Voltage Control for Distribution Networks via Coordinated Regulation of Active and Reactive Power of DGs
收藏 引用
IEEE TRANSACTIONS ON SMART GRID 2020年 第5期11卷 4017-4031页
作者: Hu, Xiong Liu, Zhi-Wei Wen, Guanghui Yu, Xinghuo Liu, Chen Huazhong Univ Sci & Technol Sch Artificial Intelligence & Automat Wuhan 430074 Peoples R China Huazhong Univ Sci & Technol Key Lab Image Proc & Intelligent Control Minist Educ Wuhan 430074 Peoples R China Southeast Univ Sch Math Dept Syst Sci Nanjing 210096 Peoples R China RMIT Univ Sch Engn Melbourne Vic 3001 Australia
Fast-acting reactive power support from distributed generations (DGs) is a promising approach for tackling rapid voltage fluctuations in distribution networks. However, the voltage regulation range via reactive power ... 详细信息

EFFICIENT CONSTRUCTION OF TENSOR RING REPRESENTATIONS FROM SAMPLING
收藏 引用
MULTISCALE MODELING & SIMULATION 2021年 第3期19卷 1261-1284页
作者: Khoo, Yuehaw Lu, Jianfeng Ying, Lexing Univ Chicago Dept Stat Chicago IL 60637 USA Duke Univ Dept Phys Durham NC 27708 USA Duke Univ Dept Chem Durham NC 27708 USA Duke Univ Dept Math Durham NC 27708 USA Stanford Univ Dept Math Stanford CA 94305 USA
In this paper we propose an efficient method to compress a high dimensional function into a tensor ring format, based on alternating least squares (ALS). Since the function has size exponential in d, where d is the nu... 详细信息

STOCHASTIC PROCESSES AND THEIR APPLICATIONS 1997年 第2期71卷 165-185页
作者: Aldous, D Lovasz, L Winkler, P YALE UNIV DEPT COMP SCINEW HAVENCT 06510 AT&T BELL LABS MURRAY HILLNJ 07960
Consider the class of discrete time, general state space Markov chains which satisfy a ''uniform ergodicity under sampling'' condition. There are many ways to quantify the notion of ''mixing ti... 详细信息

Preconditioned Data Sparsification for Big Data With Applications to PCA and K-Means
收藏 引用
IEEE TRANSACTIONS ON INFORMATION THEORY 2017年 第5期63卷 2954-2974页
作者: Pourkamali-Anaraki, Farhad Becker, Stephen Univ Colorado Dept Elect Comp & Energy Engn Boulder CO 80309 USA Univ Colorado Dept Appl Math Boulder CO 80309 USA
We analyze a compression scheme for large data sets that randomly keeps a small percentage of the components of each data sample. The benefit is that the output is a sparse matrix, and therefore, subsequent processing... 详细信息

Shrinking Maxima, Decreasing Costs: New Online Packing and Covering Problems
收藏 引用
algorithmICA 2016年 第4期74卷 1205-1223页

SIAM JOURNAL ON MATRIX ANALYSIS AND APPLICATIONS 2017年 第2期38卷 425-433页
作者: Szlam, Arthur Tulloch, Andrew Tygert, Mark Facebook Artificial Intelligence Res Menlo Pk CA 94025 USA
A few iterations of alternating least squares with a random starting point provably suffice to produce nearly optimal spectral- and Frobenius-norm accuracies of low-rank approximations to a matrix;iterating to converg... 详细信息
