, 1])(as a real W~*-algebra), or L_r~∞([0,1]) L_∞([0, 1]) (as a real W~*-algebra), and it is different from the complex case.
