  • Deviation Management of Wind Power Prediction and Decision-Making of Wind Power Bidding
    Power system technology, 2011
    Co-Authors: Wang Tao
    Abstract:

    The deviation of Wind Power prediction lead to a lot of adjustment cost for AGC,so how to utilize the incentive policy to improve the prediction accuracy of Wind Power is significant for secure and economic operation of Power grid.The examination and management of prediction accuracy of Wind Power participated in market transaction and the optimal bidding of Wind farm output are researched.Referring to present method to exam the generated Power of conventional Power plants by grid dispatch cooperation,a method to exam the uncertainty of Wind Power prediction is given;according to the probability density of Wind Power prediction and taking the maximum revenue expectation of Wind farm as objective,a optimal decision-making strategy for the bidding of Wind Power is proposed.Case study results show that the proposed method can improve the accuracy of Wind Power prediction.

  • Long-Term Wind Power Variability
    2012
    Co-Authors: Yih-huei Wan
    Abstract:

    The National Renewable Energy Laboratory started collecting Wind Power data from large commercial Wind Power plants (WPPs) in southwest Minnesota with dedicated dataloggers and communication links in the spring of 2000. Over the years, additional WPPs in other areas were added to and removed from the data collection effort. The longest data stream of actual Wind plant output is more than 10 years. The resulting data have been used to analyze Wind Power fluctuations, frequency distribution of changes, the effects of spatial diversity, and Wind Power ancillary services. This report uses the multi-year Wind Power data to examine long-term Wind Power variability.

  • Wind Power Plant Behaviors: Analyses of Long-Term Wind Power Data
    2004
    Co-Authors: Yih-huei Wan
    Abstract:

    The Wind industry's growth is hampered by many market barriers, some of which stem from utilities' lack of experience with the technology. The effects of Wind Power fluctuations on Power system operations and requirements of ancillary services for Wind Power have increasingly become concerns for many electric utilities and Wind Power developers. To remedy the situation, NREL has undertaken a project to record long-term, high-resolution Wind Power output data from large Wind Power plants in various regions.

  • Analysis and countermeasures of Wind Power curtailment in China
    Renewable & Sustainable Energy Reviews, 2015
    Co-Authors: Xiao-chao Fan, Ruijing Shi, Wei Qing Wang, Feng Ting Li
    Abstract:

    The year 2010 was an important turning point in China׳s Wind Power industry. The main contradiction in China׳s Wind Power development shifted to a conflict between large-scale rapid development of Wind Power capacity and Power transmission and consumption. The present Wind Power curtailment restricts the sound development of China׳s Wind Power industry. In this study, the situation of Wind Power curtailment is reviewed through the data summary and analysis of more than 10 provinces, including Inner Mongolia and Xinjiang, in the past five years. Within the context of China׳s overall Power structure and based on the characteristics of different regions, this study analyzes the parameters affecting Wind Power curtailment to determine the factors affecting Wind Power curtailment in China, summarize the specific reasons for Wind Power accommodation, and discuss the methods and strategies to reasonably solve the Wind Power curtailment issue in different regions of China. Specific measures include strengthening the Power grid construction to realize the transmission of Wind Power from north to east, constructing demonstration projects of Wind Power heating to promote local Wind Power accommodation in four provinces in Northwest China, and using Wind Power storage to minimize the difficulty of Wind Power curtailment. Predictions and prospects for the development of China׳s Wind Power industry are also presented in this paper.

  • Wind Power Transmission System Integration — a Case Study of China Wind Power Base
    2020
    Co-Authors: Shutang You
    Abstract:

    Due to a series of supporting policies in recent years, China Wind Power has developed rapidly through a large-scale and centralized mode. This paper analyzes the two major concerns faced by China’s Wind Power development: Wind generation reliability and Wind energy balancing. More specifically, Wind farm tripping-off-grid incidents and Wind Power curtailment issues, which caused huge economical loss, are investigated in details. Based on operation experience of large Wind Power bases, technical recommendations and economic incentives are proposed to improve Wind Power integration and Power grid reliability. As a summary and outlook of Wind Power development in China, this paper provides a reference on future Wind Power development for other countries.

  • Flexible Transmission Expansion Planning for Integrating Wind Power Based on Wind Power Distribution Characteristics
    Journal of Electrical Engineering & Technology, 2015
    Co-Authors: Jianxue Wang, Shutang You, Ruogu Wang, Yunhao Li, Pingliang Zeng, Yao Zhang
    Abstract:

    Traditional transmission planning usually caters for rated Wind Power output. Due to the low occurrence probability of nominal capacity of Wind Power and huge investment in transmission, these planning methods will leads to low utilization rates of transmission lines and poor economic efficiency. This paper provides a novel transmission expansion planning method for integrating large- scale Wind Power. The Wind Power distribution characteristics of large-scale Wind Power output and its impact on transmission planning are analyzed. Based on the Wind Power distribution characteristics, this paper proposes a flexible and economic transmission planning model which saves substantial transmission investment through spilling a small amount of peak output of Wind Power. A methodology based on Benders decomposition is used to solve the model. The applicability and effectiveness of the model and algorithm are verified through a numerical case.
