Frequency-Voltage Active Support Strategy for Hybrid Wind Farms Based on Grid-Following and Grid-Forming Hierarchical Subgroup Control

引用

CSEE Journal of Power and Energy Systems 2025年第1期11卷 65-77页

作者： Haiyu Zhao Qihang zong Hongyu Zhou Wei yao Kangyi Sun Yuqing Zhou Jinyu Wen State Key Laboratory of Advanced Electromagnetic Technology School of Electrical and Electronics EngineeringHuazhong University of Science and TechnologyWuhan430074China

The GFL-GFM hybrid wind farm (HWF) combines the voltage source control advantages of grid-forming (GFM) wind turbines (WTs) with the current source control advantages of grid-following (GFL) wind turbines. It becomes a new type of large-scale grid-connected wind power generation. In this paper, we propose an HWF frequency-voltage active support based on GFL and GFM hierarchical subgroup control. It aims to realize the support of active power and reactive power under the premise of ensuring system stability. The strategy consists of the determination of the control objectives of the GFM-GFL subgroups, the distributed control (DC) of the GFM-GFL subgroups, and the adaptive control and switching of each unit of the GFM and GFL groups. The GFM-group maintains the grid-connected voltage stability and the GFL-group exhausts the active support. DC at the group level and adaptive control at the unit level are included under the hierarchy of the respective objectives. Finally, a GFL-GFM HWF model is established on the MATLAB/Simulink platform, and the simulation verifies that the proposed strategy can realize the enhancement of the frequency-voltage support capability of the HWF under the premise of grid-connected stability.

随着自主水下机器人(AUV)和无人水面艇(USV)在民用和军事领域的应用不断扩展, USV与AUV协同完成相关任务的作业模式受到了广泛关注.针对多USV和多AUV协同访问多目标点的任务分配问题进行研究,旨在最小化多USV和AUV系统访问所有目标点的总旅行距离.首先,建立考虑通信约束和AUV最大航程约束的多USV多AUV协同多点访问任务分配问题的数学模型,并对问题的NP-hard属性进行分析.其次,提出一个两阶段任务分配算法:1)先利用最小边际代价算法构建各USV访问完所有水面目标点的路径,再采用最近插入策略分配水下目标点;2)通过多个邻域搜索算子对初始解进行优化,得到可行最终解.相对于已有流行的自组织映射算法,仿真实验表明所提出任务分配算法能在较短计算时间内得到质量较优的任务分配方案.

Realization of edge states along a synthetic orbital angular momentum dimension

Photonics Research 2025年第1期13卷 87-97页

Synthetic dimensions have emerged as promising methodologies for studying topological physics, offering great advantages in controllability and flexibility. Photonic orbital angular momentum(OAM), characterized by discrete yet unbounded properties, serves as a potent carrier for constructing synthetic dimensions. Despite the widespread utilization of synthetic OAM dimensions in the investigation of topological physics, the demonstration of an edge along such dimensions has remained challenging, significantly constraining the exploration of important topological edge effects. In this study, we establish an edge within a Floquet Su–Schrieffer–Heeger OAM lattice, creating approximate semi-infinite lattices by introducing a pinhole in the optical elements within a cavity. Leveraging the spectral detection capabilities of the cavity, we directly measure the phase transitions of zero(±π) energy edge states, elucidating the principle of bulk-edge correspondence. Furthermore, we dynamically observe the migration of edge modes from the gap to the bulk by varying the edge phase, and we reveal that interference near the surface results in the discretization of the spectrum. We offer, to our knowledge,a novel perspective for investigating edge effects and provide an important photonic toolbox in topological photonics.

研究一类考虑节点隐私保护的分布式优化问题,目标为保护各智能体的隐私信息不被泄露,并最小化所有智能体局部成本函数之和.首先,针对无向连通图,提出一种基于椭圆曲线密码机制的分布式凸优化算法.通过设计底层权重矩阵,将基于椭圆曲线的ELGamal同态加密和数字签名与分布式次梯度算法相结合,克服了椭圆曲线密码机制与分布式一致性策略无法结合的难点.在无第三方或聚合器的场景下,该算法实现了系统的隐私保护.理论分析表明,该算法能够渐近收敛至全局最优解,并适用于时变通信拓扑的动态环境.此外,算法能有效保护智能体的状态和成本函数不受来自诚实但好奇攻击者、外部窃听者和篡改攻击者的威胁.最后,通过数值仿真验证了算法的有效性.

探索创业型企业员工创造力的来源和影响因素有助于帮助企业提高竞争力。根据资源保存理论,家庭角色对员工工作创造力可以产生显著影响。通过引入创造力认知的双路径模型,检验了员工家庭—工作资源外溢对员工创造力的影响机制。结果显示:家庭—工作资源外溢可以通过提高认知灵活性和认知持久性进而提升员工创造力;在信息通信技术情境下员工的认知灵活性可以更好地被家庭资源激发,但认知持久性则会被削弱。进一步研究发现,高工作正念的员工可以抵御信息通信技术使用对认知持久性的负面作用。研究结论为信息通信技术情境下创业企业员工创造力的家庭来源提供了一些新的见解。
