Wind energy sources are characterized by irregularity and unpredictability. In normal operation, random properties of wind and blade rotational turbulence can produce unwanted fluctuation on the voltage and power supplied into the system. Power output of a wind turbine is a function of wind speed. Wind turbine is a source of power fluctuations due to the nature of wind speed. This fluctuating power will have its impact on power balance and voltage at the point of common coupling. Small variation of wind speed could cause a large variation in the extracted power. As a result, large voltage fluctuation may result in voltage variations outside the regulation limit at connection point. In this paper, a method has been developed to reduce output power fluctuations of a wind turbine with an energy storage system using stator side converter. The developed method has been tested through modelling a doubly fed wind turbine and a battery storage system, using SimPowerSystems tools of MATLAB and simulated for operation as a grid connected system.
Impact and interest:
Citation counts are sourced monthly from and citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
Full-text downloads displays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
