Wind power is one of the fastest growing renewable sources of energy generation in the U.S. and many other countries. Wind energy is a desirable resource because it's cheap and clean. However, it's intermittent, and the profile of energy generation does not correlate with the demand cycle. Basically, wind energy is available when the wind blows, and the power level depends on wind speed. Therefore, they are not dispatchable in the traditional sense. As installed wind capacity grows in a region, the intermittency of wind energy becomes a significant issue. One possibility to achieve higher system flexibility and security is energy storage investment. In this paper, Compressed Air Energy Storage (CAES) is considered to store electricity. This study presents a formulation of Security-Constrained Unit Commitment (SCUC) with integration of a compressed air energy storage (CAES) and wind generation. A case study is presented to validate the proposed model.","PeriodicalId":171339,"journal":{"name":"2010 World Non-Grid-Connected Wind Power and Energy Conference","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128953839","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The modal characteristics are extracted based on the wind turbine model established in the laboratory. Using harmonic analysis of FEM, the excitation forces on the blades caused by the stochastic wind load are imposed on the rotor model and the stable response of the rotor system is calculated using ANSYS.
