Traditionally the back-to-back converters are used to excite the rotor circuit of DFIG. In this paper, instead an Indirect Matrix Converter (IMC) is used to control the generator. Compared with back-to-back converters, IMCs have numerous advantages such as: higher level of robustness, reliability, reduced size and weight due to the absense of bulky electrolytic capacitor. Maximum Power Point Tracking (MPPT) is an important issue in wind turbines to capture the maximum power from the wind. A laboratory scale prototype of DFIG wind turbine controlled by the IMC is manufactured. Experimental results confirm the effectiveness of the proposed method.","PeriodicalId":207212,"journal":{"name":"2016 Iranian Conference on Renewable Energy & Distributed Generation (ICREDG)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130726868","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}

In order to have a profitable and efficient wind energy harvesting system, wind turbines should continuously operate at maximum power point under wind velocity variations. This paper proposes a very fast and high-efficient Maximum Power Point Tracking (MPPT) control method for variable speed wind turbines. This control strategy possess a variable structure based on sliding mode control and could be simply implemented on a Wind Energy Generation System (WEGS). The main components of a WEGS are introduced and detailed theoretical analyses are presented. The verification of the theoretic analysis is done through simulating a 2.7 MW variable-speed PMSG based WEGS being controlled by the proposed controller.","PeriodicalId":207212,"journal":{"name":"2016 Iranian Conference on Renewable Energy & Distributed Generation (ICREDG)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122264767","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}
