High-performance predictor for critical unstable generators based on scalable parallelized neural networks
Journal of Modern Power Systems and Clean Energy - Tập 4 - Trang 414-426 - 2016
Youbo LIU, Yang LIU, Junyong LIU, Maozhen LI, Zhibo MA, Gareth TAYLOR
A high-performance predictor for critical unstable generators (CUGs) of power systems is presented in this paper. The predictor is driven by the MapReduce based parallelized neural networks. Specifically, a group of back propagation neural networks (BPNNs), fed by massive response trajectories data, are efficiently organized and concurrently trained in Hadoop to identify dynamic behavior of indivi...... hiện toàn bộ

Multi-dimensional scenario forecast for generation of multiple wind farms
Journal of Modern Power Systems and Clean Energy - Tập 3 - Trang 361-370 - 2015
Ming YANG, You LIN, Simeng ZHU, Xueshan HAN, Hongtao WANG
A novel multi-dimensional scenario forecast approach which can capture the dynamic temporal-spatial interdependence relation among the outputs of multiple wind farms is proposed. In the proposed approach, support vector machine (SVM) is applied for the spot forecast of wind power generation. The probability density function (PDF) of the SVM forecast error is predicted by sparse Bayesian learning (...... hiện toàn bộ
Improved thermal design methodology for wind power converters
Journal of Modern Power Systems and Clean Energy - Tập 1 - Trang 285-291 - 2013
Fei Yang, Liang Guo
This paper presents an improved thermal design methodology for wind power converters. It combines analysis and experimental thermal design tools, including heat transfer correlations, flow network modeling (FNM), computational fluid dynamics (CFD), and experimental measurement techniques. Moreover, a systemic product development process is introduced and an effective combination between the produc...... hiện toàn bộ
Sequential design and global optimization of local power system stabilizer and wide-area HVDC stabilizing controller
Journal of Modern Power Systems and Clean Energy - Tập 4 - Trang 292-299 - 2015
Yong LI, Fang LIU, Yijia CAO
A sequential design and global optimization method is proposed to coordinately design local and wide-area controllers to enhance the overall stability of large-scale power system. The sequential design is used to assign the distributed local power system stabilizer (LPSS) and high-voltage direct current (HVDC) wide-area stabilizing controller (HVDC-WASC) to the concerned damping modes. The global ...... hiện toàn bộ
Fault ride-through of renewable energy conversion systems during voltage recovery
Journal of Modern Power Systems and Clean Energy - Tập 4 - Trang 28-39 - 2016
Ruiqi LI, Hua GENG, Geng YANG
Asymmetrical voltage swells during recovery of a short-circuit fault lead to fluctuations in the dc-link voltage of a renewable energy conversion system (RECS), and may induce reversed power flow and even trip the RECS. This paper studies characteristics of both typical causes resulting in the practical asymmetrical voltage swell and the voltage at the point of common coupling (PCC) during the fau...... hiện toàn bộ
Complete active-reactive power resource scheduling of smart distribution system with high penetration of distributed energy resources
Journal of Modern Power Systems and Clean Energy - Tập 5 - Trang 863-875 - 2017
Abouzar SAMIMI, Mehdi NIKZAD
In traditional power systems, besides the conventional power plants that provide the necessary reactive power in transmission system, the shunt capacitors along with the tap changers of transformers are also employed in distribution networks. In future years, because of the high number of distributed resources integrated into the distribution networks, it will be essential to schedule complete act...... hiện toàn bộ
Long-term system load forecasting based on data-driven linear clustering method
Journal of Modern Power Systems and Clean Energy - Tập 6 - Trang 306-316 - 2017
Yiyan LI, Dong HAN, Zheng YAN
In this paper, a data-driven linear clustering (DLC) method is proposed to solve the long-term system load forecasting problem caused by load fluctuation in some developed cities. A large substation load dataset with annual interval is utilized and firstly preprocessed by the proposed linear clustering method to prepare for modelling. Then optimal autoregressive integrated moving average (ARIMA) m...... hiện toàn bộ
Irregular distribution of wind power prediction
Journal of Modern Power Systems and Clean Energy - Tập 6 - Trang 1172-1180 - 2018
Kun YUAN, Kaifeng ZHANG, Yaxian ZHENG, Dawei LI, Ying WANG, Zhenglin YANG
Wind power is volatile and uncertain, which makes it difficult to establish an accurate prediction model. How to quantitatively describe the distribution of wind power output is the focus of this paper. First, it is assumed that wind speed is a random variable that satisfies the normal distribution. Secondly, based on the nonlinear relationship between wind speed and wind power, the distribution m...... hiện toàn bộ
Centralized multi-agent implementation for securing critical loads in PV based microgrid
Journal of Modern Power Systems and Clean Energy - - 2014
A. SUJIL, Saurabh Kumar AGARWAL, Rajesh KUMAR
The promotion of recent critical load securing of power system research has been directed towards centralized commands and control functions. This paper presents a multi-agent based critical load securing in a PV based microgrid. For the trustworthy operation of critical buildings, the reliability, efficiency and security of the power system should be guaranteed. At present, to increase the securi...... hiện toàn bộ
