The work presented in this paper utilizes the inherent reactive power capability of the doubly-fed induction generator (DFIG) based wind farms to optimize the system losses while considering the network constraints in the system. The IEEE-30 bus system was modified by installing DFIG based wind farms in the medium voltage (MV) region creating three wind clusters in the network. The steady-state analysis was conducted to illustrate the loss minimization capability of the DFIG based wind farms under different reactive power configurations. Reactive power participation for loss minimization was derived for each individual DFIG based wind farm to limit the control burden for the system operator and has shown the loss minimization performance for a range of wind farm control scenarios. The impact of dynamic line rating (DLR) was also investigated in the steady-state analysis and has shown that such capability can further enhance the loss reduction ability of the distributed VAr resources, in particular during high wind penetrations when transmission lines are heavily congested. The dynamic network analysis was carried out considering the Northern Ireland demand and wind power generation profiles with uniform and non-uniform wind conditions for three wind clusters defined in an IEEE-30 bus system. The dynamic network study has also shown that significant energy savings can be achieved by optimized reactive power dispatch of distributed VAr resources.","PeriodicalId":159104,"journal":{"name":"2011 IEEE Power and Energy Society General Meeting","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122210787","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 northwest region of China, the planned capacity of onshore wind farms has reached over 20GW in total. However, the locations of those wind farms are very remote and far away from load centers, and their distance to load centers are beyond 1000km. Therefore, it's of primary importance to address the issues concerned with bulk wind power transmission over long distance. This paper is aimed at development and application of using the line-commutated converter based multi-terminal HVDC (LCC-MTDC) technology for grid integration of large remote onshore wind farms located at Northwest China region. The studies have firstly focused on the design of LCC-MTDC system configuration and its parameters, taking into consideration the practical operation requirements for wind farm grid integration. The control strategy for the LCC-MTDC operation is then proposed, and the comparison in control strategy with and without coordinated operation is also carried out and verified by PSCAD/EMTDC simulation. Various operation scenarios such as ac fault on rectifier and inverter sides are simulated to investigate the system performance during disturbances. Results show that the proposed LCC-MTDC configuration and its control strategy are effective and the LCC-MTDC system is well controlled over the whole operating range.","PeriodicalId":159104,"journal":{"name":"2011 IEEE Power and Energy Society General Meeting","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128788446","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}
