In particular, the greater penetration of wind generation in European power networks is, at times, displacing a significant capacity of conventional synchronous generation with fixed-speed induction generation and now more commonly, doubly fed induction generators. The impact of such changes in the generation mix requires careful monitoring to assess the impact on transient and dynamic stability. This study presents a measurement-based method for the early detection of power system oscillations, with consideration of mode damping, in order to raise alarms and develop strategies to actively improve power system dynamic stability and security. A method is developed based on wavelet-based support vector data description (SVDD) to detect oscillation modes in wind farm output power, which may excite dynamic instabilities in the wider system. The wavelet transform is used as a filter to identify oscillations in frequency bands, whereas the SVDD method is used to extract dominant features from different scales and generate an assessment boundary according to the extracted features. Poorly damped oscillations of a large magnitude, or that are resonant, can be alarmed to the system operator, to reduce the risk of system instability. The proposed method is exemplified using measured data from a chosen wind farm site.", "publicationTitle": "Renewable Power Generation, IET", "publisher": "", "place": "", "date": "2010", "volume": "4", "issue": "2", "section": "", "partNumber": "", "partTitle": "", "pages": "198-209", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "Renewable Power Generation, IET", "DOI": "10.1049/iet-rpg.2009.0110", "citationKey": "", "url": "", "accessDate": "", "PMID": "", "PMCID": "", "ISSN": "1752-1416", "archive": "", "archiveLocation": "", "shortTitle": "", "language": "", "libraryCatalog": "IEEE Xplore", "callNumber": "", "rights": "", "extra": "", "tags": [ { "tag": "asynchronous generators", "type": 1 }, { "tag": "doubly fed induction generators", "type": 1 }, { "tag": "electrical power systems", "type": 1 }, { "tag": "fixed-speed induction generation", "type": 1 }, { "tag": "measurement based method", "type": 1 }, { "tag": "power system measurement", "type": 1 }, { "tag": "renewable energy", "type": 1 }, { "tag": "synchronous generation", "type": 1 }, { "tag": "wavelet-based support vector data description", "type": 1 }, { "tag": "wind farm power system oscillations monitoring", "type": 1 }, { "tag": "wind power plants", "type": 1 } ], "collections": [], "relations": {}, "dateAdded": "2010-11-03T15:16:48Z", "dateModified": "2010-11-03T15:16:48Z" } }, { "key": "WZIXPTU8", "version": 1, "library": { "type": "group", "id": 30476, "name": "GSC Potencia Efecto torre", "links": { "alternate": { "href": "https://www.zotero.org/groups/gsc_potencia_efecto_torre", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/30476/items/WZIXPTU8", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/gsc_potencia_efecto_torre/items/WZIXPTU8", "type": "text/html" } }, "meta": { "createdByUser": { "id": 274264, "username": "Andoni", "name": "", "links": { "alternate": { "href": "https://www.zotero.org/andoni", "type": "text/html" } } }, "creatorSummary": "Hans Ganander and Reidar Lindström", "parsedDate": "2001-08", "numChildren": 1 }, "data": { "key": "WZIXPTU8", "version": 1, "itemType": "magazineArticle", "title": "Short Term Power Variations in the Output of Wind Turbines", "creators": [ { "creatorType": "author", "firstName": "Staffan Engström", "lastName": "Hans Ganander" }, { "creatorType": "author", "firstName": "", "lastName": "Reidar Lindström" } ], "abstractNote": "Windpower engineers have some preferred explanations to various phenomena.

This paper presents a simulation model of a MW-level variable speed wind turbine with a doubly fed induction generator developed in the simulation tool of PSCAD/EMTDC. Flicker emission of variable speed wind turbines with doubly fed induction generators is investigated during continuous operation, and the dependence of flicker emission on mean wind speed, wind turbulence intensity, short circuit capacity of grid and grid impedance angle are analyzed. A comparison is done with the fixed speed wind turbine, which leads to a conclusion that the factors mentioned above have different influences on flicker emission compared with that in the case of the fixed speed wind turbine. Flicker mitigation is realized by output reactive power control of the variable speed wind turbine with doubly fed induction generator. Simulation results show the wind turbine output reactive power control provides an effective means for flicker mitigation regardless of mean wind speed, turbulence intensity and short circuit capacity ratio.", "publicationTitle": "Energy Conversion, IEEE Transactions on", "publisher": "", "place": "", "date": "2005", "volume": "20", "issue": "4", "section": "", "partNumber": "", "partTitle": "", "pages": "896-905", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "Energy Conversion, IEEE Transactions on", "DOI": "10.1109/TEC.2005.847993", "citationKey": "", "url": "10.1109/TEC.2005.847993", "accessDate": "2010-06-16T08:45:40Z", "PMID": "", "PMCID": "", "ISSN": "0885-8969", "archive": "", "archiveLocation": "", "shortTitle": "", "language": "", "libraryCatalog": "IEEE Xplore", "callNumber": "", "rights": "", "extra": "", "tags": [ { "tag": "EMTDC", "type": 1 }, { "tag": "PSCAD", "type": 1 }, { "tag": "asynchronous generators", "type": 1 }, { "tag": "control engineering computing", "type": 1 }, { "tag": "doubly fed induction generators", "type": 1 }, { "tag": "flicker emission", "type": 1 }, { "tag": "grid connection wind turbines", "type": 1 }, { "tag": "power generation control", "type": 1 }, { "tag": "power grids", "type": 1 }, { "tag": "power system CAD", "type": 1 }, { "tag": "power system interconnection", "type": 1 }, { "tag": "reactive power control", "type": 1 }, { "tag": "short circuit capacity", "type": 1 }, { "tag": "short-circuit capacity ratio", "type": 1 }, { "tag": "variable speed wind turbines", "type": 1 }, { "tag": "wind turbines", "type": 1 }, { "tag": "wind turbulence intensity", "type": 1 } ], "collections": [], "relations": { "owl:sameAs": "http://zotero.org/groups/20338/items/KK2ZXXZR" }, "dateAdded": "2010-11-03T15:14:07Z", "dateModified": "2010-11-03T15:14:07Z" } } ]
