| 1 | Power System State Estimation Solution With Zero Injection Constraints Using Modified Newton Method and Fast Decoupled Method in Polar Coordinate显示文摘如何保证零注入节点的注入功率在状态估计结果中严格为0是电力系统状态估计研究中的重要问题。在直角坐标下,由于零注入约束为线性约束,可使用修正牛顿法来有效地解决这一问题。因此,借鉴直角坐标下修正牛顿法的思路,提出了极坐标下的修正牛顿法和修正快速解耦估计。这些方法的计算流程与传统的极坐标下的牛顿法和快速解耦估计非常相似,计算速度与大权重法相当,同时能够保证零注入约束严格满足。仿真结果验证了所得结论。 | GUO Ye ZHANG Boming WU Wenchuag SUN Hongbin | 2012 | 中国电机工程学报2012，32，22： | 13 |
| 2 | Rule Extraction in Transient Stability Study Using Linear Decision Trees显示文摘为了提高精细规则的性能,提出一种基于支持样本的线性决策树的规则提取方法。该方法筛选临近稳定边界的支持样本,作为决策树的输入样本,精简了样本数目;提出基于线性分类器的决策树方法,以得到基于组合属性的安全稳定运行规则。在单机无穷大系统和IEEE 39节点系统中的对比研究表明:由于考虑了支持样本的特殊性,用线性组合规则代替单属性规则,减少了计算时间,提高了泛化能力,丰富了规则的物理含义,得到的灵敏度信息可用于辅助决策,在安全稳定精细规则提取中具有应用潜力。 | SUN Hongbin WANG Kang ZHANG Boming ZHAO Feng | 2011 | 中国电机工程学报2011，31，34： | 11 |
| 3 | A two-level hierarchical discrete-device control method for power networks with integrated wind farms显示文摘Power systems depend on discrete devices, such as shunt capacitors/reactors and on-load tap changers, for their long-term reliability.In transmission systems that contain large wind farms, we must take into account the uncertainties in wind power generation when deciding when to operate these devices.In this paper, we describe a method to schedule the operation of these devices over the course of the following day.These schedules are designed to minimize wind-power generation curtailment, bus voltage violations, and dynamic reactive-power deviations,even under the worst possible conditions.Daily voltagecontrol decisions are initiated every 15 min using a dynamic optimization algorithm that predicts the state of the system over the next 4-hour period.For this, forecasts updated in real-time are employed, because they are more precise than forecasts for the day ahead.Day-ahead schedules are calculated using a two-stage robust mixedinteger optimization algorithm.The proposed control strategies were tested on a Chinese power network with wind power sources; the control performance was also validated numerically. | Fengda XU Qinglai GUO Hongbin SUN Boming ZHANG Lin JIA | 2019 | Journal of Modern Power Systems and Clean Energy2019，7，1： | 2 |
| 4 | Stress transfer around a broken fiber in unidirectional fiber-reinforced composites considering matrix damage evolution and interface slipping显示文摘A shear-lag model is applied to study the stress transfer around a broken fiber within unidirectional fiber-reinforced composites(FRC) subjected to uniaxial tensile loading along the fiber direction.The matrix damage and interfacial debonding,which are the main failure modes,are considered in the model.The maximum stress criterion with the linear damage evolution theory is used for the matrix.The slipping friction stress is considered in the interfacial debonding region using Coulomb friction theory,in which interfacial clamping stress comes from radial residual stress and mismatch of Poisson's ratios of constituents(fiber and matrix).The stress distributions in the fiber and matrix are obtained by the shear-lag theory added with boundary conditions,which includes force continuity and displacement compatibility constraints in the broken and neighboring intact fibers.The result gives axial stress distribution in fibers and shear stress in the interface and compares the theory reasonably well with the measurement by a polarized light microscope.The relation curves between damage,debonding and ineffective region lengths with external strain loading are obtained. | YANG Zhong ZHANG BoMing ZHAO Lin SUN XinYang | 2011 | Science China(Physics,Mechanics & Astronomy)2011，54，2： | 2 |

| 14 | Magnetic Resonance Image-Based Modeling for Neurosurgical Interventions显示文摘Surgeries such as implantation of deep brain stimulation devices require accurate placement of devices within the brain.Because placement affects performance,image guidance and robotic assistance techniques have been widely adopted.These methods require accurate prediction of brain deformation during and following implantation.In this study,a magnetic resonance(MR)image-based finite element(FE)model was proposed by using a coupled Eulerian-Lagrangian method.Anatomical accuracy was achieved by mapping image voxels directly to the volumetric mesh space.The potential utility was demonstrated by evaluating the effect of different surgical approaches on the deformation of the corpus callosum(CC)region.The results showed that the maximum displacement of the corpus callosum increase with an increase of interventional angle with respect to the midline.The maximum displacement of the corpus callosum for different interventional locations was predicted,which is related to the brain curvature and the distance between the interventional area and corpus callosum(CC).The estimated displacement magnitude of the CC region followed those obtained from clinical observations.The proposed method provided an automatic pipeline for generating realistic computational models for interventional surgery.Results also demonstrated the potential of constructing patient-specific models for image-guided,robotic neurological surgery. | Yongqiang Li Changxin Lai Chengchen Zhang Alexa Singer Suhao Qiu Boming Sun Michael S.Sacks Yuan Feng | 2019 | Molecular & Cellular Biomechanics2019，16，4： | 0 |
