  电网内的多个风电场风速往往因为其地理位置的远近而有着不同程度的相关性,采用Nataf 逆变换技术即可建立不同风电场之间具有相关性的风速分布样本空间,进而得到具有相关性的风 电场出力。在仿真过程中考虑风速的不确定性,将每个风电场出力视为一个负的满足威布尔随机 分布的负荷,根据历史数据,用方差—协方差矩阵描述不同风电场相关系数,建立最优潮流模型。 最后,在风电接入改进IEEE 30及IEEE 118节点系统中应用蒙特卡洛仿真计算,定量研究随着风 电场之间相关性的增强,最优潮流结果各项指标的波动情况。(Multiple wind speed within the grid often because of their geographical proximity and have different degrees of relevance, Nataf inverse transform using technology to build wind speed distribution between the sample space with different wind farms correlation, and then get relevant The wind farm output. Consider wind uncertainty in the simulation process, the output of each wind farm to meet the load as a negative Weibull random distribution, based on historical data, variance- covariance matrix of correlation coefficients describing different wind farms, the establishment of optimal fashion models.

15. Compensation-for-Sliding-Mode

  机电传感器通常用于获取转子位置/速度的内置式永磁同步电机( IPMSMs )的高性能控制 车辆系统。然而,使用这些传感器中的增加的成本,尺寸,重量,布线复杂性并减少了IPMSM驱动系统的机械鲁棒性。这些问题连同 一些实用的要求,例如,调速范围广,极端 环境温度和不利的负载条件下,使传感器控制方案可取。本文提出了一种扩展的反电动势( EMF )为基础的滑模 转子位置观测器IPMSMs的无传感器矢量控制。 基于滤波器的特性,一个强大的补偿算法的开发,以改善滑动方式观测器(SMO)的性能。多级滤波器和双滤波器的计划被设计的补偿算法,以进一步改善稳态和瞬态性能,分别。建议SMO和补偿算法通过在MATLAB的Simulink仿真,以及对实验进行验证 实用的永磁同步电动机驱动系统(Electromechanical sensors are commonly used to obtain rotor position/speed for high-performance control of interior permanent magnet synchronous machines (IPMSMs) in vehicle systems. However, the use of these sensors increases the cost, size, weight, wiring complexity and reduces the mechanical robustness of IPMSM drive systems. These issues, together with some practical requirements, e.g., wide speed range, extreme environment temperature, and adverse loading conditions, make a sensorless control scheme desirable. This paper proposes an extended back electromotive force (EMF)-based sliding mode rotor position observer for sensorless vector control of IPMSMs. Based on filter characteristics, a robust compensation algorithm is developed to improve the performance of the sliding-mode observer (SMO). Multistage-filter and dual-filter schemes are designed to further improve the steady-state and transient performance, respectively, of the compensation algorithms. The proposed SMO and c)
