Guest Editorial Special Section on Wind Energy

T

HE current confluence of positive economic conditions, technical developments, and enhanced environmental awareness has led to vigorous efforts toward making wind power a key component of available energy resources. Under these circumstances, the current trend of increasing wind power is not likely to abate in the near future. Rather, large wind power plants and increasing levels of wind power penetration are likely to become more common throughout the world. This Special Section, Power System Performance Issues Associated with Wind Energy, recognizes the rising prominence of wind energy as a viable source of electric power. The objective of the section is to provide a wide perspective on different aspects associated with wind power as it relates to power system engineering, with an emphasis on dynamic modeling and simulation. The work for the Special Section began with a Call for Abstracts in the Spring of 2006. From more than 70 abstracts submitted, the Editors invited the authors of 21 abstracts to write full papers. The full papers were then submitted for review through the IEEE/PES Transaction review process. The final set of 11 manuscripts address important and timely topics in wind power generation. Smith et al. set the scene by detailing the state of the art in wind integration and impacts. Utility Wind Integration and Operating Impact State of the Art There is a set of two papers (Erlich et al. and Estanqueiro) that report on dynamic modeling and simulation of wind turbines for power system studies. Modeling of Wind Turbines Based on Doubly-Fed Induction Generators for Power System Stability Studies A Dynamic Wind Generation Model for Power System Studies This is followed by two contributions from power system operators who report on their experience of using dynamic models of wind turbines in power system studies (Coughlan et al.) and on some results of these studies (Akhmatov and Børre Eriksen). Wind Turbine Modeling for Power System Stability Analysis—A System Operator Perspective A Large Wind Power System in Almost Island Operation—A Danish Case Study

Wind turbines participating in frequency control is the topic of papers by Lubosny and Bialek and by de Almeida and Peças Lopes. Supervisory Control of a Wind Farm Participation of Doubly Fed Induction Wind Generators in System Frequency Regulation Modeling wind power fluctuations and variations and their impact on power systems is the subject of papers by Boehme et al. and Sørensen et al. Applying Time Series to Power Flow Analysis in Networks with High Wind Penetration Power Fluctuations from Large Wind Farms In the concluding papers, Causebrook et al. investigate a novel technique of fault ride through, and Xu investigates one aspect of connecting wind farms to the transmission system via HVDC. Fault Ride-Through of Large Wind Farms Using Series Dynamic Braking Resistors Grid Integration of Large DFIG-Based Wind Farms Using VSC Transmission It is our hope that readers find this collection of papers informative. Perhaps more importantly, we also hope that the information included in the papers provides an added incentive for advancing our current knowledge of wind power engineering and power system dynamics. ACKNOWLEDGMENT The Guest Editors would like to thank the Editor-in-Chief of the IEEE TRANSACTIONS ON POWER SYSTEMS, Dr. V. Vittal, for providing the support and guidance for the publication of this Special Section. They would also like to thank all the reviewers for their time and expertise and to all the authors for their contributions.
